Abstract
A mud gun cap is provided. The mud gun cap includes a flame resistant outer face, a ring and a mounting device wherein the mud gun cap connects to a mud gun nozzle to protect the mud gun nozzle from deterioration because of contact with molten iron and slag. The mud gun cap also prevents, or at least reduces the amount of, mud falling out of the nozzle while the mud gun nozzle is rotated into operation position. In some embodiments, the mud gun cap has a selectively movable circular barrier that at least partially prevents the mixture of mud and iron/slag in the tap hole.
Claims24
A mud gun cap comprising a breakaway flame resistant outer face on a first end of a ring, the outer face being configured to breakaway when mud is expelled under pressure through the mud gun, and a mounting device secured to the ring and extending outwardly from a second end of the ring, wherein the mounting device connects the mud gun cap to a mud gun nozzle and the mud gun cap protects the mud gun nozzle and prevents mud from falling out of the mud gun nozzle while the mud gun nozzle is rotated into operation position to plug the tap hole of a blast furnace.
A method of preventing mud from falling out of a mud gun nozzle during movement comprising:
- providing a mud gun cap having a breakaway flame resistant outer face;
- a ring;
- and a mounting device;
- installing the mud gun cap on a mud gun nozzle;
- moving the mud gun nozzle into an operating position;
- and forcing mud through the breakaway flame resistant outer face of the mud gun cap.
A mud gun cap comprising a breakaway outer face and a mounting device wherein the breakaway outer face prevents mud from falling out of a mud gun nozzle while a mud gun is rotated into position and the mounting device is configured to secure to the inside of the mud gun nozzle, and wherein the breakaway outer face is configured to break away as mud is force under pressure through the mud gun nozzle.
A mud gun cap comprising a mounting device secured to a ring;
- a circular barrier inside of the ring, the circular barrier detachably secured to, and configured to pass out of, the mud gun cap and a layer of refractory material at least partially covering the outside face of the ring.
