美国钢厂和红厂,投资2亿美元,经过17个月奋战,建成了世界上最大的具有70万吨/年生产能力的带钢电镀锌作业线,于1986年2月投产。在一个很宽镀层重量范围内,用锌或铁-锌合金的不同配比生产带钢单面或双面镀锌板。带钢宽915～1830mm,厚0.60～1.50mm,最大镀层重量,上面为40～100g/m~2,底面为40～60g/m~2,最大卷重6,0000磅。冷轧退火后碳钢的屈服强度达到21000至80000磅/英时~2,典型产品有CQ、DQ、DDQ、DQSK,是一些高强度优质钢。该作业线呈回转式工序,带钢生产线长度4300英尺,具有线性跟踪,带卷储藏、带卷精度检测及计算机网络控制等设施。贮仓长876英尺,宽125英尺,高82英尺,可容放2820个
US steel mills and Red Mills invested 200 million U.S. dollars and after 17 months of fighting, built the world’s largest galvanized steel strip production line with a production capacity of 700,000 tons / year and started production in February 1986. In a wide range of coating weights, with zinc or iron - zinc alloy of different ratio of the production of single or double-sided galvanized steel strip. Strip width 915 ~ 1830mm, thickness 0.60 ~ 1.50mm, the maximum coating weight, the above 40 ~ 100g / m ~ 2, the bottom of 40 ~ 60g / m ~ 2, the maximum weight of 6,0000 pounds. Cold-rolled annealed carbon steel yield strength of 21,000 to 80,000 pounds per lb ~ 2, typical products are CQ, DQ, DDQ, DQSK, is a number of high-strength high-quality steel. The line is a rotary process, the strip production line length 4300 feet, with a linear tracking, coil storage, coil accuracy testing and computer network control facilities. Storage 876 feet long, 125 feet wide, 82 feet high, can accommodate 2820
