Effective November 30, 2023, Joe A. Powell has sold his remaining shares in Akron Steel Treating Company, his family’s commercial heat treating business for over 80 years in Akron, Ohio, USA, to a fourth generation of new “family” ownership.

The team at AST will continue to deliver ISO and Nadcap aerospace heat treating and related metallurgical services to part making customers.

Joe A. Powell, AST’s Chairman of the Board, will remain active in the heat treating and metallurgical services community as president of Integrated Heat Treating Solutions, LLC. (IHTS). IHTS is a “heat transfer” consulting company for product development teams to enable more sustainable heat treating equipment and practices to be integrated into their new product designs. IHTS and its team of part making consultants enable their part making clients to deliver more “total added value” from heat treating and forging per BTU expended in making their products for their end users; including the design of the associated heating and quench cooling equipment for "leaner + greener, more sustainable, manufacturing" and for greater recyclability of metal alloys.

Vacu-Braze Receives New Quenching Furnace for Specialty Aerospace Materials

/ AEROSPACE HEAT TREAT, ANNEALING NEWS, FEATURED NEWS, QUENCHING NEWS, STRESS RELIEVING NEWS, TEMPERING NEWS, TITANIUM PROCESSING NEWS, VACUUM FURNACES NEWS

Vacu-Braze recently installed a new water quenching furnace in their Quakertown, PA, facility. This acquisition will allow for the expansion of capabilities to include rapid quenching of specialty aerospace materials such as steels or titanium.

The new furnace from Lucifer Furnaces, measuring 45.5”x29.5”x28,” contains argon and nitrogen atmosphere capabilities which allow for processing in a protective atmosphere even at high temperatures while maintaining AMS 2750 compliant uniformity. The pyrometry team at Vacu-Braze was able to achieve Class 2 pyrometry, opening up more available processes such as annealing, austenitizing, normalizing, stress relieving, solution treating, and tempering.

"Lucifer Furnaces was selected for the order," commented Jerry Novak, process engineer at Vacu-Braze, "[as their furnaces] are locally made and could be custom designed for the application. They are built in Eastern Pennsylvania to our desired specifications. Vacu-Braze is always happy to partner with companies that manufacture quality equipment and products in the USA."

The heat treat company also noted that this piece of equipment expands their services to existing clients while providing processes for new clients.

Manufacturer in Energy Expands with Heat Treat System

/ ATMOSPHERE AIR FURNACES NEWS, ENERGY HEAT TREAT, NITRIDING NEWS, QUENCHING NEWS

A manufacturer for the energy industry has recently announced the installment of a roller hearth furnace system. The heat treat system is comprised of two (2) box furnaces with quench tanks, a dual directional load transfer car, four (4) companion draw batch ovens, and two (2) stationary load/unload tables.

The system from Lindberg/MPH has a maximum operating temperature of 1850°F for the box furnaces, which are designed for nitrogen-based atmosphere applications. The load space dimensions of the box furnaces are 48” W x 96” D x 36” H, with larger internal chambers to provide clearance for baskets or fixtures. A snake chain pusher assembly with a dual-directional pacecar is used by each furnace to transfer the loads from the chamber to the pneumatically operating quench elevator deck.

The glycol quench tanks are designed for quick and uniform quenching, featuring an immersion oil heater and an externally mounted air-to-quench media heat exchanger. The tanks’ agitation systems include four agitators with draft tubes. The gross load capacity of the car is 10,000 lbs., and it travels linearly in front of the equipment on two embedded floor rails.

C/A Design Adds Horizontal Spray Quench Furnace

/ AEROSPACE HEAT TREAT, ALUMINUM PROCESSING NEWS, ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS, QUENCHING NEWS / Leave a Comment

A horizontal spray quench furnace has been completed for C/A Design’s heat treat facility in Exeter, NH. The system will help treat components for the aerospace and defense industry.

The furnace, from Wisconsin Oven, will be used for the solution treatment of aluminum. The system is designed to soak the product load at temperature in the furnace and then a pusher mechanism rapidly moves the load into the spray quench. The spray quench offers reduced distortion in comparison to submersion quenching.

The maximum temperature for this system is 1150°F and it has the capacity to heat a 200 pound aluminum load plus the work grid and product fixture. C/A Design’s new furnace has the capability to meet AMS 2750G, Class 2 furnace and Instrumentation Type D requirements.

47,000 Pound Gear Heat Treated and Quenched at Metlab

/ CARBURIZING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT, QUENCHING NEWS

HTD Size-PR Logo

A Pennsylvania company recently heat treated and quenched a fabricated 47,000-pound gear. In addition to this gear, about a month ago, its reverse image (with the helix in the opposite direction) was also heat treated. The halves will be matched when grinding is complete to make a complete gear to drive a rolling mill for a steel plant.

The gear, the largest Metlab has ever treated, measured 12' in diameter and has a 30” face width. Material was 18CrNiMo6-7, and case depth required was a nominal 0.275” effective case depth with a surface hardness of HRC 58 – 62. Typical taper on a gear this size is about 0.030”. Carburizing time to achieve the required case depth is about 10 days in the furnace at 17250F. After lowering the temperature of the furnace and gear to 15500F, it is quenched in oil. The transfer time from the pit furnace into the quench tank is less than a minute.

After quench, the gear will be double tempered, sandblasted and prepared for shipment to the Midwest for final grinding. Mark Podob, president at Metlab, commented, "To our knowledge, the furnace used to heat treat this series of four gears is the largest pit carburizing furnace in the United States . . . . [T]he two 47,000 pound gears are the largest that Metlab has carburized and hardened in its 25 year history."

Photographs show the gear at 1550°F being lowered into the oil tank.

Horizontal Quench System for Automotive Industry

/ AUTOMOTIVE HEAT TREAT, FEATURED NEWS, MANUFACTURING HEAT TREAT, QUENCHING NEWS

HTD Size-PR Logo

An East Troy, WI, heat treat systems manufacturer announced the shipment of an electrically heated horizontal quench system to a manufacturer of products for the automotive industry, specifically for aluminum solution treatment.

Wisconsin Oven manufactured the system with a maximum temperature of 1,200°F and interior chamber dimensions of 2' x 2' x 2'. The system has the capacity to heat 450 pounds of aluminum parts plus the steel basket within 60 minutes. Temperature uniformity of +/- 10°F at set points 850°F and 1,050°F was verified with a nine point profile test prior to shipment.

This horizontal quench system provides a 15-second quench delay from when the door begins to open until the load is fully submerged in the tank. The quench is manual, where the operator pulls the load out of the oven and onto the quench elevator using a hook. "This horizontal quench system was designed with a manual quench which is a cost-effective option and still ensures there are no improperly processed parts," commented Doug Christiansen, senior application engineer at Wisconsin Oven. "The system also features foldable unload wheel rails to save on floor space.”

Heat Treated Forging Tools Get New Quench Tank

/ FEATURED NEWS, FORGING NEWS, MANUFACTURING HEAT TREAT, QUENCHING NEWS

HTD Size-PR Logo

A forging tool manufacturer will receive an agitated heated oil quench tank to be used post-heat treatment in order to set hardness. Tools such as nippers and ladles -- critical components in the foundry and in forging equipment -- are heat treated to the required hardness and then quenched in oil to set that hardness.

The L&L Special Furnace Co. small model QTO1224 heated oil quench tank holds 65 gallons of oil and can quench parts from 50 to 75 pounds. The quench tank oil is agitated by an impeller with a ½ HP explosion-proof motor and is heated with a 4.5 kW immersion heater to maintain the oil at a slightly elevated temperature to help eliminate oil flashing and fire potential.
