摘要:加热炉的推钢机是把钢锭或钢肧推入加热炉中的设备，在出料端的加热炉上，推钢机也可以将加热好的钢锭或钢肧从加热炉的另一端推出，在钢铁产中推钢机对连续轧钢起着重要作用。

   TGJ液压型推钢机由液压油缸、液压泵站、平衡推杆及底座等组成。其主要特点是：结构简单、推力大、造价低，也可推进双排坯.本课题主要针对液压推钢机的其内容包括液压推钢机介绍、选择设计方案、液压缸计算、液压系统原理设计及液压缸的安装与维护。

关键词： 推钢机 液压系统 液压缸

Abstract:Heating furnace of steel machine is push steel ingots or steel equipment in the fetus is pushed into the furnace, heating furnace on the discharge end, pushing steel machine heating can also be a good ingot or steel fetus is launched from the other end of the heating furnace, in the steel during pushing machine of continuous rolling play an important role.

　　TGJ type hydraulic pushing machine by the hydraulic cylinder, hydraulic pump station, balance the push rod and the base, etc. Its main features are: simple structure, big thrust, low cost, also can promote the double row blank. This topic mainly aimed at the hydraulic pushing steel machine including the selection of hydraulic push steel machine is introduced, the design principle of calculation, hydraulic cylinder hydraulic system design and installation and maintenance of the hydraulic cylinder.

Key words: Push the steel mill；The hydraulic system；The hydraulic cylinder

　　目的是让我们设计与改造钢铁厂原有的液压系统,重点解决同步,主要完成液压系统的设计与计算，运动分析，集成块的设计通过该毕业设计能使学生完成专业的基本要求。学生通过工厂实践与理论学习能够完成。完成以上任务能够让我们对本专业知识进行综合运用，增强解决实际问题的能力，培养独立思考的能力，进一步提高查阅资料、计算问题、思考问题、对数据的处理、软件的使用、图纸的绘制、文字表达的能力，为以后工作打下基础。
