As a kind of austenitic tube, 304 stainless steel pipe has basic mechanical properties such as good wear resistance, corrosion resistance, and high hardness, but also has a high-quality appearance, that is to say, the brightness of the surface of the 304 stainless steel pipe It must reach the standard height, but due to improper operation or poor preparation during the processing, the brightness of the 304 stainless steel pipe will be reduced, so attention should be paid.
One of the important factors affecting the surface quality of stainless steel pipes is that the oil content of the emulsion is too high. The emulsion is a necessary solution when the cold rolling mill runs and processes the stainless steel plate. It plays an important role in the smoothness and cooling of the stainless steel plate. However, the emulsion contains oil components, and experienced people know that oil at high temperature will be cracked 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 the 304 stainless steel pipe, and indentation will be formed after rolling. Due to the high oil content in the emulsion, after annealing the inner wall of the maintenance cover, it will form carbonization and accumulate 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, thereby covering The surface of the 304 stainless steel pipe affects the appearance quality. After a long period of processing, a lot of oil, carbon black, dust, and other debris will also accumulate on the convection plate and the stove. If it is not cleaned in time, it will also 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 has a great relationship with the manufacturing environment and cleanliness. As long as the convection plate, stove, and maintenance cover are cleaned in time, the surface quality of 304 stainless steel pipe can be indirectly improved.
