(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的進步和軋鋼設備的演變而不斷發(fā)展。中世紀軋制軟的有色金屬時使用強度低的灰鑄鐵軋輥。18世紀中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產技術。

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.

既避免機械加工，又無補焊熱應力熱影響，修正厚度也不受捆綁，一起產品所具有的耐磨性及金屬材料不具備的退讓性，確保修正部位的接觸協(xié)作。

Not only to avoid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not available, so as to ensure a hundred percent contact and cooperation of the corrected parts.
