高炉开铁口机大臂旋转设备液压系统设计

摘 要

开铁口机是完成打开高炉铁口的关键设备，随着在现代冶炼技术的发展进步, 老式

简易开铁口机的不足逐渐暴露出来，已不能满足现代化高炉的要求，开铁口机的改制势

在必行。本课题研究的是全液压开铁口机的液压系统设计，该控制系统利用液压控制灵

活、迅速的优势，一改以往人工操纵换向为液压系统识别自动控制换向。开铁口机从回

转开始工作到工作结束回到停放位置，均采用液压全自动控制，不需人工干预，提高了

开孔能力和开孔速度，适应了现代化大型高炉的要求。该系统主要由冲击、转钎、推进

及回转四部分的液压控制系统组成，本课题主要设计了这四部分中推进与回转部分的液

压控制系统，及对这两部分液压系统的组合和系统性能验算，同时论述了各部分的计算

设计过程和必要的强度校核。

ABSTRACT

Taphole drill is a key equipment to open the taphole blast furnace, With modern smelting

technology in the development and progress, Easy open old iron deficiencies machine gradually exposed, Has been unable to satisfy the requirements of modern blast furnace, Taphole drill restructuring inevitable. This topic research is entire hydraulic pressure opens the iron gate machine hydraulic system design, The control system uses hydraulic control flexibility, rapid advantages, as soon as changed formerly the manual control commutation for the hydraulic system recognition automatic control commutation. The Taphole driller from the beginning of the end of the work to return to the work space for parking, adopted hydraulic automatic control, does not need the manual intervention, enhanced has opened the hole

ability and opens the hole speed, adapted the modernized large-scale blast furnace request.
This system mainly of the impact, the extension rock drill, advances and rotates four part of hydraulic control system composition, The design of the topics issues of this part of the four
hydraulic systems, And the total hydraulic system, the composition and properties of checking
system, It also explains the parts of the design process and calculating the necessary strength check.
