冷軋板帶軋輥的輥身呈微凸,當(dāng)它受力彎曲時(shí)可保證良好扳形;型鋼軋機(jī)軋輥的輥身上有軋槽,根據(jù)型鋼軋制工藝要求,安排孔型。鋼管軋制中采用斜軋?jiān)碥堉频能堓佊袌A錐形、腰鼓形或盤(pán)形。
The roll body of the cold rolled strip roller is slightly convex. When it is bent by force, it can ensure good shape. There are grooves on the roller body of the section mill roll, and the pass is arranged according to the rolling requirements of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.
軋輥中大量使用合金元素是在第二次以后,這是軋鋼設(shè)備朝著大型化、連續(xù)化、高速化、自動(dòng)化發(fā)展以及軋材強(qiáng)度提高、變形抗力加大后對(duì)軋輥性能提出更高要求的結(jié)果。
A large number of alloying elements in the rolls are produced after the Second World War.the result of rolling mill's large performance, continuous, high-speed and automatic development, as well as the increase of rolling strength and resistance to deformation.
按軋輥材質(zhì)分有鋼軋輥、鑄鐵軋輥、硬質(zhì)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(lèi)可以相應(yīng)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.
軋機(jī)布置和道次設(shè)計(jì)
機(jī)架在生產(chǎn)線的位置以及道次設(shè)計(jì)對(duì)軋輥的選擇有很大影響。根據(jù)機(jī)架位置,軋輥的受力方式和性能可以有很大變化。這是因?yàn)閼?yīng)用于粗軋機(jī)架和精軋機(jī)架的軋輥有非常不同的受力方式,從而導(dǎo)致軋輥性能有預(yù)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.
