Healdsburg, California - RAYTEQ LLC has announced that, for the first time, it will be displaying an actual Model DC-300 from its unique DT Series of high-powered electric resistance melting furnaces in Booth 1029 at CastExpo 2019 in Atlanta, GA on April 27 through April 30 th . The DT Series furnaces can be transported either by crane or forklift, and manually tilted to pour molten aluminum directly into molds, completely eliminating harmful molten metal transfers that can contaminate aluminum alloys.

DT Series tilt-pour furnaces are capable of rapid production melting because they are full-power melting furnaces, not just heated transport ladles. Each model is connected by cable to its control cabinet in the melting/holding area, and is designed for transport to degassing stations and the mold pouring area by a ceiling crane or forklift after disconnecting the quick-release cable connector. DT Series furnaces are highly insulated to minimize temperature drop after power is disconnected.

These furnaces are rugged and built for many years of tough foundry service. They feature heavy duty 3inch spherical bearings and solid steel crane lifting bails. The steel furnace shells are heavily reinforced with ship channels and belly-bands to prevent shell distortion during pouring which, together with both top and bottom internal crucible supports, virtually eliminate crucible and spout cracking during tilting. All DT Series furnaces are equipped with a robust cone-drive tilting gearbox with right-angle drive and a 30" chrome-plated hand wheel. The hand wheel is purposely forward mounted for greater operator visibility of pouring operations.

Unique features include a power shut-off at the furnace to avoid arc damage to the cable connector, and an alarm on the furnace that will sound if it is lifted without disconnecting the power cable. A second alarm at the control cabinet will sound if the furnace is not reconnected to its cable within a preset time to avoid chilling or freezing metal in the furnace.

Rayteq DT Series electric melting furnaces are currently available in two sizes: The Model DT300 holds 600 lbs. aluminum and can continuously melt 300 lbs. per hour. The Model DT-500 holds 1,500 lbs. and continuously melts 500 lbs. per hour.

The first Model DT-300 was developed as a partnering effort between Rayteq engineers and foundry managers at Edelbrock Aluminum Foundries, San Jacinto, California. Many important features of this new furnace line were a direct result of this close collaboration. The first Model DT500 was delivered to State Brass Foundry & Machine, Salt Lake City, Utah, for pouring 1,000 lb. aluminum water pump housings in a single pour.

Rayteq will also exhibit two 1,100 lb. capacity stationary electric melting furnaces at CastExpo 2019: A square Model DC-500 which can melt 500 lbs./hour and a round Model R-475 that can melt 475 lbs./hour.
