圆管坯弧形连铸机拉矫机力能参数计算初探

AN APPROACH TO CALCULATING THE PROCESS PARAMETERS OF THE WITHDREWING & STRAIGHTENING SYSTEM IN AN ARC CC MACHINE FOR ROUND BILLETS

分析并计算了弧形连铸圆管坯多点拉矫机的拉坯阻力、矫直力矩、矫直力和形变率,并揭示了多点拉矫时的剪切力,形变率和形变速度与铸坯矫直质量之间的关系,介绍了多点拉矫机的工作性能,为连铸机的选型和设计提供了参考依据。

Withdrew resistance, straightening, torque, straightening force and formation rate of the multipoint withdrewing & straightening system of an arc CC machine for round billets are analyzed and calculated, the relationship between shear force, formation rate, formation speed durig during multipoint withdrewing & straightening and billet quality after straightening as well as performances of the system are also described,which provided a reference for selection and desing of a CC machine.
