With the continuous development of steelmaking technology, the quality of molten steel is improved and the production is clean. High purity molten steel is a new product produced by our factory, which is beneficial to the heat preservation of molten steel, prevents the oxidation of molten steel from contact with air, and can absorb AL, SI and S inclusions in molten steel, and ADAPTS to the current alkaline coating agent with high alkalinity to replace the pollution of carbonized rice husk, and the carburization of molten steel and the absorption of inclusions by acidic coating agent.
I, metallurgical action
1, heat insulation and prevent steel surface crust.
2, isolate the air and prevent the liquid oxygen of steel.
3. Absorb non-metallic inclusions in liquid steel.
II. Metallurgical properties
1, chemical composition %
CaO AL2O3 SiO2 R
18-33 <5 13-28 >1
2, melting temperature 1200℃-1450℃
3, melting speed 1450℃ greater than 20S
The coating agent can be produced according to the environment of different steel mills.
