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 for processing stainless steel plate in the cold rolling machine, for the smoothness and cooling of stainless steel plate plays a very important role, but the emulsion contains the composition of oil, experienced people know that the oil will be cracked into carbon at high temperature.
If the oil in the emulsion can not be removed in time after high temperature into carbon, it will backlog on the surface of 304 stainless steel pipe fitting, and indentation will be formed after rolling.
Due to a lot of oil content in the emulsion, after the annealing of the inner wall of the maintenance cover will form carbonization accumulation in the inner wall of the maintenance cover. In other processing processes, the carbon black will be brought to the surface of 304 stainless steel pipe fittings, so as to cover the surface of 304 stainless steel pipe affecting the appearance quality. After a long time of processing operations, the convection plate and stove will accumulate a lot of oil, carbon black and dust and other debris, such as fruit is not cleaned up in time, also will fall on the surface of the stainless steel plate. In fact, in the final analysis, the chemical composition and surface finish of 304 stainless steel pipe fittings and manufacturing environment and cleanliness is very much related to, as long as the convection plate, stove and maintenance cover wall clean, can indirectly improve the quality of 304 stainless steel pipe surface.
