Abstract
All of a cast-iron or cast-copper stave cooler's weight is supported inside a furnace containment shell by a single gas-tight steel collar on its backside face. All the coolant piping in each cooler has every external fluid connection collected and routed together through the one steel collar. A wear protection barrier is disposed on the hot face. At least one of horizontal rows of ribs and channels retain metal inserts or refractory bricks, or pockets that assist in the retention of castable cement and/or accretions frozen in place from a melt, or an application of an area of hardfacing that is welded on in bead, crosshatch, or weave pattern.
