鞍钢燃气厂老工人丁继兴,从1949年鞍钢开工以来,苦练硬工夫,练出在不停煤气的条件下焊接煤气管道的高超技术。据初步统计,从1958年以来,运用这种方法成功地处理了2米以下煤气管道的裂缝、漏洞等五百多处。今年4月,在7号高炉大修的会战中,还用这种方法首次焊接了管径2.3米、煤气压力达600毫米水柱的煤气管道。几年来,丁继兴
Ding Jixing, an old worker of Anshan Iron and Steel Plant, has been working hard since Angzhou Steel started in 1949 and has developed a superb technology for welding gas pipelines without stopping the gas. According to preliminary statistics, since 1958, more than 500 cracks and loopholes in gas pipelines under 2 meters have been successfully handled by this method. In April this year, in the battle for the overhaul of the No. 7 blast furnace, the gas pipeline with a diameter of 2.3 meters and a gas pressure of 600 mmH2O was also welded for the first time by this method. In recent years, Ding Jixing
