              按軋輥材質分有鋼軋輥、鑄鐵軋輥、硬質合金軋輥、陶瓷軋輥等;按制造方法分有鑄造軋輥、鍛造軋輥、堆焊軋輥、鑲套軋輥等;按所軋鋼材狀態分有熱軋輥、冷軋輥。各種分類可以相應組合而使軋輥有更明確的含義,如熱軋帶鋼用離心鑄造高鉻鑄鐵工作輥。



              According to the roller material, there are steel rolls, cast iron rolls, hard alloy rolls, ceramic rollers, etc. according to the manufacturing method, there are casting rolls, forging rolls, hardfacing rolls, inlaid rolls and so on. According to the rolled steel status, there are hot rollers and cold rollers. Various classificati can be combined to make the roll more explicit, such as the casting of high chromium cast iron working roll for hot rolled strip.


              初軋機、鋼坯連軋機、大型型鋼和軌梁軋機、熱軋板帶鋼軋機破鱗和軋邊機、型鋼軋機的軋邊機,還有小型型鋼、線棒材軋機的粗軋機架等軋機使用的軋輥,大多采用整體鑄造方法生產,這類軋輥使用層較厚,孔型較深。



              The rolling mill of rolling mill, billet rolling mill, large type steel and rail beam mill, hot rolled strip mill break scale, rolling edge mill, type steel universal mill, and rolling mill used in small steel and wire rod mill are mostly produced by the whole casting method, which is thicker and deeper.


              軋機布置和道次設計  

              機架在生產線的位置以及道次設計對軋輥的選擇有很大影響。根據機架位置,軋輥的受力方式和性能可以有很大變化。這是因為應用于粗軋機架和精軋機架的軋輥有非常不同的受力方式,從而導致軋輥性能有預期的改變.



              Rolling mill layout and pass design

              The of the rack in the production line and the design of the pass have great influence on the choice of the roll. According to the  of the frame, the force and performance of the roller can be greatly changed. This ibecause the rolls used in roughing mill stand and finishing mill stand have very different forces, resulting in expected changes in roll performance.
