1984年9月日本钢管公司 Fukuyama 钢铁厂第三炼钢车间的5号板坯连铸机正式投入运行。1985年4月这台连铸机创造了板坯连铸铸速为每分2.5米的世界纪录。连铸机高速运行的目的是为了直接与板坯轧机相联,以形成最佳的直接热轧布局。据称,由于使用了上述高速连铸机,生产能力从每月18万吨上升到25万吨(板厚220、宽700～1650毫米);由于直接热轧率上升到85%,从而使加热每吨钢的能耗从30万 kcal 降至5万 kcal。当板坯连铸机运行时,钢水先进入一只容量为300吨的钢水包,钢水预先用先进的 In September 1984, the No. 5 slab caster at the third steelmaking plant of the Japanese steel pipe company Fukuyama Steel Works was officially put into operation. In April 1985, the caster created a world record of slab casting speed of 2.5 meters per minute. The purpose of high speed continuous casting machine is to be directly associated with the slab mill to form the best direct hot-rolled layout. Allegedly, due to the use of the high-speed caster, the production capacity has risen from 180,000 tons per month to 250,000 tons (thickness 220, width 1,700 mm to 1,650 mm); the direct hot rolling rate has increased to 85% Energy consumption per ton of steel dropped from 300 kcal to 50,000 kcal. When the slab caster is running, the molten steel first enters into a ladle with a capacity of 300 tons. The molten steel is advanced with an advanced
