武钢高炉先后两次进行了大料批正分装试验.结果表明:在一定的原料条件下,选择适当大小的批重,正分装,比正同装能更进一步改善煤气利用.降低焦比10～30kg/t.只要上下部操作制度选择适当,可以改善料柱透气性.在降低焦比的同时,提高冶炼强度.提高炉料质量、采用多种措施维护好操作炉型、保持煤气中心通路,是能够坚持使用大料批正分装的重要因素.
The blast furnace of WISCO successively carried out the large-batch batch positive test in two batches. The results showed that under the condition of certain raw materials, the batch with the proper size was selected, and it was installed more than the same batch to further improve the gas utilization. 10 ~ 30kg / t. As long as the operation of the upper and lower part of the appropriate choice of systems, can improve the permeability of the column. In reducing the coke ratio at the same time, improve the smelting strength. Improve the quality of charge, using a variety of measures to maintain the operating furnace, , Is able to adhere to the large batch is an important factor in the sub-packaging.
