Factors affecting the surface quality of 304 stainless steel pipe fittings

One of the important factors affecting the surface quality of stainless steel pipe fittings is that the oil content of the emulsion is too high. The emulsion is a necessary solution when processing stainless steel plates in cold rolling mills, and plays an important role in the smoothness and cooling of stainless steel plates. , but the emulsion contains oil components, and experienced people know that oil at high temperatures will crack into carbon.
If the oil in the emulsion cannot be removed in time after being carbonized at high temperature, it will accumulate on the surface of 304 stainless steel pipe fittings, and indentations will be formed after rolling.
Due to the high oil content in the emulsion, after annealing the inner wall of the maintenance cover, carbonization will be formed and deposited on the inner wall of the maintenance cover. During other processing, these carbon blacks will be brought to the surface of the 304 stainless steel pipe fittings to cover the The surface of 304 stainless steel pipe affects the appearance quality. After a long period of processing, a lot of oil, carbon black, dust and other sundries will accumulate on the convection plate and the stove top. If they are not cleaned in time, they will also fall to the surface of the stainless steel plate. In fact, the chemical composition and surface finish of 304 stainless steel pipe fittings have a lot to do with the manufacturing environment and cleanliness. As long as the convection plate, furnace table and inner wall of the maintenance cover are cleaned in time, the surface quality of 304 stainless steel pipes can be indirectly improved. .
