| 摘 要： | 试验研究了五元渣（/%:50~65CaF2,6~15CaO,18~30Al2O3,4~10SiO2,1~7MgO）的组元含量、熔渣温度（1330~1463℃）对表面张力的影响。结果表明,随熔渣温度升高,其表面张力下降,1463℃五元渣的表面张力为0.372~0.418 N/m。60CaF2-15CaO-6SiO2-18Al2O3-5MgO具有较低的表面张力（0.375 N/m）,较好的流动性和低粘度值。3 t电渣炉熔炼镍基合金Inconel 600和625的工业应用结果表明,电渣锭成分均匀,O]≤20×10-6,N]≤50×10-6,平均电耗从原ANF-6渣重熔的1933 kWh/t降至1 326 kWh/t。

| Abstract: | The effect of ingredient of pentary slag (/% : 50~65CaF2, 6 ~ 15CaO, 18 ~ 30Al2O3, 4 ~ 10SiO2, 1 ~ 7MgO) and melting slag temperature (1330-1463 ℃ ) on its surface tension has been studied. Results show that with increasing melting slag temperature, its surface tension decreases, and the surface tension of pentary slag at 1 463 ℃ is 0.372-0.418 N/m. The surface tension of slag 60CaF2-15CaO-6SiO2-18Al2O3-5MgO has lower surface tension (0.375 N/ m), better fluidity and lower viscosity value. The results of commercial production of nickel base alloys Inconel 600 and 625 by 3 t ESR unit show that the elements content in ESR ingot are uniform, the gas content O] ≤20×10-6 and N] ≤50×10-6, the average power consumption decreases to 1 326 kWh/t from original 1933 kWh/t by remelting with slag ANF-6. |
