１前言现代炼钢离开喷吹惰性气体是不能想像的。喷吹气体的有铁水罐、转炉、电炉、二次精炼用大罐和中间包等。本报告将介绍大罐用供气砖的开发，并得出以下结论：按供气砖形状形成的气泡依赖于气体的流量和压力，其结果产生的反向浸蚀现象属于多孔型供气砖的特征，而且不...
1 INTRODUCTION Modern steelmaking can not imagine blowing off inert gas. Inflatable gas tank with iron, converter, electric furnace, secondary refining with large tundish and tundish. This report will introduce the development of large tank gas supply bricks and draw the following conclusions: Bubbles formed by the shape of gas supply bricks depend on the gas flow rate and pressure, and as a result, the reverse etching phenomenon belongs to porous gas supply bricks Feature, and not ...
