Kehua provides you with the safest laboratory intermediate frequency furnace
We all know that the most important thing for laboratory equipment is to ensure safety. The intermediate frequency furnace is a power supply device that changes current and is often used in various experiments. Therefore, many laboratories need intermediate frequency furnaces. So which manufacturer's experiment Is the intermediate frequency furnace for indoor use the safest and most reliable? Xiaobian thinks Kehua is a good choice! Kehua provides you with the safest intermediate frequency furnace for laboratory use. To 1000HZ) power supply device, convert the three-phase power frequency alternating current into direct current after rectification, and then convert the direct current into an adjustable intermediate frequency current, supply the intermediate frequency alternating current flowing through the capacitor and the induction coil, in the induction coil Generate high-density magnetic lines of force, and cut the metal material contained in the induction coil, generating a large eddy current in the metal material. Equipment introduction: The working frequency of the intermediate frequency induction furnace (hereinafter referred to as the intermediate frequency furnace) is between 50 and 10 Hz, and it is widely used in the smelting of non-ferrous and ferrous metals. Compared with other casting equipment, the medium frequency induction furnace has the advantages of high thermal efficiency, short smelting time, less burning loss of alloy elements, wide smelting material, less environmental pollution, and can accurately control the temperature and composition of molten metal. This eddy current also has some properties of intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. A three-phase bridge type fully-controlled rectifier circuit is used to rectify alternating current into direct current. For example, a metal cylinder is placed in an induction coil with alternating intermediate frequency current. The metal cylinder is not in direct contact with the induction coil, and the temperature of the energized coil itself is very high. Low, but the surface of the cylinder is heated to the point of redness and even melting, and the speed of this redness and melting can be achieved only 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 will be the same, and the heating and melting of the cylinder will not produce harmful gases or pollute the environment with strong light. The intermediate frequency furnace is widely used in the smelting of non-ferrous metals [mainly used in the smelting of ferrous materials such as steel, alloy steel, special steel, cast iron and non-ferrous metal materials such as stainless steel and zinc, as well as in the smelting and It can heat up, keep warm, and can run in duplex with the blast furnace. ], forging heating [used for diathermy of bar, round steel, square steel, steel plate, heat compensation, on-line heating of blue quenching and blanking, local heating, on-line forging of metal materials (such as gears, semi-shaft connecting rods, bearings, etc.) Forging), extrusion, hot rolling, heating before shearing, spray heating, hot assembly, and overall quenching, annealing, and tempering of metal materials. ] Heat treatment quenching and tempering production line [mainly for shafts (straight shafts, variable diameter shafts, camshafts, crankshafts, gear shafts, etc.); gears; sleeves, rings, discs; machine tool screws; guide rails; planes; ball joints; hardware Surface heat treatment of various machinery (automobiles, motorcycles) parts such as tools and quenching and tempering, annealing and tempering of metal materials as a whole], etc. Equipment features: 1. Saving features Fast heating speed, high production efficiency, less oxidative decarbonization, saving materials and costs, and prolonging the life of the mold. Because the principle of medium frequency induction heating is electromagnetic induction, its heat is generated in the workpiece itself, and ordinary workers use medium frequency The continuous work of the forging task can be carried out ten minutes after the electric furnace goes to work, without the need for professional furnace workers to burn and seal the furnace in advance. Due to the fast heating rate of this heating method, there is very little oxidation. The oxidation burning loss of the intermediate frequency heating forging is only 0.5%, the oxidation burning loss of the gas furnace heating is 2%, and the coal burning furnace reaches 3%. Compared with a coal-fired furnace, a ton of forgings can save at least 20-50 kilograms of steel raw materials. Its material utilization rate can reach 95%. Because this heating method heats evenly and the temperature difference between the core surface is extremely small, the life of the forging die is greatly increased in forging, and the roughness of the surface of the forging is less than 50um. Compared with gas heating, it can save energy by 5% to 40%. Good heating quality can reduce scrap rate by 1.5%, increase productivity by 10% to 30%, and prolong mold life by 10% to 15%. 2. Environmental protection features Superior working environment, improved labor environment and company image, non-polluting, low-energy induction heating furnace Compared with coal furnaces, workers will no longer be roasted and smoked by coal furnaces under the scorching sun. It can meet the requirements of various indicators of the environmental protection department, and at the same time establish the company's external image and the future development trend of the forging industry. Induction heating is the most energy-saving heating method in electric heating furnaces. The power consumption of a ton of forgings heated from room temperature to 1100 ℃ is less than 360 degrees. The heating is uniform, the temperature difference between the core surface is extremely small, and the temperature control accuracy is high. The application of temperature control system can realize precise control of temperature and improve product quality and qualification rate.
