This series of industrial electric furnaces is an energy-saving industrial electric furnace made of ultra lightweight refractory fibers. The industrial electric furnace is used in conjunction with a temperature control cabinet. The controller can automatically or manually control the temperature of the electric furnace, and can be equipped with a computer meter or computer control to perform multiple temperature measurements according to user requirements to ensure product quality. This series of electric furnaces is a cycle operated electric furnace. The rated temperature is 600 ℃ -1800 ℃, used for normalizing, annealing, quenching, and other heating of metal components in an oxidizing atmosphere.
Industrial electric furnace equipment is usually a complete set, including the furnace body, power equipment (furnace transformers, rectifiers, frequency converters, etc.), circuit breakers, auxiliary electrical appliances (resistors, compensation capacitors, etc.), vacuum equipment, detection and control instruments (electrical instruments, thermal instruments, etc.), automatic adjustment systems, and furnace mechanical equipment (feeding and discharging machinery, furnace body tilting devices, etc.).
The main components of an industrial electric furnace include: industrial furnace masonry, industrial furnace exhaust system, industrial furnace preheater, and industrial furnace combustion device.
Industrial electric furnace - medium frequency electric furnace
An intermediate frequency furnace is a power supply device that converts 50Hz AC power into intermediate frequency (from 300Hz to 1000Hz). It rectifies three-phase AC power into DC power, which is then converted into adjustable intermediate frequency current to supply the intermediate frequency AC current flowing through the capacitor and induction coil. It generates high-density magnetic field lines in the induction coil and cuts the metal material contained in the induction coil, generating large eddy currents in the metal material.
Due to the principle of medium frequency induction heating being electromagnetic induction, its heat is generated within the workpiece itself. Ordinary workers can continue working on forging tasks in ten minutes after using a medium frequency electric furnace, without the need for professional furnace workers to perform furnace burning and sealing work in advance. Due to the fast heating speed of this heating method, there is little oxidation. The oxidation loss of medium frequency heating forgings is only 0.5%, the oxidation loss of gas furnace heating is 2%, and that of coal-fired furnace is 3%. The medium frequency heating process saves materials, and each ton of forgings saves at least 20-50 kilograms of steel raw materials compared to coal-fired furnaces. The medium frequency furnace has fast heating speed, high production efficiency, less oxidation and decarburization, prolongs the life of the mold, superior working environment, improves the labor environment and company image of workers, low energy consumption, fast melting speed, good energy-saving effect, low burning loss, low energy consumption, self stirring function, uniform melting temperature and metal composition, good electric heating working environment, and good startup performance. It can achieve 100% startup for both empty and full furnaces.
