Abstract
The article is devoted to the study of the peculiarities of microalloying processes and steel modification with technogenetics and natural materials. The authors have researched metallurgical properties of barium-strontium natural modifiers and have estimated its influence on the melting temperature of the forming reducing slag. The received data have shown that the usage of the modifier in the conditions of industrial production is highly producible. Using the software package TERRA the assessment of barium and strontium reducibility with silicon and aluminum from their oxides has been fulfilled, as well as the possible mechanisms of a modifying influence of barium and strontium on the quality of metal has been studied. The possibilities of using vanadic converter slag have been shown for steel microalloying with vanadium. Efficiency assessment of vanadium reduction with carbon of the molten steel has been done. The authors have given the data of industrial testing of the studied materials, which have shown very good convergence with the theoretical calculations and conclusions. The recommendations to optimize the technology of mictoalloying and modification have been given. The use of the researched materials allows improving technical and economic indices of steel production process and significantly increases the quality of the end production. The conclusions on the perspective significant widening of using the technogenetics and natural materials have been done.
