我厂∮250×5热轧车间原设备陈旧,设备与工艺事故频繁,产量低,质量差,消耗高,通过1984～1986年近三年来的技术改造,先后对加热炉、轧钢机、辅助设备进行更新与改造。从而开车率提高20～25％,φ10、φ12圆钢椭园度与公差≤±0.2毫米。尤其是钢材表面质量的改观更为显著,产量提高25％,钢材的轧废率由7％下降为2～3％。钢材的合格率提高10％,节能以轧材
Our factory ∮250 × 5 hot rolling workshop original equipment obsolete, frequent equipment and process accidents, low yield, poor quality, high consumption, through the technical transformation of the past three years from 1984 to 1986, has on the furnace, rolling mill, auxiliary equipment To update and transform. Thus driving rate increased by 20 ~ 25%, φ10, φ12 round steel elliptical degree and tolerance ≤ ± 0.2 mm. In particular, the surface quality of steel improved more significantly, the output increased by 25%, the rolling rate of steel reduced from 7% to 2 to 3%. The passing rate of steel increased by 10%, energy saving rolled
