Aluminum Melting Furnace.Schaefer Furnaces, Inc., released its Dual Energy Aluminum Melting Furnace, which can run on natural gas or electricity. The furnace is designed with burners in the roof for either gas or propane propane, CH3CH2CH3, colorless, gaseous alkane. It is readily liquefied by compression and cooling. It melts at −189.9°C; and boils at −42.2°C;. and features electric heating Electric heating Methods of converting electric energy to heat energy by resisting the free flow of electric current. Electric heating has several advantages: it can be precisely controlled to allow a uniformity of temperature within very narrow limits; it is element mounting holes that can be temporarily plugged when fossil fuels are used. To use electric energy in the furnace, the nozzles from the burners are easily removed and replaced by insulating plugs. The electric heating element mounting holes are unplugged and silicon carbide silicon carbide, chemical compound, SiC, that forms extremely hard, dark, iridescent crystals that are insoluble in water and other common solvents. Widely used as an abrasive, it is marketed under such familiar trade names as Carborundum and Crystolon. resistance elements are inserted and connected. The changeover (programming) changeover - The time when a new system has been tested successfully and replaces the old system. can be implemented in less than 2 hr, even on a hot furnace. The control panel is set up for either gas or electric use. The furnace requires less than 1500 BTU/lb of metal melted in gas configuration and 0.23 kW/lb of metal melted with electricity. Available sizes range from 400-3000 lb/hr.- |
