保持工作輥的上輥和下輥相對于軋機中心線對稱且在軸線方向上移動。這種的工作輥移動的設計，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.

實現(xiàn)金屬軋制過程的設備。泛指完成軋材生產(chǎn)全過程的裝備，包括有主要設備、輔助設備、起重運輸設備和附屬設備等。但一般所說的軋機往往僅指主要設備。

A device for a metal rolling process. Generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. Generally speaking, rolling mills usually refer to only the main equipments.

在鍛造和軋制生產(chǎn)中，鋼坯一般在完全燃燒火焰的氧化氣氛中加熱。采用不完全燃燒的還原性火焰（即“自身保護氣氛”）來直接加熱金屬，可以達到無氧化或少氧化的目的。這種加熱方式稱為明火式或敞焰式無氧化加熱，成功地應用于轉(zhuǎn)底式加熱爐和室式加熱爐。

In forging and rolling production, billets are usually heated in the combustion atmosphere of complete combustion flame. The direct combustion of metal can be achieved by the incomplete combustion of reduced flame (i.e., the "self protective atmosphere"), which can achieve the  of no oxidation or less oxidation. This heating method is called open flame or open flame oxidation free heating, which has been successfully applied to rotary hearth furnace and chamber heating furnace.

在經(jīng)過改進之后，目前的軋機設備采用的是被動一軋一拖式生產(chǎn)方式，可以實現(xiàn)兩道軋制成型，不僅解決了速度配合問題，而且改變了傳統(tǒng)的四道軋制方式，生產(chǎn)效率明顯提高。

After the improvement, the current  mill equipment adopts a passive one rolling and towing mode of production, which can realize two rolling forming. It not only solves the problem of speed matching, but also changes the traditional four way rolling method, and the production efficiency is  improved.
