The polygonal electromagnetic plasma melting reactor is characterized in that: the reaction chamber is provided with a rod-shaped auxiliary electrode which is arranged in the center of the reaction chamber along the longitudinal axis and can move up and down, so that the auxiliary electrode can be lifted up or down, and when the auxiliary electrode is lowered down, the hollow space on the device for leading out the molten liquid is closed, and the molten liquid is heated additionally.

Therefore, the stable fluidity of the melt flow from the diversion port can be adjusted by the aid of an additional direct-current power supply.
The polygonal electromagnetic plasma melting reactor is characterized in that: the seat frame is made of electrode graphite, and the flow guide port is made of siliconized compact graphite. In addition, the seat frame and the diversion opening are coated with a layer of zirconium dioxide containing wear-resistant and fire-resistant components.
The polygonal electromagnetic plasma melting reactor is characterized in that: the bottom of the reaction chamber is provided with a lining built by chrome-magnesium refractory bricks, and the lining inclines from the inner wall of the reactor to the center of the bottom.
The polygonal electromagnetic plasma melting reactor is characterized in that: the side wall of the reaction chamber is made of a non-magnetic material stainless steel plate, and the outer wall of the reaction chamber is provided with an insulated water cooling shell; regulating and controlling a valve on the main water collecting tank, and respectively injecting cooling water from the lower part by a hose; the bottom and the cover of the reaction chamber are respectively provided with two water inlet pipes and a water outlet pipe.
The work of the invention is carried out according to the following steps:
the reaction chamber is fed with crushed material, namely the grinding material with the particle size of 5-8 mm, through a pipeline of a feeding port. First a planar layer of small particles of a conductive material in the form of a dispersion is created between the surface layers of abrasive particles in the central part of the reaction chamber. For example, graphite powder is used which can be used to connect 3 or 6 rod-shaped electrodes. Then three controllable silicon power supplies which can be regulated are switched on, and then current is conducted to penetrate through the graphite layer to heat the graphite layer. And transferring the heat generated by the current to the abrasive body connected to the graphite layer, and finally forming a working molten pool in the reaction chamber.
In order to remove the melt from the reaction chamber, the additional fixed rod-shaped electrode is lifted, the hole on the flow guide opening is opened, and when the fluidity of the solution is enough to ensure that the solution flowing out of the flow guide opening can flow freely, the auxiliary electrode is stopped at a slightly lifted position in the solution in the reaction chamber. If the melt flow can not freely flow out of the flow guide opening, the additional fixed rod-shaped electrode is put down to seal the central hole of the flow guide opening. The molten pool is continuously heated by the main power supply.
If the molten liquid flow from the diversion opening changes diameter or is in an intermittent state in the process of pouring the solution from the reaction chamber, an additional fixed power supply is started, and current passes through a circuit formed by the additional fixed electrode, the solution and the diversion opening to supplement and heat the solution and the diversion opening. Therefore, the temperature, fluidity and viscosity of the melt flow flowing out of the guide holes installed in the apparatus for pouring out the solution in the reaction chamber are increased.
