VESSEL FOR MOLTEN SLAG, AND METHOD AND DEVICE FOR MAKING HARD AGGREGATE FROM WASTE USING SAID VESSEL.

摘要

The discharge opening (13) of the melting furnace (11) for melting wastes is inserted into the heat insulating room (10), a plurality of vessels (24) for molten slag are movably arranged in the room (10) by the use of a truck (25) or the like, and said vessels are successively transferred to a position below said discharge opening (13). Each vessel (24) for molten slag is provided with an inner mold (32) made of metal higher in corrosion resistance to molten slag than a heat insulating material (30) and spread over the inner surface of said heat insulating material (30) which is configured like the vessel.
