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.

機架是軋鋼機的主要部件，它在軋鋼過程中承擔金屬變形給予的負荷。因此要求機架有足夠的強度和剛度，以保證設備安全和產(chǎn)品質量。型鋼軋機的機架形式較多，常見的機架形式有開口式機架、閉口式機架和半閉口式機架3種。

The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to have sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.

四棍軋機的工作輥直徑較小，傳遞軋制力矩，軋延壓力由直徑較大的支承輥承受。這類設備的主要優(yōu)點是相對剛度較大，壓下量大、軋延力小，可軋制較薄的板材，也包括有可逆和連軋兩種。

The working roll diameter of the four bar mill is small, and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness, large reduction, low rolling force, thin rolled sheets, and reversible and continuous rolling two.

在對軋機進行分類的時候，一般是按照軋輥的排列和數(shù)目進行分類。下面我們就來了解下具體的內容。比如二輥軋機，其的主要特點就是結構簡單、用途廣泛，也包括可逆式和不可逆式兩種。

When classifying rolling mills, they are generally classified according to the number and arrangement of rolls. Next we will find out the specific content. For example, two-high mill, its main features are simple structure, wide range of uses, including reversible and irreversible two kinds.
