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.


修正精度高,涂層厚度從幾微米到幾毫米,可對(duì)金屬工件呈現(xiàn)磨損、劃傷、、裂紋、破損變形、硬度降低、損害等缺點(diǎn)進(jìn)行堆積、封孔、補(bǔ)對(duì)等修正功用,只須打磨、拋光,也可進(jìn)行車、銑、 刨、磨等各類機(jī)械加工,以及電鍍等后期加工。

The thickness of the coating is high, and the thickness of the coating is from several microns to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation, hardness reduction, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.


軋輥的無損檢測(cè)通常用超聲波探傷儀進(jìn)行。冷軋輥探傷標(biāo)準(zhǔn)中通常把輥身依受力情況分成表面區(qū)、中心區(qū)和中間區(qū),然后依斷裂力學(xué)原理分別規(guī)定各區(qū)允許存在的缺陷的臨界尺寸。



Nondestructive testing of rolls is usually carried out by ultrasonic flaw detectors. In the testing standard of cold roll, the roll body is usually divided into the surface area, the center area and the middle area according to the force condition, and then the critical dimensi of the defects are allowed in each area according to the principle of fracture mechanics.
