在開始軋制之前，由高壓水除鱗裝置利用高壓水對(duì)坯料表面的氧化鐵皮進(jìn)行清理，以避免軋制過程中氧化鐵皮的壓入，從而保證終產(chǎn)品質(zhì)量。

Before starting rolling, the high pressure water descaling device is used to clean the scale of billet surface by high pressure water, so as to avoid the indentation of oxide scale during rolling process, so as to ensure the final product quality.

所謂低溫?zé)彳埵侵干愿哂谠俳Y(jié)晶溫度下的軋制。提高軋制溫度可以降低軋件溫度的屈服應(yīng)力，使變形功降低。但是由于變形功可以轉(zhuǎn)化為熱量，因此，當(dāng)軋件溫度的熱損失主要是熱輻射時(shí)，熱損失量與軋件溫度的4 次方成正比。

The so-called low temperature hot rolling is a rolling that is slightly higher than the recrystallization temperature. Increasing rolling temperature can reduce yield stress of workpiece and reduce deformation work. However, the deformation work can be converted into heat, so when the heat loss of the rolling temperature is mainly heat radiation, the amount of heat loss is proportional to the 4 time of the rolling temperature.

橫軋有兩種類型：一類是軋輥孔型沿軸向是不變的，沿徑向呈周期變化。軋件主要靠徑向變形實(shí)現(xiàn)成型。另一類是鍥橫軋工藝，即在兩個(gè)或者三個(gè)互相平行布置的軋輥或兩個(gè)平板的表面上.

There are two types of cross rolling: one is the roll pass is unchanged along the axis, and the other is radial variation. The workpiece is mainly formed by radial deformation. The other is the cross rolling process, that is, on the surface of two or three parallel rolls or two plates.
