The main component of the carbonizer is carbon, which is mainly used in the smelting process of steelmaking, ironmaking, and ordinary casting to add carbon to improve the quality of the finished product. The graphite carburizer produced by our company is made of pure natural flake graphite and does not add any materials to make four types of innovative products. It has the characteristics of low sulfur, low nitrogen and low moisture. When used in casting, it can increase the amount of scrap steel, reduce or even eliminate the use of pig iron, thereby greatly reducing the casting cost, improving the quality of castings, and effectively extending the service life of castings. In the process of smelting cord steel in the iron and steel group, the efficiency of using our company's graphite carburizer is significantly improved. Our carburizer has low procurement cost, meets the process quality requirements, meets the safety and environmental protection standards, excellent spreading performance, easy to dissolve, and high comprehensive carbon yield. According to the application requirements, our company can also process graphite carbonizers with double zero sulfur content.
