Luoyang HongtengIntermediate frequency induction furnace
The principle of induction heating equipment is similar to the working principle of intermediate frequency induction furnace, both belong to the principle of electromagnetic induction. Therefore, the heating effect produced by induction heating equipment with different frequencies is also different, which determines the level of heating quality. The power of the intermediate frequency furnace determines the heating speed and efficiency. The following will introduce the power and frequency selection method of the induction heating equipment to you. Frequency selection method of induction heating equipment According to different output frequencies, induction heating equipment can be roughly divided into: ultra-high frequency, high frequency, super audio frequency, intermediate frequency and so on. Different heating processes require different frequencies. If the wrong frequency selection cannot meet the heating requirements, such as slow heating time, low work efficiency, uneven heating, and the temperature does not meet the requirements, it is easy to cause damage to the workpiece. If you want to choose the frequency correctly, first of all, you must understand the heating process requirements of the product. Generally speaking, there are the following situations: Workpiece diathermy For example: fasteners, standard parts, auto parts, hardware tools, rigging, hot upsetting and hot rolling of twist drills,...

The happy 11th holiday is over, and the articles on our website will be updated normally from today. As a professional manufacturer of industrial furnaces, Hongteng’s technology has always been very mature. Today, I will introduce some basic configurations of the intermediate frequency furnace to you. These are also mentioned in our previous articles. Any set of modern equipment needs some supporting equipment to play the biggest role. As the mainstay of many equipment in the foundry industry, the intermediate frequency furnace is not only composed of a furnace body. In addition to the furnace body of the intermediate frequency furnace, the power supply and electrical control part, the transmission device, and the water cooling system. They are all indispensable equipment for the composition of the intermediate frequency furnace. What role do the supporting devices of these intermediate frequency furnaces play in the working process of the intermediate frequency furnace? Furnace body part This is the most important part. The lower part of the furnace body in the composition of the intermediate frequency furnace is equivalent to the human body. Usually medium and small intermediate frequency furnaces are equipped with two furnace bodies, one is used for normal production use,...
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...
When users buy an intermediate frequency furnace, they need to know some methods about power supply debugging. Today we will summarize them for you. Overvoltage debugging methods and steps Turn on the power supply, slowly increase the power potentiometer to make the intermediate frequency voltage reach 750v, adjust the overvoltage protection potentiometer clockwise, and the overvoltage indicator light is on. The power potentiometer returns to zero, and the quenching equipment automatically resets the protection system. Turn the overvoltage potentiometer two to three turns counterclockwise, and release the voltage limiting potentiometer. Restart the power supply to make the voltage of the intermediate frequency furnace rise to 800v ~ 820v, and slowly adjust the overvoltage potentiometer clockwise to make the intermediate frequency power supply overvoltage protection action, and the overvoltage indicator light is on. Start again to verify that the overvoltage protection value is accurate. Restore the voltage-limiting setting value, and adjust the potentiometer of the inverter angle ceramic disc to make the ratio of the intermediate frequency voltage and the DC voltage about 1.4. Note: The debugging of overvoltage and voltage limit should be carried out under no-load condition. These two debuggings are strictly prohibited under overload conditions! Otherwise the consequences...
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...
