今年上半年(1955年)我廠熱工工作很難令人滿意,熔煉速度不快,生產極不穩定。爐齡初期頭二三十爐浪費設備生產能力,總熔煉時間在八小時以上,爐齡中期(40—230爐)情况正常,平均在6∶40左右;後期(230—330爐以上)變慢,平均7∶20左右。再从快速煉鋼率來看,初期為零;中期30％;後期僅達7％。 進入第三季以來這種歷史性的生产規律被打破了,而代之以生产的平衡性和穩定性。以我廠某號平爐來看;七月一號中修,十一月五號停爐再中修,各月平均熔煉時间
The first half of this year (1955) thermal work in our plant is difficult to satisfactory, smelting speed unpleasant, production is extremely unstable. The first twenty or thirty furnaces at the beginning of the furnace weretes the equipment production capacity, the total smelting time is over eight hours, and the middle of the furnace age (40-230 ovens) is normal with an average of around 6:40; the late period (over 230-330 ovens) is slowed down , An average of about 7:20. Again from the rapid steelmaking rate of view, the initial zero; mid-30%; late only 7%. Since the third quarter of this historic law of production has been broken, and replaced by the balance of production and stability. To my factory a flat furnace point of view; July 1 in the repair, shut down in November 5th and then repair, the average melting time of each month
