Luoyang HongtengIntermediate frequency induction furnace
When the induction furnace is working, it is easy to cause accidents such as splashing due to the presence of moisture on the crucible wall, burying hidden dangers for the personal safety of operators. How to avoid similar dangers from happening? A very common practice is to preheat, and today we will give you a brief introduction. The first is the preheating process. 1. When using an induction furnace, preheat the crucible to about 200°C for 30 minutes without adding material, and dry it for 60 minutes. This is to allow the surface moisture of the crucible to volatilize and prevent bursting in the initial stage of use. 2. After preheating, the crucible should be heated to 900℃-1000℃ (about 2 hours) as soon as possible, keep the temperature for 20-30 minutes, and then return to the temperature when the metal needs to be smelted. This is done so that the crucible can quickly pass through temperature areas prone to oxidation. 3. After each preheating, it is only necessary to keep the electric furnace running. Unless the furnace is stopped or the crucible is damped again, there is no need to preheat again. There are also some inspection notes. 1. Carefully...
Any country will use a large amount of metal materials such as steel when carrying out industrial production and infrastructure construction. Over time, these metal materials experience various wear and tear, such as rusting and scratching. At this time, these metal materials need to be replaced. In fact, we can recycle and reuse the scrap metal that has been replaced. The smelting furnace can help us heat the scraps of scrap steel, melt them into molten steel, and cast them. Turn scrap steel into new castings, rolls or ingots and other workpieces, so as to achieve the purpose of recycling scrap steel. So, what are the specific structure, function and characteristics of the melting furnace? Luoyang Hongteng Xiaobian is here to talk about the melting furnace. The melting furnace is composed of thyristor intermediate frequency power supply, furnace body, heating induction coil, furnace lining material to protect heating coil, cooling circulation device, tilting furnace system, leakage furnace protection system, etc. The melting furnace uses the principle of electromagnetic induction to heat the metal, so that the heat is generated inside the metal itself, which can speed up the melting speed of the metal. And it is very simple to use....
Induction furnace charging is the basis for ensuring the smooth progress of the metal smelting process. If the feeding is unreasonable, it will increase the burning consumption of the metal, which will eventually lead to excessive power consumption and increase the input cost. Therefore, it is very important to know some knowledge about the feeding of induction furnace. The editor of Hongteng will share with you some precautions about feeding. 1.Different metal materials have different performance characteristics. For the charge with low density and low melting point, larger blocks, such as aluminum, can be used. Charges with high density and high melting point, such as ferro-tungsten, ferro-molybdenum, micro-carbon ferro-chromium, etc., must be broken into smaller pieces. 2.The size and frequency of the furnace body determine the size of the smelting material. Low-frequency, large-capacity furnaces can use large pieces of charge. Higher frequency, smaller capacity furnaces require the use of smaller chunks. 3.When feeding, try to ensure that the upper part is loose and the lower part is compact. When the upper metal bulk density is small, it is helpful for the downward smelting material, which can speed up the smelting speed of the metal and ensure stable heating efficiency. 4.When...
As a good equipment for melting metal in the foundry industry, induction furnaces have solved many problems for many users. However, few users know that the temperature and humidity of the surrounding environment also affect the induction furnace in the process of using it. If the environment exceeds the standard, it will affect the working efficiency of the intermediate frequency furnace in light, and cause some failure problems in the electric furnace in serious cases. Today, the editor of Hongteng will introduce to you, those working environments suitable for induction furnaces. 1. The altitude environment where the equipment works should not be too high, preferably below 1000 meters above sea level. 2. The best working environment temperature of the equipment should be in the range of +5℃~40℃. 3. Under the standard of 25℃, the relative humidity of the surrounding environment shall not exceed 90%. 4. There should be no conductive dust, explosive gas and corrosive gas that can seriously damage metal and insulation around the furnace body, so as to avoid equipment damage or personal injury. 5. The fluctuation of the three-phase power supply is not more than ±5%. If the fluctuation is large, it will easily lead to the...
Induction furnaces are mainly used to smelt metals, and in the process of use, the consumption of electricity is very large. Therefore, for many users, how to reduce the power consumption of induction furnaces is a very important thing to solve. Today we will introduce some methods to you. 1. On the premise of ensuring the normal operation of workers, the production site should try to maintain a smaller space layout, which can shorten the connection lines of the production line, reduce the loss caused by current transmission, and save electricity. 2. When designing the furnace body, it is necessary to select the appropriate furnace body size and induction coil to ensure the smooth flow of current and improve the heating efficiency of the induction coil. 3. Control the temperature of molten steel. This requires the operators of the production line to pay attention to the working conditions of the induction furnace at any time, identify the timing of feeding, to assist in stirring the steel, and improve the melting speed of the metal. Doing this can reduce power consumption very well. 4. Each manufacturer has its own production process and equipment materials. If some manufacturers use inferior and thinner...
Heating metals is the easiest way to change their shape. After heating, metals can be processed into various shapes and functional products, and then applied to our lives. The first heating method is to create a high temperature environment by burning fossil fuels, and then heat the metal in this environment. In this way, it takes a long time to complete the heat treatment of the metal. In the 1920s, Faraday discovered the principle of electromagnetic induction, which was then used by humans to heat metals. The alternating current is transmitted to the induction coil, and the magnetic field is generated in the coil. The magnetic field directly penetrates the metal in the coil, making the electrons inside the metal active, thereby achieving the effect of rapidly heating the metal itself. Using this principle, people have invented a new equipment that can smelt metal more quickly, which is an induction furnace. When the induction furnace heats metal, it does not need to burn traditional fossil fuels and does not emit any toxic substances. The whole working process is clean and pollution-free, which is very helpful to protect the environment. More importantly, when the induction furnace is working, there is no...
