摘　　要：稀土氧化物对中间包覆盖剂和实验室合成渣粘度的影响的试验表明 ,当稀土氧化物含量不大于 10 %时 ,具有降低覆盖剂高温粘度的功能 ,当稀土氧化物含量接近 2 0 %时 。The test results with regard to the effect of rare earth oxides on viscosity of commercial shielding flux for tundish and laboratory synthetic flux showed that as the rare earth oxides content was less than 10%, the viscosity of shielding flux at high temperature decreased, and while the rare earth oxides content was up to 20%, the viscosity of shielding flux increased obviously.

关 键 词：稀土氧化物 中间包 覆盖剂 粘度 炼钢 连铸
