1997年1号高炉产铁84451t,利用系数达2.413t/m~3·d,入炉焦比为633kg/t;比2号高炉多产铁2233t。利用系数提高了0.065t/m~3·d,焦比降低了2kg/t,增产节焦效果好。主要原因是:2号高炉5月份开始护炉,影响了铁产量和冶炼强度,其中冶炼强度比1号高炉低了0.036t/m~3·d,休风率高了0.11%。此次护炉达到了预期效果。两座高炉焦比完成得不理想,主要原因是:原燃料质量波动较大,导致高炉炉况不
In 1997 No. 1 blast furnace produced 84451t of iron, the utilization coefficient reached 2.413t / m ~ 3 · d, into the furnace coke ratio of 633kg / t; than No. 2 blast furnace prolific iron 2233t. The coefficient of utilization increased by 0.065t / m ~ 3 · d, the coke ratio decreased by 2kg / t, and the effect of increasing sectional coke production was good. The main reason is that No.2 blast furnace started to protect the furnace in May, which affected the iron production and smelting strength. The smelting strength was 0.036t / m ~ 3 · d lower than No.1 blast furnace, and the windbreak rate was 0.11% higher. The protector to achieve the desired effect. The two blast furnace coke completed less than satisfactory, mainly due to: fluctuations in the quality of the original fuel, resulting in blast furnace condition is not
