What is the difference between graphite recarburizer and coal recarburizer

The first is that the raw materials are different. The graphite recarburizer is made from natural graphite after screening and processing, and the coal recarburizer is made from anthracite calcining;
Second, the characteristics are different. Graphite recarburizers have low sulfur, low nitrogen and low phosphorus, high temperature resistance, good conductivity, etc. These are the advantages that coal-based recarburizers do not exist;
Third, the absorption rate is different. The absorption rate of graphite recarburizer is above 90%, which is why the graphite recarburizer with reduced fixed carbon content (75%) can also meet the requirements of use;
Fourth, the price of graphite recarburizer is relatively high, but the comprehensive use cost is much lower.
