摘 要:钢铁行业是整个工业生产发展的基础，钢铁生产对国民经济各个部门都有着重大的意义。随着社会经济进步和科技的日益发展，各企业对高质量的钢需求有所增加，同时生产钢的技术也在迅速的发展。目前，钢坯的提升设备是钢坯提升机，它保证了钢坯的连铸与连轧系统的均衡和连续性。

　　　方钢坯提升机是通过链传动把钢坯运到指定高度，从而完成下面工序。钢坯提升机广泛地运用于冶金企业钢坯的提升工作，通过输送辊道进入轧钢厂的钢坯，在进入高架式的受料辊道后再被推入加热炉，在从输送辊道到受料辊道之间近乎于垂直的提升过程中所需要一台专用机械——“钢坯提升机”来实现钢坯的垂直向上运行钢坯的提升。

　　　本次设计是对钢坯提升机的整体设计，主要是以链传动为基础，通过电机，减速器、轴以及链条、拨爪来实现钢坯的平稳提升，具有工作效率高、安全性可靠、结构简单等优点。所以本次对钢坯提升机的设计是十分必要的。

ABSTRACT:The iron and steel industry is the foundation of the development of industrial production, steel production is of major significance to the national economy each department. With the development of social economy progress and technology, each enterprise has increased demand for high quality steel, and steel production technology is in rapid development. At present, the steel billet hoist lifting equipment is of billet, it ensures the billet continuous casting and rolling system of the equilibrium and continuity.

      Billet is through the chain hoist the billet to the specified height, so as to complete the process. Billet steel billet hoisting machine widely used in metallurgical enterprise promotion work, through the roller conveyer into rolling billet, after into the overhead system of roll table being pushed into the furnace, between from comming to the roll table close to the vertical in the ascension process needs a dedicated mechanical - “billet lift” to achieve the vertical run billet steel billet. 

      The design is on the integral design of the elevator of billet, the main is based on the chain, through the motor, speed reducer, shaft and chain, dial the claw to achieve the steady improvement of steel, has high working efficiency, safety, reliable, simple structure, etc. So this design of billet hoist is very necessary.
