There are many types of stainless steel pipes. Commonly used ones can be divided into stainless steel round pipes, square pipes, hexagonal pipes, etc. according to their shapes. According to their uses, they can be divided into stainless steel industrial pipes, thick-walled pipes, welded pipes, etc. Weite mainly sells 304 stainless steel capillary pipes of various materials and specifications.
Do you know what affects the quality of the surface of stainless steel capillaries? As a kind of stainless steel seamless pipe in austenite, 304 stainless steel capillaries not only have good basic mechanical properties such as tensile resistance, corrosion resistance and high hardness, but also have a beautiful appearance, which means that the brightness of the surface of 304 stainless steel capillaries reaches the standard height. However, it should be noted that the brightness of 304 stainless steel capillaries will be reduced due to improper operation or poor preparation during processing.
One of the important factors affecting the surface quality of stainless steel capillaries is that the emulsion has too high oil content. The emulsion is a necessary solution for the cold rolling mill to process stainless steel capillaries. It plays an important role in the smoothness and cooling of stainless steel capillaries. However, the emulsion contains oil, and the oil will crack into carbon at high temperature. If the oil in the emulsion is not cleaned up in time after being carbonized at high temperature, it will accumulate on the surface of the 304 stainless steel capillary, and an indentation will be formed after rolling. Due to the high oil content in the emulsion, carbonization will be formed and accumulated on the inner wall of the maintenance cover after annealing. In other processing processes, these carbon blacks will be brought to the surface of the 304 stainless steel capillary, thereby covering the surface of the 304 stainless steel capillary and affecting the appearance quality. After a long period of processing, a lot of oil, carbon black, dust and other debris will accumulate on the convection plate and the furnace. If they are not cleaned in time, they will also fall on the surface of the stainless steel capillary.
In fact, the chemical composition and surface finish of 304 stainless steel capillaries are closely related to the manufacturing environment and cleanliness. As long as the convection plate, furnace table and the inner wall of the maintenance cover are cleaned in time, the surface quality of 304 stainless steel capillaries can be indirectly improved.
Keeping the surface of stainless steel capillaries clean can effectively extend the service life of stainless steel capillaries, save costs and create greater use value.
