1、第44页高炉无料钟炉顶上密封阀和上截料阀的设计摘要高炉是钢铁冶炼的重要设备，高炉炼铁是获得大量生铁的主要手段。高炉冶炼的原理是把氧化铁还原成含有碳硅锰硫磷等杂质的生铁。高炉的炉顶装料设是用来装料入炉并使炉料在炉内合理分布，同时还要起到炉顶密封作用的设备。近代工业的迅速发展，带动钢铁冶金技术的发展，传统的高炉炉顶设备存在着设备复杂、密封性能差等缺点。本文设计的无料钟炉顶装料装置具有设备结构简单、传动效率高、设备重量轻、布料灵活、密封性能好等优点，能够满足现代高炉大型化和超高压操作的要求。而本文主要设计串罐式无料钟炉顶的上密封阀、上截料阀等机构，主要包括主传动方案的设
2、计，基本参数的选择计算，重要零件的设计和强度校核，以及一些标准件的选择和校核，如轴承、键、液压缸等。无料钟炉顶简化了炉顶的设备的结构，满足现代化大生产的要求，对于今后高炉炉顶的发展和研究提供了新方向。全套图纸，加关键词：高炉无料钟、炉顶设备、高炉冶炼、高压操作、密封阀、截料阀第44页Designforflow-controlvalveandconsealvalveofBeel-lessBlastFurnaceTopAbstractTheblastfurnaceisanimportantironandsteelsmeltingequipment,theblastfu
