2 Horizontal Quench Systems Expand Semiconductor Operations

/ ALLOY FABRICATIONS NEWS, ANNEALING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT

Two electrically heated horizontal quench systems have been shipped to a supplier for the semiconductor industry. The systems will be used for the annealing and rapid cooling of various high purity alloy parts.

The operating procedure for each horizontal quench system from Wisconsin Oven includes loading the product on a work grid located on the loading platform. Once the load is lifted into place, a pusher/extractor mechanism located at the front of the quench tank moves the load onto the quench lift platform, then the furnace pusher/extractor mechanism pulls the load into the furnace for annealing.

After completing the heating cycle, the vertical lift door opens, the furnace pusher/extractor transfers the load onto the quench lift platform, and the load is lowered into the water quench tank. After the load has sufficiently cooled, the quench lift is raised, and the front mounted pusher/extractor mechanism pulls the load back onto the scissor lift. While the load is pulled onto the scissor lift, a blow off system removes the majority of the water from the load.

Exothermic Atmosphere Generator Supplied to Skana Aluminum

/ ALUMINUM PROCESSING NEWS, ANNEALING NEWS, ATMOSPHERE GENERATORS NEWS, BRAZING NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT, TEMPERING NEWS

Skana Aluminum Company in Manitowoc, Wisconsin, has recently been supplied with an Exogas™ exothermic atmosphere generator.

The atmosphere generator from SECO/WARWICK USA, an American SECO/WARWICK Group subsidiary, provides an indirect-chilled exothermic atmosphere for annealing, brazing, normalizing, drawing, and tempering.

Says Marcus Lord, managing director of SECO/WARWICK USA, “At 30,000 CFH, it is one of the largest atmosphere generator units we’ve made to date. It should be plenty large enough to meet the exothermic atmosphere needs of the multiple processes within the Skana plant.”

Skana has also placed an order with the furnace supplier for a smaller atmospheric gas drier for use elsewhere in the plant.

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.

3 Heat Treat Rod Overbend Furnaces Shipped

/ AEROSPACE HEAT TREAT, ANNEALING NEWS, ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS, HARDENING NEWS / Leave a Comment

Three electrically heated RO pit furnaces with air-cooled fans have been shipped from Riverside, MI. The furnaces will be used for heat treating various steel components.

“These pit furnaces are designed for a nitrogen atmosphere,” commented Kelley Shreve, general manager at Lindberg/MPH. “They have been designed to utilize three independent heating zones for optimal temperature uniformity and meet AMS 2750G Class 3.”

These heat treating pit furnaces from  have a maximum temperature rating of 2,000°F and are designed to handle a wide range of part sizes. Two of the units have work chamber dimensions of 28″ x 36” and a maximum gross workload of 2,000 lbs. each. The third furnace has work chamber dimensions of 60” x 109” and a maximum gross workload of 20,000 lbs.

All of the pit furnaces have pneumatically operated lids with three-way hand control valves and limit switches that disconnect power to the heating elements when the covers are open. The pit furnaces are electrically heated with heavy duty rod overbend heating elements.

NC Forgings Producer Secures Heat Treat Line

/ ANNEALING NEWS, ATMOSPHERE AIR FURNACES NEWS, AUTOMOTIVE HEAT TREAT, FEATURED NEWS / Leave a Comment

A roller hearth iso-thermal annealing line for steel automotive impression forgings is to be installed for a major American producer located in North Carolina.

The system comes from CAN-ENG Furnaces International Limited. It will be capable of both iso-thermal annealing and normalizing with a high temperature furnace operating under exothermic atmosphere. The line includes a separate low temperature roller hearth furnace, automatic bin dump and loading system, integrated tray/basket return system, and level II automation technology. The time frame for the heat treat line installation is in Q2, 2024.

Prior to the sale of this heat treat furnace, the furnace supplier had provided a mesh belt normalizing furnace, cast link belt normalizing furnace, and a roller hearth iso-thermal annealing furnace to the forgings producer.

A gas generator was recently installed for Jomarca, one of the biggest manufacturers of fasteners, bolts, nuts, and fixing elements in Brazil. The generator will supply exothermic gas to a continuous wire annealing furnace, which is part of the manufacturer’s efforts to meet market demand efficiently and sustainably for baling wire in the construction industry.

Using exothermic gas instead of nitrogen, the company expects to reduce operating costs, increase production efficiency, and improve the wear properties and finish of its wire products.

“By providing them with our latest generator technology," commented Marcio Boragini, sales director for Brazil at UPC-Marathon, "we have helped Jomarca improve process efficiency, achieve sustainability, and exceed their customers’ expectations for high-quality wire products.”

Jomarca already owns two endothermic gas generators from UPC-Marathon, a Nitrex company with headquarters in North America. In March of this year, the company upgraded its wire operations with a 150 m3/h capacity ExoFlex generator to ensure consistent gas composition and prevent scale formation on the wire surface.
