摘要
随着宝钢“三脱率”的提高及喷吹方式的改变 ,混铁车的平均寿命由 1 2 0 0炉次以上降至 90 0炉次左右。通过分析混铁车各部位的损毁特点及原因 ,选择合适的骨料 ,调整抗氧化剂的种类和加入量 ,强化基质 ,使Al2 O3-SiC -C砖的抗氧化性和抗渣性等关键性能得以提高。混铁车的平均寿命由改进前的 90 0炉次提高到 1 0 5 0炉次左右。
To increase the service life of metal mixer, new Al 2O 3-SiC-C bricks are developed by analyzing the wear features and reasons of various areas of metal mixer, choosing suitable aggregates, adjusting variety and addition of antioxidant and toughening the matrix.The new developed bricks have higher oxidation resistance and slag resistance compared with the original bricks.The service life of metal mixer after using the new brick increased from 900 heats to about 1050 heats.
