Abstract
A cooling member for positioning in the refractory wall of a cupola at a location spaced from a tap-hole has a heat-conductive member, such as a copper plate, in contact with a fluid-conducting member, such as a copper conduit. The cooling member is bent to form an L-shaped member, so that a pair of such members defines a channel at the tap-hole location. Refractory is provided on each side of the L-shaped member and forms the tap-hole on the interior within the channel thus formed. Alternative shapes for the cooling member are disclosed.
