冷轧板带轧辊的辊身呈微凸,当它受力弯曲时可保证良好扳形;型钢轧机轧辊的辊身上有轧槽,根据型钢轧制工艺要求,安排孔型。钢管轧制中采用斜轧原理轧制的轧辊有圆锥形、腰鼓形或盘形。
The roll body of the cold rolled strip roller is slightly convex. When it is bent by force, it can ensure good shape. There are grooves on the roller body of the section mill roll, and the pass is arranged according to the rolling requirements of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.
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, 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.
不同类型的轧机以及同类型而使用条件不同的轧机,对所用的轧辊性能要求不尽雷同,如方坯和板坯初轧机轧辊要具有好的扭转和弯曲强度、韧性、咬入性、抗热裂性和热冲击性以及耐磨性;So,ononehandcanmaketherollerstressheattreatmentshopallocationhookare。而热带精轧机架要求轧辊辊面的高硬度、抗压痕、耐磨、抗剥落和耐热裂等性能。
Different types of rolling mill and the same type and the use of different conditi on properties of roll mill, requirements for not identical, such as billet and slab mill roll with good torsional and bending strength, toughness, bite, thermal cracking resistance and thermal shock resistance and abrasion resistance; tropical finishing stand requirements the roller surface hardness, wear resistance, spalling resistance, indentation resistance and thermal cracking performance.
这些应力沿辊身的散布是不均匀的、不断改变的,其原因不只有规划要素,还有轧辊在运用中磨损、温度和辊形的不断改变。
The dispersion of these stresses along the roll is uneven and ctantly changing, and the reas are not only the planning elements, but also the ctant change of wear, temperature and roll shape in the use of the rolls.
