圣霖國際吊車軌廠家優(yōu)選企業(yè)【圣霖國際】

修正精度高，涂層厚度從幾微米到幾毫米，可對金屬工件呈現(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.

（1）堆焊前需先將軋輥輥身表面的疲勞層或缺陷，尤其是裂紋必須徹底清除；  

（2）在堆焊時，為了防止裂紋的產(chǎn)生，必須先加工軋輥輥身預(yù)熱，預(yù)熱溫度根據(jù)軋輥輥及堆焊材料而定。

(1) before welding, the fatigue layer or defect of the roller body surface must be first removed, especially the crack must be thoroughly removed.

(2) in the process of surfacing, in order to prevent cracks, the roller body must be pre heated, and the preheating temperature should be determined according to roll rolls and surfacing materials.

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.
