軋機(jī)上使金屬產(chǎn)生連續(xù)塑性變形的主要工作部件和工具。軋輥主要由輥身、輥頸和軸頭3部分組成。

輥身是實(shí)際參與軋制金屬的軋輥中間部分。它具有光滑的圓柱形或帶軋槽的表面。輥頸安裝在軸承中，并通過軸承座和壓下裝置把軋制力傳給機(jī)架。

The roller body is the middle part of the roll that actually takes part in rolling the metal. It has a smooth cylinder or a surface with a groove. The roller neck is installed in the bearing and passes the rolling force to the rack through the bearing seat and the press down device. .

軋輥在軋機(jī)中的使用效果不但取決于軋輥材質(zhì)及其冶金質(zhì)量，還和使用條件、軋輥設(shè)計(jì)、操作維護(hù)有關(guān)。不同類型軋機(jī)的軋輥使用條件有很大差異，造成差異的因素有：軋機(jī)條件。如軋機(jī)類型、軋機(jī)和軋輥設(shè)計(jì)、孔型設(shè)計(jì)、水冷條件和軸承種類等。

The use effect of roll in the rolling mill not only depends on the material and metallurgical quality of the roll, but also is related to the conditi of use, the design of the roll and the operation and maintenance. The use conditi of the rolls for different types of rolling mills are very different. The factors that cause the difference are the rolling mill conditi. Such as rolling mill type, rolling mill and roll design, pass design, water cooling condition and bearing type and so on.

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(zhì)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(fù)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.
