Referring to fig. 1, the present invention provides an electric furnace cooling system, which includes a control device 1, an electric furnace 2 and a cooling assembly; the cooling assembly comprises a pressure pump 3 and a liquid storage tank 4; the control device 1 is respectively electrically connected with the electric furnace 2 and the pressure pump 3; the pressure pump 3 is used for conveying the cooling liquid in the liquid storage tank 4 into the electric furnace 2 to cool an induction coil in the electric furnace 2; the pressure pump 3 is connected with the electric furnace 2 through a liquid inlet pipeline 5, a pressure sensor 6 is arranged on the liquid inlet pipeline 5, and the pressure sensor 6 is electrically connected with the control device 1; the electric furnace 2 is connected with a first liquid outlet pipeline 7, a first temperature sensor 8 is arranged on the first liquid outlet pipeline 7, and the first temperature sensor 8 is electrically connected with the control device 1. After the electric furnace 2 is electrified, alternating current passes through the induction coil to generate an alternating magnetic field, and the metal material to be heated is positioned in the induction coil of the electric furnace 2 to generate eddy current under the alternating magnetic field, so that the metal material is heated. To make metal material can heat up to the assigned temperature fast, induction coil needs to produce the alternating magnetic field of high strength, consequently, electric stove 2 needs high power operation, and induction coil also can consequently constantly produce a large amount of heats for induction coil's temperature also constantly risees, and when induction coil's temperature was close to the melting temperature of coil material, induction coil just probably appeared fusing. Therefore, the temperature of the induction coil needs to be continuously reduced by the cooling liquid. Since the induction coil generates a large amount of heat, a high-pressure coolant is supplied through the pressure pump 3 to rapidly exchange heat with the induction coil. In order to know the hydraulic pressure size in the inlet pipe way 5 accurately, in time discover to supply liquid unusual, the utility model discloses a set up pressure sensor 6 and come the real-time supervision hydraulic pressure size on inlet pipe way 5, hydraulic data can convey to controlling means 1 and show.
