520轧机报价承诺守信

辊系快速整体更换不需吊车，采甩轧辊牵引小车和横移台车结合的换辊方式，导卫横梁安装在轧机轴承座上，更换轧辊时,导卫及横梁随辊系整套从牌坊窗口中拖出，一次换辊时间仅为20min.

You don't need to replace the whole fast roller roller way for mining crane, trolley and swing roller tr***ersing trolley with the guide beam is installed on the bearing seat of rolling mill, roll changing, guide and beam with roll set pulled from the housing window, a roll change time is only 20min.

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.

使用热轧的第二个优点就在于其可以适当的改善金属以及合金材料的加工工艺性能。也就是说，其可以把较大的晶粒进行破碎，同时可以减少裂纹的出现，这样一来，也就相当于减少了铸造过程中的缺陷问题，提高合金的加工性能。

The second advantage of hot rolling is that it can appropriately improve the processing performance of metal and alloy materials. That is to say, it can break the larger grain and reduce the appearance of the crack, which is equivalent to reducing the defects in the casting process and improving the processing performance of the alloy.
