研究了RH真空精炼炉浸渍管用刚玉尖晶石质浇注料的蚀损机理：熔渣及钢液通过浇注料表面缺陷渗入其内部,与浇注料发生反应生成低熔点化合物;炉温频繁的波动,导致浇注料内部应力过大,使其产生裂纹;在钢液及熔渣的冲刷作用下,造成浇注料剥落。还探讨了提高浸渍管用浇注料使用寿命的途径。

The wear mechanism of corundum spinel castable used for the snorkel of RH vacuum refining furnace is studied. The smelting slag and molten steel penetrate into the inside of the castable through its surface defect and they react with castable to form low melting point compound. The temperature of the furnace fluctuates frequently to cause the generations of extra stress and cracks in castable. Under the scouring action of slag and molten steel, the castable is peeled off. And the ways for improving the service life of the castable for the snorkel are discussed.
