Smelting Process and Apparatus
First Claim
1. A smelting vessel for producing molten metal including a refractory lined hearth that in use is in contact with molten slag or molten metal in the vessel, with the hearth including an upper part that in use is in contact with molten slag in a slag zone in the vessel and a lower part that in use is in contact with molten metal in a metal zone in the vessel, with the hearth including a plurality of heat pipes positioned in a refractory lining of the upper part of the hearth for cooling the refractory lining, and with the heat pipes being positioned in a plurality of radially spaced-apart rings completely around the hearth.
