How to ensure the quality of recarburizer
Petroleum coke recarburizers are still used in steelmaking as smelting materials to adjust the carbon content. It is not only other industries that use petroleum coke recarburizers, but the choice of petroleum coke recarburizers in steelmaking is generally roughly It can be divided into two types, one is graphitized petroleum coke recarburizer, and the other is calcined petroleum coke recarburizer. The carbon content of these two petroleum coke recarburizers is above 98.5%. The same is the sulfur content between the two types. The price of low-sulfur petroleum coke recarburizer is relatively expensive.
If the petroleum coke recarburizer for steelmaking is to get good results, the key is to pay attention to the content index when purchasing petroleum coke recarburizer! During the converter smelting of steelmaking, the petroleum coke recarburizer used for high-carbon steel should contain less impurities, and the petroleum coke recarburizer required for top-blowing steelmaking should contain high fixed carbon and volatile content. The content of impurities such as sulfur, phosphorus and nitrogen should be low. As for the appearance, the petroleum coke recarburizer used in steelmaking should be kept dry and the particle size should be uniform and moderate.
Our low-sulfur and low-nitrogen Graphitized Petroleum Coke is made of calcined petroleum coke which is raw material, going through fully continuous graphitization process under the high temperature of minimum 2600℃ . Through crushing, screening and classification, we supply different particle size between 0-50mm at the customers' request. As the preferred material for high-end customers in the casting industry, "XINTAN" carbon raiser has excellent characteristics of high carbon content, good absorption rate and stable quality
