保持工作輥的上輥和下輥相對于軋機(jī)中心線對稱且在軸線方向上移動。這種的工作輥移動的設(shè)計，是用來改變工作輥和支撐輥的偏移需要大的移動量。這種大移動量的采用需要大量的改裝費用，并且需要解決很多問題.

The upper and lower rolls of the work roll are symmetrical and move in the direction of the axis of the rolling mill. The movement of this work roll is designed to change the shift of work rolls and support rolls to require large amounts of movement. The use of this large shift of momentum requires a lot of modification costs, and many problems need to be solved.

H型鋼在冷床上直立冷卻后，由輥道送至變節(jié)距輥式矯直機(jī)進(jìn)行長尺矯直，經(jīng)成排臺架成排后，由冷鋸機(jī)切成6～24m定尺。切成定尺的軋件經(jīng)人工目測檢查后，進(jìn)入堆垛臺架堆垛，經(jīng)打捆、稱重、標(biāo)牌后進(jìn)入成品臺架，由成品跨吊車吊運入庫、發(fā)貨。

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.

半閉口式機(jī)架是機(jī)架與機(jī)架蓋之間采用斜楔連接的一種機(jī)架。這種機(jī)架兼有開口式機(jī)架和閉口式機(jī)架的優(yōu)點，裝卸、換輥方便，制造容易，并有較高的剛度，故一般大中型的型鋼軋機(jī)都采用這種形式的機(jī)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.

軋機(jī)專業(yè)廠家說，熱軋機(jī)的優(yōu)點主要可以歸納為三個方面。一點，采用熱軋可以明顯的減少能耗，降低成本。此外，熱軋時可以發(fā)揮出較高的金屬塑性，而且所產(chǎn)生的變形抗力較小，能夠有效的防止金屬出現(xiàn)嚴(yán)重的變形問題。

The mill manufacturer explains that the advantages of the hot rolling mill can be summed up in three aspects. First, the use of hot rolling can significantly reduce energy cumption and reduce costs. In addition, hot rolling can give full play to the high metal plasticity, and the deformation resistance is small, which can effectively prevent the serious deformation of the metal.
