軋輥是軋機(jī)的重要部件，按照軋機(jī)類型可分為領(lǐng)帶軋機(jī)軋輥、型鋼輪機(jī)扎輥和鋼管軋機(jī)軋輥三大類。

板帶軋機(jī)軋輥的輥身呈圓柱形，熱乾板帶軋輥的輥身微凹，當(dāng)受熱膨脹時(shí)，可保持較好的扳形。

Roll is an important part of the rolling mill. According to the type of rolling mill, it can be divided into three types: the tie mill roll, the type steel turbine ligation roll and the steel tube rolling mill roll.

The roll body of a strip rolling mill is cylindrical, and the roll body of the hot dry plate is slightly concave. When the heat is expanded, it can maintain a better shape.

常用的軋輥材質(zhì)和用途見表。軋輥的性能和質(zhì)量一般取決于其化學(xué)成分和制造方式并可由其組織、物理和力學(xué)性能以及存在于軋輥內(nèi)部的殘余應(yīng)力類型來(lái)評(píng)估（見軋輥檢驗(yàn)）。

The material and use of the commonly used rolls are shown in the table. The performance and quality of roller generally depend on its chemical  and manufacturing way, and can be evaluated by its organization, physical and mechanical properties and the type of residual stress existing inside the roll (see roll test).

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.
