What is a carburant?
In the smelting process of iron and steel products, due to factors such as smelting time, holding time, and long overheating time, the smelting loss of carbon elements in molten steel increases, resulting in a decrease in the carbon content in molten iron. As a result, the carbon content in the molten iron cannot reach the expected theoretical value of refining. Carbon-containing substances added to make up for the carbon content lost during steel smelting are called carburizers.
Graphite recarburizer refers to the change of molecular structure of carbon products through high temperature or other methods, and regular arrangement. This molecular arrangement, the molecular distance of carbon is wider, which is more conducive to decomposition in molten iron or steel liquid. nucleation. Generally speaking, there are two ways of graphite recarburizers on the market, one is the waste cutting of graphite electrodes, and the other is the graphitization product of petroleum coke at 3000 degrees.
Main application scope: steelmaking, casting, wear-resistant materials, carbon paste and carbon products, etc.
Semi-graphitized recarburizer: carbon>98.5%, sulfur<0.3%, ash/volatile matter<0.7%, moisture<0.5%, nitrogen<500ppm (different particle sizes can be produced according to customer needs)
