高炉出炉铁水含硅量[Si]一直被认为是衡量炉温(炉内渣铁温度)的标志。本试验表明,[Si]值不仅与炉内温度有关,而且还与炉子大小及冶炼条件和操作制度有关。当冶炼条件不同和操作制度变更时,若维持原渣铁温度,[Si]值必须相应改变,否则就会引起实际渣铁温度变化。同时[Si]值又是生铁质量指标。因此研究高炉内硅还原 Blast furnace baked silicon content of molten iron [Si] has been considered as a measure of furnace temperature (furnace slag temperature) signs. This test shows that the value of [Si] is not only related to the temperature in the furnace, but also to the size of the furnace, the conditions of smelting and the operating system. When the smelting conditions are different and the operating system is changed, the [Si] value must be changed accordingly if the original slag iron temperature is maintained, otherwise the actual slag iron temperature will be changed. At the same time [Si] value is the quality indicator of pig iron. Therefore, the study of silicon reduction in the blast furnace
