武钢高炉炉前渣铁沟及英巴沟嘴改造

Revamp of slag-iron runner and inba runner mouth of blast furnace in WISCO

介绍武钢炼铁厂对高炉炉前渣铁沟、英巴渣沟嘴以及残铁沟嘴等进行的技术改造攻关。从原来比较落后的人工敷设修筑沟嘴法,逐步完善为采用先进的预制件结构沟嘴,降低了工人的劳动强度,改善了作业环境,降低了人工及材料成本,提高了高炉生产效率。

The present paper introduces the technological revamp project of the iron-slag runner, Inba slag runner mouth and residual iron runner mouth of the BF in the General Iron-making Plant of WISCO. The technoology for the revamp project advances gradually from the reatively backward method of laying the runner mouth by manual work in the earlier days to the more advanced method of pre-fabrication of the structure elements for the runner mouth at the present time. As the results the labour intensity for the worker has been reduced, the working environment improved, cost for man power and materials lowered and productivity of the blast furnace raised.
