摘　　要：传统支承辊表淬用吊卡头需在辊颈额外增加余量,且需镗孔。改进后的吊卡头无需增加余量,直接车床加工,操作安全可靠。Lifting head used for surface quenching of traditional backup roll is needed to increase allowance on journal and bore a hole. The improved lifting head isn＇t needed to increase allowance and can be machined directly on lathe and can be operated safely and stably.

关 键 词：支承辊 吊卡头 结构改进
