一冶建研所分别和湖北鄂城钢铁厂、河北峰峰矿务局钢铁厂组成三结合小组,在鄂钢100立方米1号高炉中修和峰局钢铁厂28立方米的2号高炉大修中,采用了2号冷捣炭素料内衬。这次采用了沥青和焦油作为粘结剂,取消沥青粉,可就地取材。这样不但劳动条件进一步改善,还保证了炭捣体的匀质性,提高了捣打质量,绝大部分捣打密度为1.50
Yiye Jianye Research Institute and the Hubei Echeng Iron and Steel Plant and the Hebei Fengfeng Mining Bureau Iron and Steel Plant form a three-combination group. The No. 2 blast furnace overhaul of 28 cubic meters of the No. 1 blast furnace in the 100 cubic meters of the Egang Steel Works was completed. In the middle, a No. 2 cold heading carbon material liner was used. This time, asphalt and tar were used as binders, asphalt powder was removed, and materials were available locally. This will not only further improve the working conditions, but also ensure the homogeneity of the anthrax and improve the quality of the beating. Most of the beating density is 1.50.
