Luoyang HongtengIntermediate frequency induction furnace
The intermediate frequency furnace is the main tool for smelting metal now. The production efficiency of the intermediate frequency furnace is inseparable from the daily maintenance. The editor of Hongteng will introduce the daily maintenance of the intermediate frequency furnace to you. 1. Furnace lining Before each start-up, observe whether there are cracks on the inner surface of the crucible. If the crack width is less than 2mm, it can continue to be used without repairing. Otherwise, it must be repaired before use. When pouring molten steel, observe whether there are cracks at the junction of the side fireplace lining and the tap hole, and whether the furnace lining at the bottom of the furnace and the slag line is partially corroded. If cracks are found, repair them in time. 2. Induction coil Appearance, check the insulation part of the coil once a month for bumps or carbonization, whether there are attachments on the surface, and whether the insulating backing plate is protruding. If any problems are found, deal with them in time. Once a week, visually check whether the coil compression spring is loose and whether the rubber tube is scratched. Check the interface daily for leaks. 3. Furnace...
The intermediate frequency electric furnace is one of the indispensable equipments in the modern foundry industry. It is efficient, fast, convenient and reliable. To ensure the efficient work of the intermediate frequency electric furnace, there is another important existence to support it, that is, the lining of the intermediate frequency electric furnace. The lining of the intermediate frequency electric furnace generally needs to choose high-quality materials with sufficient refractoriness, stable chemical properties, good thermal shock resistance, etc., and the materials that meet these requirements are often expensive. If the furnace lining is replaced early, it will cause a little economic loss, and if the furnace lining is not replaced in time, it may cause the furnace lining to be penetrated by molten iron, and even endanger the safety of equipment and operators in severe cases. It is a very important matter. Today, Xiaobian will popularize it for everyone, and judge the method of lining life of intermediate frequency electric furnace for your reference. 1. Observe the status of each instrument of the electric furnace The easiest way to judge the life of the intermediate frequency electric furnace lining is to observe the condition of each instrument when the intermediate frequency...
Friends who have been following our website for a long time know that our company mainly produces intermediate frequency melting furnaces, also known as coreless induction melting furnaces, which use the principle of electromagnetic induction to complete the heating treatment of steel, aluminum, zinc and other metals. When the furnace is working, the furnace body is in a state of high temperature. Therefore, when using our equipment, some details about safety production need to be paid special attention. Today, the editor of Hongteng will introduce some precautions for the use of melting furnaces. The first is the intermediate frequency control cabinet of the smelting furnace. Most of the electrical components in the control cabinet are exposed to the outside. High voltage and high current are passed during use, which will cause high temperature. If the staff does not pay attention to the insulation protection, it will cause electric shock on the scene and lead to the occurrence of safety accidents. When we use it, we can take the following precautions: 1. Connect the grounding wire to the furnace body, and lay insulation facilities around the operating surface of the furnace table and the control cabinet. 2. Add insulation protection to...
The 500kg induction furnace is usually a melting furnace with a furnace body capacity to melt 500kg of scrap steel. For the smelting of different metals, due to the different specific gravity of the metal, the same 500Kg metal has different volumes, so the outer dimensions of the smelting furnace body are different, and the size of the induction coil is also different. When we choose the 500kg induction furnace that suits us, we must figure out what the material of the smelting metal is, otherwise, the smelting effect will be very different, which will affect the production capacity. Today, Luoyang Hongteng editor will introduce it to you. 1. Differences in the furnace body The capacity of alloy steel, alloy aluminum and alloy copper melting furnaces are all 500Kg, and the furnace bodies are different. Taking alloy steel as the standard, the furnace body of 500Kg aluminum alloy melting furnace is equivalent to the furnace body of 1500Kg alloy steel; The 500Kg alloy copper smelting furnace body is only equivalent to the 850Kg alloy steel furnace body. 2. Difference in melting temperature The melting temperature of 500kg alloy steel melting furnace is generally 1650 degrees; the melting temperature of 500kg...
Slag sticking will occur during the use of the smelting furnace. If no solution is taken, the hot slag particles will contact the furnace wall and furnace lining, which will cause the sticky slag on the furnace wall to become thicker and thicker, and the capacity of the melting furnace will become smaller and smaller. At the same time, the smelting efficiency will also decrease, causing serious consequences. Below, the editor of Hongteng will introduce you some knowledge about sticky slag treatment in melting furnace. Reasons for the formation of sticky slag in the metal melting forge. Oxides and non-metallic impurities in the charge are insoluble in molten metal. When the induction furnace is working, the induced current will form a great stirring force on the molten metal, and the slag particles suspended in it will gradually grow up under such a strong stirring effect, and the buoyancy will also gradually increase. When the buoyancy is greater than the stirring force, the grown slag particles will float up into the melt surface. The slag particles gradually approach the furnace wall under the action of strong stirring and centrifugal force. Because the temperature of the furnace lining is relatively low, the...
For many manufacturers using induction furnaces, summer and winter are seasons that need attention. The high temperature in summer will make the smelting furnace that is already working at high temperature prone to problems, such as capacitor failure and equipment stop working, which affects normal production. Below, the editor of Hongteng will introduce to you the precautions for the safe use of melting furnaces in summer. The impact of high temperature weather on the smelting furnace 1. Induction coil, the working environment is high temperature and high heat, although it is surrounded by high temperature resistant refractory material, but for long-term use, some maintenance is required. Compared with the high temperature working environment of the intermediate frequency electric furnace, the summer weather temperature can be said to have little effect. 2. The water system is blocked, the temperature of the circulating water is too high, and the system enters the sundries, causing scaling and water blocking. There are failures of burning silicon and burning reactors, causing unnecessary losses. 3. The electricity consumption is too high. Users who use electric furnaces generally have a great demand for electricity. In summer, it is the peak period of electricity consumption. Cost saving is...
