高炉开炉操作是否正确,对一代高炉的正常操作和高炉炉龄有着重大影响。因此,探讨开炉冶炼的规律,做好开炉工作就十分必要。一、开炉冶炼过程的主要矛盾及其转化高炉冶炼只有在炉缸下部(即上渣口以下)热量充足、温度够高的情况下,才能最后完成和多快好省地进行。开炉前期炉缸下部温度(以下简称T_下~＇)远低于正常,这时L_s较低和[S]％、
The blast furnace operation is correct, the normal operation of a generation of blast furnace and blast furnace has a significant impact. Therefore, to explore the law of open smelting, do a good job in the furnace is necessary. First, the main contradictions and their conversion process blast furnace smelting blast furnace smelting only in the lower part of the hearth (ie, slag below the mouth) sufficient heat, the temperature is high enough to be the last to complete and more quickly and economically. The temperature of the lower part of the hearth of the pre-blast furnace (hereinafter referred to as T_down ~ ’) is much lower than normal, and the L_s is lower and [S]%,
