rolling mill-圣霖国际【开拓创新】

按轧制品种、轧机型式和公称尺寸来命名。“公称尺寸”的原则对型材轧机而言，是以齿轮座人字齿轮节圆直径命名。

It is named according to the varieties of rolling， the type of rolling mill and the nominal size. The principle of "nominal size"

For rolling mills， they are named after the gear ring and the pitch diameter of the herringbone gear.

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")，250rolling mill， 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.

辊式轧机生产率可以很高，rolling mill，有的可达到2000-4000 件/小时甚至更高，850rolling mill，易于实现自动化生产。总之，辊式轧机适用于对产品精度要求不高，且同时轧制一个或几个零件的情况。辊式轧机是三种类型中运用***多的一种。圆弧式轧机适用于大批量的为以后锻造供坯的生产情况。

The productivity of the roller mill can be very high， some can reach 2000-4000 pieces / hour or even higher， and it is easy to realize automatic production. In conclusion， the roll mill is suitable for the low accuracy of products and rolling one or several parts at the same time. Roll mill is the most widely used in three types. The circular arc mill is suitable for large quantities of production for forging later.
