Efficient composite deoxidizer: It is suitable for various forms of steel deoxidization, especially for converter steel deoxidization. The compound deoxidizer has strong deoxidation and desulphurization effect, can improve the flow performance of molten steel well, and solve the problem of nozzle nodding. Reduce the gas in steel, reduce the inclusion of liquid steel.
The main principle is that the calcium in the high efficiency composite deoxidizer can make the oxide in the molten steel become low melting point and easy to float deoxidation products, purify the liquid steel, in addition, the use of this product is simple, improve the alloy addition rate, can reduce the alloy consumption, reduce the cost of tons of steel raw materials. And improve product quality, its economic and social benefits are remarkable. When used in electric furnace as reduction deoxidation, it can replace silicon powder, silicon, aluminum and barium, which greatly reduces the cost of steelmaking.
Like our commonly used iron silicon, metal silicon, ferro manganese, barium silicon, silicon carbon alloy and silicon slag, they are all composite deoxidizers. Compound deoxidizer is one of the common deoxidizers. Compared with the ordinary deoxidizer, the compound deoxidizer is better, which refers to the deoxidizer containing two or more deoxidizing elements.
Characteristics and functions of compound deoxidizer.
What are the effects of different types of compound deoxidizers:
Silica-aluminum-iron composite deoxidizer: silica-aluminum-iron composite deoxidizer is a variety used more in some large iron and steel enterprises, and it is also a composite deoxidizer used earlier, which can partially replace pure aluminum. For the deoxidation effect, it should be appropriate to add a little more, which has an adverse effect on the quality of steel;
Silica-barium aluminum-iron composite deoxidizer: The deoxidizer is also another variety used more by some large enterprises. Barium has a strong affinity with oxygen and sulfur, and has a good deoxidation effect. The application results show that the deoxidizing products are easy to float, the inclusions are changed, the liquid steel is purified and the properties of the steel are improved by using the compound deoxidizer containing barium.
New composite deoxidizer: In electric arc furnace, open furnace and converter, including die casting and continuous casting process, sedimentation method and wire feeding method, after deoxidation test under large production conditions, it is found that the new composite deoxidizer formula is new and the effect is good.
The use of alloy products:
