目前,国内许多255m~3高炉贮矿槽槽下供料系统已经进行了技术改造,将原有的称量车改为带式输送机供料。杭钢、马钢二铁厂4号高炉还将烧结矿和球团矿在槽下再次进行筛分,并采用固定称量漏斗分散称量,对称量值进行误差补正。马钢一铁厂等还使用了焦炭中子测水进行焦炭水分补正。这些技术措施取得了较高的经济效益。仅烧结矿槽下过筛,每减少入炉烧结矿中小于5mm的粉末10%,就可降低焦比1.6%,提高冶炼强度6%,提高产量7.6%。马钢二铁厂2号高炉应用微型计算机进行称量误差补正后,平均每班累计焦炭误差仅100kg,矿石 At present, many domestic 255m ~ 3 blast furnace sump storage tank feeding system has been technological transformation, the original weighing truck to belt conveyor feed. Hangzhou Iron and Steel, Magang Iron Works No. 4 blast furnace will also sinter and pellets in the tank again under sieve, and the use of fixed weighing funnel dispersion weighing, weighing error correction. Magang Iron Works also used a coke neutron water coke moisture correction. These technical measures have achieved high economic benefits. Only sinter trough sieve, each sintering furnace to reduce the sintering of less than 5% of the powder 10%, you can reduce the coke ratio of 1.6%, increase the smelting strength of 6% and increase the yield of 7.6%. Magang Iron Works No.2 blast furnace after the application of microcomputer error compensation weighing, the average cumulative coke error per class is only 100kg, ore
