毕业设计（论文）-板坯连铸形结晶器总体设计（全套图纸）.docVIP

摘 要 连铸工艺和技术现已为全世界各国普遍采用，许多钢厂已实现全连铸。经过六十年，连铸技术和设备都有了飞速的发展，主要体现在结晶器的改进，电磁搅拌，电磁制动技术的应用，薄板坯连铸、近终形连铸、连铸自动化的实现，中间包冶金，保护渣技术等方面，采用新技术，新设备，缩短铸钢流程，提高连铸生产率，降低成本是连铸发展的趋势。 本次设计首先叙述了连铸技术的发展，阐明了课题研究的目的及其意义，再分别就国内外连铸的发展历史进行阐述，找出了我国连铸技术所存在的不足之处，比较了连铸与传统模铸的不同之处，突出连铸在钢铁冶金中的优越性。其次对弧形连铸机总体设计思想作了简单的介绍，有关弧形连铸机和弧形结晶器的相关参数的进行了比较详细的计算。最后对结晶器窄面调宽的结构和传动系统作了详细的介绍，重点是对传动系统的设计计算，包括液压缸的选型、滑动螺旋传动的设计计算，而滑动螺旋传动中对螺杆的耐磨性、螺杆强度、螺杆稳定性等进行了详细的计算。 关键词： 连铸；弧形连铸机；弧形结晶器；结晶器；窄面调宽 全套图纸加153893706 Abstract Continuous casting has been adopted all over the world，complete continuous casting has been carried into effect in many steel works．Continuous casting technologies and equipments have a rapidly progress in sixty years，for example，improving of mold，electromagnetic stirring，electromagnetic braking，thin-slab casting，near-net-shape casting，autoimmunization，punish metallurgycasting powder，etc．The trends for continuous casting are adopting new technologies and equipments，cutting casting process，increasing productivitydecreasing cost． echnology the existence of deficiencies department compare the casting and the difference between the traditional molded to highlight continuous casting in steel metallurgy in superiority. Second thoughts on the overall design of curved continuous casting machine made a brief introduction, the arc curved mold continuous casting machine and the related parameters were compared with detailed calculations. Finally, the mold narrow face width adjust the structure and transmission system are introduced in detail, focusing on the design of the transmission system, including both the selection of hydraulic cylinders, sliding screw drive design and calculation, while the sliding screw drive in the screw wear resistance, strength screw, screw stability of a detailed calculation.
