Silicon carbide deoxidizer can improve the strength to enhance toughness, and has a rapid deoxidation into slag early, the reduction atmosphere is thick effectively improve the recovery rate of the elements, greatly reducing smelting costs, so that the quality of iron is stable, delaying the time of iron conception recession of a new material with high technological content.
Silicon Carbide Deoxidizer Features
Silicon carbide deoxidizer is used in the reduction period of electric furnace steelmaking deoxidizing materials, it has the following characteristics.
- Oxygen reaction than ferrosilicon powder, carbon powder, calcium carbide block can shorten the reduction time, reduce power consumption and improve labor productivity.
- Silicon carbide deoxidizer decomposition and oxidation at high temperatures is an exothermic reaction process, the positive pressure in the furnace is strong, can ensure that deoxidation, Beibei sulfur to provide the necessary conditions to reduce the sulfur content.
- Due to the reduction period is shortened, reduce the opportunity of steel in the later stages of gas absorption, thus ensuring the quality of the molten steel.
- Reduce the amount of quicklime, fluorite powder added to reduce costs, reduce the concentration of harmful gases and soot pollution of the environment, conducive to the improvement of operating conditions.
- Foam slag rich and active, while bubble wrapped arc yellow, reduce arc radiation, thus improving the life of the furnace lining, furnace cover, reduce the time of hot stop furnace and the consumption of auxiliary materials.
Comprehensive above, resistant material silicon carbide deoxidizer for electric furnace steelmaking reducing agent, per ton of steel cost reduction of 5-13 yuan, electricity consumption reduced by 10-40 degrees.
Role and use
Silicon carbide deoxidizer is a novel high-performance composite deoxidizer, can replace the more expensive traditional deoxidizer ferrosilicon powder and alloy powder, suitable for general steel, alloy steel and special steel smelting deoxidation, silicon carbide deoxidizer has the advantages of rapid deoxidation, slagging early, reducing atmosphere, rich foam, etc., but also effectively improve the recovery rate of the elements, but also have a carbon increase, instead of part of the carbon enhancer, greatly reducing the steelmaking cost.
Silicon carbide as a steelmaking deoxidizer can make the quality of stable steel, and has a fine grain, remove the role of harmful impurities in the steel, the use of steel casting temperature is high, good quality cast billet, low unit cost.

Silicon Carbide Deoxidizer Effect
- Speed up the reaction speed, shorten the smelting time, and have the effect of desulfurization.
- The temperature is easy to adjust, reducing power consumption and improving the life of furnace lining and furnace cover.
- The dust is small, and the amount of fluorite is reduced, and the concentration of toxic gas fluorine is reduced, which is beneficial to environmental protection.
