工艺流程设计和开发Production process design and development

玛切嘉利中国制造的高质量产品适用范围广泛，尤其适合

原始设备制造商客户。为了向此类客户提供更好的产品质

量和更优质的服务，玛切嘉利中国公司已经开发出一套精

准的工艺流程控制体系及一套包含供应链和项目管理部在

内的特殊的组织架构。质量体系的设计和实施也是为了满

足最高标准要求。

产品设计和样品制造是向原始设备制造商客户提供新产品

的基本步骤。玛切嘉利中国公司的技术团队在为许多国际

和国内原始设备制造商客户提供新产品开发方面拥有高超

的技能和丰富的经验。

以下阐述了我公司开发新产品的主要步骤

• 首先是我们分析客户需求基于以下

- 生产制造标准

- 钢种（或化学成分）

- 机械性能

- 尺寸

- 交货状态

- 表面状况

- 检验证书

- 无损探伤测验

• 第二步是工艺研发，根据不同的产品我们有不同的工艺流程

The quality of the products manufactured by Marcegaglia China is suitable for many applications but it perfectly fit for the high requirements of OEM (Original Equipment Ma-nufactures) customers. In order to supply OEM customers with high quality and service, Marcegaglia China has de-veloped an accurate Process Control system and a special organization with Supply Chain and Project Management.

The Quality System is also designed and implemented in order to meet the highest standards.

Design and sample preparation are fundamental steps for supply new products to OEM customers. Marcegaglia China technical team has developed high skill and experience in product development for many interna-tional and domestic OEM customers.

Two are the main steps required to develop prototypes for new products:• Analysis of the customer requirements based on: - Manufacturing requirement - Steel grade (or chemical component) - Mechanical properties - Dimensions - Delivery condition - Surface conditions - Inspection certificate - NDT test• Development of the manufacturing process, which is different for each type of product.

碳钢精密焊管

• 选择合适的钢种。

根据化学机械要求甚至是粗糙度的要求，玛切嘉利将在欧标，

日标，美标及英标的基础上推荐给客户合适的原材料。

• 计算分条的合理宽度

受益于在模具加工行业的多年经验，玛切嘉利成功地设计了不

同尺寸对应准确的宽度范围的表格。

• 选择模具包括去内毛刺装置

对于不同的精整模具，我们选择不同的内毛刺刀片，通过调整

模具压力来调整内毛刺装置的高度，以此来确保焊接区域表面

平整。

• 设置焊接工艺参数

玛切嘉利有完善的数据存储系统来记录所有的焊接工艺参数，

能为将来的生产做参照。

• 通过涡流探伤来检验产品缺陷

根据客户要求或者行业规范设置验收方法。

• 验证生产工艺

通过尺寸检验来核实条宽，模具及去内毛刺加工

根据不同的钢种和标准，来做压扁/扩口试验，以此来检验焊

接质量。

针对一些特殊的产品运用比如冷拔管母管，焊缝的显微分析是

对产品性能最好的保证。

根据客户要求，可执行EN10204质保书的3.1特殊试验。

Carbon steel welded tubes (ERW)

• Choose the proper steel grade Based on the chemical, mechanical and roughness require-ments, Marcegaglia recommends the proper raw material based not only on EN standard, but also JIS, ASTM and GB standard.

• Calculate the proper width of the strips Thanks to many years of experience in tooling manufactu-ring, Marcegaglia has successfully developed rules to se-lect the exact width range for different sizes.

• Choose the tooling, including the inner scarfing tools type For different Finpass rolls, we employ different radius of the scarfing knife, adjusting its height by adjusting the tooling pressure to obtain smooth surface of the welding area.

• Set up the welding parameters Marcegaglia has a well-developed data storing system to record all the welding parameters which can be refe-rence for further production.

• Set up the acceptance level of defect by eddy cur-rent test The acceptance level is set up according to customer requirement or general norms.

• Process and production validation Dimensional test to verify the strip width, tooling and inner scarfing process.Flattening/drift expanding test according to different steel grade and also different norms to check the qua-lity of the welding.For special applications such as hollows for cold drawn tubes, a microscopic analysis of the welding section area is performed to guarantee the best performances.According to customer requirement, we can also per-form specific test 3.1 according to EN 10204.

冷拔精密管件

• 选择合适的母管

选择合适尺寸的母管，以保证缩减量处于合适的范围内

缩减量计算公式为：

Reduction rate=(100-((W1 / W2)*100))*100%W1: 成品管米重

W2: 母管米重

W1: =(OD1-T1)*T1*0.02466W2: =(OD2-T2)*T2*0.02466

• 酸洗模式选择

根据表面需求来决定是否进行磷化处理或皂化处理

• 外模/芯棒选择

外模/芯棒的形状经过严格控制

对于TTC产品（直接应用的），需要特殊的模具

• 设置去应力退火工艺参数

根据不同的客户需求，设置不同的热处理时间，冷却时间及

冷却速度。

• 验证拉拔应力

在冷拔过程中，机械应力须符合以下公式

P/F=K < δsP: 母管拉拔力

F: 成品截面积

K: 拉拔应力

δs: 成品管屈服强度


冷拔前/后进行测试来核对缩减量

去应力退火前/后进行测试来核对加热炉设置参数

根据试验数据参数来验证生产工艺

Cold-drawn tubes (DOM)

• Choose the proper hollow size The hollow size should be chosen so that the reduction rate is located in the proper range.The reduction rate is calculated with the following formula: Reduction rate=(100-((W1 / W2)*100))*100%W1: kg per meter of finish sizeW2: kg per meter of hollowsW1: =(OD1-T1)*T1*0.02466W2: =(OD2-T2)*T2*0.02466

• Select the pickling mode Based on the surface requirement, a phosphating or sa-ponification process is performed.

• Choose the die/Mandrel The shape of the die/mandrel is a critical controlled characteristic. For TTC (ready-to-use) products, special dies are required.

• Set up the Stress Relieving (SR) process parameters According to different customer requirement, a different hea-ting time, cooling time and cooling speed is set up.

• Verify the drawing stress During cold drawing, the mechanical stress should comply with the following formula:P/F=K < δsP: hollows drawing force (kgf)F: finished size section area (mm²)K: stress of drawing (kgf/mm²)δs: yield strength of finished tube (kgf/mm²)

• Process and production validation Testing is performed before/after cold drawing to verify the reduction rate. Test before/after SR to verify the furnace set-ting parameters. Process and production validation though statistic evaluation of the parameters.

冷拔焊管和无缝管的比较

相比于冷拔无缝管，冷拔焊管的优势如下：

• 更好的形状（外径和内径的圆度）

• 提高了表面质量（在涂镀和改善了疲劳寿命后）

• 获得更小的偏心率和壁厚公差（最大3%的偏心率，通常无缝

管只能保证8%）

• 更高的可靠性（管子通过100%的涡流和超声波检测来控制）

• 在低温下达到更好的韧性

基于以上优势，玛切嘉利通常在合适的前提下推荐客户使用冷

拔焊管，而事实上目前在欧洲及美国市场大多数油缸都是由冷

拔焊管制造的

Comparisons between Cold-Drawn Welded (CDW) and Cold-Drawn Seamless (CDS) tubes

The advantages of cold-drawn welded tubes when compa-red to cold-drawn seamless tubes can be summarized as: • Better geometry (OD and ID roundness)• Improved quality surface (less defect after painting and improve fatigue life)• Tighter eccentricity and wall thickness tolerances (the eccentricity is 3% max instead of 8%-10% normally guaran-teed from seamless tubes)• Higher tube safety (tubes are controlled 100% by ultraso-nic test and eddy current test)• Better toughness at low temperature

For these reasons Marcegaglia China always recommend to use CDW tubes when the thickness permits it; indeed in Europe and USA, most cylinders are produced with welded tubes.

不锈钢精密焊管

• 选择合适的钢种

根据化学机械要求甚至是粗糙度的要求，玛切嘉利将在欧标，

日标，美标及英标的基础上推荐给客户合适的原材料。
