为适应轧制生产的现代化,轧机的换辊装置近些年来有了很大的发展。特别是对于二辊轧机和四辊轧机,已经设计出了多种型式的快速换辊装置,这对于缩短换辊时间,减少劳动强度,提高生产效率无疑都是十分有利的。对于具体轧机,不管是新设计或是改造设计,到底采用什么样的换辊方式,都必须具体分析,把各种方案做综合比较才能做出合理的选择。一般说来应重点考虑以下几方 In order to adapt to the modernization of the rolling mill, the roll changing device of the rolling mill has been greatly developed in recent years. Especially for two-roll mills and four-roll mills, many types of rapid roll changers have been designed, which are undoubtedly advantageous for shortening the roll changing time, reducing labor intensity and increasing the production efficiency. For a specific mill, whether it is a new design or design, in the end what kind of roll change, must be a specific analysis of the various programs to make a comprehensive comparison to make a reasonable choice. In general, the following aspects should be considered
