我厂高炉冶炼本地矿时,容易在渣口带铁。这种不良的现象加剧了渣口小套的烧损,也容易引起渣口爆炸。在最不好的情况下,一天就烧坏2个渣口小套,严重地影响了高炉正常生产。后来在冶金部工作组张乃鹏同志的协助下,制成了用紫铜棒锻制小套头部,再和鑄铜小套后部焊接而成的渣口小套。经长期使用其效果非常好,渣口小套 I plant blast furnace smelting local mine, easy to slag in the mouth. This bad phenomenon exacerbated a small set of burning slag mouth, but also easily lead to slag mouth explosion. In the worst case, one day a small set of 2 small mouths burn out, seriously affecting the normal production of the blast furnace. Later, with the assistance of Comrade Zhang Naipeng, the working group of the Ministry of Metallurgy, a small sleeve made of copper rods forging the small heads and then welded to the rear of the small copper sleeves was made. After long-term use of its effect is very good, a small set of slag mouth
