RH真空处理顶枪升降及旋转机构设计 摘要 RH真空处理是提高钢水质量的方法之一，它是由德国鲁尔钢公司与真空泵厂家赫拉乌斯公司共同设计的。顶枪机构是其中非常重要的一部分。通过顶枪除碳、除磷、脱氧、脱硫、去除夹杂物。可使钢水质量得到有效的提高。顶枪在工作中需要完成升降和旋转两个动作，升降运动的目的是使插入钢水中的枪体离开真空室,而旋转运动的目的是使枪体离开工作位，以便维修、检查炼钢设备。在本次设计中顶枪升降动作是通过齿轮蜗杆减速器减速加链传动机构实现的,旋转动作通过液压传动来实现。 通过对该升降及旋转机构的设计，加深对炼钢设备的进一步了解与认识，同时熟练掌握运用齿轮传动、蜗杆传动、链传动等机构的设计方法，树立起严谨的设计理念，从而达到综合训练的目的，为将来走向工作岗位打下坚实的基础。 关键词：RH真空氧枪； 升降机构； 旋转机构 RH vacuum Top Gun movements and institutions designed rotary Abstract RH vacuum processing is to improve the quality of molten steel one of the ways, it is from Germanys Ruhr steel company and the vacuum pump manufacturers Helawusi jointly designed. Top Gun institutions is one very important part. In addition to the gun through the roof of carbon, phosphorus, deoxy, desulfurization, the removal of inclusion. The quality of molten steel can be effectively improved. Top guns in their work to be done movements and rotating the two movements, movements of the movement to make molten steel inserted in the left chamber of the gun, and rotating the purpose is to leave the guns of work stations, for maintenance, inspection steel-making equipment . In the design of top-gun action movements through the worm gear reducer slowdown and chain drive mechanism to achieve, through hydraulic rotary action to achieve. Rotating through the movements and the design, deepen their understanding of the steel-making equipment to further understanding and awareness, and mastering the use gear transmission, the worm transmission, such as the chain drive design and establish strict design concept to achieve comprehensive training The purpose, to work for the future and lay a solid foundation.
