就目前的实际情况来看,在全国生产的各种类型的生铁高炉中,以600米~3犁高炉的各项生产技术经济指标较差。扩大风口进风面积以提高冶炼强度,无疑是一种增加生铁产量的有效手段,但是高炉炉型,装备设施、原燃料条件、高炉所选择的作业制度的合理性,以及冶炼工作者的操作水平,都会直接影响到这一措施的效果。我们所希望的是在降低焦比的同时来提高高炉的冶炼强度。本文就新余钢铁厂六号(600米~3)高炉在风口
At present, the actual situation, in the production of various types of pig iron blast furnace, 600 meters to 3 plow blast furnace production technology and economic indicators are poor. Expanding the inlet area of the tuyere to increase the smelting strength is undoubtedly an effective way to increase the production of pig iron. However, the reasonableness of the blast furnace type, equipment and facilities, raw fuel conditions, the operation system selected by the blast furnace and the operation level of the smelting workers , Will have a direct impact on the effectiveness of this measure. What we want is to increase the smelting strength of the blast furnace while reducing the coke ratio. In this paper, Xinyu Iron and Steel Works on the 6th (600 m ~ 3) blast furnace at the outlet
