(1)軟輥；肖氏硬度約為30一40，用于開坯機、大型型鋼軋機的租軋機等。

(2)半硬輥：肖氏硬度約為40一60，用于大型、中型、小型型鋼軋機和鋼板輪機的租軋機。

(3)硬面輥：肖氏硬度約為60一85，用于薄板、中板、中型型鋼和小型型鋼軋機的稿軋機及四輥軋機的支撐輥。

(4)特硬輥le氏硬度約為85—100，用于冷軋機。

(1) soft roll; the hardness of Shaw is about 30 40. It is used for the renting rolling mill of the billet machine and the large steel mill.

(2) semi hard roll: the hardness of the Shaw is about 40 to 60. It is used for the renting rolling mill of large, medium, small type steel mill and steel plate turbine.

(3) hard roll: Shore hardness of about 60 to 85, for supporting roller mill release sheet, plate, medium and small steel mill and four roller mill.

(4) the hardness of the hard roll Le is about 85 - 100 for cold rolling mill.

軋輥的品種和制造工藝隨冶金技術(shù)的進步和軋鋼設(shè)備的演變而不斷發(fā)展。中世紀(jì)軋制軟的有色金屬時使用強度低的灰鑄鐵軋輥。18世紀(jì)中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產(chǎn)技術(shù)。

The variety and manufacturing process of roll have been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.

而精軋輥速度較高，軋制終產(chǎn)品要有一定的表面質(zhì)量，對它以硬度、耐磨等為主要要求。然后考慮軋輥使用時所應(yīng)有的耐磨性。由于軋輥的磨損機理很復(fù)雜，包括機械應(yīng)力作用、軋制時的熱作用、冷卻作用、潤滑介質(zhì)的化學(xué)作用以及其他作用。

And the high speed of the fine roller, the final product of rolling must have a certain surface quality, which is the main requirement for its hardness, wear resistance and so on. Then the wear resistance should be cidered when the roll is used. Because the wear mechanism of roller is very complicated, including mechanical stress, thermal action during rolling, cooling effect, chemical action of lubricating medium and other functi.

當(dāng)軋制其它型材時，可以用水平機架更換機架。水平機架的軋輥有很深的孔型，而機架沒有。  

較大直徑的水平軋輥確定型鋼的的形狀，而較小直徑的一對立輥用于軋制邊部。當(dāng)坯料穿過傳統(tǒng)機架和機架精軋軋輥時，可以獲得很好的表面光潔度和尺寸公差。  

When rolling other profiles, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.

Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with smaller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
