軋輥生產(chǎn)廠家優(yōu)選商家“本信息長期有效”

軋輥由輥身、輥頸和軸頭二部分組成。輥頸安裝在軸承中,并通過袖承座和壓下裝置把軋制力傳給機(jī)架。鉑頭和連接軸相連接,傳遞軋制扭矩。軸頭有三種主要形式;梅花軸頭、萬向軸頭、帶鍵槽的或圓柱形軸頭。



The roll is  of two parts of the roller body, the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum, a universal shaft, or a cylindrical shaft with a keyway.


軋輥的品種和制造工藝隨冶金技術(shù)的進(jìn)步和軋鋼設(shè)備的演變而不斷發(fā)展。中世紀(jì)軋制軟的有色金屬時(shí)使用強(qiáng)度低的灰鑄鐵軋輥。18世紀(jì)中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產(chǎn)技術(shù)。

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.


軋輥的無損檢測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.


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.
