_ IF furnace supplier Daqing Daqing picture IF frequency electric furnace electric furnace is a brief introduction to 50HZ AC power frequency conversion to an intermediate frequency (300HZ to 10000HZ) of the power supply unit, which is composed of the inverter device, furnace, furnace control several part. Equipment Principle: According to the basic principle of electromagnetic induction, the three-phase alternating current frequency after rectification into direct current, DC and then becomes adjustable frequency current supplied by the capacitor and the induction coil in the flowing medium frequency alternating current induction generating circle of high-density magnetic field lines, and cutting the induction coil in the full bloom of metal material, have a huge vortex in the metallic material. Some properties of this vortex also has an intermediate frequency current, namely metal itself free electrons in the metal body has a flow resistance to produce heat. For example, put a metal cylinder on an alternating current of medium frequency induction loop, the metal cylinder is no direct contact with the induction coil, the coil itself is energized temperature is very low, but the cylinder surface is heated to redness, and even melting , and this redness and melting speed of only adjusting the frequency of the current size and strength can be achieved. If the coil is placed in the center of the cylinder, then the cylinder is the same as the surrounding temperature, heating and melting cylinder nor produce harmful gases, light pollution of the environment. Features 1. The central control circuit board design optimized by a computer, LSI optimized combination of stabilizing device performance, reliable quality, strong anti-stem sorrow. 2. The original layout is reasonable, easy maintenance. 3. On the basis of zero pressure started on the addition of automatic sweep repeat start function, voltage and current loop circuit closely tracking, smooth and stable equipment to start and stop, no current impact. The inverter start signal using a single signal sensitive trigger circuit, and further increase the startup performance of the device, so that the success rate of the equipment start to reach 100%. 5. Constant power circuit control system, with the change of the reproduction of the fast charge The voltage and current regulation on the optimum settings automatically, without manual adjustment of the inverter angle. 6. Has perfect overvoltage, overcurrent, undervoltage, water shortages, lack phase, limited pressure limiting protection system, thus ensuring the reliability and stability of the equipment work. 7. The highly integrated circuit solutions, commissioning and operation are quick, convenient and easy to learn. The company has more than in the automation of senior technical staff, with strong technical force, a strong after-sales service network and first-class service personnel. Site installation, commissioning, one year free maintenance, lifetime warranty Daqing Daqing IF furnace IF furnace supplier _ Picture
