太原钢铁公司第三炼钢厂的转炉,以前采用人工停风加料,一炉钢需用石灰700～800公斤,加料时间约需10～15分钟,炉温下降约150～250℃,由此不仅使渣料长期不化,大大降低了去除硫、磷的速度和效率,降炭速度也很缓慢,不仅钢的质量不好,产量也因此无法提高,同时工人的劳动强度也很大。为了改善上述情况,该厂最近试验成功“不停风控制加料法”。这个方法所用的设备构造很简单(如图),主要由储料罐、滑槽和支架三部份组成。储料罐的容量能够装一炉用的渣料。储料罐下部为漏斗,漏斗口有控制闸
Taiyuan Iron and Steel Company’s third steel converter converter, the previous use of manual cutting wind feeding, a furnace of lime required 700 to 800 kg, the feeding time of about 10 to 15 minutes, the temperature dropped about 150 ~ 250 ℃, which not only So that the slag does not long-term, greatly reducing the speed and efficiency of sulfur and phosphorus removal, carbon reduction rate is very slow, not only the quality of steel is not good, so the yield can not be increased, while labor intensity is also great. In order to improve the above situation, the plant recently successfully tested the “cease-fire control feed method.” The equipment used in this method has a very simple structure (pictured). It is composed of three parts: storage tank, chute and bracket. The capacity of the storage tank can be filled with a furnace slag. The lower part of the storage hopper funnel, funnel mouth control gate
