君津厂4号高炉(4930米~3)1980年12月焦比为406公斤/吨生铁,这是由于改善高炉操作技术、配料的可还原性、使用活动的炉喉保护板而获得最好的气流状况和对粒状物料的防护的结果。此外还采用了一种高炉操作的计算机中心控制系统,精确测出炉料软熔带的形式,在生产低硅生铁时监视高炉运行、透气性和炉气分布,以便调剂高炉的行程。另外还包括使用低硅酸和含低铁
Junjin Plant No. 4 blast furnace (4930m ~ 3) In December 1980, the coke ratio was 406kg / t pig iron, which is due to the improved blast furnace operation technology, the reducibility of the ingredients, and the use of active throat protection plates to obtain the best Air flow conditions and the results of the protection of granular materials. In addition, a blast furnace-operated computer center control system was used to accurately measure the form of charge refuse, monitoring blast furnace operation, gas permeability and furnace gas distribution in the production of low silicon pig iron in order to adjust blast furnace travel. Also includes the use of low-silicic acid and low iron
