Luoyang HongtengIntermediate frequency induction furnace
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...
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,...
