福山5号高炉内容积4617米~3,1973年11月8日点火,1983年10月26日停炉,炉龄约10年,累计产量3182万吨。《日本钢管技报》1984年第102期报道了该高炉的十年操作总结,现摘译其中“一代炉龄中操作”和“延长炉龄的经验”两部分。一、一代炉龄中操作5号高炉的第一代炉役10年间经历了两次石油危机,按操作情况可分为两个时期:1974～1980年前7年是高产低燃料比期,1981～1983年的后3年因油价上涨实行全焦 Fukuyama No. 5 blast furnace volume of 4617 meters ~ 3, November 8, 1973 ignition, October 26, 1983 shutdown, furnace age of about 10 years, the cumulative output of 31.82 million tons. “Nippon Steel Bulletin” No. 102, 1984 reported a summary of the operation of the blast furnace for the past 10 years, now extract “one of the furnace operation in the furnace” and “to extend the experience of furnace” in two parts. First, the first generation of blast furnace furnace operation in the first generation of furnace experience 10 years, two oil crises, according to the operation can be divided into two periods: 1974 to 1980 is the first seven years of high yield low fuel ratio, 1981 Three years after 1983, all the coke was launched due to rising oil prices
