Made from selecting material of high quality, melting the material in electric furnace, cooling, crashing into different sizes. This product can be divided into following types: CaO-Al2O3, CaO-SiO2-Al2O3-MgO and CaO-Al2O3-BaO-CaF2.We can also adjust product\'s composition according to customers' requirement.
Principle: 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 its low density and can also have warm - keeping function.

Character and uses:
For being produced by melting method, it possesses more merits than other kinds of clinkers:
1. The composition is consistent
2. The low melting point, quick melting speed, good liquidity and good lubrication make desulphurization more efficiently.
3. There is no need to melt clinker, so the smelting time is much shorter.
4. The product is in the form of block or grain so that dust pollution in smelting can be greatly reduced.
5. It is mainly used for desulphurization and temperature preservation in high-quality steel-making.
Size:
The common size is 1-30mm.Other sizes can be supplied according to customer’s requirements.
Packing:
1000kg in coated plastic woven bag or at customer\’s option.
