摘　　要：连接体是液压泥炮的关键零部件,工作时它正好处在高炉流铁沟正上方,距流铁沟100 mm。由于高温辐射作用时间较长,连接体内部炮泥出现偏析迅速干燥,泥质形成硬壳,导致无法堵上出铁口,迫使高炉停炉。为解决这一难题,将连接体设计成锥管结构,锥管壁为空心,空心体内部设置加强筋,隔热材料填满空心体后用盖板压紧并焊死。此设计既提高了隔热效果,又使连接体具备抗老化、耐高温等特性,使其适用于各种系列的液压泥炮,最高耐温可达1 000℃。此设计解决了液压泥炮堵铁口过程中连接体内部炮泥受热硬化、结焦、板结的难题,替代了长期以来使用外绕水管和外挂隔热板的落后方式,提高了液压泥炮稳定、安全、长期运行的可靠性。The connector is the key part of hydraulic mud gun;it works just above the iron flow ditch of the blast furnace,only 100mm away from the iron flow ditch.Due to the long time of high temperature radiation,segregation and rapid drying of the internal mud occurs,the mud hard shell is then formed,resulting in blockage of the iron outlet,and the blast furnace will be forced to stop.In order to solve this problem,the connector is designed into a conical tube structure,the conical tube wall is hollow,the hollow body is equipped with reinforcing bars,and the insulation material is filled with the hollow body,then the cover plate is pressed and welded.It not only improves the heat insulation effect,anti-aging,high temperature resistance,but also applies to various series of hydraulic mud cannon,the highest temperature resistance can reach 1 000 ℃.It solves the problems of hardening,coking and compaction of the shot mud inside the connector during the plugging process of hydraulic mud gun.Instead of the long-term use of external winding water pipe and external heat insulation plate for a long time,it improves the stability,safety and reliability of long-term operation of the hydraulic mud gun.
