How to control the surface quality of 304 stainless steel wire mesh?

The quality of 304 stainless steel wire mesh is mainly determined by the heat treatment and pickling process of stainless steel wire. If the thickness of the oxygenated skin formed by the heat treatment process is sharp, the thick metal and the thin place are rough. Different degrees, the pickling process cannot improve the roughness of its appearance, so in order to control the appearance of stainless steel wire, we must strictly observe the two procedures of heat treatment and pickling.

How to make the oxygenated skin of the heat treatment spread evenly? To do this, be sure to pay attention to the following questions:

If the stainless steel wire is attached to the oil stain when it is heat treated, the oxygenated skin will be different in thickness from the place where there is no oil stain, and it will carburize. The oxygenated subcutaneous metal will corrode the acid in the pickling process. Stainless steel wire should not be touched by hand during heat treatment, because fingerprints will also affect the quality of oxygenated skin for heat treatment.

If the stainless steel wire is found to have oil stains before high-temperature processing, it must be fully degreased in trichloroethylene degreaser and caustic soda solution, then rinsed with warm water, and then heat treated.

The atmosphere in the 304 stainless steel wire mesh furnace is different in each part, and the formation of the oxygenated skin will also change, which is also the end of the ribs after pickling. Therefore, when heating, the atmosphere of each part of the furnace must be the same. To this end, it is also necessary to think about the cycle of the problem atmosphere.
