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.
半闭口式机架是机架与机架盖之间采用斜楔连接的一种机架。这种机架兼有开口式机架和闭口式机架的优点，装卸、换辊方便，制造容易，并有较高的刚度，故一般大中型的型钢轧机都采用这种形式的机架。
A semi closed frame is a frame with a wedge between the frame and the frame cover. The rack has the advantages of open frame and closed frame. It has the advantages of loading and unloading, easy roll changing, easy manufacture and high rigidity. Therefore, a large and medium-sized steel mill is adopted in this form.
楔横轧机类型有辊式、板式和单辊弧式楔横轧机。三种类型的楔横轧机相比，板式楔横轧机模具制造较为简单，模具的调整比较容易，因而轧件的精度较高，并且工艺可靠.
The cross wedge rolling mill has roller type, plate type and single roll arc cross wedge rolling mill. Compared with the three types of cross wedge rolling mill, the mould manufacturing of the plate type cross wedge rolling mill is simpler and the adjustment of the die is easy, so the precision of the workpiece is high and the process is reliable.
