The present invention relates to a kind of heating furnace, relate in particular to the Medium Frequency Induction Heating Furnace of the nonmetal refractory oxide of a kind of melting.This heating furnace is mainly used in the induction heating technology of oxide mixture, belongs to nonmetal heating and melting field.
Background technology
At present, in nonmetal (especially high temperature refractory oxides) melting field, there is following mode of heating: modes such as coke heating, arc heated, arc resistance heating, the heating of resistance electroslag.All there are many drawbacks in aforesaid way, though first kind of mode cost is lower, exists serious environmental to pollute.Then several kinds all need consume noble metal and graphite electrode, and device structure is complicated, and cost is high, and power is big, and efficient is low, and very high to the requirement of refractory material.
Summary of the invention
The present invention for solve existing nonmetal (especially high temperature refractory oxides) smelting apparatus in various degree exist device structure complicated; Cost is high; Power is big; Efficient is low, and to the requirement of refractory material technical problem such as very high and environmental pollution, the Medium Frequency Induction Heating Furnace of the nonmetal refractory oxide of a kind of melting is provided.Technical solution of the present invention realizes through following mode: it comprises body of heater, is provided with lower bottom base in the bottom of said body of heater, and said lower bottom base passes through the support post support fixation with the seat of honour near both sides on the body of heater; In the furnace wall of said body of heater, be provided with toroidal cavity, be the water-cooled case; Be positioned at furnace body inside wall place at said water-cooled case and be provided with inductor, said inductor and inboard wall of furnace body are close to, and round; On said body of heater lateral wall, be wound with induction coil, i.e. water-cooled cable; On said water-cooled case, be provided with cooling medium inlet and cooling medium outlet.
Characteristics of the present invention and beneficial effect: technology is simple, and is rational in infrastructure, on the basis of common Medium frequency induction equipment, improves, with low cost, improved the whole efficiency of heating furnace greatly, has no environmental pollution.Be in particular in:
Adopt the induction technology melt heating, the efficiency of heating surface is high, do not have any pollution, and equipment volume is little, is fit to large-scale production;
Inductor adopts high-melting-point, high hardness material to process, and is buried among liquid melts, and the efficiency of heating surface is high, and corrosion resistance is good;
Body of heater is that liquid cooled is surrounded, and has suitably reduced the use of exotic material, has reduced cost; Look the process route of employing, the body of heater top can be taked open, semiclosed and totally-enclosed (only staying discharging opening) mode;
Because the characteristic that electromagnetic stirring force increases with the decline of frequency adopts the suitable heating frequency, can modulate bigger electromagnetic agitation effect, makes that melt temperature and composition are more even;
Because no transmission and revolving member, the present invention is simple to operate, and good reliability can effectively be utilized the hourage of firing equipment, thereby boost productivity;
After the high-temperature fusant fusion, become the ion melt, begin conduction.Can suitably increase the efficiency of heating surface, improve temperature rise effectively.
