摘 要: 通过现场工业实验，初步确定了高压辊磨机结构的非对称性是设备运行时两工作压辊功耗产生较大差异的主要原因，进而通过建立高压辊磨机的动力学模型，从理论上分析了设备结构非对称性对两压辊功耗差异的影响规律。计算机仿真结果表明：高压辊磨机结构的非对称引起两压辊不同的动态特性，是导致其功耗差异的主要原因。

Abstract:Production investigation was made to initially verify the main reason of power difference between the two rollers of high-pressure rolling mill. Furthermore the dynamic mechanical model for high-pressure rolling mill was built up and the effect of the non-symmetrical roller structure on the power difference was theoretically analyzed. Experimental and computer-imitated results show that non-symmetrical structure of the roller, which results different dynamic characteristics in the two rollers, is the main reason of power difference between the two rollers of high-pressure rolling mill.
Key words: high-pressure rolling mills; power; non-symmetric roller
