High Carbon Recarburizer

High carbon recarburizer can more effectively provide carbon elements for molten steel and molten iron, so it is favored by steel mills and foundries.

High carbon recarburizers are often expensive, but according to process requirements, some high carbon recarburizers are not suitable for use, especially in the casting process, castings often require low sulfur and low nitrogen high carbon recarburizers. Such as coal carburizer with high carbon content, it is difficult to meet the requirements of low sulfur and nitrogen.

High carbon recarburizer does not mean that it has a good absorption rate. The absorption rate determines whether it can be fully utilized during use. If the absorption rate is low, even the high carbon recarburizer cannot achieve good results.

Generally, the method to reduce the sulfur and nitrogen in the high carbon recarburizer is generally to use the calcination process. To increase the absorption rate, it is necessary to use the high carbon recarburizer after graphitization.

For example, graphite recarburizer is currently a high carbon recarburizer with low sulfur, low nitrogen and good absorption rate. After 2500 3500 high temperature graphite treatment process, its carbon content can be as high as 98% or more,is the main raw material for the production of high quality steel cast iron.
