超低氧钢熔炼过程中炉衬与钢液的相互作用

Interaction between Molten Steel and Lining Material in Refining of Extra-low Oxygen Steel

研究高温下耐火材料的相对稳定性及在真空熔炼超低氧钢过程中炉衬材料向钢液供氧的热力学条件和动力学规律。结果表明,在真空感应熔炼过程中,通过透气砖向熔池吹氩,可以实现在较低的真空度下熔炼超低氧钢,以及有效去除钢中的氧化物夹杂物颗粒。

The relative stability of refractory materials at high temperature is discussed,and so are the thermodynamic conditions and kinetics of oxygen contamination of molten steel from lining material during the refining of extra-low oxygen steel under vacuum.It is shown that,for the refining of extra-low oxygen steel under low vacuum,blowing argon through porous plug into molten steel can effectively remove oxide inclusions from molten steel.
