初轧机打滑的危害性
HARMFULNESS OF ROLL SLIPPAGE ON BLOOMING MILL
【摘要】 本文论述了初轧机在轧制过程中打滑引起的两种不同的扭振响应。根据扁头断口上的疲劳裂纹用断裂力学的方法计算出断裂扭矩,与上述两种扭振响应能相吻合,从而对这次断裂事故原因作出了科学分析。
【Abstract】 This paper discusses two kinds of torsional vibration response produced in driving systemof blooming mill owing to the roll slippage in operation.By means of fracture mechanics we ca-lculated the fracture torque according to the cracks appeared in damaged section of the wobbler.The calculated fracture torque is in accordance with two kinds of torsional vibration response,therefore this paper gives a scientific analysis for this damaged event of the blooming mill.
