实现金属轧制过程的设备。泛指完成轧材生产全过程的装备，800轧机优势，包括有主要设备、辅助设备、起重运输设备和附属设备等。但一般所说的轧机往往仅指主要设备。

A device for a metal rolling process. Generally refers to the equipment that completes the whole process of rolling material production，800轧机， including main equipment， auxiliary equipment， lifting and transportation equipment and auxiliary equipment. Generally speaking， rolling mills usually refer to only the main equipments.

在锻造和轧制生产中，钢坯一般在完全燃烧火焰的氧化气氛中加热。采用不完全燃烧的还原性火焰（即“自身保护气氛”）来直接加热金属，可以达到无氧化或少氧化的目的。这种加热方式称为明火式或敞焰式无氧化加热，成功地应用于转底式加热炉和室式加热炉。

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，800轧机生产厂家， which has been successfully applied to rotary hearth furnace and chamber heating furnace.

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.
