Luoyang HongtengIntermediate frequency induction furnace
As an equipment for casting and hot processing of metals, the melting furnace consists of several parts, such as frequency conversion device, furnace body and furnace control. Its working principle is to convert the three-phase power frequency alternating current into direct current, and then convert the output of the inverter circuit into a single-phase intermediate frequency alternating current, and realize the heat treatment of the metal according to the principle of electromagnetic induction. In order to ensure that the smelting furnace can work efficiently and safely, it is necessary to carry out standardized operation. Today, Hongteng editor will introduce three details about the standardized operation of the smelting furnace. 1. Precautions before opening the furnace The smelting furnace must be inspected for electrical equipment, water cooling system, inductor copper pipes, etc. before the furnace is opened. The furnace can only be opened when these equipments are in good condition to ensure the safety of heat treatment. Determine the person responsible for sending electricity and opening the furnace, and the person in charge shall not leave the post without authorization. During the work, the external conditions of the inductor and the crucible must be supervised to prevent someone from touching the...
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...
Recently, an Australian customer purchased an intermediate frequency aluminum shell furnace from our company, which is mainly used for melting steel, iron, metal, etc. The supporting equipment includes transformers, closed cooling towers, etc. Customer requirements: raw materials are scrap metal, scrap iron and other scrap metal raw materials. The required output is 150KG per hour. The final customer purchases a set of 150KG medium frequency melting furnace and N10T closed cooling tower Features 1. The melting furnace capacity is 0.1T-20T, and the melting speed is fast, 40-60 minutes per furnace; 2. The equipment has a self-test function, which can detect the fault information of water temperature, water pressure, overcurrent, overvoltage, and lack of phase in real time; 3. The waterway adopts carbon-free hose, and all the water dividers and clips are made of 304 stainless steel; 4. It can work continuously for 24 hours, save energy and environmental protection, and reduce costs and labor costs. After reading our case, if you are interested, you can estimate the metal bar you need to process and the demand for production capacity, and then communicate with us. We will design a reasonable solution for you and configure a suitable production line according to...
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...
