Calcined Anthracite coal is produced when Anthracite is calcined under the temperature of 1240 ℃ in vertical shaft furnaces, mainly used in electric steel ovens, water filtering, rust removal in shipbuilding and production of carbon material.
Need for high-quality calcined coal carbonization agents? What are the characteristics of high-quality calcined coal carbonization agents?
1. The particle size is moderate, the porosity is high, and the adsorption rate is relatively fast.
2. The ingredients are pure, with high carbon content, low sulfur content, minimal harmful components, and high absorption rate.
3. The graphite crystal structure of the product is good, which enhances the nucleation ability of the original iron liquid. Add the number of ductile iron graphite balls to the nurturing process, and add high-purity graphite crystal nuclei to the electric furnace molten iron. The dispersion of finely differentiated and uniformly distributed high-purity graphite in castings.
4. Excellent characteristics and relatively stable.
Carbon additives have two main uses, namely as fuel and additives. When used as a carbon additive in steelmaking and casting, the carbon fixation rate can reach over 95%.
The smokeless coal carbonization agent uses smokeless coal as raw material and is calcined at high temperatures above 2000 ℃ in a direct current electric calcination furnace. It effectively eliminates moisture and volatile matter in smokeless coal, improves its density and conductivity, enhances its mechanical strength and oxidation resistance, and has good characteristics such as low ash content, low electrical resistivity, low carbon, and high density. It is an excellent raw material for manufacturing high-quality carbon products and is used as a carbon additive or fuel in the steel industry.
