Finer compound deoxidizer
Finer compound deoxidizer This product is traditional silicon powder, calcium carbide, silicon powder, silicon carbide substitute, its deoxidization reaction fast, white slag formation fast, shortened (refining) reduction time and reduce the material consumption, to reduce the pollution of the environment, improve working conditions. This product has strong ability of deoxidizing and desulfurizing, can change steel inclusions in the distribution, fine grains, improve the recovery of alloy, improve the mechanical properties of the steel, improve the quality of steel products, to improve the comprehensive economic benefit of electric furnace has an important role. Use requirement: (1) melt period, oxidation period according to the operating rules; (2) the thin slag formation, join this product, depending on how many of the molten steel join quantity and furnace condition and decide, points 2-3 batch of join of each interval 5-7 minutes, keep furnace of vital qi and reducing gas pressure, and the amount of more than 3.5 kg/ton to join. Use effect: (1) into white slag speed, shorten the smelting of time, the colleague desulfurization effect is good. (2) reduce power consumption, increase furnace lining, furnace cover life. (3) reduce the dosage of fluorite, poisonous gas "fluorine" concentration lower, be helpful for environmental protection. (4) can reduce the limitation steel tendency. For aluminum and nitrogen can produce stable AlN can prevent the formation of iron nitride and separation, can greatly reduce steel of aging tendentiousness. (5) the steel refining grain. Because of alcan deoxidization, in steel small scattered AlN generated and Al2O3. Particles as crystal core, make the grain refinement, in steel heated, the AlN and Al2O3 particles can prevent austenitic grain to grow up, get fine grain strong steel, so as to improve the yield degrees and just impact capricious. 6 and FeS transamination aluminum aluminum sulfide, reduce sulfide in the segregation of steel, so as to increase the steel under high temperature of plastic.
