Made from selecting material of high quality, calcining the material in rotary kiln, cooling, crashing into different sizes and can be used in refining ladle to get rid of sulphur and other useless component from steel-liquid. Specification: Chemical composition% CaO 48-50 Al2O3 37-41 SiO2 4-6 TiO2 2.5 Fe2O3 2.5 MgO 1.5 CaF2 - Other varieties are also provided, and we can adjust the product\\\' composition according to customer's requirement. Principle: Add deslag substance--Calcium Aluminate into the molten steel in LF furnace. Quantity is about 1.5% of the molten steel in LF, namely, one ton molten steel needs Calcium Aluminate 10- 15Kg. Density of molten steel is higher than Calcium Aluminate and the ratio is about 7.8:3.5. In the deslag course, Argon was pumped in LF furnace from the bottom, it drives the deslag reagent to mix with the molten steel completely. Then the reagent adsorbs sulphur substance completely. Dregs will suspend on the surface of molten steel due to it s low density and can also have warm-keeping function. Character and uses: 1. Anti-moist, Anti-powder and not going bad in storage and transportation. 2. Its components of mineral are basically same as the Fused Type. 3. Low melting point. It can be easily melted in steel-liquid to get rid of sulphur. 4. Flow of steel slag can be kept well. Size: 1-30mm Packing: 1000kg in coated plastic woven bag or at customer's option.
