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.

Abstract: The adjustable suspension system for suspending the hot top sideboard in an ingot mold comprises a bent hanger rod having one end positioned within the sideboard and adapted to be frictionally slidable along its vertical axis for vertical adjustment. The hanger is held in the desired fixed position by means associated with the sideboard which lock the hanger rod in place. The rod is normally L-shaped, but it may also be double bent. The means for locking the rod in the desired position can be strips such as metal strapping ridgily fixed in the hot top board and extending outwardly therefrom to lock the hanger rod in the desired position by wrapping the strips about the rod, extending the rod through the strips in appropriately positioned holes, hooking the rod to the strips by S-shaped hooks, or the like.
