High Melt Rate Electric Furnaces For Structural Die Casting
Rayteq's Model DC-1000 melts at 1,000 lbs/hour and can melt right next to the die casting machine to replace energy-wasting central melting.
Product Benefits
HUGE ENERGY SAVINGS
Melting at the machine replaces energy-wasting central melters, super-heating, molten metal delivery ladles, launders, and holding furnaces.
CLEAN METAL, STRONGER CASTINGS
Electrically melted metal typically yields castings with 20% better mechanical properties due to the elimination of water vapor from the gas-fired products of combustion. Water vapor contaminates aluminum by forming oxide (hard spots) and hydrogen porosity which degrade casting mechanical properties.
Model DC-1000 melts 1,000 lbs/hour and holds 4,200 lbs.
REDUCES MAGNESIUM AND STRONTIUM "FADE"
Magnesium and strontium, so critical to structural die casting properties, are less affected when electrically melted and quickly formed into castings, but can "fade" to dangerously low levels when exposed to high superheating temperatures in central melters and long time delays as the alloy slowly moves from central melter, through hot metal delivery system and holding furnaces. Like aluminum, both elements adversely react with water vapor from products of combustion in gas-fired furnaces.
INHIBITS SLUDGE FORMATION
Because sludge formation is time and temperature dependent, eliminating the superheating required by central melting and its associated hot metal delivery systems, and quickly turning freshly melted alloy into castings, sludge formation can be effectively minimized, reducing casting "hard spots" and weakened mechanical properties.
ALLOY FLEXIBILITY
Each furnace in each casting cell can melt a different alloy.
PRECISE TEMPERATURE CONTROL
Achieved with unique proportional controls, large two-ton bath, and non-contact molten metal level sensing for paced ingot addition.
SAVES FLOOR SPACE
Each furnace measures only 81" square by 49" high.
TANDEM MODEL DC-1000 FURNACES
Two furnaces with alternating automatic pouring ladles will double melting rates for heavier production.
