Abstract

An impact pad for receiving a stream of liquid metal having a bottom wall with an upper surface against which said liquid metal is intended to impact, a side wall extending in an upward direction along the periphery of the bottom wall, and an annular wall extending inwardly from the side wall. The annular wall, together with the bottom wall and side wall define a metal receiving chamber having an opening through the annular wall. An upward extending collar wall extends along the periphery of the impact pad above the throat opening. The collar wall has a contoured inner surface merging with an upper surface on the annular wall.
