The invention discloses an electromagnetic induction heat preserving furnace. The electromagnetic induction heat preserving furnace comprises a shell; a mounting port is formed in the top of the shell; support legs, distributed at equal intervals, are respectively mounted on four edges of the outer wall of the bottom of the shell; insulation bricks are paved on the inner wall of the bottom of the shell; insulation cotton plates are respectively bonded on the inner walls of four sides of the shell and on the inner walls of the insulation bricks, and are mutually bonded to form an insulation cotton box; a nanometer insulation box is arranged in the insulation cotton box; shielding alloy plates are respectively arranged on the inner walls of the nanometer insulation box through screws; a cavity is formed among the shielding alloy plates; a connected casting box is mounted in the cavity; and a first cover plate and a second cover plate are respectively welded on two side outer walls of the top of the shell. The electromagnetic induction heat preserving furnace has no need to frequently remove aluminum slag, is excellent in thermal insulation effect, greatly reduces the heat dissipating rate, accelerates the heating speed, reduces the energy consumption, and can improve the economic benefits of production enterprises.
Description
Technical field [0001] The invention relates to the technical field of an aluminum liquid holding furnace, in particular to an electromagnetic induction holding furnace. Background technique [0002] The electromagnetic induction holding furnace is a heating rod immersion holding furnace that uses the induction electric heating effect of the material to heat and keep the material. The AC power supply used in the induction holding furnace has three types: power frequency (50 or 60 Hz), intermediate frequency (150 to 10000 Hz) and high frequency (above 10000 Hz). Under the action of the alternating electromagnetic field in the induction holding furnace, the eddy current is generated around the induction heating rod inside the material to achieve the effect of heating or heat preservation. Under the stirring action of this alternating magnetic field, the composition and temperature of the material in the furnace are relatively uniform, the temperature difference can be controlled a...
