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

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

按軋輥材質分有鋼軋輥、鑄鐵軋輥、硬質合金軋輥、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。各種分類可以相應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.

弄清軋輥的使用條件以及在同類型軋機中所用軋輥的失效方式，了解當前各種軋輥材質的性能和制造工藝，才能較正確地制定該軋機用輥的技術條件和選用合適而經(jīng)濟的軋輥材質。

We must know clearly the condition of the roller and the failure way of the roll used in the same type of rolling mill, and understand the performance and manufacturing technology of all kinds of roller material at present, so that we can correctly formulate the technical conditi of the roller and choose the right and economical roller material.

什么是鑄造軋輥，鑄造軋輥主要有哪些種類？

鑄造軋輥是指將冶煉鋼水或熔煉鐵水直接澆注成型這一生產(chǎn)方式制造的軋輥種類。

鑄造軋輥按材質又可分為鑄鋼軋輥和鑄鐵軋輥兩類；按制造方法又可分為整體鑄造軋輥和復合鑄造軋輥兩類。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided into two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method, it can also be divided into two types: integral casting roll and compound casting roll.
