The working principle of the intermediate frequency electric furnace heating equipment How to use the intermediate frequency electric furnace heating equipment-Kehua

In the smelting industry, the most indispensable thing is heating equipment. Because no matter what metal is smelted, it needs to be heated and melted first. Now many companies are using intermediate frequency electric furnace heating equipment. Kehua will take you to understand the working principle of intermediate frequency electric furnace heating equipment. How to use intermediate frequency electric furnace heating equipment? Intermediate frequency electric furnace heating equipment Working principle of intermediate frequency electric furnace heating equipment Intermediate frequency electric furnace heating The working principle of the equipment is to put a metal cylinder in the induction coil with alternating intermediate frequency current. The metal cylinder is not in direct contact with the induction coil. The temperature of the energized coil itself is very 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 as long as the frequency and the strength of the current are adjusted. The equipment adopts series resonance or parallel resonance, so the power factor is higher. Compared with traditional heating methods, it has the advantages of high efficiency and low pollution. The equipment has a wide range of applications in forging and metal heat treatment industries. Intermediate frequency electric furnace heating equipment How to operate intermediate frequency electric furnace heating equipment 1. Intermediate frequency induction heating frequency conversion equipment, there are two types of generator type and thyristor type. The maximum voltage of the intermediate frequency current can reach about 750V, and the safe electricity rules must be observed when using it (the power of the inverter is generally greater than 100kW). The IF computer room should be well ventilated and kept clean, tidy and dry. IF equipment must have more than two people to start the operation, and designate the person in charge of the operation. 2. Operators should be familiar with and abide by the operating procedures of intermediate frequency equipment, and wear the prescribed protective equipment. The workpiece should be removed from burrs, iron filings and grease, otherwise it is easy to cause arcing. During operation, it is necessary to prevent the workpiece from contacting the sensor to cause arcing. Kehua reminded everyone to pay attention to the safe operation rules of electrical, mechanical and hydraulic transmission. The equipment needs to be repaired by a special person. Before repairing, discharge the capacitors with a discharge rod. It is strictly forbidden to carry out emergency repairs with electricity. 3. In order to prevent the large workpiece from bursting and hurting people during power frequency induction heating, the operation rules of power frequency heat treatment and the corresponding heat treatment process rules for large workpieces must be strictly followed. Large workpieces should be ultrasonically inspected one by one. For workpieces with defects such as white spots, serious segregation and looseness, it is forbidden to use power frequency equipment to heat them. The workpiece should be free of burrs, iron filings and oil to prevent arcing. In the production operation, the person in charge must be designated, and the operator must be familiar with and abide by the operating procedures of the power frequency equipment. Intermediate frequency electric furnace heating equipment is the most commonly used equipment in smelting enterprises. When using intermediate frequency electric furnace heating equipment, you must operate in accordance with the above procedures, otherwise it is easy to cause safety accidents.
