马钢钢研所与二炼铁厂合作开发的高炉冷却壁断管再植新技术在现场使用已获成功。自1989年3月以来,第二炼铁厂的3号和4号高炉运用该项新技术对漏水冷却壁的断管进行了再植,再植的断管迄今尚无漏水。该项技术是用胶接方式修复高炉冷却壁断管的,并用金属软管将新管接头与炉壳柔性连接,这样可避免水管的二次断裂。该项技术具有操作简单、易于掌握,安全可靠的优点。采 Magang Iron and Steel Institute and the second ironworks co-developed blast furnace cooling pipe replantation of new technologies in the field has been successfully used. Since March 1989, the No.3 and No.4 blast furnaces of No.2 Iron Works have used this new technology to replant broken tubes in leaking stave, so far there is no leakage of replantation tubes. The technology is used to repair the blast furnace cooling stave pipe, and metal hose to the new pipe fittings and shell flexible connection, so as to avoid the secondary pipe fracture. The technology has the advantages of simple operation, easy to grasp, safe and reliable. Mining
