H型钢在冷床上直立冷却后，750rolling mill，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，650rolling mill，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.

四棍轧机的工作辊直径较小，传递轧制力矩，轧延压力由直径较大的支承辊承受。这类设备的主要优点是相对刚度较大，压下量大、轧延力小，700rolling mill，可轧制较薄的板材，长春rolling mill，也包括有可逆和连轧两种。

The working roll diameter of the four bar mill is ***all， and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness， large reduction， low rolling force， thin rolled sheets， and reversible and continuous rolling two.

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.
