Introduction to the characteristics and principle of Guangzhou intermediate frequency forging furnace
The intermediate frequency forging furnace is a new type of power supply device. Now this kind of equipment is used in many industries, because the safety performance of the intermediate frequency forging furnace is very stable, and Kehua understands the characteristics and principles of the intermediate frequency forging furnace in Guangzhou. Guangzhou intermediate frequency forging furnace 1. Intermediate frequency forging furnace Intermediate frequency forging furnace is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (above 300HZ to 10KHZ). Second, the principle of the intermediate frequency forging furnace converts the three-phase power frequency alternating current into direct current after rectification, and then converts the direct current into an adjustable intermediate frequency current, which supplies the intermediate frequency alternating current flowing through the capacitor and the induction coil, which is generated in the induction coil. High-density magnetic lines of force, and cutting the metal material contained in the induction coil, generate a large eddy current in the metal material. 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. For example, if 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 low, but the surface of the cylinder is heated to the point of redness or 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. Third, the characteristics of the intermediate frequency forging furnace Technical characteristics The main features are: the use of IGBT devices, the use of high-efficiency combined resonance technology. Adopt low-inductance circuit arrangement, adopt large-scale digital circuit. The heating speed is fast, the production efficiency is high, the oxidation decarbonization is less, and the cost of materials and forging die is saved continuously working. There is no need to worry about the waste of heated blanks due to power outages or equipment failures. Due to the fast heating rate of this heating method, there is very little oxidation. Compared with the KGPS thyristor intermediate frequency furnace, each ton of forgings saves at least 20-50 kg of steel raw materials, and greatly saves electricity. Each ton of steel is heated, and the power consumption is 310 degrees. Compared with KGPS thyristor intermediate frequency, it can save 20%-30% power. Because this heating method heats evenly, the temperature difference between the core and the surface is extremely small, it will not cause grid-side pollution, the power supply transformer will not heat up, the substation compensation capacitor will not heat up, and it will not interfere with the work of other equipment. Reduce the power supply transformer capacity. Excellent working environment, no pollution, low energy consumption Uniform heating, extremely small temperature difference between the core surface and high temperature control accuracy Induction heating generates heat in the workpiece itself, so the heating is uniform, and the temperature difference between the core surface is extremely small. The application of temperature control system can realize precise control of temperature and improve product quality and qualification rate. Guangzhou intermediate frequency forging furnace Guangzhou intermediate frequency forging furnace features and principle introduction and Kehua understand, this intermediate frequency forging furnace has many advantages, the most important of which is high production efficiency, energy saving and environmental protection.
