Description
Technical field
The utility model relates to a kind of die casting and casting industry smelting furnace, relates in particular to the molten aluminium stove of a kind of efficient energy-saving high frequency.
Background technology
Energy-saving and emission-reduction are all being advocated in countries in the world; slow down CO2 emission pollution on the environment; protection of the environment; developing green environment-friendly products, to tackle climate change, energy-saving and emission-reduction are imperative; at present; the not environmental protection of coke-fired furnace using on die casting and casting industry smelting furnace market, resistance furnace, intermediate frequency furnace high energy consumption, gas furnace investment is large.
Utility model content
Technical problem to be solved in the utility model has been to provide the molten aluminium stove of a kind of efficient energy-saving high frequency, reaches effective attenuating and pollutes, low cost, safe and reliable object.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of efficient energy-saving high frequency melts aluminium stove, is made up of body of heater and electric part; Described body of heater ecto-entad comprise successively have isolation magnetic field effect stainless steel casing, thermal insulation separation thermosphere, twine the burner hearth and the isostatic pressing formed graphite crucible that are provided with high temperature resistant low conductivity B alloy wire; Described electric part by rectifying and wave-filtering inversion main body be connected with control system, defencive function system and control system is connected, control system is connected with temperature acquisition system.
The bottom of described body of heater is provided with the leakage aluminium mouth communicating with the external world.
The thermal insulation separation thermosphere of described body of heater is made up of outer heat-preservation cotton and internal layer refractory wool plate.
The control system of described electric part is connected with LCDs.
The beneficial effects of the utility model: due to the utility model, according to the principle of electromagnetic induction heating, used the alloy coil of high temperature resistant low conductivity in isostatic pressing formed graphite crucible outside, electric part provides the high-frequency alternating current/voltage of 20KHZ for this coil, thereby on graphite crucible, form eddy current, make it rapid heating.Heat directly acts on crucible, and noenergy loss is so energy-conservation.Aluminium water and coil are isolated completely, even if crucible breaks, aluminium water can flow out from the leakage aluminium mouth of bottom, can not encounter induction alloy wire, so safety.B alloy wire long service life, electric part core parts oneself research and development, through practice in a few years, so reliable.Outer wall adopts stainless steel casing, armoured magnetic field and durable in use, and the energy adopts electrical heating, radiationless, so environmental protection.
