Luoyang HongtengIntermediate frequency induction furnace
Steel is a valuable and useful resource in the manufacture of cars, planes and trains. We really can’t get around without it. However, the tools we use to melt and shape this metal are just as important. Without an induction furnace, the process of melting metal would be difficult. When we use steel, induction heating is an ideal heating method, can be controlled by heating depth and heating time, to meet the surface quenching requirements of the workpiece. Induction heating can be used in the following scenarios: Diathermy: During the heating process, the internal and surface temperatures of the whole workpiece are roughly equal, which is called diathermy. Induction heating for dithermic heating has the advantages of high heating efficiency, fast speed, reduce metal burning loss, easy to control the temperature, to ensure the quality of heating, so it has been more and more widely used. Smelting: When induction furnace is used for smelting, it has these advantages, can provide workers with a better working environment, high heating efficiency, less burning loss of alloying elements in the solution, easy control of the composition, high quality products, especially suitable for melting various high-grade alloy steel. Sintering: Sintering is used in powder...
Medium frequency induction melting furnaces use electromagnetic heating for smelting, which is more efficient. Unlike conventional melting systems, which take a long time to melt the metal, induction furnaces quickly heat up to high temperatures. Induction heating systems can do in a few hours what would normally take days because of their high heating efficiency. The induction system is energy efficient. Induction heating system is not only very efficient in heating, but also very energy saving. Induction furnaces consume less energy than oil furnaces, while maintaining high temperatures. This makes production more cost-effective and the metal produced can be sold at a lower price. Heating capacity produces better results. The heating capacity of induction melting furnaces is considered superior to that of other types of furnaces. Induction heating stoves can heat up to extremely high temperatures, while more traditional stoves struggle to reach those numbers. These high temperatures are what makes induction melting furnaces ideal for melting any type of precious metal. What’s more, the intense heat generated by the induction furnace can be easily controlled by the professional who operates it. Traditional heating furnaces such as oil stoves usually require a lot of effort and sweat to control the...
If the medium frequency induction furnace is melting metal, if it is melting steel, the temperature of liquid steel in the furnace can reach 1700℃ or above, and the temperature of liquid iron can reach 1500℃ or above. In the melting furnace, the temperature difference between the inside and outside of the furnace wall is very large, about 10% ~ 15% of the heat is lost through the furnace wall. In order to reduce the heat loss and improve the thermal efficiency, the lining material should have low heat conductivity. Therefore, the furnace lining material should have good refractibility, and the furnace lining material should be selected to meet the melting temperature or withstand partial and frequent high temperature according to the melting material. At the same time, the lining material should have a low conductivity, can not contain magnetic induction, especially in the knotting process of the lining is not allowed to metal or strong conductivity substances included in it. In the process of melting, the furnace wall should be subjected to the impact force of the metal charge, the static pressure of the metal liquid, the force of electromagnetic stirring the metal liquid movement, the thermal stress and...
Medium frequency induction automatic heating furnace is a non – standard heating equipment which uses medium frequency induction heating to heat metal workpiece. Equipped with automatic feeding system, plc control system and infrared temperature measurement system and other equipment, so that IF induction heating into automatic heating mode. Here, Luoyang Hongteng editor to introduce this intermediate frequency induction automatic heating furnace. Production process of intermediate frequency induction automatic heating furnace: Sorting of workpiece storage platform → automatic feeding machine → roller transport → rhythm adjustment → cylinder pushing → inductor heating → infrared temperature measurement → large screen display → fast feeding machine → temperature sorting → forging hammer or press. Medium frequency induction automatic heating furnace composition: Medium frequency induction heating power supply, by rectifier and inverter thyristor, reactor, the main control line Furnace body frame, mainly designed for inductor heating coil bracket, used to support inductor furnace head, including capacitor bank, waterway, circuit, gas path. The induction heating system is composed of spiral induction coil, furnace lining material, furnace mouth plate, coil bottom support, cooling water way, etc. Fast discharge device, short material generally adopts fast forward material, long material generally adopts clamp roller discharge. Infrared temperature measuring...
Today we are going to talk about the use of intermediate frequency furnace. Before opening the medium frequency electric furnace, it is necessary to check the electrical equipment, water cooling system, inductor copper pipe, etc., only in the condition of these several equipment intact can the furnace be opened, to ensure the safety of heat treatment, otherwise it is forbidden to open the furnace. Some customers call to consult that their home IF the furnace start more difficult, to see what is the cause of this, now has affected the production, about this fault, today red Teng old engineer to summarize for you to solve the problem of IF furnace start. The difficulty in starting the intermediate frequency furnace is mainly caused by the following 4 aspects, which can be checked by themselves and repaired for solution. There may be damage or breakdown of the components of the bridge arm on the inverter side. We can use a multimeter to focus on checking the thyristor resistance value; Check the resistance and capacitance absorption, whether the circuit capacitor breakdown; Check whether the external circuit is short. It is possible that the thyristor with bridge arm on the inverter side is not...
What we recommend to you is the medium frequency induction furnace. Medium frequency induction furnace is widely used in the smelting of non-ferrous metals and ferrous metals. Its power supply is a power supply device that converts 50HZ alternating current to medium frequency (300HZ to 1000HZ). The medium frequency furnace has fast melting speed and uniform heating temperature, which is very popular among users. About the use of intermediate frequency furnace, we should pay attention to its working environment. Work at an altitude of less than 1000 meters above sea level. The best working environment temperature can be in the range of -10℃~40℃. We need to pay attention to the presence of conductive dust, explosive gas and corrosive gas can seriously damage metal and insulation around the furnace body. These can damage the furnace body or injure personnel. On the cooling of furnace and electric cabinet, we should pay attention to the temperature of cooling water between ±5℃~30℃, the hardness of water is not more than 8, the turbidity is not more than 5, the pH is between 6.5 and 8.5. When the electric furnace is in use, we should pay attention to its power. These affect the rate of...
