圣霖国际吊车轨-圣霖国际【开拓创新】-圣霖国际吊车轨批发

轧辊的无损检测通常用超声波探伤仪进行。冷轧辊探伤标准中通常把辊身依受力情况分成表面区、中心区和中间区，圣霖国际吊车轨批发，然后依断裂力学原理分别规定各区允许存在的缺陷的临界尺寸。

Nondestructive testing of rolls is usually carried out by ultrasonic flaw detectors. In the testing standard of cold roll，圣霖国际吊车轨价格， the roll body is usually divided into the surface area，圣霖国际吊车轨经销， the center area and the middle area according to the force condition， and then the critical dimensi of the defects are allowed in each area according to the principle of fracture mechanics.

轧辊是轧机的核心部件，轧辊的使用涉及轧机使用时的类型选择、轧辊的准备、在轧制过程中的维修和周期性修整，而这些都全是影响轧机生产率、产品质量和生产经济性的因素。

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.

轧辊由辊身、辊颈和轴头二部分组成。辊颈安装在轴承中，并通过袖承座和压下装置把轧制力传给机架。铂头和连接轴相连接，传递轧制扭矩。轴头有三种主要形式；梅花轴头、万向轴头、带键槽的或圆柱形轴头。

The roll is  of two parts of the roller body，圣霖国际吊车轨， the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum， a universal shaft， or a cylindrical shaft with a keyway.
