本文采用现场浸棒法与实验室中频感应炉浸棒法对Al和Si含量不同的Al_2O_3-C材料以及ZrO_2-C材料进行了抗保护渣侵蚀试验。结果表明,Al和Si的加入量之比为1时,Al_2O_3-C材料抗保护渣侵蚀性最好,但还不及ZrO_2-C材料。
Simulative study on corrosion of Al_2O_3-C refractories by mold coverflux has been carried out by means of immersion method. The results show that therefractory exhibits best resistance to the flux while the ratio of additive Al and Si isapproximatly equal to one.
