Abstract: Based on the principle of the continuous smelting magnesium technology, the article analyses the physical parameters of the heat-transfer medium in the reduction pot in the continuous silicothermic process for magnesium production. Moreover, in this paper, the feature of heat-transfer process and the temperature field of reduction pot are studied by the computer simulation method. The results show that the intestine reduction temperature can reach 1250˚C and that the reduction efficiency is high. After the end of the reaction, we can get the condensed magnesium in the magnesium crystallizer. The content of magnesium is 95.23%.
