摘要:

随着连铸和炉外精炼技术的发展,炉外钢水精炼处理主要在钢包中进行。这要求钢包内衬用耐火材料具有易于施工的特点,可达到优良的冶金效果。镁钙系耐火材料能满足这些要求,对洁净钢的冶炼非常有利,但由于镁钙系耐火材料易水化的特点限制了其应用。本课题通过实验,研究开发出性能优质的镁钙系耐火材料,尤其是填补了1 900℃以上超高温阶段国内外对镁钙质耐火材料研究的空白。

Abstract:

With development of continuous casting and secondary refining,the out-of-furnace refining treatments mainly proceed in steel ladle.The refractories for ladle lining are easy to constructed and have excellent metallurgical effects.MgO-CaO refractories can meet the above-mentioned requirements,and they are beneficial for clean steel production,but the applications for MgO-CaO refractories are limited by the hydration characteristics.The high quality MgO-CaO refractories fill the blank of ultra-high temperature researches especially above 1 900℃.
