Metallurgical CAC Calcined Anthracite Coal Smelting Slag Of Calcium Aluminate
Smelting slag of calcium aluminate Metallurgical Auxiliary Material CAC Calcined Anthracite Coal
Product introduction
Calcium aluminate refining slag is more and more favored by iron and steel industry because of its characteristics of uniform composition, low melting point, fast melting rate and short smelting time. The product is mainly used in iron and steel metallurgical furnace and furnace refining.
The electromelting calcium aluminate refining slag produced by our company is made of high quality lime powder and bauxite as the main raw materials, and is melted in the electric furnace according to a certain ratio, to produce products dominated by CaO and Al2O3. The calcium composition can react with oxygen and sulfur in steel to produce products with low melting point and easy to float, so as to achieve the purpose of purifying liquid steel. The product has the characteristics of less impurities, stable and uniform composition, etc., and has achieved good use effect in Anshan Iron and Steel Co., LTD., Shi Steel Co., LTD., Xing Steel Co., LTD., Handan Iron and Steel Co., LTD. The results show that the desulfurization rate can reach more than 80% under the condition that the original sulfur is 0.027%, the effect of point sulfur is 0.005%, and the desired goal is achieved.
Product features
1) Uniform composition, low melting point, fast melting speed, can shorten the smelting time;
2) The slag viscosity and flow are appropriate to promote the deoxidation and desulfurization reaction between slag and molten steel;
3) Fast desulfurization, some steel even required to reach very low sulfur (less than 0.0010%). The desulfurization effect is more than 60%, and the phosphorus recovery can be effectively inhibited.
4) Effective adsorption capacity of inclusions, a certain degree of deoxygenation and deoxygenation, can effectively adsorb floating inclusion and deoxygenation products, is conducive to tempering purification;
5) Effectively improve the protection effect of ladle lining. It is well known that slag has the greatest erosion effect on refractory materials. The reasonable control of slag can protect the lining of furnace.
6) Non-absorbent, easy to store and transport;
7) Due to uniform composition and fast slag formation, dust pollution in steel plants can be reduced;
8) Fluorine free, protect the ecological environment, do not erode furnace lining; Does not contain hydrogen, nitrogen, carbon and other impurities, is beneficial to improve the quality of steel.
9) adding less is conducive to electricity saving, less slag discharge is conducive to environmental protection.
