酒钢竖炉采用“低风温、大风量”操作的实践

Practice of Low Temperature-Large Wind Volume Roasting Schedule in JISCO

酒钢1#、2#球团竖炉由于受原料条件的限制,国内其他厂所采用的高温焙烧法不适宜该厂的生产需要。经过两年的生产实践及探索,提出了"低风温、大风量"操作法,该操作法的应用使利用系数由2006年的7.3 t/(m2.h)提高到2007年的8.2 t/(m2.h),作业率也由2006年的89.26%提高到2007年的96.7%,创下了国内同等原料条件下竖炉生产的较好水平。

Since the production operation of 1^# , 2^# shaft furnaces in JISCO are restricted by raw material conditions, so the high temperature roasting schedule which was widely used in other shaft furnace plants is not suitable. In this paper, a low temperature-large wind volume roasting schedule was proposed, and after this roasting schedule put into practice, the productivity of shaft furnaces was increased from 7.3 t/ （m^2·h） in 2006 to 8.2 t/ （m^2·h） in 2007, and the operating rate was also increased from 89.26% to 96.7%.
