Composite deoxidiser is a kind of high efficient steelmaking auxiliary material with the following characteristics:
1. High independent deoxidation efficiency and fast speed
Composite deoxidiser can be added to steel water in a certain proportion to form active and stable white slag rapidly, and can meet the deoxidation requirements without adding other deoxidising alloys, such as silica-aluminium-iron, silica-calcium-barium or silica-aluminium-barium.
2. Improve alloy yield, adsorption of inclusions, purify steel
Composite deoxidiser has high deoxidation efficiency, not only has excellent deoxidation, desulphurisation function, but also can make the oxide inclusions spherical, stable adsorption in the slag, to purify the steel.
3. Wide range of steel types
Composite deoxidiser is not only suitable for unrefined plain carbon steel, but also adapted to refined low alloy steel, medium and high carbon steel and other steel types. At the same time, it can shorten the refining time and improve the hit rate and recovery rate of alloy. The dosage is generally 1.0-1.5 kg/tonne steel, and the slag is thin, not staining the package wall, easy to pour slag.
4. Economic and efficient
Composite deoxidiser has low price, convenient transportation, no moisture absorption, no pulverisation, safe use and no hidden danger of stock.
