莱芜钢铁总厂特殊钢厂有一列(?)300×5的轧钢机,年生产能力8万t。所用加热炉为两段推钢式,有效面积47.35m~2。该炉自1986年获全国小型节能冠军炉后,燃料单耗年年有所下降,1991年可比单耗折标准煤仅33.50kg/t,与1990年相比降低了7.1％,与1986年相比降低了10.2％。其中有5个月炉子平均热效率均高达70％以上,此燃耗指标不仅在国内领先,而且达到了国际先进水平。

Laiwu Iron and Steel Plant Special Steel has a column (?) 300 × 5 of the rolling mill, the annual production capacity of 80,000 t. The furnace used for two sections of steel, the effective area of ​​47.35m ~ 2. The furnace since 1986 won the national small-scale energy-saving champion furnace, fuel unit consumption declined year after year, compared with 1991 single unit consumption of standard coal only 33.50kg / t, compared with 1990 decreased by 7.1% Than the decrease of 10.2%. Among them, the average thermal efficiency of the stoves in five months was as high as over 70%. This fuel consumption index not only leads in the country, but also reaches the international advanced level.
