按轧辊材质分有钢轧辊、铸铁轧辊、硬质合金轧辊、陶瓷轧辊等;按制造方法分有铸造轧辊、锻造轧辊、堆焊轧辊、镶套轧辊等;按所轧钢材状态分有热轧辊、冷轧辊。各种分类可以相应组合而使轧辊有更明确的含义,如热轧带钢用离心铸造高铬铸铁工作辊。
According to the roller material, there are steel rolls, cast iron rolls, hard alloy rolls, ceramic rollers, etc. according to the manufacturing method, there are casting rolls, forging rolls, hardfacing rolls, inlaid rolls and so on. According to the rolled steel status, there are hot rollers and cold rollers. Various classificati*** can be combined to make the roll more explicit, such as the casting of high chromium cast iron working roll for hot rolled strip.
(1)堆焊前需先将轧辊辊身表面的疲劳层或缺陷,尤其是裂纹必须彻底清除;
(2)在堆焊时,为了防止裂纹的产生,必须先加工轧辊辊身预热,预热温度根据轧辊辊及堆焊材料而定。
(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.
轧机布置和道次设计
机架在生产线的位置以及道次设计对轧辊的选择有很大影响。根据机架位置,轧辊的受力方式和性能可以有很大变化。这是因为应用于粗轧机架和精轧机架的轧辊有非常不同的受力方式,从而导致轧辊性能有预期的改变.
Rolling mill layout and pass design
The of the rack in the production line and the design of the pass h***e 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 h***e very different forces, resulting in expected changes in roll performance.
