由于轧制过程是连续的过程,因此操作人员需要不断检测轧辊状况,使生产出来的产品满足用户对更严格的公差和表面质量的要求。
As the rolling process is a continuous process, the operator needs to continuously detect the roll status to meet the more stringent tolerance and surface re of the products produced.
焊接时堆焊成败的关键环节,要获得理想的堆焊层必须综合考虑某些可变因素,crane rail厂家,如:焊接电压、焊接速度、轧辊转速、轧辊的保温、焊接电流、焊接材料等,对一些含碳及合金元素高的辊芯,为防止脆性区的裂纹,除一定的预热措施外,多采用低碳低合金过渡层进行预先堆焊过渡层。
In order to obtain an ideal surfacing layer, some variable factors must be considered, such as welding voltage, welding speed, roll speed,crane rail生产厂家, 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 considered in order to obtain ideal surfacing layer. In addition,锦州crane rail, the low carbon low alloy transition layer is used to pre weld the transition layer.
实践表明,带双镀槽的轴头在使用过程中,镶槽壁容易崩裂,目前常用易加工的带平台的袖头代替双因槽的抽头。
直径超过400mm的冷轧轧辊,在锻造后,多半在中心馒一个670一250mm的通7L。这样,一力面可以使轧辊经热处理店的内应力分朽均勾;另一方面在轧辊表面淬火时,可对轧辊通水冷却,提高淬火效果。
Practice shows that, with double bath head is in use, insert groove wall is easy to crack, at present common processing platform with the cuff instead of double slot for tap.
Cold roll diameter of more than 400mm,crane rail生产, after forging, mostly in the 7L center. A 670 250mm. So, on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand, the roll surface , the water cooling roller, improve the effect.
