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.

整體軋輥是相對(duì)于復(fù)合軋輥而言的，整體軋輥的輥身外層與心部以及輥頸采用單一材質(zhì)鑄造或鍛造而成，輥身外層和輥頸不同的組織、性能通過(guò)鑄造或鍛造工藝以及熱處理工藝過(guò)程來(lái)控制和調(diào)整。

The whole roll is compared to the  roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are  and adjusted by the casting or forging process and the heat treatment process.

在粗軋機(jī)架后，中型型材軋機(jī)有兩組連續(xù)的機(jī)架。連續(xù)軋機(jī)，根據(jù)孔型設(shè)計(jì)既可以水平布置，也可以立式布置。對(duì)于有平行緣的型鋼和槽鋼，還配有機(jī)架。

After the roughing mill, there are two sets of continuous rack in the medium section mill. The continuous rolling mill can be arranged horizontally or vertically according to the pass design. For steel and channel steel with parallel edges, universal frame is also available.
