軋機(jī)的輥系在換輥前可以預(yù)安裝并調(diào)整好，軋機(jī)停車后只需較短時(shí)間即可換上新輥系。而新輥系經(jīng)少量試軋后即能軋出合格產(chǎn)品。因此這種軋機(jī)可調(diào)性能好，成材率高。

短應(yīng)力線軋機(jī)可制成二輥式、三輥式或四輥式多種形式的軋機(jī)。在型鋼、線材和板帶鋼生產(chǎn)中部有應(yīng)用。

The roll system of rolling mill can be pre installed and adjusted before changing the roll. After the rolling mill , it only needs a short time to replace the new roll system. The new roll system can be rolled out of the qualified product after a small amount of test rolling. Therefore, this kind of rolling mill has good adjustable performance and high yield.  

The short stress line mill can be made into two - roll, three - roll, or four - roll type rolling mills. It is applied in the middle part of steel, wire and strip steel.

連續(xù)加熱爐連續(xù)加熱爐包括推鋼式加熱爐、步進(jìn)式爐、轉(zhuǎn)底式爐、分室式爐等連續(xù)加熱爐，但習(xí)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(gè)同向旋轉(zhuǎn)的帶有楔性凸起的模具中間，棒材在模具的帶動(dòng)下，作與模具反向的回轉(zhuǎn)運(yùn)動(dòng)，同時(shí)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.
