标起重圆环链条在起重链条的规格工艺方面，是有相关规范的，杭州雄盛机械厂通过尺寸和材质两方面进行介绍国标起重圆环链条的正确选用和国标起重圆环链条规格。

 

Hangzhou Xiongsheng machinery factory introduces the correct selection of the national standard lifting ring chain and the national standard lifting ring chain specifications through the dimensions and materials.

 

 

 

尺寸1、材料直径

 

Size 1, material diameter

 

 

 

成品链环的任一截面的材料直径应等于名义尺寸，其公差应符合相关标准的要求。测量时，应取同一截面内互相垂直的两次测量结果的平均值。测量时应避开焊缝，且在链环直边上，避免由于链条芯模接触引起截面的变形影响测量结果。

 

The material diameter of any section of the finished chain link shall be equal to the nominal dimension, and its tolerance shall meet the requirements of relevant standards. During the measurement, the average value of two measurement results perpendicular to each other in the same section shall be taken. The welding seam shall be avoided during the measurement, and the deformation of the section caused by the contact of the chain core die shall not affect the measurement result on the straight edge of the chain link.

 

 

 

2、链环的其他尺寸 链环的长度、宽度以及高精度链条的节距和若干个链环的长度均应符合相关标准的规定。

 

2. The length and width of other sizes of links, the pitch of high-precision chain and the length of several links shall comply with the relevant standards.

 

 

 

材质、热处理和制造 1、材质 链条的材质应符合相关标准的要求。

 

Material, heat treatment and manufacturing 1. The material of material chain shall meet the requirements of relevant standards.

 

 

 

在满足这些要求的前提下，制造商应选择一种钢材，以便成品链条符合相关标准的机械性能要求。

 

On the premise of meeting these requirements, the manufacturer shall select a steel so that the finished chain can meet the mechanical performance requirements of relevant standards.

 

 

 

 

 

 

2、热处理 所有链条在施加制造验证力之前，都应按相关标准的规定进行热处理。

 

2. Heat treatment all chains shall be subject to heat treatment according to relevant standards before applying Manufacturing Verification force.

 

 

 

3、制造 3.1、制造工艺 平型或非对称型焊缝均应位于链环的中部。在链环分肢中部的任一侧，焊接影响的材料尺寸均不应超过相关标准的规定值。

 

3. Manufacturing 3.1. The manufacturing process of flat type or asymmetric type welds shall be located in the middle of the chain link. On either side of the middle part of the link leg, the material size affected by welding shall not exceed the specified value of relevant standards.

 

 

 

焊缝在任何地方都不应错位到使链环外廓产生凹陷。 3.2、修整 3.2.1、平型焊接链 应清除焊接形成的凸棱。3.2.2、非对称焊接链

 

The weld shall not be misplaced in any place to make the outer outline of the link concave 3.2. Trimming 3.2.1. The convex edges formed by welding shall be removed from the flat welding chain. 3.2.2 asymmetric welding chain

 

 

 

应清除链环外表面由于焊接形成的凸棱，保留内表面凸棱。

 

The convex edges on the outer surface of the chain link due to welding shall be removed and the convex edges on the inner surface shall be reserved.

 

 

 

4、表面状态 如果有涂层，成品链条应包括表面涂层。

 

4. If there is coating on the surface, the finished chain shall include the surface coating.

 

 

 

5、制造验证力(MPF)

 

5. Manufacturing Verification force (MPF)

 

 

 

热处理及工艺处理完毕，成品链条应经受相关标准规定的制造验证力。试验机应符合附录A的要求。链条放入试验机时应无扭转。验证力除去后，应由胜任者仔细检验，更换不合格的链环。当拨动链条时，链条应转动灵活。

 

After heat treatment and process treatment, the finished chain shall be subject to the manufacturing verification force specified in relevant standards. The testing machine shall meet the requirements of Appendix A. The chain shall not be twisted when put into the testing machine. After the verification force is removed, the competent person shall carefully inspect and replace the unqualified chain link. When the chain is moved, it should rotate flexibly.

 

 

 

采用酸洗或电镀等表面处理工艺时，链条有发生脆性的危险，应对成品链重新施加制造验证力。为了检验施加验证力后的链条，应提供合适的设备和照明。

 

When the surface treatment process such as pickling or electroplating is adopted, the chain is in danger of brittleness. The manufacturing verification force shall be applied to the finished chain again. Suitable equipment and lighting shall be provided to verify the chain after application of the verification force.

 

 

 

6、制造过程中接入的链环

 

6. Links connected in the manufacturing process

 

 

 

任何接人的链环应进行处理以保证成品链条中的每个链环具有同样状态。如果链环在施加制造验证力后接入，则受接入处理影响的那部分链条应重新经受制造验证力和检验。

 

The links of any successor shall be treated to ensure that each link in the finished chain has the same status. If the link is connected after applying the manufacturing verification force, the part of the chain affected by the connection processing shall be subjected to the manufacturing verification force and inspection again.

 

 

 

7、破断力(BF)和总极限伸长率(A) 成品链条的破断力和总极限伸长率至少应满足相关标准规定的要求。

 

7. The breaking force (BF) and total ultimate elongation (a) of the finished chain shall at least meet the requirements of relevant standards.

 

 

 

8、弯曲 成品链环的小抗弯性应符合相关标准的规定。

 

8. The minimum bending resistance of the bent finished chain link shall meet the requirements of relevant standards.

 

 

 

大多数链条已列为国际标准，发达国家国家标准或中国标准，这些链条的链号标识，不难从标准中查到。然而在链条国际贸易交往中，常常流行着美国、日本、德国、意大利、比利时等的链条企业链号，使得我们的链条企业家们望之茫然无对，束手无策。

 

Most chains have been listed as international standards, developed country standards or China national standards. The chain number identification of these chains is not difficult to find from the standards. However, in the chain international trade, the chain enterprise chain numbers of the United States, Japan, Germany, Italy, Belgium and other countries are often popular, which makes our chain entrepreneurs at a loss and helpless.
