Anthracite carburizer is an additive used for tempering steel. The product quality is regulated by the fixed carbon composition, which can be divided into special grade (Fc ≥ 95%), grade 1 (Fc ≥ 94%), grade 2 (Fc ≥ 93%), and grade 3 (Fc ≥ 90%).
Anthracite carburant, generally with ash content less than 7% and sulfur content less than 0.3%, is a high-quality carburant that can only be processed from high-quality Anthracite, mainly as follows:
1. High quality Anthracite from Ningxia can produce high quality steelmaking carburizer by reducing ash content and heat treatment process.
2. The particle size of coal based carburetor is usually 1-8mm, and its actual effect can be compared with that of Petroleum coke carburetor.
3. The selection of coal based carburetor has no effect on the composition of steel, the total amount of impurities, the degree of crystallization, and the Strength of materials properties of crystal structure, and the quality of steel reaches the standard rate of 100%.
4. The application of coal based carbon additive instead of Petroleum coke carbon additive for iron making and carbon increase can reduce the cost of enterprises and improve the economic benefits of companies.
5. The sulfur content in blue charcoal undergoes a different transformation with the temperature of the thermal decomposition working environment, and the effect is not significant; The heat dissipation of orchid charcoal is much higher than that of raw coal, and its sulfur content is also low. It has the meaning of using thermal decomposition desulfurization technology to produce clean fuel.
The electrical conductivity and carbon dioxide chemical activity of calcined blue charcoal are not related to the temperature of the thermal decomposition environment; The coal with high degree of metamorphism has a lower conductivity value of blue carbon and a higher activation energy of CO2 chemical change. The conductivity and chemical change activity of semicarbon are specifically related to the degree of Condensation reaction and graphitization level of aromatics in its structure.
The characteristics of high-quality carburetors include:
1. The particle size is moderate, the porosity is high, and the adsorption speed is relatively fast.
2. The ingredients are pure, with high carbon content, low sulfur content, and extremely low harmful components, with high absorption rate.
3. The graphite crystal structure of the product is good, improving the nucleation ability of the original iron liquid. Increase the number of graphite balls in ductile iron during inoculation, and increase graphite crystal nuclei in electric furnace molten iron. Fine differentiation, uniform degree of distribution The dispersion of high-purity graphite in castings.
4. Excellent and relatively stable characteristics.
