A manufacturer is expanding their heat treat capacities with a new box furnace, designed for air atmosphere applications, from a North American furnace provider.

Lindberg/MPH's heat treat furnace has a maximum temperature rating of 1,250°F and a load capacity of 6,000 lbs and is designed to accept fixtures that are 48" wide by 84" deep by 48" high. A full-width roller hearth is located across the furnace chamber floor for manual loading and load support. Temperature is controlled by a Honeywell DC2500 Series controller with an adjustable alarm set-point and latching output relay; the controller disconnects the power to the heating elements and sounds an audible alarm in an event that temperature exceeds desired set-point.

“The high velocity forced heating system circulates heat evenly within the furnace chamber," commented Bill St. Thomas, business development manager at Lindberg/MPH. "[This] assures rapid and uniform heat transfer throughout the workload.”

Ceramic matrix parts materialize when nanofibers of silicon carbide or other ceramic nano threads are wound together, forming various sheets and 3D-printed shapes. The nano threads in the process are coated with proprietary resins that must be completely removed from the substructure using heat. The resulting finished product is lighter and stronger than titanium.

L&L Special Furnace Company, Inc.'s Model XLC3672 has a work zone of 32” wide by 32” high by 66” deep. It has a single zone of control with a temperature gradient of ±20°F at 1,100°F using four zones of temperature control with biasing to balance any temperature gradients. The Model XLC3672 is controlled by a Eurotherm Nanodac Mini 8 program mechanism with overtemperature protection.

RIDGID® TOOLS received twin furnace systems from a North American supplier. These systems will heat parts from ambient to 975°F, soak for two hours, cool to 120°F, soak two hours, and then repeat. This will increase the production capacity of the company's current operations. 

The furnaces, from DELTA H®, feature a stainless steel interior with low mass ceramic fiber insulation for minimal heat retention, are designed to receive baskets with parts from an Ipsen Titan vacuum furnace, and include a floor guide system to enable precise load placement.

"We had a challenge with utilization of our [current] vacuum furnace where a secondary heat treatment might be better accomplished with a convection furnace," explained Nicolas (Nic) Willis, metallurgist/heat treat manager at Emerson Professional Tools, provider of RIDGID® TOOLS. "This would dramatically increase the production capacity of our vacuum furnace and fully [optimize] this process. The extreme and demanding rapid heating and cooling cycles called for a unique convection furnace design."  

"I have known Nic for many years, including the Cleveland Chapter of ASM International where we both served as officers – and was honored to nominate him to the Heat Treat Today's 40 Under 40 Class of 2020," comments Rosanne Brunello, director of sales at DELTA H. "The process here was a challenge, but our CTO, Richard Conway, answered the call with an innovative and unique furnace design."

Heat Treat Capabilities “Take Off” at Edwards Air Force Base

/ AEROSPACE HEAT TREAT, ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS

HTD Size-PR Logo

Edwards Air Force Base, an historic airfield engaged in experimental aviation, is expanding its heat treat capabilities with two dual chamber furnaces.

DELTA H® delivered the two Defender Series dual chamber aerospace heat treating (DCAHT®) systems. These systems were developed for specific requirements of the armed forces; they meet the pyrometry standards of USAF/NAVAIR Tech Order 1-1A-9 and qualify to SAE AMS2750G.

Defender Series are "deployable" and has stackable chambers that can be configured with 500°F, 1200°F or 2000°F maximum temperatures as either dual or single chamber systems. They serve as "universal heat treating systems" for hangar sheet metal back shops that are tasked with “keeping them flying” – and are “mission essential” equipment. In addition to Edwards AFB, these systems are located at Texas and Kansas Air National Guard facilities as well as Beale AFB in Northern California to date.

Härtewerk Chemnitz GmbH, a large German commercial hardening plant (Lohnhärterei), has purchased a horizontal, two-chamber furnace low-pressure carburizing and oil quenching system from an international heat treat solutions provider. In the German plant, the integral quench system will replace legacy atmosphere technology and expand their capabilities for mass-producing parts.

This is the first SECO/WARWICK furnace equipped with vacuum heating at the heat treater's German plant and the first Super IQ solution in Germany. The system has a heating chamber, loading and unloading vestibule, and a quenching bath. The equipment in the system enables users to perform a variety of heat treatment processes, heat, and chemical treatment, as well as low-pressure carburizing and quenching.

"The machines we have worked with so far had required time-consuming and expensive preparation, especially when the equipment was not at the right temperature," commented Kai Werlitz, technical operations manager at Härtewerk Chemnitz GmbH. "The Super IQ furnace that we have ordered eliminates not only these difficulties but also enables efficient heat treatment with very high repeatability and uniformity of the carburized layer, which with atmospheric furnaces was only possible to a limited extent."

The heat treater's Chemnitz and Chomutov plants provide a wide range of services related to metal heat treatment and focus on Germany and Europe's mechanical engineering, automotive, and metalworking industries.
