The L&L Special Furnace Co., Inc. model FB435 has an effective work area of 48” wide by 32” tall by 60” deep and has certifiable temperature uniformity of ±10°F from 500 to 1,850°F. Additionally, the elements are very evenly spaced around the chamber and the furnace is lined with ceramic fiber on the sides and top.

The furnace case is sealed internally for atmosphere control, and an inert blanketing gas such as nitrogen is used to displace oxygen present within the work chamber. This provides a surface finish in which oxidization is less likely to form on the part. The atmosphere is delivered automatically through a flow panel by the furnace control.

Tool Manufacturer To Expand Heat Treat Capabilities with Pit Furnace

February 27, 2023 / ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT

A tooling manufacturer is expanding with an electrically heated, steam atmosphere pit furnace for steam treating parts. The steam treating process creates a uniform blue-black finish on the surface of parts, which improves wear and corrosion resistance.

Lindberg/MPH, a manufacturer based in Michigan, shipped the steam treating furnace which has a maximum temperature rating of 1,250°F and work chamber dimensions of 22" diameter x 36" depth. The pit furnace is insulated with vacuum formed ceramic fiber modules that allow for rapid heat up rates and fast control response. A circulation fan distributes heat evenly throughout the chamber which ensures rapid and uniform heat transfer throughout the product load.

“This steam atmosphere pit furnace has the sufficient capacity to process a workload of 1,200 lbs," comments Kelley Shreve, application engineering manager at Lindberg/MPH. "This furnace was also designed with a custom powered lid for ease of loading."

The SCAHT®-HD (Heavy Duty) Series furnaces, from DELTA H®, are set up with Instrumentation Type B and have two load thermocouples. The furnaces have a certified TUS volume of 2 feet wide, 1.5 feet high and 2 feet deep with a maximum continuous operating temperature of 1,200°F. Both are designed to receive baskets of parts from many nearby heat treating operations for secondary heat treatments. Temperature control and data acquisition are provided by Super Systems and feature the SSi 9130 controller/programmer. ATP qualified them as Class 2 (+/- 10°F) from 300°F to 1200°F.

“We were looking for a partner to replace existing tempering furnaces that had become too costly to maintain and could no longer meet required pyrometry standards. Our goal was to install reliable and modern furnaces that were specialized for our small batch/job shop work," said David Reger, president at Winston Heat Treating and a Heat Treat Today's 40 Under 40 recipient.

Heat Treat Brought In House for North American Producer

December 5, 2022 / ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS, MANUFACTURING HEAT TREAT

A North American producer of mining, construction, and material handling products added a continuous quench and temper furnace system as part of a larger plant expansion to bring foreign outsourced manufacturing in house.

Can-Eng Furnaces International Limited's furnace will be part of an automated manufacturing cell and fed automatically from upstream handling equipment. The multizone belt style temper furnace employs high efficiency natural gas-fired heating and recirculation systems. Having the furnace system in house will not only improve part quality but also help eliminate overall shipping costs and reduce supply chain issues.

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.

"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

September 28, 2022 / AEROSPACE HEAT TREAT, ATMOSPHERE AIR FURNACES NEWS, FEATURED NEWS

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.
