Annealing and Hardening Furnaces N 7/H - N 61/H

N 7/H as table-top model

N 7/H - N 61/HTo withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The N 7/H - N 61/H models are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation under protective gas, roller guides, or a cooling station with a quenching bath. Even high-performance applications like the annealing of titanium in medical applications can be implemented without the use of expensive and complicated annealing systems.

Gas Supply Systems / Vacuum Operation for Tube Furnaces R, RT, RS, RHTC, RHTH and RHTV

When equipped with various equipment packages, the tube furnace series RS, RHTC, RHTH, and RHTV can be adapted for operation with nonflammable or flammable gasses or for vacuum operation. The different equipment packages can be delivered together with the furnace, or later as needed.

Gas Supply System 1 for simple protective gas applications (no vacuum operation)This package represents a basic version sufficient for many applications, for operation with nonflammable protective gasses. The standard working tube made of ceramic C 530 delivered with the furnace can still be used.

Standard working tube can be used� plugs of ceramic fibre with protective gas connectionsGas supply system for nonflammable protective gas (Ar, N�, forming gas) with shutoff valve and flow meter with control valve (volume 50-500 l/hr), piped and ready to connect (gas intake pressure at 300 mbar to be provided by customer)

Additional EquipmentExtension of gas supply system with a second or third nonflammable type of gasBottle pressure regulator for use with bottled gasAutomatically controlled gas supply with solenoid valves on the gas supply panel, which can be switched on and off through a controller with programmable extra functions (e.g. P 330)

Gas Supply System 2 for protective gas applications with nonflammable gases/vacuum operationFor increased atmospheric purity requirements in the working tube, we recommend this gas supply system. The standard working tube is replaced by a dense working tube of ceramic C 610 or C 799 in a gas-tight design. Besides the longer working tube, the scope of delivery also includes gas-tight flanges and a corresponding bracket system in the furnace. The system can also be equipped for vacuum operation.

Longer, gas-tight working tube of ceramic C 610 for furnaces to 1300 °C or of C 799 for temperatures above 1300 °C� vacuum-tight, water-cooled stainless steel flanges with fittings on the outlet side (cooling water supply with NW9 hose connector to be provided by the customer)Mounting system on furnace for the flangesGas supply system for nonflammable protective gas (Ar, N�, forming gas) with shutoff valve and flow meter with control valve (volume 50-500 l/hr), gas outlet valve, piped and ready to connect (gas intake pressure at 300 mbar to be provided by customer)

With respect to the final pressure different pumps are available (see also page 44):Single-step rotary piston pump for a max. final pressure of approx. �0 mbar.Two-step rotary piston pump for a max. final pressure of approx. 10-� mbar.Pump system PT70 Dry (rotary vane pump with following turbomolecular pump for a max. final pressure of 10-5 mbar.

Information:For protection of the vacuum pump only cold stage evacuation is allowed. The reduction of working tube strengthness limits the max. possible working temperature under vacuum (see page �8).

Gas Supply System 3 for hydrogen applications, manual operation in supervised modeAdding gas supply system 3 to the tube furnace allows operation under a hydrogen atmosphere. During hydrogen operation, a safety pressure of approx. 30 mbar is ensured in the working tube. Surplus hydrogen is burnt off in an exhaust gas torch. The operator manually takes care of inerting the working chamber before process start, after process end, and in case of default.

*the max. allowed temperature might be reduced operating under aggressive atmospheres

Control Alternatives for Tube Furnaces

Furnace Chamber Control with temperature measurement in furnace chamber outside the working tube.

Advantages: Thermocouple protected against damage and aggressive load, very even control, attractive priceDisadvantage: Process-dependent temperature difference between displayed temperature on the controller and inside the tube

Charge Control with temperature measurement of load in the working tube.

Advantages: Precise control inside of tube without temperature deviationDisadvantages: Slow control with danger of temperature overshoot, control parameters must eventually be adjusted to correspond to the process. At high application temperatures, the over-temperature limit controller can activate to protect the heating elements.

Cascade Control with temperature measurement both in the furnace chamber outside the working tube as well as in the working tube.

Advantages: Very precise and rapid control adjustmentDisadvantage: Costs

Furnace Chamber vs. Cascade Controller Comparison

Furnace Chamber ControlOnly the furnace chamber temperature is measured and controlled. Regulation is carried out slowly to avoid out-of-range values. Because the charge temperature is not measured during this process, the furnace chamber temperature deviates from the charge temperature by several degrees.

Cascade ControlIf the cascade is switched on, both the charge temperature and furnace chamber temperature are measured. By setting different parameters the heat-up and cooling processes can be individually adapted. This results in a more precise temperature control at the charge.

The use of automatic valves for process gas or exhaust air management and the powerful H3700 controller allow the entire heat treatment process to be run fully automatically. The entry of all process data (temperatures, ramps, gas supply and vacuum) is easily controllable from a large, 1�" graphic control panel. System status with all process-related data are clearly shown on a process control diagram. All valves and the vacuum pump can also be operated manually from here as well.

The system has an automatic pre-program and post-program for purging the furnace chamber and also features automated leak testing.

Extension Package – Hydrogen in VHT-MO and VHT-GRWhen hydrogen is used as a process gas, our systems come equipped with additional safety technology. Only certified and industry proven safety sensors are used. The furnaces are always controlled using a fail-safe controller (S7-300F/safety controller). The controller and documentation are carried out using Nabertherm Control Center NCC (see page 51).

Two Temperature-Dependent Concepts Available for Safe Operation with Hydro-gen:

Partial pressure operation: H� infeed under controlled negative pressure (partial pressure) in the process reactor starting from 750 °C furnace chamber temperatureAtmospheric operation: H�-purging of process reactor starting from room temperature at controlled over pressure (50 mbar relative)

Extension Package – Debinding and SinteringThe "Debinding and Sintering" extension package allows VHT furnaces with molybdenum heating to be used for processes causing process-related contamination during heat treatment. The furnace is equipped with an additional retort with direct gas inlet and outlet and exhaust gas torch.Special gas plumbing prevents contamination of the furnace insulation and the heater due to the thermal process. The furnace can also optionally be equipped with a heated gas exhaust, a partial pressure debinding system, and a binding agent trap. The control system corresponds to that of the "Automatic" extension package.

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.

Measurement and Control Systems

Nabertherm has many years of experience in the design and construction of both standard and custom control system. All controls are remarkable for their ease of use and even in the basic version have a wide variety of functions.

Standard ControllerOur 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.

Assignment of Standard Controllers to Furnace Families

Mains Voltages for Nabertherm FurnacesSingle-phase: all furnaces are available for mains voltages from 110 V - �40 V at 50 or 60 Hz.Three-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.):
