摘    要：伯利恒化学升温工艺是一种成本相对较低的在钢水罐车上升高钢水温度的方法。该工艺利用加入金属铝和吹氧的方式,形成放热反应。在喂入铝线或加入铝块的同时,通过插到钢水中消耗式氧枪,向钢水熔池内吹氧。介绍了设备组成、化学升温工艺、处理周期模型,以及具有竞争性的主要特点。

Abstract: The Bethlehem Process of chemical reheating is a relatively inexpensive method for increasing the temperature of molten steel contained in the transfer ladle.The process uses oxygen and aluminum to generate an exothermic reaction.The oxygen is injected into the steel bath by a submerged disposable lance,while the aluminum is introduced in the form of wire or nuggets.The equipment components,process of chemical reheating,treatment cycle modeling,and competitive advantages are introduced.
