三明钢铁厂1号高炉(350m~3)是由255m~3扩容改造的,于1994年1月19日顺利出第一炉铁。1994年生产铁149231.914t,入炉焦比644kg/t铁。1995年产铁195359.232t,入炉焦比600kg,1995年比1994年多产铁46127t,增长30.91%,焦比降低44kg。1996年产铁233351.882t,比1995年多产铁37993t,增长19.45%,入炉焦比557kg,比1995年降低29kg/t.铁。三年主要技术指标见表1。 1997年1～5月份产铁103587t,比1996年同期多产铁14670t,增长15.82%,入炉焦比533kg,比去年同期降低29kg。节焦3114t,节焦价值188.72万元。1～5月份主要技术经济指标见表2。
Sanming Iron and Steel Plant No. 1 blast furnace (350m ~ 3) is a 255m ~ 3 capacity expansion transformation, in January 19, 1994 successfully out of the first furnace iron. In 1994 the production of iron 149231.914t, into the furnace coke than 644kg / t iron. In 1995 iron production 195359.232t, into the furnace coke ratio 600kg, in 1995 than in 1994 prolific iron 46127t, an increase of 30.91%, reduce coke ratio 44kg. In 1996, 233351.882t of iron was produced, 37993t more than that of 1995, an increase of 19.45%, and 557kg into the furnace coke, down 29kg / t from 1995. Three major technical indicators in Table 1. From January to May 1997, iron production was 103587t, a year-on-year increase of 14670t over that of the same period of 1996, an increase of 15.82%. The coke ratio into the furnace was 533kg, a decrease of 29kg over the same period of last year. Day coke 3114t, section coke value of 188.72 million. 1 May main technical and economic indicators in Table 2.
