1.Abstract: A preliminary investigation was made on hearth damage of a number of furnaces in China,and the analysis and discussion are presented for reasons of hearth damage in this paper.The main reasons of ring crack of the hearth are:1.Improper physical and chemical properties of baked carbon bricks.2.The thermal stress existing in carbon bricks,alumina bricks and the furnace shell.The formation of the ring crack aggravates the abnormal erosion of the hearth.
文摘:结合鞍钢2号和7号等高炉和2号高炉的调查结果，对国内部分高炉炉缸破损情况进行初步调查，对炉缸破损原因做了初步分析和讨论，认为造成我国高炉炉缸环形断裂的主要原因是由于碳砖自身物化性能差以及炉缸碳砖和高炉炉壳之间的热应力；环裂的出现加剧了炉缸的异常侵蚀。

10.Sponge zirconium was employed as raw material to prepare wedge-like specimens of Zr_(52.5)Cu_(17.9)Ni_(14.6)Al_(10)Ti_5 quinary alloy by a tilt casting method using ladle-hearth-type arc furnace. The effect of active element Sc on the glass forming ability and crystallization kinetic parameters of the quinary alloy is investigated.
