The Influence of Alkali Metal Chlorides on the Manufacturing Process and Steel Properties in Aluminothermic Reduction of Iron

Abstract

The effective influence on exothermic reaction behavior is possible if the thermite mixture contains chlorinated components such as NaCl and KCl. Their content in the thermite mixture less than 7% and 7.25%, respectively, permits one to improve the efficiency of the aluminothermic process by increasing in the bulk of obtained metal melt, to decrease a number of nonmetallic inclusions is steel structure owing to the reduction of exothermic process intensity, to control the physical-mechanical properties of the produced steel.
