Product Description:
Electrofused calcium aluminate( Pre-melt Calcium-Aluminate) , also known as pre melted refined slag or pre melted aluminum calcium slag, has been maturely applied for several years in developed countries such as South Korea, Japan, Europe and America. In recent years, it has received attention in China and has become a direction for industry development. Xingshi New Material Technology Co., Ltd. adopts independent research and development technology, which uses hazardous waste aluminum ash as raw material to produce calcium aluminate. At present, it is at the forefront of technological level in the domestic industry. The company is also committed to the technological development of hazardous waste disposal in the entire aluminum industry chain, and has made considerable progress so far.
The electrically melted calcium aluminate produced by the company has a uniform chemical composition, low melting point, fast melting speed, and can shorten the smelting time; Not eroding the furnace lining and ladle; Dense structure, non absorbent, easy to store and transport in warehouses; Due to its stable phase and fast slag formation, it can reduce dust pollution to steel plants and comprehensively stabilize the refining process; Free from impurities such as hydrogen and atmospheric carbon, it is beneficial for improving the quality of steel.
Xingshi New Material Technology Co., Ltd. has a production line with an annual output of 30000 tons of calcium aluminate, all of which use self-developed technology. Calcium aluminate is an inorganic compound produced by smelting calcium oxide and aluminum oxide at high temperatures. Due to its high hardness and melting point, it is mainly used in the metallurgical industry and as a water purification agent. The annual processing of hazardous waste aluminum ash (hazardous waste code 321-024-48321-026-48) is 15000 tons, and the production technology level is at the forefront of the same industry in China, with products facing the world. The reliability, practicality, and stability of product technology have all reached a high level in the industry.
Application:
Calcium aluminate refining slag is mainly used for steel liquid purification and process optimization in steel smelting, with specific applications including:
Deoxygenation and desulfurization
The refined slag of calcium aluminate contains a large amount of active calcium oxide (CaO), which can quickly react with oxygen (O) and sulfur (S) in the molten steel, significantly reducing the oxygen and sulfur content in the steel. For example, in the case of an original sulfur content of 0.027%, the desulfurization rate can reach over 80%, and the endpoint sulfur can be reduced to below 0.005%.
Its main component is 12CaO · 7Al2O3, which can quickly form low melting point products and efficiently remove impurities.
Purification of molten steel
By adsorbing non-metallic inclusions (such as oxides and sulfides) in steel, the purity of molten steel is improved and the performance of steel is enhanced.
Suitable for the refining process of various steel grades such as ordinary carbon steel, high carbon steel, and alloy steel.
Optimize refining process
Shorten refining time: Fast slagging speed, reduce the time consumption of slagging process, and improve production efficiency.
Reduce energy consumption:
Reduce oxygenation and electricity consumption during smelting, for example, the application effect is significant in LF furnaces, electric furnaces, and converters.
Improve slag flowability:
Adjust the viscosity of refined slag and enhance the separation effect of steel slag.
Environmental Protection and Stability
The product does not absorb water, does not pulverize, is easy to store and transport, reduces dust pollution during the production process, and meets environmental protection requirements.
The composition is uniform and stable, and the chemical activity is maintained for a long time, avoiding the impact of traditional slag performance fluctuations on production.
Through the above functions, calcium aluminate refining slag has become a key auxiliary material for improving steel quality, reducing costs, and achieving green production in the modern steel industry.
