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.

修正精度高，涂層厚度從幾微米到幾毫米，可對(duì)金屬工件呈現(xiàn)磨損、劃傷、、裂紋、破損變形、硬度降低、損害等缺點(diǎn)進(jìn)行堆積、封孔、補(bǔ)對(duì)等修正功用，只須打磨、拋光，也可進(jìn)行車、銑、 刨、磨等各類機(jī)械加工，以及電鍍等后期加工。

The thickness of the coating is high, and the thickness of the coating is from several microns to a few millimeters. It can be worn, scratched, pinholes, cracks, breakage and deformation, hardness reduction, damage and other shortcomings to accumulate, seal, and compensate for the defects, such as grinding, polishing, milling, milling, grinding and other kinds of mechanical processing, as well as electroplating later processing.

軋輥是軋機(jī)的核心部件，軋輥的使用涉及軋機(jī)使用時(shí)的類型選擇、軋輥的準(zhǔn)備、在軋制過程中的維修和周期性修整，而這些都全是影響軋機(jī)生產(chǎn)率、產(chǎn)品質(zhì)量和生產(chǎn)經(jīng)濟(jì)性的因素。

Roll is the core part of the rolling mill. The use of the roll involves the type selection of the rolling mill, the preparation of the roll, the maintenance and the periodic dressing during the rolling process, all of which are all factors that affect the productivity of the rolling mill, the quality of the product and the production economy.

焊接時(shí)堆焊成敗的關(guān)鍵環(huán)節(jié)，要獲得理想的堆焊層必須綜合考慮某些可變因素，如：焊接電壓、焊接速度、軋輥轉(zhuǎn)速、軋輥的保溫、焊接電流、焊接材料等，對(duì)一些含碳及合金元素高的輥芯，為防止脆性區(qū)的裂紋，除一定的預(yù)熱措施外，多采用低碳低合金過渡層進(jìn)行預(yù)先堆焊過渡層。So,ononehandcanmaketherollerstressheattreatmentshopallocationhookare。  

In order to obtain an ideal surfacing layer, some variable factors must be cidered, such as welding voltage, welding speed, roll speed, roll insulation, welding current, welding material and so on. Some roll cores with high carbon and alloy elements, in order to prevent cracks in brittle zone, have to be cidered in order to obtain ideal surfacing layer. In addition, the low carbon low alloy transition layer is used to pre weld the transition layer.
