Molten steel refining is an important process in steelmaking, and the molten steel refining agent is an important factor in determining the effect of molten steel refining. Traditional molten steel refining agents are made of lime and bauxite in a certain proportion. This method has obvious disadvantages, which not only affects the slag formation speed, refining time and energy consumption of the refining agent, but also affects the transportation A certain amount of dust pollution is also generated during the production process.
The electro-melting refining flux produced by our company overcomes the shortcomings of the above-mentioned processes and raw materials. Through the pre-melting process, lime and bauxite are generated in advance. Calcium aluminate (12CaO•7Al2O3 ) is produced. This method can quickly form slag and shorten the smelting time for normal refining. It is beneficial to reduce inclusions in molten steel . especially Alumina inclusions make premelt refining agent an ideal charge for molten steel refining.
The pre-melted refining agent (slag) produced by our company meets the emission requirements of steel plants such as low dust and low sulfur, and can achieve deoxidation, desulfurization, and removal of molten steel during refining. Mixing and other refining effects help the transformation and green development of environmentally friendly steelmaking . In the process of ladle refining, the selection of refining slag is related to the operating system. to the key factors of desulfurization, deoxidation and inclusion removal.
Electrofusion refining slag has the characteristics of uniform composition, stable performance, no water absorption during storage, less dust, and little environmental pollution. Has strong adsorption The ability of non-metallic inclusions in steel and the high comprehensive desulfurization rate have a significant effect on purifying molten steel.
. Product Description
Electrofusion refining slag refers to mixing the raw materials according to a certain proportion and particle size, and then using high temperature in special equipment to melt the slag at a temperature higher than the melting point of the slag system. The raw materials are melted into a liquid state, cooled and crushed before being used as refining slag in the steelmaking process.
. Features
1. The mineral composition of this product is calcium aluminate, which has a low melting point and can quickly form slagging and efficiently remove inclusions and desulfurization from molten steel.
2. This product has uniform chemical composition and no component segregation, which ensures the rapid formation of refining slag and greatly shortens the refining time. 3. This product has a compact structure, does not absorb water, is easy to store and transport, does not pulverize or volatilize, and can significantly reduce dust pollution in steel plants.
