機架是軋鋼機的主要部件，它在軋鋼過程中承擔(dān)金屬變形給予的負(fù)荷。因此要求機架有足夠的強度和剛度，以保證設(shè)備安全和產(chǎn)品質(zhì)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.

實現(xiàn)金屬軋制過程的設(shè)備。泛指完成軋材生產(chǎn)全過程的裝備，包括有主要設(shè)備、輔助設(shè)備、起重運輸設(shè)備和附屬設(shè)備等。但一般所說的軋機往往僅指主要設(shè)備。

A device for a metal rolling process. Generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. Generally speaking, rolling mills usually refer to only the main equipments.

據(jù)說在14世紀(jì)歐洲就有軋機，但有記載的是1480年意大利人達(dá)·芬奇（Leonardo da Vinci）設(shè)計出軋機的草圖。1553年法國人布律列爾(Brulier)軋制出金和銀板材,用以制造錢幣。此后在西班牙、比利時和英國相繼出現(xiàn)軋機。

It is said that there are rolling mills in Europe in the fourteenth Century, but it is recorded that in 1480, Leonardo Da Vinci (Italian Italian designer Da Finch) designed the draft for rolling mills. In 1553 the French law Adler cloth (Brulier) rolled gold and silver plate, used in the manufacture of coins. Since then, rolling mills have been rolled out in Spain, Belgium and Britain.
