Dual-Transport, Lift-Pour Melting and Pouring

High-powered electric-resistance melting furnace that can be transported and tilted to pour molten aluminum

RAYTEQ LLC introduced a high-powered electric-resistance melting furnace, one that can be transported by crane or forklift and manually tilted to pour molten aluminum directly into molds. The design eliminates harmful molten metal transfers that can contaminate aluminum alloys.

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

Rayteq DT Series electric melting furnaces are available in two sizes: The Model DT-300 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 DT Series furnace, the Model DT-300, was developed by Rayteq engineers in partnership with foundry personnel at Edelbrock Aluminum Foundries, San Jacinto, CA. The first Model DT-500 was delivered to State Brass Foundry & Machine, Salt Lake City, Utah, for pouring large aluminum castings.

All DT Series furnaces are built for prolonged service in demanding operations, with heavy-duty, 3-in. spherical bearings and solid steel crane lifting bails. The shells are heavily reinforced with ship channels and belly bands that prevent shell distortion during pouring. And, together with internal crucible supports at both top and bottom, the bands offset crucible and spout cracking during tilting. All DT Series furnaces are equipped with a cone-drive tilting gearbox, with right-angle drive and a 30-in. chrome-plated hand wheel forward-mounted for greater operator visibility of pouring operations.

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