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.
整體軋輥是相對(duì)于復(fù)合軋輥而言的,整體軋輥的輥身外層與心部以及輥頸采用單一材質(zhì)鑄造或鍛造而成,輥身外層和輥頸不同的組織、性能通過鑄造或鍛造工藝以及熱處理工藝過程來控制和調(diào)整。
The whole roll is compared to the roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are and adjusted by the casting or forging process and the heat treatment process.
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.
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(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。
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.
