我厂小型轧钢车间为Φ360 ×2/Φ250×5横列式布置,主要生产小型园钢、螺纹钢、扁钢和角钢等型材。近几年来,为提高产品成材率采取了不少措施,但始终徘徊在95.5％左右。自1985年年初进行负偏差试轧到五月份成批生产以来,成材率得到了较大幅度的提高。 我们对生产批量大的12毫米和14毫米的园钢、螺纹钢采取了负偏差轧制,共轧制了6342.92吨,节约钢材135.26吨,成材率平均增加2.05％,增加纯利润21.6万元。
I plant a small rolling workshop for Φ360 × 2 / Φ250 × 5 line arrangement, the main production of small Park Steel, rebar, flat steel and angle steel and other profiles. In recent years, many measures have been taken to improve the product yield, but it has remained at about 95.5%. Since the beginning of 1985, negative deviation test rolling to mass production in May, the finished product rate has been more substantial increase. Negative deviation rolling was carried out on 12 and 14mm round steel bars and rebar with a large production volume, 6342.92 tons of rolled steel and 135.26 tons of steel were saved. The average finished product rate increased 2.05% and the net profit increased by 216,000 yuan.
