Resistance loss, the induction coil in cold conditions are located at outside heat-insulation layer, and total losses are not optimal.
The content of the invention
The utility model is led to solve present in prior art contradiction to be present disclosed in sensing heating reduction magnesium apparatus
A kind of the problem of cause can not be realized, there is provided copper coil magnesium reduction jar electromagnetic induction heater of high temperature.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of copper coil magnesium reduction jar electromagnetic induction heater of high temperature, including reductive jar, the first heat-insulation layer, the line of induction
Circle and the second heat-insulation layer, described reduce are laid with the first heat-insulation layer on tank wall；The induction coil is positioned over the first heat-insulation layer
Outside；The second heat-insulation layer is laid with outside the induction coil；The induction coil uses copper cash, and operating temperature is 900~1000 DEG C；
The electromagnetic induction heater is placed in vacuum environment or filled with the protective gas environment for mitigating copper induction coil oxidation
In.Fig. 2 gives magnesium smelting reducing system total losses (perunit value) under different heat conduction losses with temperature residing for induction coil
Variation relation, in the case where ensureing that transimission power, copper cash quality are certain, it is seen that under different insulation layer thicknesses, i.e., any
Under heat conduction losses, with the reduction of induction coil diameter, it is raised in temperature residing for heat-insulation layer, and total losses are smaller.Sensing
When coil is in heat-insulation layer outermost, i.e. cold conditions, total losses reach maximum, and energy utilization efficiency is minimum.Copper cash fusing point is 1083
DEG C, when the maximum temperature for allowing induction coil to work reaches 1000 DEG C, Fig. 3 gives change of the total losses with heat conduction losses
Relation.It can be seen that in 1000 DEG C of high temperature, total losses minimum value be present so that energy transmission efficiency reaches maximum.
First heat-insulation layer and the second heat-insulation layer are by the relatively low ceramic alumina fiber of thermal conductivity factor and hard carbon felt structure
Into, according to Temperature Distribution to the first heat-insulation layer and second insulation layer material be arranged, temperature be not higher than 500 DEG C when, using oxygen
Change aluminium ceramic fibre as insulation layer material, during higher than 500 DEG C, using hard carbon felt as insulation layer material.
The utility model uses above technical scheme, compared with prior art, the utility model advantage specific as follows：
1st, induction coil is positioned in heat-insulation layer, and operating temperature reaches 900~1000 DEG C, rather than cold conditions, so can be with
Reduce the total losses of reduction process, improve energy transfer efficiency；
2nd, the protective gas for mitigating copper induction coil oxidation is vacuumized or filled outside reductive jar, can effectively prevent from sensing
Coil copper cash high-temperature oxydation.In the case of being vacuumized outside tank, tank body pressure-bearing greatly reduces, and material calorific intensity demand reduces, because
This, reductive jar need to only use common heat-resisting steel making；
When the 3rd, working, the high-frequency alternating current being applied to by supply unit on induction coil produces the magnetic of alternation in reductive jar
.Thus induced-current is produced in reductive jar.Heat is by conducting and radiating two caused by the electric current inducted in reductive jar
Kind mode heats to furnace charge.By this electromagnetic induction process, electric energy contactlessly passes to reductive jar and carrys out heating response
Furnace charge；
4th, the utility model is designed reasonably, the total losses of reduction process can be reduced, improve energy transfer efficiency；Mainly
Produced for the high-vapor-pressure metal such as magnesium, lithium, strontium, calcium thermal reduction.
