Wisconsin Oven Corp., East Troy, announces the shipment of a horizontal quench system for solution heat treating of forged aluminum gun parts. Two total solution heat treating ovens were purchased along with three total aluminum aging ovens. The solution heat treat system has a maximum temperature rating of 1250°F and a work chamber of 4 x 4 x 4 feet, and is designed to heat a 1000-lb load of aluminum to 950°F.
The system is electrically heated with 144kW of heat input and zero-fired SCR power control. The recirculation system utilizes a 15,000 CFM blower with combination air flow design to maximize temperature uniformity. This horizontal quench system features guaranteed temperature uniformity (+/-10°F at 800°F and 1100° F) and meets the requirements of AMS 2750E Class 2.
The quench tank is a 12 gauge 304 stainless steel construction, 304 stainless steel removable quench tank covers (utilized to minimize heat loss), and utilizes a pneumatically actuated quench elevator with 304 stainless steel wheel rollers and lift structure. The tank has a 2,400 gallon capacity and agitation pump rated for 200 gallons per minute with galvanized steel distribution piping and horizontal style water agitation design. The tank volume is designed for a 15°F maximum water temperature rise (when load is quenched). The tank water temperature capability is rated for 140°F to 180°F normal use (with a 210°F maximum temperature capability).
The customer provides heat treating services to a large gun manufacturer. Prior to purchasing the solution heat treating system, they were outsourcing the work to a commercial heat treating company. The yearly cost savings they realized by bringing the heat treating process in house was well worth the investment in the equipment.
