High heat treatment performance of roller sleeve (1), uniform hardness, reasonable hardness gradient, thus ensure the long service life of inlaid backup roller.
辊套(1)的热处理性能好,硬度均匀,硬度梯度从表面层向芯部下降梯度小。因此镶套支承辊的使用寿命长。
Four-row roller bearings on the working rolls mainly bear roll-bending force and axial force, while the oil film on the backup roll mainly bear rolling force and most of the bending moment.
工作辊上的四列滚子轴承主要承受弯辊力和轴向力,而支撑辊上的油膜轴承主要承受轧制力和绝大部分弯曲力矩。
