304 stainless steel wire mesh surface quality how to control?

304 stainless steel wire mesh appearance quality is good or bad, mainly determined by the heat treatment and pickling process of stainless steel wire, if the heat treatment process formed by the thickness of the oxygenized skin curled edge, thick place and thin place base metal surface roughness Not the same, the pickling process can not improve the roughness of its appearance, so in order to control the appearance quality of stainless steel wire, we must strictly control the two procedures of heat treatment and pickling.
 
How to make the oxygenation skin of heat treatment spread evenly? To achieve this, we must pay attention to the following issues:
 
If the stainless steel wire adheres to the surface when it is hot, the oxygenized skin will not be the same thickness as the place where there is no oil, and it will be carburized. Oxygenation of the subcutaneous metal can cause acid corrosion in the pickling process. Stainless steel wire is not touched by hand in heat treatment, because the fingerprint will also affect the quality of oxygenated skin of heat treatment.
 
If the stainless steel wire is found to have oil stains before it is processed at a high temperature, it must be fully degreased in the trichloroethylene degreasing agent and caustic soda solution and then washed with warm water before heat treatment is performed.
 
304 stainless steel wire mesh furnace atmosphere is not the same in all parts, the formation of oxygenized skin will also have changes, which is also caused by pickling edge after pickling. Therefore, when heating, the atmosphere in each part of the furnace must be the same. For this reason, it is also important to think about the cycle of problem atmosphere.
