摘要
钢包回转台设在连铸机浇铸位置上方用于运载钢包过跨和支承钢包进行浇铸的设备,是现代连铸生产中的重要设备之一,为实现连铸创造了连续提供钢液的条件。
钢包回转台有四个工作特点:
1 它能迅速准确的将载满钢水的钢包运送至浇钢位置,并在浇钢过程中支承钢包;
2 更换钢包迅速、能适应多炉连浇的需要;发生事故或断电时,能迅速将钢包移至安全位置;
3 能实现保护浇注,并通过安装钢水称重装置,浇注更顺利;
4 占用浇铸平台面积小,有利于浇注操作。
本课设计以SMS公司设计生产的蝶式可升降钢包回转台为参照。主要对回转装置进行相关设计计算,设计包括计算驱动装置功率和电机选型校核、减速器的选型、开式齿轮校核、回转支承的选型和地脚螺栓的校核等。

Abstract
Ladle turret position in continuous casting machine casting ladle over the top for the delivery and support across the ladle for casting equipment, is important in the production of modern casting one of the devices, in order to achieve the creation of a continuous casting of molten steel to provide the conditions.
Ladle turret has four work characteristics:
It will quickly and accurately ladle full of molten steel pouring position transported to and support the process of pouring steel ladle.
Replacement Ladle quickly able to adapt to the needs of multi-continuous casting furnace;accident or a power out age can quickly ladle to a safe location.
To achieve protection of casting,and by installing steel weighing device,pouring more smoothly.
Small are a occupied by casting platform is conducive to pouring operation.
SMS lesson design butterfly design and pany can lift the ladle turret as a related design calculations rotary , including the drive unit power and check motor selection,reducer selection,open gear check,slewing ring selection and The calibration of anchor bolts.
Key words: Butterfly Ladle Turret;Rotary device; drives motor reducer;
