2024-05-27
Electric furnace steelmaking process and operation steps Preparation – Ensure that the melting furnace, power supply equipment, electrodes and cooling equipment are complete. – Clean the inside of the furnace and remove residues. – Prepare the charge, including scrap steel, alloys, etc. Entering the furnace and heating – Preheat the steelmaking furnace to a suitable temperature. – Gradually add the charge to the furnace and maintain good ventilation. – Use a dust collector to collect dust and reduce environmental pollution. – Turn on the power, form an arc, and use the arc to heat the charge. Charge – Add scrap steel and alloys and other smelting materials according to the requirements of the content of various elements. – Heat the charge until it is completely melted and maintain a constant temperature through the arc in the furnace. Stirring and insulation – Use a stirring device (manipulator, air gun, etc.) to stir the charge in the furnace to ensure uniform heating. – Keep insulation at the optimal temperature to increase the reaction rate of alloy and charge. Steel and slag – Add deoxidizer and alloy thinner according to the requirements of the steel grade. – Add slag according to the formula...
Scrap aluminum smelting
2024-05-21
Reclaimed aluminum smelting equipment, also called aluminum melting furnaces, includes a reflection furnace, induction furnace, resistance furnace, etc. Strictly speaking, the smelting equipment of recycled aluminum is the same as raw aluminum. However, because the shape and size of waste aluminum are different, the burning loss of the small-size material is significant, and it has not even been melted in the furnace, that is, it has been oxidized. Therefore, it is necessary to consider the oxidation burning loss and various requirements for the equipment for melting waste aluminum. Although the melting point of aluminum is relatively low (660℃), its latent heat and specific heat of melting are large, so the heat required for aluminum melting is even higher than that of copper (963℃), indicating that energy saving in aluminum smelting is very important. The aluminum melting furnace has a reflection furnace, induction furnace, resistance furnace, and so on. Reflective furnace and radial and convection-flow aluminum melting furnace. The fuel used in the reflector is natural gas, coal gas, heavy oil, and so on. According to the geometric form, there are side-loading rectangular furnaces and top-loading circular furnaces, etc. In addition to resistance furnaces, the application of reflection furnaces and induction furnaces...
Medium frequency induction furnace

There will be various problems during the use of a medium frequency induction melting furnace. Among them, electric leakage and liquid leakage are the most serious. Today, Luoyang Hongteng mainly introduces the causes and solutions of the leakage problem of the intermediate frequency induction melting furnace. Reasons for Leakage of Medium Frequency Induction Melting Furnace The leakage of medium frequency furnaces is mostly caused by insulation problems. For example, the insulation protection of intermediate frequency furnace shells, cooling systems, coils, and other structures is destroyed. Shell Insulation Peeled Off The reason for the leakage of the shell of the intermediate frequency induction melting furnace is generally that the insulation treatment of the shell is not in place. Under normal circumstances, the shell of the intermediate frequency furnace will not leak electricity. Cooling Water Hose Leaking The cooling water hose of the intermediate frequency furnace passes through the slideway in the furnace. If there is water leakage, it may directly contact the power supply in the furnace, resulting in a short circuit and grounding, resulting in electric leakage. Internal Wiring Ground If the leakage of the intermediate frequency furnace shell is only felt as a weak voltage, it may be the leakage...
Furnace maintenance
2024-05-10
It is vital to ensure that your furnace operates efficiently and safely year-round, so annual furnace maintenance is essential. Here’s what’s typically required during annual furnace maintenance: Replace the filter: Technicians will check and replace the air filter to ensure smooth airflow and improve efficiency. Inspect and clean parts: including blower motor, belts and other moving parts. Remove accumulated debris or dust to prevent malfunction. Check Thermostat Calibration: Make sure your thermostat is calibrated correctly for accurate temperature control. Check the flue and ventilation system: Technicians will check the flue or ventilation system for blockages or leaks to ensure proper airflow and safety. Check gas connections: Gas leaks can be dangerous, so technicians will check all gas connections for leaks and make any necessary repairs. Inspect electrical components: This includes checking wiring, connections, and electrical components for signs of wear or damage. Test carbon monoxide levels: Carbon monoxide leaks are a serious safety hazard, so technicians will test for leaks and make sure the furnace is properly vented. Ensure proper airflow: Technicians will check that all vents and ducts are open and unobstructed to ensure proper airflow inside the home. Regular maintenance can help extend the life of your furnace,...
Strand casting
2024-04-26
Continuous casting, or direct casting, is a continuous casting process. It has the following advantages and features: Efficient production: String casting is a continuous production process that enables uninterrupted production of metal blanks. Compared with the traditional intermittent casting process, tandem casting can significantly improve production efficiency. Excellent product quality: Due to its continuity and consistency, string casting can reduce the occurrence of defects and pores and improve product quality while ensuring product dimensional accuracy and uniformity. Save energy: Since series casting reduces the number of reheats, the series casting process generally reduces heat loss, thereby saving energy and reducing production costs. Reduce processing: Continuous casting can directly produce cast steel billets of the required final shape and size, reducing subsequent processing and saving time and costs. Wide applicability: The thread casting process is suitable for the production of various metal materials including steel, aluminum alloy, copper, etc., and has strong applicability. Environmental protection advantages: The thread casting process is more environmentally friendly and produces less waste and pollutants than traditional casting processes. Production automation: Modern string casting systems usually have an advanced degree of automation, which can realize automatic control and monitoring, reduce...
Continuous casting machines and their types
2024-04-23
Description Continuous casting machines are available in different types and specifications, and you can choose the appropriate model to produce different materials according to your needs. Continuous casting machines are used in the metallurgical industry to cast molten metal into semi-finished products continuously, rather than in discrete batches. The process offers several advantages over traditional casting methods, including increased efficiency, lower costs and better quality control. Continuous casting machine is a key equipment in the metallurgical industry. Its functions and functions mainly include: Continuous casting: Continuous casting machines are mainly used to continuously cast molten metal into semi-finished products, rather than discrete batches. This continuous casting process can greatly improve production efficiency, reduce production costs, and is beneficial to product quality control. Reduce processing procedures: Semi-finished products produced by continuous casting machines usually have high surface quality and uniform organizational structure, so they can reduce subsequent processing procedures and save time and costs. Increase output: The continuous casting machine can achieve efficient continuous production and can produce a large number of semi-finished products in a short time, thus increasing the overall output. Energy saving: Continuous casting machines are generally more energy-saving than traditional...
