由于某规格异型钢在粗轧阶段某异型孔咬入过程中发生偏转,给轧件成形及稳定轧制造成不利影响。借助有限元分析软件对轧制过程进行模拟分析,并对咬入过程进行分阶段研究,确定轧件偏转原因主要是由于轧件上翼缘左侧首先与上辊形成单点接触,造成轧件咬入失稳,从而产生偏转。对孔型进行优化并进行模拟验证,改进的孔型用于生产,实现了稳定咬入,保证轧制顺行。 As a special-shaped steel in the roughing stage of a shaped hole bite into the process of deflection, the rolling forming and stable rolling adversely affected. The finite element analysis software was used to simulate the rolling process and to study the bite-in process in stages. The reason for the deflection of the rolling stock was determined mainly because the left side of the flange of the rolling stock first formed a single point contact with the upper roll, Biting into instability, resulting in deflection. The hole is optimized and simulated, the improved hole for production, to achieve a stable biting, to ensure the smooth rolling.
