毕业论文机架辊

Broadband hot-rolled steel is an important iron and steel industry of steel varieties, production technology and equipment level, the level of the entire steel industry's technological progress and economic efficiency has an important influence, also shows that the iron and steel industry of a country's level of development. This design is the production of hot-rolled against the leading broadband by 2050 hot-rolled steel finishing mill on the plane. According to 2050 data of the hot rolling mill (Baosteel 2050 hot rolling mill finishing mill work-Block) hot rolling mill of four roll-on the selection and design of the structure, including the completion of strip hot rolling mill for work at the structure, Component design; Roller roller bearings and design; balance (pinched) and roll bending device design work roll teloping design; rack role, structure and characteristics of the design. In the design process in detail to find relevant information and by the use of the method and theory, analysis and design work for hot strip mill at the structure and ultimately successful completion of graduate design. Key words: Roll and Roll bearing, balance and roll bending device, rack

热轧宽带钢这词很专业。我得好好查查。主要是分太少，都没心情查了。建议楼住还是机译吧。

采煤机？挖掘机？

机架辊是最靠近轧机轧辊的几根单独驱动的工作辊道。由于轧机机架（轧机牌坊）尺寸较大，远大于轧辊的直径，所以将该辊道安装在轧钢机机架上（否则会造成辊道和轧辊距离太远，会影响轧制），故称为机架辊。机架辊经常受到轧件抛出时产生的冲击，电机和传动轴易损。机架辊的速度与轧辊完全匹配，主要作用是帮助轧件顺利咬入到轧机辊缝中。机架辊：用于安装轧辊轴承座和轧辊调整装置并承受轧制力的工作机座的框架。
