ã€China Aluminum Network】 Aluminum alloy is a common material in life. He is widely used and widely used in many industries. The associated aluminum melting furnace becomes an indispensable heating equipment for the above-mentioned enterprises. . Although the melting point temperature of aluminum is low, the latent heat of fusion and specific heat capacity of aluminum are large, and the energy consumption required for melting aluminum is high.
Aluminum is a chemically active metal that can chemically react with CO2, H2O, and residual O2 in the furnace gas, resulting in the loss of aluminum; and it consumes a large amount of power from bauxite, alumina, and industrial pure aluminum. When aluminum is smelted directly in a flame furnace, the metal burns approximately three times the fuel's value.
Aluminum melting furnace is a new type of high efficiency and energy saving furnace developed according to the aluminum melting process. It can well meet the requirements of the aluminum melting process: strict requirements of alloy composition, discontinuous production, large single furnace capacity, etc., and reduced consumption. , Reduce burning, improve product quality, reduce labor intensity, improve working conditions and increase production efficiency, apply to intermittent operation, with gold and melting materials and more melting.
Aluminum melting furnaces mainly include reverberatory furnaces, induction furnaces, and resistance furnaces. The fuel used in the reverberatory furnace is mainly natural gas, coal gas, and heavy oil. This article combines production reality, focuses on the factors affecting the thermal efficiency of the molten aluminum furnace that uses natural gas, and proposes the optimal design scheme and operation strategy of the aluminum melting furnace. Some of the contents are also beneficial for improving the thermal efficiency of induction furnaces and resistance furnaces.
