Corrosion resistance of silicon carbide radiant tube

The fire resistance and high temperature resistance of silicon carbide is very practical, and has been used more and more widely in daily life. Today, we introduce the corrosion resistance characteristics of silicon carbide radiant tube.

As we all know, the chemical corrosion resistance of silicon carbide products is relatively high, which is mainly due to the high affinity of silicon carbide for oxygen. The reaction between silicon and oxygen in aqueous medium causes passivity. If the silicon oxide products are oxidized, the oxidation can be further prevented. The material migration of the outer layer is only carried out by non-ionic oxidation Even at 1500 ℃, the oxidation resistance of pure silicon carbide is twice as high as that of today’s alloys at 1200 ℃.

Because most of the silicon carbide radiant tubes are high value-added products, the market prospect is broad and broad, so it has been recognized by many countries. It has always been studied by the material science field. How to make high-density silicon carbide ceramics is also a topic of concern to researchers. High strength can be obtained after cold working of springs, kitchen utensils, components, buildings and vehicles, but the elongation is inferior to that of steel. The influence of these factors on the function was discussed by testing the change of temperature and the change of loading speed. Austenitic stainless steel austenitic stainless steel is the main type of stainless steel, its output and consumption account for 70% of the total stainless steel.

Another method: carbon and silicon metal directly reflect the formation of silicon carbide radiant tube, that is, carbon or carbon and silicon carbide molding, buried silicon burning. However, in higher concentration scale, carbon steel is usually used. The company will face the competition from domestic and international manufacturers of other related products, and the competition is increasingly fierce. The metals buried in the soil, depending on the sky and other elements, are in a complex situation of transformation at any time.
