Industrial Ovens to United Tool & Die Company For Heat Treating Aluminum
Wisconsin Oven Corporation announced the shipment of two industrial ovens to United Tool & Die Company in West Hartford, CT. An electrically heated draw batch oven (SDB oven) with a pitted manual quench tank will be used for aluminum solution heat treatment of parts. An electrically heated enhanced duty walk-in batch oven (EWN oven) will be used for aluminum aging and annealing of parts. The new equipment is replacing antiquated furnaces at the customer’s facility that were difficult to keep certified and consumed a lot of power to heat. Due to space constraints and a very low ceiling, Wisconsin Oven designed both ovens with rear mounted heater houses and recirculation fans.
Bob Roberts and Rich Paquette of United Tool & Die Company were very instrumental in laying out the equipment with the goal of making it as easy as possible for the operators to use. They modified the quench tank by adding rails and a rolling load cart to create an efficient loading process for the operators. When the quenching process is complete there is an overhead hoist that is used to lift the product back onto the rolling load cart.
The standard draw batch oven has a maximum temperature rating of 1,250°F and a work chamber of 3’W x 3’H x 7’L. A guaranteed temperature uniformity of +/-10° F at 500°F, 750°F, 900°F, and 1,000°F per AMS 2750E Class 2/Instrumentation Type C was verified through a nine (9) point profile test conducted in an empty oven chamber under static operating conditions.
The enhanced duty walk-in bath oven has a maximum temperature rating of 800°F and work chamber dimensions of 6’W x 8’D x 5’H. A guaranteed temperature uniformity of +/-10° F at 300°F, 550°F, and 800°F per AMS 2750E Class 2/Instrumentation Type C was verified through a fifteen (15) point profile test conducted in an empty oven chamber under static operating conditions.
“The new Wisconsin Oven equipment provided an efficient solution for our customer not only in energy costs but also operator use. Bob Roberts and Rich Paquette were very focused on making sure that the equipment was laid out in a way that maximized their production rate.” – David Burke, Sales Representative, Wisconsin Oven Corporation
