关于机械产量，二十世纪七十年代后期，控制冷却技术的发展使得钢板轧制中的TMCP技术得到广泛发展。
With regard to mechanical production, the development of cooling technology in the late 1970s made the TMCP technology develop widely in steel plate rolling.
H型钢在冷床上直立冷却后，由辊道送至变节距辊式矫直机进行长尺矫直，经成排台架成排后，由冷锯机切成6～24m定尺。切成定尺的轧件经人工目测检查后，进入堆垛台架堆垛，经打捆、称重、标牌后进入成品台架，由成品跨吊车吊运入库、发货。
H type steel upright in the cooling bed after cooling by roller to pitch roller straightening machine straightening ruler, the rows of bench rows, a cold sawing machine into 6 ~ 24m length. The rolled pieces, which are cut into fixed lengths, are inspected and inspected after manual inspection. They enter stacks stacking, and then enter the finished rack by bundling, weighing and sign.
上轧辊为液压式平衡装置，电动压下，压下量480mm，压下速度60mm／s，正常轧制时下辊固定，上辊压下。换品种和使用较小直径的轧辊时，下轧辊用垫片组调节其水平度.
The upper roller is the hydraulic balance device, the electric press down, the press down 480mm, the down speed 60mm / s, the normal rolling roll fixed and the upper roller. When changing varieties and using ***aller diameter rolls, the lower roll can be adjusted by the gasket group.
楔横轧技术是一种低耗的***生产工艺在连杆生产线上采用楔横轧制坯热模锻压力机成形工艺生产连杆锻件具有其它锻造工艺无法相比的独特优势与辊锻工艺相比材料利用率提高10%以上劳动生产率提高30 50%
Cross wedge rolling technology is an advanced production process with high precision, high efficiency, high efficiency and low cumption. On the connecting rod production line, the forming process of the die forging press of the wedge rolling blank is adopted to produce the connecting rod forgings with the unique advantages of other forging processes. Compared with the roll forging process, the utilization ratio of materials is raised by more than 10% of the labor productivity by 3050%.
