How to choose Carbon Additive

1.Recarburizers treated with high temperature graphitization should be used as much as possible

High-quality recarburizers have the following advantages: high absorption rate, fast dissolution rate, reduced energy consumption, can effectively increase the core of the molten iron core and improve metallurgical quality.


2.Use recarburizers with lower impurity elements such as sulfur and nitrogen

When the iron liquid nitrogen content is higher than the equilibrium concentration, crack-type nitrogen pores will appear.When the impurities are high, the tendency of casting chips to increase.


3.Choose the appropriate recarburizer particle size according to different calcining furnace body size

The small particle size recarburizer has the characteristics of fast dissolution rate and high loss rate.
