一、引言自1981年后,澳大利亚的钢铁工业和其他国家一样,进行了一个大的合理调整,粗钢产量已从年产900万吨,降低到年产680万吨,生产的高炉,已从12座减至5座。在布罗肯·希尔钢铁公司的堪培拉港厂,现有两座高炉生产,四高炉内容积1815米~3,炉缸直径9米(29.5呎),五高炉内容积3045米~3,炉缸直径12.15米(40呎)。自1984年以后,已要求两座高炉在产量最高的水平上操作,同时在控制成本和改善铁水质量方面,受到很大压力,而对炉体寿命也要求尽可能延长。本文首先介绍近三年高炉操作进步的主要方面是精选原料、操作 I. INTRODUCTION Since 1981, Australia’s iron and steel industry, like other countries, has made a major and reasonable adjustment. Its output of crude steel has dropped from 9 million tons a year to 6.8 million tons a year. The production of blast furnaces has ranged from 12 reduced to 5 seats. In Brocken Hill Steel Canberra Port, the existing two blast furnace production, the four blast furnace volume 1815 m ~ 3, the hearth diameter of 9 meters (29.5 feet), five blast furnace volume of 3045 m ~ 3, the furnace Cylinder diameter 12.15 meters (40 feet). Since 1984, two blast furnaces have been required to operate at the highest levels of output while putting a great deal of strain on cost control and hot metal quality improvements, while keeping furnace life as long as possible. This article first introduces the main aspects of blast furnace operation in recent three years is the selection of raw materials, operation
