鞍钢七号高炉是我国大型高炉之一,1953年曾经过一次改建,今年二月停炉进行这次改建性大修。这次改建后的炉底,其最下三层是满铺炭砖,上六层是炭砖和特级高铝砖的综合砌体,炉缸采用四层炭砖。这样的炉底内衬质量是大大提高了,更好地适应了高炉强化冶炼的技术发展要求。炉底砌筑是在前一工序——高铝砖加工精度大大
Anshan Iron and Steel No. 7 blast furnace is one of the large-scale blast furnaces in China. It was once rebuilt in 1953. In February of this year, the furnace was shut down for this rebuilding overhaul. After the reconstruction, the bottom three floors are filled with carbon bricks, the upper six floors are integrated masonry bricks and super high-alumina bricks, and the hearth uses four-layer carbon bricks. The quality of such bottom lining is greatly improved, and it is better adapted to the technical development requirements of blast furnace smelting. Furnace masonry is in the former process - high alumina brick machining accuracy
