轧机设备能通过轧辊之间的相对运动，施加强大的压力，迫使金属材料发生塑性变形，所得到材料形状通常为板材，也有一些型材和毛胚采用轧制方法加工得出。
轧机有着多种分类标准，实际应用中由于材料的不同特性以及对于轧制质量的要求，轧制过程常分成冷扎和热轧；按历代轧机演变进展：传统热连轧轧机和连铸连轧机；按所需轧制成的板材厚度也有划分为中厚板轧机和中薄板轧机；按照机架分有单机架轧机，双机架轧机和多机架轧机；单按冷轧带钢生产工艺分：连续式轧机和可逆式轧机等等系列。30573
本次设计针对Ø120的窄带轧机，所谓窄带指的是本机所加工的钢材宽度在650mm以下，Ø120指轧辊直径为120mm，本轧机主要轧制小型线板材，冷轧工艺，二辊式工作机座，要求实现上下辊的异步比1.1-1.5可调节。本次设计任务要完成Ø120的窄带轧机的主机系统的设计，完成总体方案设计，完成各个传感器的安装联结设计，完成主要零部件的强度，刚度计算，设计图，装配图，总装配图与数据处理。30573

The 120 narrow rolling mill system design
ABSTRACT：Rolling mill equipment, also known as rolling machinery, simply defined as rolling machine, rolling mill, including the main equipment, auxiliary equipment, lifting transportation equipment and ancillary equipment. Generally accepted mill only contains major equipment.
Rolling mill equipment through the relative motion between the rolls and exert strong pressure, forcing the metal plastic deformation, the material shape usually sheet, employed a processing method of the rolling to the some profiles and the wool embryo to derive.
Mill has a variety of classification criteria, the practical application due to the different characteristics of the materials and requirements for the quality of rolling, rolling process is often pided into cold rolling and hot rolling; according to all previous dynasties mill process: traditional hot rolling mill and continuous casting and continuous rolling machine; according to the required thickness of rolled into also has pision for medium and heavy plate mill and plate mill; according to frame a single stand mill, two stand rolling mill and rolling mill; single according to the production technology for cold rolled strip points: continuous rolling mill and reversible rolling mill, etc. series.
The design for Ø120 narrowband mill, the so-called narrowband refers to is the machine processed steel width below the 650mm, Ø120 to roll diameter is 120mm, the mill main rolling small line plate, cold rolling process, two roller frame, implementation and asynchronous 1.1-1.5 than can be adjusted. This design task to complete o 120 narrowband mill host system design, complete the overall program design, the completion of each sensor installation and connection design, completion of the main components of the strength, stiffness calculation, design drawings, assembly drawings and assembly drawings and data processing.
