1, the refining slag selected excellent calcite and bauxite as the main material, in the rotary kiln after 1300℃ forging and burning;
2. Refining slag simplifies slag making process, no flame, no dust, * non-toxic, environmental protection;
3. The screened products are lumpy and granular, with uniform composition, fast melting speed and good flow and spread performance;
4. Quick slag formation can reduce dust pollution in steel works, shorten smelting time, improve production efficiency, reduce oxygen increase during smelting, and reduce power consumption during refining;
5, it has a strong deoxidization ability, in (Fe-SI SI-Mn) with the cooperation, can effectively remove the oxygen in the steel, and the slag can be a good adsorption of solid deoxidization products floating together. In addition, as the synthetic slag is strongly alkaline slag, it can be deoxidized and desulfurized at the same time. High alkalinity, high sulfur capacity, remarkable desulfurization effect, desulfurization rate reached more than 85%;
6. Adsorb aluminum and silicon oxides in steel, which is conducive to reducing non-metallic inclusions in steel and improving steel quality;
7. With or without fluorite, the furnace lining and ladle can be corroded lightly to reduce the consumption of ladle refractories and improve the age of ladle;
8. The curve function of the product's stability with time almost forms a straight line, avoiding many inadaptability phenomena brought by the wave and sawtooth curve function of medium and low grade products to metallurgical production;
9, no water absorption, no powder, no deterioration, easy to store and transport.
