1956年9、10月,鞍钢炼铁厂在一些高炉上开始实行了降低湿份、提高乾风温度、降低焦比的操作方针后,A、?、B、?、?、E高炉乾风温度均有所提高(表1),其中以A、?、?、E高炉最为显著,且提高较为顺行。B、?高炉在降低湿份的同时,在一定程度上引起高炉不顺,因而,乾风温度提高较少。山于各高炉冶炼条件各不相同,而且冶炼操作在一些高炉较为混乱,只能就各高炉情况作出初步的探讨。一、提高乾风温度的效果
In September and October 1956, Anshan Iron and Steel Co., Ltd. began to implement the operational guidelines of lowering the wet temperature, increasing the dry air temperature and reducing the coke ratio on some blast furnaces. (Table 1), of which A,?,?, E blast furnace the most significant, and to improve more smoothly. B, the blast furnace to reduce the wet at the same time, to a certain extent caused the blast furnace is not smooth, therefore, dry air temperature increase less. Mountain blast furnace smelting conditions vary, and the smelting operation in some blast furnace is more confusion, only to make a preliminary discussion of the blast furnace conditions. First, to improve the effect of dry air temperature
