摘要
四辊轧机下支承辊总成的止推轴承破碎事故和油膜轴承进水事故,对热轧薄板的正常生产已构成了突出威胁。本文从研究该总成的稳定性和动力学模型入手,对事故的机理进行了分析并提出对策。
Accidents about the broken down of the thrust bearing and infiltration of water in- to the oil film bearing at the lower backup roll of the 4-high mill have constituted severe threats on the regular production of the hot rolled strip.Starting from studies on the stability and dynamic mod- el of the assembly the present paper analyzed the mechanism of the accidents and offered counter measures
