钢液用Fe－Si、Ba－Ca－Si作发热剂的实验研究

EXPERIMENTAL STUDY ON MOLTEN STEEL TREATED WITH Fe-Si AND Ba-Ca-Si HEATING AGENTS

采用Ｆｅ－Ｓｉ、Ｂａ－Ｃａ－Ｓｉ作发热剂，对钢液进行了化学升热法的实验研究。主要测定了升温速度、升温值和热效率，讨论了发热剂加入量过剩指数、氧流量、供氩强度和枪位对升温效果的影响。

The paper studies the speed and the range of raising temperature of molten steel as well as the heat efficiecy with chemical heating method, using Fe-Si and Ba-Ca-Si alloy as heating agents. The factors affective the speed and the range of raising temperature are researched,
