建国以来,我国炼铁技术发展的非常迅速。特别是在高风温、高强度和精料方面,形成了一个飞跃阶段。由于冶炼强度的逐年提高,使炉体各部分的侵蚀速度颇不一致。这就对炉体构造和附属设备不断地提出了新的要求。本文拟就在高冶炼强度(>1.2)条件下,如何更好地适应新的要求,提出一些探讨性意见,供有关单位参考。一、本钢几座高炉历代的侵蚀情况本钢有二座中型高炉(329米~3和332米~3各一座)和二座大型高炉(917米~3),这四座高炉的年代都比较久。由于
Since the founding of our country, the development of ironmaking technology in our country is very rapid. Especially in the high temperature, high strength and concentrate, has formed a leap phase. As the smelting strength increased year by year, so that various parts of the furnace erosion rate is quite inconsistent. This constantly poses new requirements for furnace construction and ancillary equipment. In this paper, under the conditions of high smelting strength (> 1.2), how to better adapt to the new requirements, put forward some suggestions, for the relevant units for reference. First, the history of several blast furnaces Benxi Iron and Steel Erosion erosion Bengang has two medium-sized blast furnace (329 m ~ 3 and 332 m ~ 3 each) and two large blast furnace (917 m ~ 3), the four blast furnace age are more Long. due to
