軋輥的品種和制造工藝隨冶金技術(shù)的進(jìn)步和軋鋼設(shè)備的演變而不斷發(fā)展。中世紀(jì)軋制軟的有色金屬時(shí)使用強(qiáng)度低的灰鑄鐵軋輥。18世紀(jì)中葉英國(guó)掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產(chǎn)技術(shù)。

The variety and manufacturing process of roll have been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.

軋輥按材質(zhì)主要分為哪幾種類(lèi)別？

軋輥按制造材料主要?jiǎng)澐譃殍T鋼系列軋輥、鑄鐵系列軋輥和鍛造系列軋輥三大類(lèi)別。

What are the main categories of the roll according to the material?

Rolls are mainly divided into three categories: cast steel series rolls, cast iron series rollers and forging series rolls.

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.
