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.
