摘要

如果铝热剂混合物中含有氯化钠和氯化钾等氯化成分,则可能对放热反应行为产生有效影响。它们在铝热剂混合物中的含量分别低于7%和7.25%,可以通过增加获得的金属熔体的体积来提高铝热过程的效率,通过降低放热过程强度来减少钢结构中的一些非金属夹杂物,从而控制生产钢的物理机械性能。

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

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.
