Luoyang HongtengIntermediate frequency induction furnace
In lots of steel plants, the continuous billet rolling production line is the key equipment. It combines the continuous casting machine and the rolling mills to produce various types of steel products. Billet Continuous Rolling Production Line Production Process During the casting process, the casting temperature, casting speed and cooling water temperature restrict the quality of the billet. The temperature is too high or too low when the liquid steel comes out of the furnace, which is one of the reasons for the porosity and shrinkage cavity of the billet. Therefore, we should strictly control the temperature of molten steel when it comes out of the furnace. After crystallization, if the temperature of the sheared ingot drops too much, it needs to be heated with a medium frequency induction heating furnace. A temperature measuring point is set at the entrance of the induction heating furnace to monitor the temperature of the steel billet. We can adjust the cooling water temperature and water volume according to this temperature. Continuously hot-rolled steel billet have high plasticity and low deformation resistance, so larger deformation can be obtained with less energy. In rolling, the rolling temperature, the rolling speed of the continuous rolling mill,...
In the use of melting furnace, slag erosion is a common form of refractory damage. In fact, more than 59% of liner material damage is caused by slag erosion. 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 electromagnetic stirring of the metal liquid movement, the thermal stress and other effects, which will affect the service life of the melting furnace lining. Therefore, the lining material should have a certain high temperature strength, no cracking and anti-erosion under the action of a variety of forces. 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 thermal conductivity. At the same time, the lining material should have a low conductivity, can not contain magnetic induction, especially the lining knotting process is not allowed to metal or strong conductivity substances in it. When the melting furnace is working, the temperature of liquid steel can...
Induction heating is a method of transferring heat energy. The principle of induction melting is that a high voltage supply from the primary coil induces a low voltage and a high current in the metal or secondary coil. Induction furnaces are well suited for melting and alloying many metals with minimal melt loss, but do little to refine them. Induction furnaces come in two main types: coreless and channeled. Some manufacturers of all kinds of demolition waste steel, industrial waste, copper, aluminum, stainless steel, idle equipment, plant demolition, scrapped cars, etc. If these scrap metals can be reprocessed and reused through special processes, the overexploitation of the earth’s minerals can be reduced. If we can reuse scrap metal, we can consume less energy in the process and better protect the environment. This is a very important opportunity for the development of a resource-saving green economy. For example, the customer has a lot of waste cans and aluminum castings, hoping to complete the resource re-integration of waste metal and aluminum through our equipment. We can design an aluminum ingot line production program for the user. In the program, we recommend the user to use an aluminum melting furnace to solve the...
How does an intermediate frequency induction furnace convert electrical energy into heat energy to heat metal during heating? Theoretically speaking, the intermediate frequency induction furnace heating process consists of two stages. The first stage: the alternating current of the frequency conversion device of the medium frequency induction furnace generates alternating magnetic field When the alternating frequency current of the medium frequency induction furnace passes through the spiral induction coil, a magnetic field is generated in and around the space enclosed by the coil. The polarity and strength of the magnetic field vary with the frequency of the alternating current. Part of the magnetic line of force penetrates the metal charge, and part penetrates the lining material. The polarity, intensity and rate of flux change of the magnetic field, that is, the direction of the magnetic field and the number and density of magnetic field lines, are determined by the intensity of the current passing through the induction coil, the frequency, the number of turns and the geometric size of the coil. The second stage: the alternating magnetic field of the frequency conversion device of the intermediate frequency induction furnace generates induced current A part of the magnetic field line penetrates...
Metals have different melting points. For example, steel melts at 1370 ℃. Therefore, controlling the power consumed by the induction furnace will help you melt the metal at the proper melting point. This will ensure that you produce a quality product. Before buying an induction furnace for sale, make sure you are satisfied with the functionality of the induction melting furnace you choose. Before the production of the newly purchased electric furnace, we need to carry out insulation test on the induction coil to check whether the coil is normal. Before starting your electric furnace, check the furnace body, power supply, hydraulic pressure and cooling system to ensure that there is no problem with the equipment before starting the power supply. The staff in front of the furnace must wear good labor protection equipment. Before the raw materials to be melted are put into the furnace body, the intermediate frequency power of the electric furnace is reduced, and the rated power is gradually increased after the metal raw materials are put into the furnace body. During the smelting process, you must stay focused. The staff should pay attention to the changing condition of the furnace body, and deal with the...
The principle of electromagnetic induction heating is that the induced current overcomes the resistance of the conductor itself and produces Joule heat, which is used to heat the metal itself. It is heated and melted to achieve various purposes of hot processing. The induction heating system of melting furnace consists of induction coil, AC power supply and some workpieces. The advantage of electromagnetic induction heating is that the heat is generated in the workpiece itself, the heating method is fast, so the heating rate is high, the process repeatability is good, and the energy saving is relatively. Because of these advantages, medium frequency induction heating has a wide range of applications. There are the following applications: It is used for hot extrusion and hot rolling of billet before forging to complete the diathermy of billet. Used to melt metals, that is, our melting furnace, mainly smelting black, non-ferrous and rare metals; High temperature sintering tungsten, molybdenum and other refractory metals, as well as powder metallurgy. For the smelting of different metals, because of the different density of metals, the volume of the same mass of metals is different. Therefore, the size of the melting furnace body is different, and the...
