Artificial gem(ZrO2) made through cold crucible method,sapphire smelting(AI203) made through cold crucible method;MgO smelting:Smelting and purification of metallic oxide and metal alloy.
Equipment is adopts AC-DC-AC variable frequency power supply structure,using IGBT component and PWM chopping voltage adjustment mode,the inverter adopts high power MOSFET forming the whole bridge resonant inverter,this can guaranteethe constant power output in the process of smelting and pulling.High quality Gem,stable process,high efficiency and energy saving,it is the ideal choice to replace the traditional vacuum tube.
