The economic benefit of electromagnetic pump application - Aluminum waste preheating, dry and melting fire will be directly under the burning of violent, metal burning less 2%-15%; - The waste of aluminum powder recovery goals up to 97% -98%; - By original aluminum smelting of batch operations for the continuous operation and improve labor productivity 30%-35%; - In the whole smelting process, melt through the aluminum electromagnetic pump water cycle, and melt temperature and chemical components uniform; - As a result of the shaft furnace charging, with the ordinary open the door of the feeding of furnace type lost little compared temperature, gas leak less, energy saving effect; - Can without open the door in the case through the vertical shaft furnace to join metal magnesium, silicon metal, manganese metal alloy ingredients to allocate the alloy component; - Due to the aluminum waste is in a closed system to join, no smoke overflowing in workshop, the working environment is very good; - Improve productivity, reduce labor intensity; - Shortening the cycle time fuses 10%, reduce energy consumption.
