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.

實(shí)踐表明，帶雙鍍槽的軸頭在使用過(guò)程中，鑲槽壁容易崩裂，目前常用易加工的帶平臺(tái)的袖頭代替雙因槽的抽頭。

直徑超過(guò)400mm的冷軋軋輥，在鍛造后，多半在中心饅一個(gè)670一250mm的通7L。這樣，一力面可以使軋輥經(jīng)熱處理店的內(nèi)應(yīng)力分朽均勾；另一方面在軋輥表面淬火時(shí)，可對(duì)軋輥通水冷卻，提高淬火效果。

Practice shows that, with double bath head is in use, insert groove wall is easy to crack, at present common processing platform with the cuff instead of double slot for tap.

Cold roll diameter of more than 400mm, after forging, mostly in the 7L center. A 670 250mm. So, on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand, the roll surface quenching, the water cooling roller, improve the quenching effect.

冷軋輥在工作過(guò)程中要承受很大的軋制應(yīng)力，加上軋件的焊縫、夾雜、邊裂等問(wèn)題，容易導(dǎo)致瞬間高溫，使工作輥受到強(qiáng)烈熱沖擊，造成裂紋、粘輥、剝落甚至報(bào)廢。軋輥是軋機(jī)的核心部件，軋輥的使用涉及軋機(jī)使用時(shí)的類(lèi)型選擇、軋輥的準(zhǔn)備、在軋制過(guò)程中的維修和周期性修整，而這些都全是影響軋機(jī)生產(chǎn)率、產(chǎn)品質(zhì)量和生產(chǎn)經(jīng)濟(jì)性的因素。因此，冷軋輥要有抵抗因彎曲應(yīng)力、扭轉(zhuǎn)應(yīng)力、剪切應(yīng)力引起的開(kāi)裂和剝落的能力，同時(shí)也要有高的耐磨性。

Cold roll must bear a lot of rolling stress in the working process, add the weld, inclusion and edge crack of the rolled piece, which can easily lead to instantaneous high temperature, so that the work roll is subjected to strong heat shock, which causes crack, roll, peeling and even scrap. Therefore, the cold roller must resist the ability of cracking and spalling caused by bending stress, torsional stress and shearing stress, and also has high wear resistance.
