为解决炼铁用焦及合理地利用资源,许多缺焦地区开展了型焦研制工作和冶炼试验。四川省达县地区万福钢铁厂及广东省兴宁县龙北钢铁厂至今仍用型焦炼铁。鹤壁冷压型焦在全国近四十个研制单位中质量是比较好的(见图1)。在13米~3高炉上连续生产四年多,为进一步验证型焦的质量,于1978年12月4日至14日在河南省安阳地区林县钢铁厂100米~3高炉上进行第二次冶炼试
In order to solve the problem of using coke and making rational use of resources in ironmaking, many types of coke development and smelting tests have been carried out in many areas lacking in coke. Wanda Iron and Steel Plant in Daxian District of Sichuan Province and Xingning County, Guangdong Province, Longbei Iron and Steel Plant still use type coke iron. Hebi cold-pressure coke in the country nearly 40 development units in the quality is better (see Figure 1). In 13 meters to 3 blast furnace for more than four consecutive years, in order to further verify the quality of coke, December 4, 1978 to 14 in Anyang, Henan Province, Lin County Iron and Steel Plant 100 meters to 3 blast furnace for the second time Smelting test
