Silicon carbide ball is a new kind of compound deoxidizer, its products are fast deoxidization, slag early, reducing atmosphere thick, and the advantages of abundant foam, it can replace traditional more expensive deoxidizer ferrosilicon powder and powders, suitable for deoxidization, alloy steel and special steel smelting, silicon carbide ball element can effectively improve absorption rate, also has the effect that increasing carbon, instead of part of the carburant, greatly reduces the cost of steelmaking.

With silicon carbide balls can make molten steel quality is stable, and has fine grains, removal of harmful impurities in molten steel, after using molten steel casting temperature is high, the slab of good quality and low cost per unit.

Silicon carbide ball in recent years, the development trend of rising gradually, in the steel industry development rapidly, especially has a tendency to replace silicon carbide particles, gradually become indispensable to the steel furnace charge.

Select and use requirement: the size of silicon carbide ball for large steel mills, ladle is relatively mostly: 80 tons, 100 tons, 100 tons of specifications, such as smelting time long long reaction time.5 to 6 cm large materials of silicon carbide ball weight and the process of has certain advantages, and in the liquid steel reaction and dissolution effect is good. And 3 to 10 mm silicon carbide small pieces, to more suitable for small medium frequency furnace, cupola, etc. Dissolution time fast, good absorption, and shall not affect the steelmaking time, also reduces the production cost.
