Abstract

The invention discloses a melting furnace. By means of the melting furnace, heat of gas in a combustion chamber is kept at the temperature of a molten metal crucible holding chamber, resources are utilized more effectively, and meanwhile, an energy saving effect is achieved. Fire grates are arranged in melting chambers correspondingly, traditional reflection-type heat transfer is changed, fuel gaspenetrates through holes of the fire grates and melts metal, and the heat efficiency is improved; draft guide tubes are connected between preheating chambers, gas is exhausted through exhaust outletsafter circulating to and fro in sequence between the preheating chambers through the draft guide tubes, the temperatures of tail gas of the melting chambers can be greatly decreased, and the heat efficiency is improved; and part of the tail gas exhausted out of the preheating chambers flows back to the combustion chamber, the other part of the tail gas is exhausted out through a counterflow heatexchanger, meanwhile, fresh air enters a combustion engine through the counterflow heat exchanger, and accordingly, the air can be preheated in the counterflow heat exchanger. According to the novel energy-saving melting furnace with the low burn out rate, the heat efficiency is increased to 85% or above, the aluminum oxidation rate is dropped to 0.3% or below, and the melting furnace has the advantages of energy saving and lowering of production cost and is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of melting furnaces, in particular to a novel energy-saving melting furnace with low burning loss. Background technique [0002] In the field of metallurgy, melting metal is a very common and important process. The molten metal can be used to cast metal parts of various shapes. The melting furnace is a new type of high-efficiency and energy-saving aluminum melting furnace developed according to the aluminum smelting process. It is mainly used for melting and heat preservation of aluminum ingots, and it can well meet the aluminum smelting process. The furnace is composed of melting furnace, crucible, heating element, furnace cover lifting mechanism, electrical automatic temperature control system and so on. The furnace shell is welded into a cylindrical shape by section steel and steel plate. There is a hole at the lower part of the front end of the furnace body, for the crucible to leak out due to corrosion and oxi...
