| 摘 要： | 在实验室模拟研究了结晶器内酸性保护渣的传热情况。结果表明：增加保护渣的粘度、提高保护渣的凝固温度，结晶器与坯壳之间渣膜的传热系数和热流密度都减小而热阻增加，通过调整保护渣的性能，可调节渣膜的传热系数，使其适应连铸坯生产的要求。

| Abstract: | The heat transfer of mold flux in mold was investigated in laboratory. It was shown that with the increase in viscosity and solidification temperature of mold flux, the thermal conductivity and the heat flux density of flux were reduced, and the thermal resistance was increased. The thermal conductivity of mold flux between the mold and the solidified shell can be adjusted by changing the properties of mold flux. |

| Keywords: | continuous casting mold flux thermal conductivity |
