为了弄清高炉处于低燃料比时的各种现象,日本钢管公司于1981年9—11月间在福山3高炉上进行了大型高炉的极低燃料比试验。该炉容积3223米~3,75年1月投产,试验时炉役已处于中后期。试验中采取以下措施以降低燃料比:1.改善原料条件:炉料中烧结矿比从83%增至97%,提高了烧结矿的还原性能;

In order to understand various phenomena when the blast furnace was at a low fuel ratio, the Japanese tube company conducted a very low fuel ratio test on a large blast furnace at Fukuyama-No.3 blast furnace in September-November 1981. The furnace volume of 3223 m ~ 3, put into operation in January 75, when the furnace trial has been in the late. In the experiment, the following measures were taken to reduce the fuel ratio: 1. Improvement of raw material conditions: the sinter ratio in the charge increased from 83% to 97%, improving the reduction performance of sinter;
