Factors influencing the surface quality of 304 stainless steel pipe fittings

DataTime:[2016-4-3]

One of the important factors affecting the quality of the surface of the stainless steel pipe is excessively high oil content of the emulsion, the emulsion is processed at the time of cold rolling mill operation was necessary stainless steel plate, stainless steel plate for cooling smoothness and play an important role But people emulsions containing oil components, experienced all know, oil at high temperature will cleaved into carbon.
Oil emulsion if not promptly cleared after a high temperature into carbon, will backlog in 304 stainless steel surface, will form the impression after rolling. Since the oil content of the emulsion within the lot, after annealing maintenance cover wall will form carbide deposited on the inner wall of the maintenance cover, among other processes, these carbon 304 stainless steel pipe will be brought to the surface area, so as to cover the 304 stainless steel tube surface affect the appearance of quality.
After a long period of processing operations, the convection plate and the hob will accumulate a lot of oil, carbon black and dust and other debris, if not cleared up, the same will fall to the surface of the stainless steel plate.

In fact, the chemical composition of the final analysis, 304 stainless steel pipe fittings and surface finish and cleanliness of the manufacturing environment is a great relationship, as long as timely convection plate, stove and clean the inner wall of the maintenance cover can indirectly improve the quality of the surface of 304 stainless steel pipe.
