一、引言鞍钢十号高炉于1963年12月27日开炉(第二代),1972年6月17日停炉,一代炉令8年零6个月,除休风时间,实际生产3076.5日。一代主要技术经济指标如表1。十高炉开炉后不久,就达到了较高的冶炼强度,1964年利用系数为1.681,冶炼强度0.88;1965年利用系数即上升到1.704,冶炼强度为0.909;1966年大幅度提高,利用系数达2.119,冶炼强度为1.102。炉役后期,由于炉身冷却设备严重破损,炉皮鼓胀、烧穿屡屡发生,采取了局部,甚至全部打水。另外,炉缸二段冷 I. Introduction Anshan Iron and Steel Co., Ltd. No. 10 blast furnace opened in December 27, 1963 (second generation), June 17, 1972 shutdown, a generation of furnace order 8 years and 6 months, except for the time off, the actual production 3076.5 days . A generation of major technical and economic indicators in Table 1. Ten furnace blast furnace shortly after it reached a higher smelting strength, the utilization factor of 1968 was 1.681, smelting strength of 0.88; 1965 utilization factor that rose to 1.704, smelting strength of 0.909; 1966 substantial increase in utilization factor of up to 2.119, smelting strength of 1.102. Late furnace, due to severe damage to the shaft cooling equipment, furnace skin bulging, burns often occur, took a partial, or even all water. In addition, the second section of the hearth cold
