由于軋制過程是連續(xù)的過程，因此操作人員需要不斷檢測軋輥狀況，使生產(chǎn)出來的產(chǎn)品滿足用戶對更嚴(yán)格的公差和表面質(zhì)量的要求。

As the rolling process is a continuous process, the operator needs to continuously detect the roll status to meet the more stringent tolerance and surface quality requirements of the products produced.

生產(chǎn)長材產(chǎn)品的軋機(jī)種類繁多，因此，軋機(jī)類型的選擇、布局，軋輥材質(zhì)的選擇、軋輥尺寸的確定，選擇范圍也非常廣。同時，不同的軋機(jī)所選擇的軋輥也是不相同的，需要根據(jù)生產(chǎn)要求選擇軋輥。

There are a wide variety of rolling mills to produce long timber products. Therefore, the selection and layout of the type of rolling mill, the selection of the material of the roll and the determination of the size of the roll are also very wide. At the same time, the rolls chosen by  rolling mills are also the roller should be selected according to the production requirements.

被軋制的鋼種  

被軋制的鋼種是選擇軋輥的關(guān)鍵因素，其抗變形能力隨坯料化學(xué)成分不同而改變，主要表現(xiàn)在軋制的各階段變形的負(fù)荷大小和變化。必須根據(jù)確定的強(qiáng)度和硬度選擇軋輥。  

Rolled steel

The rolled steel is the key factor to select the roll. Its deformation resistance varies with the chemical  of the billet. It is mainly manifested in the load and change of deformation in each rolling stage. The roll must be selected according to the determined strength and hardness.
