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(jié)合的換輥方式，導(dǎo)衛(wèi)橫梁安裝在軋機(jī)軸承座上，更換軋輥時,導(dǎo)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(jī)架是軋鋼機(jī)的主要部件，它在軋鋼過程中承擔(dān)金屬變形給予的負(fù)荷。因此要求機(jī)架有足夠的強(qiáng)度和剛度，以保證設(shè)備安全和產(chǎn)品質(zhì)量。型鋼軋機(jī)的機(jī)架形式較多，常見的機(jī)架形式有開口式機(jī)架、閉口式機(jī)架和半閉口式機(jī)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(jī)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(shè)備的主要優(yōu)點(diǎn)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(jī)進(jìn)行分類的時候，一般是按照軋輥的排列和數(shù)目進(jìn)行分類。下面我們就來了解下具體的內(nèi)容。比如二輥軋機(jī)，其的主要特點(diǎn)就是結(jié)構(gòu)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.
