Title:
METAL SMELTING FURNACE
Document Type and Number:
WIPO Patent Application WO/2017/157278
Kind Code:
A1
Abstract:
A metal smelting furnace includes a furnace bottom (10), a furnace wall (7), a furnace top wall (2), a furnace door (1) and a furnace hearth; wherein the upper half portion of the furnace hearth is a hot smoke gas chamber (4), and the lower half portion of the furnace hearth is used to dispose metals to be heated; a reinforcing heat transfer layer (8) for improving heat absorption rate of the metal is provided between the upper half portion and the lower half portion of the furnace hearth. The metal smelting furnace improves heat transfer intensity of heat of the hot smoke gas in the upper half portion of the furnace hearth transferred to the metal to be heated in the lower half portion of the hearth to more than twice to tens of times, which directly results in a reduced temperature of exhaust smoke and a reduced heat loss, meanwhile increasing the temperature rise rate of the metal and shortening the fuel burning time.
