Evaluation of the Use of Complex Mineral Concentrate as a Modifier Steel

Increasing customer demands for quality of the resulting metal, and in the first place, the impurities, metallurgists dictate need to develop new and improved technologies. Thus, a significant reduction in metal losses can be achieved by developing new complex alloy steels, special purpose, improving technology of their production and developing new technology of smelting to improve the physical, mechanical, foundry and operational characteristics by influencing the structure of the steel by modifying the liquid melt, change more favorable morphology of nonmetallic inclusions. For complex-alloyed steels expensive and scarce alloying elements Ti, Nb, Zr, etc., are used, which are inaccessible to conventional structural steels. In this regard, the paper also presents the results of applying of innovative modifiers containing alloying elements (Ti, Nb, Zr, etc.) based on mineral concentrates in the Tomsk region. (paper)
