Description
Technical field
The utility model belongs to metallurgical technology field, relates generally to a kind of aluminium melting furnace, is specifically to be related to a kind of electromagnetism
Sense aluminium melting furnace.
Background technology
In recent years, in face of increasingly serious environmental problem and energy crisis, energy-saving and emission-reduction are all being advocated in the whole world energetically, especially
It is for consuming energy and polluting all more serious metallurgical technology industry, how to carry out energy-saving and emission-reduction transformation, have become this area
Technical staff has to the factor considered when designing the kind equipment.
Wherein, in metal metallurgy smelting industry, traditional smelting furnace is main to carry out heating melting with coal, oil, coke etc. for fuel,
It has the disadvantage：1st, energy consumption is big, and coal equal energy source will produce heat by burning, and part coal is not sufficiently combusted just into clinker；2nd, imitate
Rate is low, and the fuel such as coal has substantial amounts of heat energy to be lost to high-temperature flue gas in air in burning, what high-temperature flue gas was taken away
Heat accounts for more than the 40% of calory burning；3rd, maximum discharge, high pollution, the raw material such as coal can discharge substantial amounts of nitrogen oxidation in burning
The pernicious gases such as thing, carbon dioxide, sulfur dioxide, pollution air and surrounding enviroment；4th, product quality is low, and production cost is high, coal
The Combustion System of the raw materials such as charcoal is more difficult, and crucible temperature is uncontrollable, causes aluminium coolant-temperature gage too high or too low, not only influence production
Product qualification rate, while cast-iron pot accelerated ageing, overtemperature also easily occur the defect such as burns out, causes production cost to increase.At present,
For the discharge of pernicious gas in reduction fusion process, there is part aluminium processing enterprise to employ and heated with resistance wire or Elema
Electric heated aluminum melter, this electric heated aluminum melter transferring heat in crucible from the bottom to top by heat exchange pattern, heat without
Method makes full use of, and thermal losses is higher, and smelting efficiency is relatively low, it is impossible to meet production needs；And the use of resistance wire or Elema
Restricted lifetime, the phenomenon such as often occurs aging, blows, need to often change, and influences the production efficiency of aluminium melting furnace, and increase aluminum melting
The maintenance cost of stove.
Chinese utility model patent open file CN204478811U discloses a kind of electromagnetic induction smelting furnace, the electromagnetic induction
Smelting furnace is that the cannulated sleeve that alumina silicate fibre is made is arranged outside crucible, sets what nanomicroporous material was made in cannulated sleeve periphery
Electromagnetic induction coil is installed outside heat insulation layer, heat insulation layer.The electromagnetic induction smelting furnace solves crucible internal high temperature pair during aluminum melting
The influence of electromagnetic induction coil operating temperature, makes the operating temperature of electromagnetic induction coil may remain in less than 150 DEG C.But row
The insulating properties for electromagnetic induction coil do not obtain enough attention in the industry, and most enterprises are only to be made in coil
After the completion of the conventional insulated paint of last layer is sprayed on surface again as insulating meanses, such insulated paint is organic substance mostly, normal
Temperature is lower to have good insulating capacity, but with the rise of temperature, the performance of this kind of insulated paint deteriorates rapidly, itself also by
Gradually it is carbonized, after temperature is more than 100 DEG C, insulated paint can be thoroughly carbonized nigrescence, and insulating capacity is lost completely, causes coil in electricity
Interlayer short circuit dischange is formed in the presence of pressure, the operational efficiency of equipment is reduced, lasting electric arc can be produced when serious, not only easily
Electric controling element is damaged, great potential safety hazard can be also brought to operator.
