輥系快速整體更換不需吊車，采甩軋輥牽引小車和橫移臺車結合的換輥方式，導衛(wèi)橫梁安裝在軋機軸承座上，更換軋輥時,導衛(wèi)及橫梁隨輥系整套從牌坊窗口中拖出，一次換輥時間僅為20min.

You don't need to replace the whole fast roller roller way for mining crane, trolley and swing roller traversing 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.

連續(xù)加熱爐連續(xù)加熱爐包括推鋼式加熱爐、步進式爐、轉底式爐、分室式爐等連續(xù)加熱爐，但習慣上常指推鋼式爐。連續(xù)加熱爐多數(shù)用于軋制前加熱金屬料坯，少數(shù)用于鍛造和熱處理。

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.

楔橫軋工藝的基本原理是，將加熱后的棒材送入兩個同向旋轉的帶有楔性凸起的模具中間，棒材在模具的帶動下，作與模具反向的回轉運動，同時材料發(fā)生徑向壓縮變形和軸向延伸變形，從而成形階梯軸類零件。

The basic principle of the cross wedge rolling process is to send the heated bar into the middle of two same revolving moulds with wedge-shaped protrusi. The rod is driven by the mold to make the reverse rotation movement with the mold. At the same time, the material has radial compression deformation and axial extension deformation, thus forming a staircase type part.
