軋輥采購(gòu)服務(wù)放心可靠【圣霖國(guó)際】

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(guò)渡層進(jìn)行預(yù)先堆焊過(guò)渡層。同時(shí)，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。  

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.

初軋機(jī)、鋼坯連軋機(jī)、大型型鋼和軌梁軋機(jī)、熱軋板帶鋼軋機(jī)破鱗和軋邊機(jī)、型鋼軋機(jī)的軋邊機(jī)，還有小型型鋼、線棒材軋機(jī)的粗軋機(jī)架等軋機(jī)使用的軋輥，大多采用整體鑄造方法生產(chǎn)，這類軋輥使用層較厚，孔型較深。

The rolling mill of rolling mill, billet rolling mill, large type steel and rail beam mill, hot rolled strip mill break scale, rolling edge mill, type steel universal mill, and rolling mill used in small steel and wire rod mill are mostly produced by the whole casting method, which is thicker and deeper.

軋機(jī)布置和道次設(shè)計(jì)  

機(jī)架在生產(chǎn)線的位置以及道次設(shè)計(jì)對(duì)軋輥的選擇有很大影響。根據(jù)機(jī)架位置，軋輥的受力方式和性能可以有很大變化。這是因?yàn)閼?yīng)用于粗軋機(jī)架和精軋機(jī)架的軋輥有非常不同的受力方式，從而導(dǎo)致軋輥性能有預(yù)期的改變.

Rolling mill layout and pass design

The of the rack in the production line and the design of the pass have great influence on the choice of the roll. According to the  of the frame, the force and performance of the roller can be greatly changed. This ibecause the rolls used in roughing mill stand and finishing mill stand have very different forces, resulting in expected changes in roll performance.
