杭钢对500轧机前后工作辊道和热剪前输送辊道进行了更新,在结构上作了较大改进。几年来的生产实践表明,取得了明显的经济效果,提高了辊道的工作可靠性,延长了各零件的使用寿命。装拆和调整简便,维修时间大大缩短。本文阐述了更新后的辊子结构;传动轴的装配;辊简参数和结构;辊道的支架与基础等。 Hangzhou Iron and Steel 500 mill before and after the work roll and hot shear roller conveyor before the update, made significant structural improvements. Over the past few years of production practice shows that achieved significant economic results, improve the reliability of roller work, extending the life of the parts. Assembly and disassembly and adjustment easy, greatly reducing maintenance time. This article describes the updated roller structure; assembly of the drive shaft; roller profile and structure; roller support and foundation.
