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(tài)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.


通常對粗軋輥以強度、抗熱裂為主要要求;小型20輥軋機的工作軋輥重僅 100克左右,而寬厚板軋機的支承輥重量已超過200噸。選用軋輥時首先根據(jù)軋機對軋輥的基本強度要求,選定安全承載的主體材料(各種級別的鑄鐵、鑄鋼或鍛鋼等)。



Usually, the main requirements for rough rolling roll are strength and thermal cracking. The working roll weight of small 20 high mill is only 100 grams, while the weight of backup roll of wide plate mill has exceeded 200 t. When selecting the roll, first, according to the requirements of the mill's basic strength for the roller, we select the main material for safety loading (various grades of cast iron, cast steel or forged steel, etc.).


軋機布置和道次設計  

機架在生產(chǎn)線的位置以及道次設計對軋輥的選擇有很大影響。根據(jù)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.
