不锈钢无缝管热处理时怎么清理表面?

不锈钢无缝管表面工艺的处理也决定了无缝管的质量,一根不锈钢无缝管的表面质量取决于其热处理的过程。若果热处理工艺不当,会导致不锈钢无缝管表面氧化膜不均匀,这样在酸洗时就容易造成不均匀。

The surface treatment of stainless steel seamless pipe also determines the quality of seamless pipe. The surface quality of a stainless steel seamless pipe depends on its heat treatment process. If the heat treatment process is improper, the oxide film on the surface of stainless steel seamless tubes will be uneven, which is easy to cause uneven during pickling.

1、不锈钢的工件上的表面有杂物,在加热时对氧化膜有一定的影响,所以加热前一定要等到杂物落定后清除。

The surface of the workpiece, 1 stainless steel on the debris, have a certain impact on the film when heated, so before heating must wait until after the removal of debris settles.

2、处理件的局部在热处理前还有残存的氧化皮,那么在加热后就会有氧化皮残存的部位和没有氧化皮的部位,那么就会出现氧化皮的厚度和成分上的差异,进而就会导致酸洗后表面不均匀。

2, the local treatment prior to heat treatment and residual oxide, then after heating will be oxidized residual parts and parts without oxide, then there will be differences in the composition and thickness of oxide on the surface after pickling, which will lead to uneven.

3、佩戴清洁手套操作。在加热时工件表面附着油,油附着部位的氧化皮厚度和其他部分的氧化皮厚度和组成不同的话,那么就会产生渗碳。而氧化皮下的基体金属就会被渗碳的部分严重地受到酸的侵蚀。因此,操作大员千万不要用手去直接的触摸不锈钢件,也不要让工件上沾上新的油污。

3. Wear clean gloves. When heating the workpiece is attached to the surface of oil, oil adhesion of oxide thickness parts and other parts of the oxide thickness and composition of different words, it will produce carburizing. The oxidized subcutaneous matrix metal is heavily corroded by acid. Therefore, the operation of members do not use the hand to touch the stainless steel parts directly, also don't let the workpiece with new oil.

4、处理件不直接接触火焰口。气休或者油的火焰直接接触的不锈钢表面和没接触的地方所产生的氧化皮是有一定的差异的。

4, the processing parts do not directly touch the flame port. Oxide produced by stainless steel surface and no contact where direct contact gas or oil flame is there is a certain difference.
