KGPS medium frequency power supply is a power device that converts power frequency 50HZ alternating current to intermediate frequency (300HZ to 20K HZ). It turns the three-phase power frequency alternating current into DC, then turns DC into adjustable intermediate frequency current, and supplies the intermediate frequency alternating current flowing through the capacitance and induction coil, and produces high density in the induction coil. The magnetic lines of force and the metal materials in the induction coil generate large eddy currents in metal materials.The surface of the cylinder can be heated to reddened or even melted, and the rate of redness and melting can be achieved by adjusting the frequency and the strength of the current. If the cylinder is placed in the center of the coil, the temperature around the cylinder is the same, and the heating and melting of the cylinder does not produce harmful gas and strong light pollution.KGPS medium frequency furnace is widely used for smelting nonferrous metals[mainly used in smelting steel, alloy steel, special steel, iron and other ferrous materials as well as smelting of non-ferrous metal materials such as stainless steel and zinc. It can also be used for smelting and heating of copper and aluminum and other nonferrous metals, heat preservation, and double operation with blast furnace].also can be used for forging heating, used for the heat transfer of rod, round steel, square steel, steel plate, heating, heating, local heating, on-line forging of metal materials (such as precision forging of gear, semi shaft connecting rod, bearing, etc.), extrusion, hot rolling, heating, heating, heat assembly, and heat, heat, heat, and tempering of the metal material as a whole. Heat treatment and tempering production line[main application for shaft (axis, variable axis, camshaft, crankshaft, gear shaft, etc.); gear class; sleeve, ring, disk type; machine tool screw; guide rail; plane; ball head; hardware tool and other machinery (automobile, motorcycle) parts surface heat treatment and metal material overall conditioning, annealing, tempering, etc.
Working Principle
Medium frequency power supply (KGPS-BL (parallel))
The SCR parallel inverter has a variety of circuit structures. The bridge type circuit structure is commonly used. The input end of the bridge circuit is connected with the DC power supply, the output end of the bridge circuit is connected with the load. When the diagonal arm element is triggered alternately, the bridge arm components are alternately guided and the alternating current is generated in the load circuit, thus realizing from DC to the intersection. The electric energy of the flow is transformed.
Medium frequency power supply (KGPS-BL (Series))
Under the structure condition of the series inverter circuit, when the load circuit works, it is different from the parallel inverter circuit, the connection angle of the bridge arm SCR element is less than 180 during the alternate conduction of the bridge arm element, and the reverse diode in the angle range of the SCR element is the conduction time of the reverse diode. The series inverter circuit is mostly half bridge structure. Under the same line voltage condition, the load voltage of the half bridge circuit is only half the load voltage of the full bridge structure.
