What are the factors that affect the quality of the stainless steel capillary surface?

As we all know, stainless steel capillaries have good softness, corrosion resistance, high temperature resistance, wear resistance, tensile resistance and other properties. A small thin tube plays an indispensable role. People are emotional animals, and they often have unforgettable memories of beautiful things. What we see at a glance is not its various performances, but the surface of the stainless steel capillaries. So the question is:

Do you know what factors affect the quality of the surface of stainless steel capillaries? As a kind of stainless steel tube in austenite, 304 stainless steel capillaries not only have good tensile resistance, corrosion resistance and high hardness and other basic mechanical properties, but also have a good-looking appearance. That is to say, the brightness of the surface of 304 stainless steel capillaries reaches the standard height, but it should be noted that the brightness of 304 stainless steel capillaries will be reduced due to improper operation or poor preparation during the 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 solution that needs to be prepared when the cold rolling mill is running 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 temperatures. If the oil in the emulsion is not removed 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 accumulate 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 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 pipes, save costs and create greater use value.
