Luoyang HongtengIntermediate frequency induction furnace
When using an industrial metal melting furnace, we need to know the information about the furnace body heating charge, and I will share it with you today. We need to master the chemical composition of the various charge materials used, carry out careful and reasonable batching calculation, and use the reasonable combination of various charge materials to ensure that the main chemical components in the molten steel meet the requirements. The content of harmful impurity elements should be as little as possible and not exceed the standard, so as to avoid delaying the smelting time due to the adjustment of the composition, and the molten steel will be scrapped due to the unqualified composition, which will increase the material consumption and power consumption. Charges must be properly classified according to chemical composition, impurity content and lump size. The size of the charge block should be adapted to the frequency of the power supply, and the frequency of the power supply used by the induction furnace decreases with the increase of the furnace capacity. Therefore, large-capacity intermediate frequency furnaces can use large pieces of charge, and small-capacity induction furnaces can use small pieces of charge. The distribution of the induced current...
Today we will introduce to you the common measuring equipment in induction heating. The induction furnace uses an infrared thermometer to measure the temperature of the blank coming out of the discharge port of the inductor of the intermediate frequency furnace. This temperature signal is fed back to the intermediate frequency furnace control system and the PLC control system through the temperature control system. Using these parameters, we can adjust the heating temperature and control the temperature classification cylinder to achieve a qualified process. When the blank temperature reaches the requirement, it can pass. If the blank temperature is lower than the process requirement, then heat the blank temperature. The temperature of the blank is higher than the process requirements, and the heating temperature of the blank enters the low-temperature material frame and the high-temperature material frame respectively to realize three-sorting for the induction furnace. The automatic sorting mechanism of induction furnace three-sorting consists of photoelectric switch, infrared temperature detector, regulator and PLC. After the photoelectric switch detects the discharge, it sends this signal to the PLC. After the PLC detects the discharge signal, it sends out an instruction to detect whether there is an upper and lower limit alarm...
Industrial furnaces are used to smelt metals, and there are many types on the market. The intermediate frequency furnace that we Hongteng uses the most, adopts the principle of induction heating. The metal heating of induction heating equipment is also called intermediate frequency induction forging furnace, intermediate frequency induction diathermy furnace, intermediate frequency induction pre-forging heating furnace, intermediate frequency induction heating furnace, and intermediate frequency induction furnace. Today we will introduce to you about induction heating equipment. The first is the application of the device. It involves the heating, heat treatment and melting of metals. The heating application range is in the process of forging, extrusion, hot rolling and shearing of metal materials. Heating and heat treatment such as quenching and tempering, annealing, and tempering of the whole metal material. The composition and configuration of induction heating equipment is generally composed of intermediate frequency power supply, electric heating capacitor, induction furnace body, feeding and discharging transmission device and temperature measurement equipment. When using induction heating, pay attention to the cooling method of the induction coil of the equipment. Common cooling methods are: Closed circulating cold zone tower system, pool + circulating pump cooling system; Pool + plate heat exchanger cooling...
We, Hongteng, are a company that produces industrial furnaces. Today, I will share with you some knowledge about industrial metal furnaces. When the industrial furnace is working, the power is a problem that everyone is concerned about, so how to improve the power of the intermediate frequency induction furnace? The coil is the key to converting electrical energy into heat, so the design of the coil is very important. The advanced coil design should be based on the actual use of the induction furnace, according to the principle of electromagnetic field, through the optimization calculation of the computer industry software to determine a good plan, using the new coil anti-parallel winding technology, better gather the magnetic field, improve the magnetic field stirring force, The error between the design power of the induction coil and the actual operating power is not more than 5%. We can increase the wall thickness of the induction coil. Thick-walled induction coils will provide more smelting energy, and thick-walled induction coils have larger current-carrying cross-sections than induction coils with other cross-sections, so the coil resistance is low and more energy can be used for smelting. And because the thickness of the surrounding pipe wall is uniform,...
When using the intermediate frequency furnace, in order to ensure the safety of use and the work rate, we must pay attention to the safety operation of the intermediate frequency furnace. Do you know the safety operation of the intermediate frequency furnace? Today, the editor of Hongteng will let you know about it. boot operation Close the low-voltage switch frame switch of the incoming line, observe whether the three-phase incoming line voltage and ammeter indication are normal, and adjust the power adjustment potentiometer to a small value. Press the control power on button, after 2 to 3 seconds, press the “main circuit on button”, and then press the “inverter start button”, the intermediate frequency power supply starts to work, at this time DC voltmeter, ammeter, intermediate frequency frequency meter, power meter There are instructions. After the startup is successful, slowly adjust the power knob to the required power position, and input the power; if the intermediate frequency is not established (that is, the startup fails), press the “inverter stop” button to reset it, and then press “inverter start” again. shutdown operation When shutting down, first turn the power adjustment knob to the smaller position, and then press the “inverter stop”...
As a manufacturer of industrial furnaces, we produce many medium frequency induction furnaces. Medium frequency induction heating has the characteristics of fast heating, uniform heating, non-contact heating, no pollution, small operation area and high productivity, so it is used in many fields such as surface quenching of industrial metal parts, metal melting, bar heat penetration, etc. It is becoming more and more widespread, so do you know what the principle of medium frequency induction heating is? The principle of intermediate frequency induction heating is to use the method of electromagnetic induction. When the magnetic flux surrounded by the conductor loop changes, an induced potential will be generated in the loop. The conductor in the alternating magnetic field also generates an induced potential under the action of electromagnetic induction, and an induced current is formed in the conductor. The induced current overcomes the resistance of the conductor itself to generate Joule heat, and this heat is used to heat the conductor itself, causing it to heat up and melt. To achieve a variety of thermal processing purposes. The basic components of an induction heating system include an induction coil, an AC power source and a workpiece. Depending on the heating object,...
