NEWS Effect of Carburizer Particle Size on Absorption Rate The carburizing process using a carburant includes a dissolution diffusion process and an oxidation loss process. The particle size of the carburant is different, the dissolution diffusion rate and oxidation loss rate are also different, and the absorption rate of the carburant depends on the combined … Continue reading "Effect of Carburizer Particle Size on Absorption Rate"

NEWS Why Adding Carnon Additive in Steelmaking Process? It is generally believed that the higher the temperature of molten iron, the longer the action time, and the higher the carbon absorption rate. But the reality is just the opposite. In the induction furnace, carbon is increased at low temperature and silicon is increased at high … Continue reading "Why Adding Carnon Additive in Steelmaking Process?"

NEWS Influence and Application of Carbon Raiser in Smelting Industry With the same chemical composition, different smelting processes, different ingredients and ingredient ratios, the metallurgical quality of molten iron is completely different. To obtain a good carburizing effect, the electric furnace adopts the carburizing technology, and the cupola adopts the high-temperature smelting technology. The influence … Continue reading "Influence and Application of Carbon Raiser in Smelting Industry"

NEWS Advantages of Adding Carburant During Smelting There are many coarse hypereutectic graphites in pig iron. This kind of coarse graphite is hereditary, the melting temperature is low, and the coarse graphite is not easy to be eliminated. The coarse graphite is inherited from the liquid state to the solid cast iron structure. On the … Continue reading "Advantages of Adding Carburant During Smelting"

NEWS The Choice of Carbon Raiser and its Character During the smelting process, due to improper ingredients or charging and excessive decarburization, sometimes the carbon content in steel or iron does not meet the expected requirements. At this time, carbon should be added to steel or molten iron. The main substances usually used to increase … Continue reading "The Choice of Carbon Raiser and its Character"

NEWS Influence of Carburizer on Structure and Properties of Cast Iron The influence of carburizing process on cast iron structure After carburizing with carbon additive, a large number of dispersed heterogeneous crystallization cores are formed in the molten iron, which reduces the supercooling degree of the molten iron and promotes the formation of A-type Graphite-based graphite … Continue reading "Influence of Carburizing Process on Structure and Properties of Cast Iron"

NEWS Smelting Process of Silicon Metal for Chemical Industry The technological process of silicon for chemical use includes furnace charge preparation, electric furnace smelting, silicon refining and casting, and crushing for removing slag inclusions. All raw materials must undergo necessary treatment before the charge is prepared. The silica is crushed in the jaw crusher until … Continue reading "Smelting Process of Silicon Metal for Chemical Industry"
