Drop Bottom Quenching/Water Tank Movable Furnace by elman
Drop bottom quenching is a Worldwide the largest aircraft and transportation alloy components are heat treated by elman Drop Bottom quenching with water tank movable Solutionizing furnaces.
Drop bottom furnaces are typically used when very fast water quench times are required. The furnaces are designed to meet all requirements of Aerospace Material Specifications (AMS) AMS 2750E and AMS 2770N, NADCAP, RPS-953 and Boeing Aircraft (BAC) specifications. These furnaces are also used for solutionizing, ageing of structural parts, and in forging industries of aluminium alloys.
Elman has manufactured and installed drop bottom furnaces since 2006, with smallest load dimension of 3 ft up to the largest exceeding 65 ft. Our drop bottom with water tank movable furnaces are used for components as small as aircraft fasteners, all the way up to 65 ft wing extrusions. We have built drop bottoms for up to 20 ft diameter forged rings for rockets, large turbine inlet cones, and 30,000 pound loads for aircraft forgings.
For rapid and uniform convective heating our fan and duct air champer configurations is guarantee close temperature uniformity throughout the load chamber and parts. Computational Fluid Dynamic modeling predicts reliable machinery performance and allows elman and our customers to optimize part density and load rack configuration to increase machinery through-put.
Part marking and data acquisition can allow PLC/SCADA interface with your ERP software to assure bottom line predictability and part tracking documentation.The quenching trolly movement is faster than other furnace.
