Wherein, described spiral agitator is connected with bell, and bell is disposed over high-speed electric expreess locomotive, and motor is placed in furnace shell top and is tightly connected with furnace shell, it is connected with fixing porous stator structure with helical-blade rotor below motor, one-piece auger stirring structure structure liftable;
Wherein, described upper charging mechanism is screw feeding device, is tightly connected with bell, and top charge door is that Seal Design can keep body of heater vacuum to seal;
Wherein, described bell automatic mobile device is connected with above-mentioned agitating device, charging mechanism;
Wherein, described vacuum system is connected with described bell by pipeline and isolating valve;
Wherein, described oil sump filter is arranged on the pipeline between described smelting furnace and described vacuum system.
Wherein, described equipment includes water-cooled and hydraulic system;
Wherein, described smelting furnace body of heater is provided with turndown device;
Wherein, the vacuum equipment of described vacuum system is multi-stage mechanical vacuum pump.
Have employed the smelting technology application apparatus of above-mentioned a kind of metal bath, owing to applying the technology of said spiral agitating device, both possessed the feature of vacuum outgas, a grinding system can be constituted with fixing porous stator structure again by helical-blade rotor, particle cluster in melt is circulated grinding, is allowed to dispersed;And its melting and degassing, add powder and can separately carry out, effectively improve production efficiency;Vacuum outgas and particulate abrasive function effectively reduce the air content of melt, and in actual test, the gas content that can reduce melt or metal-base composites stirs the 50% of air content to traditional mechanical, thus increases the consistency of material.Additionally, homodisperse particle mean size can be reduced to about 10 μm, can effectively improve the performance of metal-base composites.
It addition, compare existing stirring degassing or air blowing degassing method, and traditional granule paddling process, the degassing of the present invention and granule dispersal device improve degassing and granule dispersion efficiency, and invest little, take up an area few, flexible operation and the advantage increasing production capacity.
