Annealing Boxes for a defined Protective Atmosphere for use in Chamber and Pit-Type Furnaces with Air Circulation

Annealing Boxes for Models N 30/45 HA - N 500/85 HA, S 30/45A - S 500/85AUsing annealing boxes, you can operate our standard air circulation furnaces, modelsN 30/45 HA - N 500/85 HA and models S 30/45 A - S 500/85A, under a defined protective atmosphere. This allows processes such as bright annealing, annealing under protective gas, or curing of copper alloys.

On standard models, the boxes are equipped with a lid and a protective gas inlet and outlet. The lid is sealed by means of a sealing groove with a fibre gasket before loading into the furnace. The furnace is equipped with a special pass-through for the box inlet and outlet connections. The box inlet is connected to a gas supply panel. We have gas supply panels available for either manual or automatic control.

As a vacuum model, the box allows air evacuation in cold condition before refilling with protective gas. This system is particularly useful for bright annealing of bulk materials, since the oxygen can be more efficiently removed from the box by means of pre-evacuation than through purging alone. In our modern research center we can carry out tests and experiments to demonstrate how these boxes perform with your materials.

Ship-lock type furnace N 560/�6HACLS with safety technology, front charging and rear unloading

Safety Technology for Chamber FurnacesCertain processes release solvents or evolve other flammable vapors when heat is applied. The concentration of these vapors must be kept below a certain limit to prevent ignition. European Norm EN 1539 (formerly VGB4) and NFPA 86 in the USA proscribe the required safety equipment for these processes.

For appropriate applications and processes, all air circirculation furnaces of the series N ..HACLS (pages 10, 11 and 13) are available with safety technology for protection of ignition in the furnace chamber.

To prevent ignition, flammable vapors must be diluted with air. Special care must be taken so high concentrations of flammable materials do not accumulate in “dead” areas within the furnace. For this purpose, the furnaces are equipped with an exhaust gas fan, providing a defined suction flow. A measurement system monitors this flow. In parallel, the furnace atmosphere is diluted by the inflow of fresh air. The air circulation is also monitored by the measurement system. Furnaces with a capacity greater than 1000 liters are additionally equipped with an explosion pressure relief.

Our protective gas and carburization modules allow you to upgrade our annealing and hardening furnaces into a compact annealing and hardening system as an economical alternative to expensive vacuum systems and protective gas furnaces. We can recommend different systems based on your application. Our professional R & D department will be pleased to test your product samples in order to specify the right heat treatment equipment for you.

Annealing BoxOur annealing boxes with lid sealing may be used for carburizing, annealing and hardening in neutral atmospheres, powder nitriding or boriding. Your charge is placed in the box and bedded in carburizing granulate, neutral annealing coal or nitriding or boriding powder. The box is sealed, and when heated, the resulting atmosphere in the closed annealing box provides for the respective surface reaction of the charge. For carburizing and similar processes, the annealing box may be removed while hot, opened and the charge quenched in fluid. For annealing processes, the box may remain in the furnace until it is cooled down.

Annealing Tray with Alloy BagThis system, consisting of a lightweight tray with gas port and alloy bag, is particularly useful for air-quenched steels. The thin-walled alloy bag allows fast heat transfer. Its protective gas connections allow you to process your charge in a defined atmosphere. The small size of the gas lightweight tray you to pre-flush or cool the unit outside the furnace or place it on a cooling table for fast cooling by fan.

Annealing Box with Protective Gas Inlet and Outlet The boxes are equipped with lid and protective gas inlet and outlet. The lid is sealed by means of a sealing channel with a high-temperature rope gasket before it is introduced into the furnace. The furnace is equipped with a special passage for the protective gas connections. The box is connected to a gas supply panel to introduce the required atmosphere in the box. When the heating process is finished, the box may be removed from the furnace, the lid removed and the parts quenched in liquid or air.

Annealing Box with Protective Gas Inlet and Outlet constructed for Evacuation Ambient TemperaturesThis version of our annealing box is designed to be evacuated prior to the heating cycle. After evacuation, the box is refilled with a protective atmosphere for the heating cycle. This system is particularly useful for bright annealing of bulk materials, and nonferrous and noble metals, since oxygen can be more efficiently removed from the box by evacuation than through purging. Temperature-resistant seals allow this version of the annealing box to maintain a vacuum at ambient temperatures.

Additional AccessoriesIn addition to the above-mentioned protective gas and carburization systems, Nabertherm has a variety of heat treatment accessories ranging from the sealing cords for the annealing boxes to fully automatic gas supply panels. Ask for our Heat Treatment II Catalog.

MHS 17

MHS 17Our tool shop hardening system MHS 17 allows you to easily handle your entire heat treatment needs on your own. The modular system consists of a table with one furnace for hardening and one for tempering, and oil and water quench tanks. For hardening you can choose between 4 furnaces N 7/H - N 17/HR, with the HR series having more power for faster heating rates. Furnace N 15/65 HA with air circulation is used for tempering. Of course, you may buy each of these components separately. All accessories necessary for the hardening process are also available (see also page �5). Ask for our extensive hardening catalog.

Additional EquipmentThe tool shop hardening system MHS 17 can be upgraded with an air quenching system. When used with the annealing tray system on page ��, it allows for fast cooling while maintaining the protective atmosphere. Oil and water quench tanks can be mounted on both sides of the frame of the air quenching system.

Protective Gas Hardening System

Besides our annealing and hardening furnaces, we have a wide range of accessories for thehardening shop.

SHS 41This compact system is very suitable for hardening under protective atmosphere and subsequent quenching of the charge under protective gas in oil. Hence, this system can be used for hardening processes that would otherwise require complex furnace systems. In our modern research center we can carry out tests and experiments with different materials to specify the right heat treatment process for you.

An annealing box with protective gas port containing the work pieces is charged into the furnace. After finishing the heat treatment, the box is extracted out manually and placed onto the quenching facility. Reaching the rear trigger, the box bottom automatically lowers into the hardening oil, and is moved up and down. The space above the oil surface is flushed with protective gas to displace oxygen in order to avoid ignition.

Salt-bath hardening in practice

Martempering Furnaces using Neutral Salts

WB 10 - WB 400WB 10 - WB 400 martempering furnaces are filled with neutral salt and offer remarkably rapid and intensive heat transmission to the workpiece while ensuring optimum temperature uniformity. For working temperatures at between 180 °C and 500 °C these furnaces are ideal for quenching or cooling with minimal workpiece distortion, retempering, austempering for optimal toughness, recrystallization annealing after electrical discharge machining (EDM) and for blueing.

The quenching or cooling process is applied in order to achieve an even temperature uniformity throughout the workpiece's entire cross-section before the formation of martensite and to avoid distortion and formation of cracks in valuable mechanical components during the subsequent hardening process.

Tempering in a martempering bath is the same as the tempering process in air circulation furnaces and is used to reduce a previously hardened workpiece to a desired hardness, to increase toughness and reduce stress within the workpiece.

Austempering is a good choice to achieve a high level of toughness and dimensional accuracy in oil hardened low-alloy steels. Workpieces subject to austempering have high tensile strength and good elasticity.

Fully automated Furnace Plant consisting of 8 x W 1280/70ASThis fully automated tempering plant consisting of 8 air circulation bogie hearth furnaces, two cooling stations and loading and unloading facilities, Nabertherm offers an ideal solution for many heat treatment processes. The loading and unloading stations buffer the continuous processes before and after the heat treatment system. If necessary, the plant can be equipped with exhaust gas treatment facilities including after burner systems.

After the operator has released the fully loaded bogie at the charging station, the system runs automatically without further operator intervention. The shuttle delivers the charge into the selected furnace. With the electro-hydraulic lifting doors closed, the heat treatment process starts. When the �4 hour long temperature program is finished, the charge is transferred into one of the two cooling stations, where it stays until a safe handling temperature is reached. The shuttle then transports the charge to the unloading facility. If the facility is occupied the charge will be stored on a buffer station until the unloading area is available. The Software Nabertherm Control Center (NCC) takes care of control, visualization and documentation.

The system shown below can be expanded or adapted in modular steps to meet your individual needs.

Protective Gas Retort Furnaces with Indirect Heating Outside the Retort

N 21/M - N 321/MAThese gas-tight retort furnaces with indirect heating outside the retort are particularly suitable for heat treatment requiring a constant defined protective gas or even reactive gas atmosphere in the furnace chamber. The working chamber consists of a gas-tight retort with water cooling in the door area to protect the special seal.

Depending on the temperature range to be applied in the furnace, we recommend different versions for optimizing the temperature distribution. The basic furnace alone attains a temperature uniformity of ΔT 30K at temperatures above 800°C according to DIN 1705�. Additional equipment can further optimize these furnaces for reaching a temperature uniformity of up to ΔT 10K in other temperature ranges as well:

For a working range up to approx. 500°C the furnace is equipped with gas circulation with a fast running fan in the door.Between 500°C and 800°C the heating should also be divided into three zones and controlled.Above 800°C, three-zone control without gas circulation is the proper version.

The basic furnace is prepared for operation with a nonflammable protective gas. Equipment is also available for operation with other gases up to safe operation under hydrogen. By optimizing with various additional equipment, i.e. with cascade control, you can customize the furnace for the particular process. A vacuum pump can be employed to cold-evacuate the furnace, among other purposes, for reducing the gas consumption during pre-purging.

Process Control and Documentation

Nabertherm has more than 50 years of experience in design and construction of tailor-made switchgear and control systems. Our systems control the process, handling, documentation and other complex requirements. Our standard solutions take care of most applications. We can accommodate specific requirements, including using company-specified products or conforming to national or third-party standards.

Standard ControllersOur extensive line of standard controllers satisfies most customer requirements. Based on the specific furnace model, the controller regulates the furnace temperature reliably. The standard controllers are developed and fabricated within the Nabertherm group. When developing controllers, our focus is on ease of use. From a technical standpoint, these devices are custom-fit for each furnace model or the associated application. From the simple controller with an adjustable temperature to the control unit with freely configurable control parameters, stored programs, PID microprocessor control with self-diagnosis system and a computer interface, we have a solution to meet your requirements.

Mains voltages for Nabertherm furnaces1-phase: all furnaces are available for mains voltages from 110 V - �40 V at 50 or 60 Hz.3-phase: all furnaces are available for mains voltages from �00 V - �40 V or 380 V - 480 V, at 50 or 60 Hz.

HiProSystems Control and DocumentationThis professional control system for single and multi-zone furnaces is based on Siemens hardware and can be adapted and upgraded extensively. HiProSystems control is used when more than two process-dependent functions, such as exhaust dampers, cooling fans, automatic movements, etc., have to be handled during a cycle; when furnaces with more than one zone have to be controlled; when special documentation of each batch is required and when remote telediagnostic service is required. The system is also perfectly suited for controlling multiple furnaces or furnace groups. It is flexible and is easily tailored to your process or documentation needs.

Alternative User InterfacesTouch panel H 700This basic panel accommodates most basic needs and is very easy to use.Touch panel H 1700Firing cycle data and the extra functions activated are clearly displayed in a table. Messages appear as text.Touch panel H 3700All functions and process data are stored and displayed in easy to read charts. The data can be exported through various interfaces (RS �3�, RS 4�� /485, USB, Ethernet TCI/IP, MPI, Profibus) to a local PC or your company network for further processing. A CF card also gives the opportunity for data storage and transfer to a PC with a card reader.Extension Package, PC-based for Control, Visualisation and Documentation Nabertherm Control Center NCCUpgrading the HiProSystems-Control individually into an NCC provides for additional interfaces, operating documentation, and service benefits in particular for controlling furnace groups including charge beyond the furnace itself (quenching tank, cooling station etc.):
