High performance composite silicon carbide deoxidizer Refractory Materials

product introduction

Silicon carbide deoxidizer can improve the strength and toughness, and a rapid deoxidization into slag early, reducing atmosphere is strong effectively improve the recovery of elements, greatly reduce the cost of smelting, so that the quality of molten iron is stable, delay the breeding of molten iron recession time of a high content of science and technology of new materials.

Functions and characteristics:

Silicon carbide deoxidizer is a kind of novel high-performance compound deoxidizer, it can replace traditional more expensive deoxidizer ferrosilicon powder and powders, suitable for PuGang deoxidization, alloy steel and special steel smelting, stone silicon carbide deoxidizer has early deoxidization quickly, slag, reducing atmosphere thick and rich foam, it can effectively improve recovery of elements also have increased carbon effect, Replace part of recarburizer and greatly reduce the cost of steelmaking. Using silicon carbide as deoxidizer in steelmaking can keep the quality of molten steel stable, refine the grain and remove the harmful impurities in molten steel, and the casting temperature of molten steel is high, the quality of billet is good and the unit cost is low.

The physical and chemical indicators

Use the point

1. Melting period, oxidation period according to the operating procedures.

2. After the rarefied slag is formed, silicon carbide is added to reduce, and the amount of addition depends on the steel water quantity and furnace condition of the furnace.

3, use effect:

1) Accelerate the reaction speed, shorten the smelting time, and have the effect of desulfurization.

2) the temperature is easy to adjust, reduce power consumption, improve the life of furnace lining and furnace cover.

3) The dust is small, the dosage of fluorite is reduced, and the concentration of toxic gas fluorine is reduced, which is conducive to environmental protection.
