304 stainless Steel pipe has good corrosion resistance, stretchability and aesthetics, so it is widely used in all walks of life, but there are also many problems that make its surface brightness low and poor quality.
1. The emulsion has high oil content
Emulsion is a necessary solution when the cold rolling mill is running and processing stainless steel plates. It plays an important role in the smoothness and cooling of the stainless steel plates. However, the emulsion contains oil components, and the oil at high temperature will be cracked into carbon. The oil in the emulsion will accumulate on the surface of the 304 stainless steel pipe if it cannot be cleaned up after being carbonized at a high temperature, and indentation will be formed after rolling.
2. The environment of 304 stainless steel pipe
The chemical composition and surface finish of 304 stainless steel pipe have a great relationship with the manufacturing environment and cleanliness. Timely cleaning the convection plate, stove top and the inner wall of the maintenance cover can indirectly improve the surface quality of the 304 stainless steel pipe.
3. Other situations
During the processing, some carbon black will adhere to the surface of the 304 stainless steel pipe and affect the appearance quality of the 304 stainless steel pipe. After a long period of processing operations, a lot of oil, carbon black, dust and other debris will also accumulate on the convection plate and stove. If it is not cleaned up in time, it will also fall on the surface of the stainless steel plate.
The surface quality of 304 stainless steel pipe is not only affected by the above factors, but also storage environment and transportation conditions.
