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.
