Description of Requirement FY20 Contract: Arc Melting Furnace ABJ-900
BACKGROUND:
The U.S. Army Engineer Research and Development Center (ERDC), Geotechnical and Structures Laboratory (GSL), Concrete and Materials Branch (CMB) requires an Arc Melting Furnace ABJ-900 for the synthesis of advanced metal alloys. The ABJ-900 features a vacuum suction mold that allows materials to be cast with higher geometric tolerances. The development of these high-performance materials with high geometrical tolerance are required for the mission of CMB.
SPECIFICATIONS:
The CMB requires a new Arc Melting Furnace ABJ-900. Specifications for the equipment are:
• Large Bell Jar hinged loading configuration, 10.00" (255 mm) Diameter X 11.50" (292 mm) High
• 100% 304L grade stainless steel vacuum chamber construction
• A single copper stinger rod with Thoriated Tungsten Electrode. Six spare Thoriated Tungsten Electrodes provided with furnace system
• Custom Copper 228mm diameter X 12.7mm deep hearth plate arrangement. Note that this hearth can be provided with one large cavity or several small cavities machined to customer specification (free of charge when specified a time of order)
• Operating temperature over 3500 °C (6332 °F)
• Inert Gas Backfill System with relief valve and flow meter
• Sight Window, nominal 4.0 inch (102 mm) diameter, view port and one (1) illumination port with halogen lamp
• Mechanical evacuation system for 10-3 Torr (mbar) range vacuum provided standard.
See also optional diffusion and turbo pump high vacuum options. Vacuum read out included.
• Safety "Pressure Compensated” Bellows for the stinger rod.
• Water cooling manifold with water flow safety interlock
• Control Console with 6061-T651 anodized aluminum cabinet top.
• Power Supply: 450 Amp @ 100% Duty Cycle, 600 Amp @ 56% Duty Cycle. Rated 22 kVA. Supplied with foot control. (Customer to specify line voltage at time of order).
• Additional material load lock
• Vacuum/suction casting mold
• Button flipper for melt manipulation
• Modified frame with lockable casters
PROVISIONAL ITEMS:
• NA
DELIVERY:
The Arc Melting Furnace ABJ-900 system should be provided to the ERDC on or before September 30, 2020.
