剥落、粘辊和裂纹是冷轧工作辊失效的重要原因之一。武钢一米七冷轧机和单、双平整机是从西德引进的现代化轧机,其轧制压力最大可达到2500吨,轧制速度可达30米/秒。由于冷轧辊在轧制过程中经受复杂的应力作用和各种事故的考验,所以其失效形式亦各不相同。 Spalling, sticking rolls and cracks are one of the important reasons for the failure of cold work rolls. Wuhan Iron and seven meters cold rolling mill and single, double flat machine is the introduction of modern West Germany from the rolling mill, the rolling pressure up to 2500 tons, the rolling speed of up to 30 m / s. As the cold roll in the rolling process to withstand complex stress tests and a variety of accidents, so the failure forms are also different.
