Abstract

A catchment pit for molten metal and cooling water. has a floor formed with a recess and upwardly open chambers in the pit for receiving the molten metal and supported on the floor. Portions of the side walls of the chambers adjacent respective floors of the chambers and these floors are made of refractory and water-permeable material. A drainage module extends in the pit down into the recess and has a refractory water-permeable side wall so that water in the chambers can pass down into the recess. Granular bulk material fills the pit around and under the chambers and drainage module. A drainage conduit extending down in the drainage module to an intake end in the recess below the chambers. A pump connected to the drainage conduit can thus evacuate water from the recess.
