Lindberg/MPH ships box furnace with automated load table to the aerospace industry

Lindberg/MPH, Riverside, MI, announced the shipment of a rod overbend box furnace with an automated load transfer table to the aerospace industry. This furnace will heat-treat parts under an inert atmosphere.

The heat-treating furnace has a maximum temperature rating of 2,000°F and a load capacity of 6,000 lbs. It features a workspace of 36” W x 96” D x 36” H and is designed for a nitrogen atmosphere. A nitrogen gas flow meter controls the atmospheric conditions.

The box furnace includes an automated load transfer table. Under the table, five fans with a variable-frequency drive provide accelerated cooling. The load table utilizes a pusher/puller mechanism to move parts trays in and out of the furnace.

The furnace’s radiant heating system uses heavy-gauge alloy rod over-bend heating elements mounted along the side walls and the floor. Two Watlow F4T controllers control and record the furnace temperature, allowing for seven zones of heating. The box furnace also meets Class 3 temperature uniformity of ±15°F at 1,000°F – 1,800°F.

One Minute Mentor: vacuum furnace setup

A simple but most effective and very flexible vacuum furnace setup, the single-chamber furnace, consists of one chamber in which the workpiece is both heated (convectively, through vacuum heating) and cooled. Cooling or quenching is accomplished by a closed-loop cooling system.

The pressure vessel is filled with inert gas. This gas is circulated inside the chamber, blowing the inert gas across the workpieces to pick up heat and for further recooling across an internal or external heat exchanger. In order to quench rapidly enough to obtain the desired microstructure of tool steels in various sizes and shapes, it is necessary to increase the pressure and/or flow patterns of the quench gas (usually nitrogen). This is accomplished by high-velocity, high-pressure blowers that have reported cooling gas pressures of up to 20 bar. Turbine powers up to 450 kW are necessary to handle these quenching processes.

Ipsen completes ISO/IEC 17025:2017 accreditation for pyrometry services

Ipsen, Cherry Valley, IL, has successfully achieved ISO/IEC 17025:2017 accreditation for calibrations, enhancing its pyrometry services. This accreditation is particularly significant for customers operating under the National Aerospace and Defense Contractors Accreditation Program (NADCAP) and Aerospace Material Specifications (AMS) 2750G.

A key update in AMS2750G, revised in 2022, mandates that calibration service providers must hold ISO/IEC 17025:2017 accreditation. This requirement encompasses temperature controller calibration, system accuracy testing (SAT), and temperature uniformity surveys (TUS).

Cavan Cardenas, Ipsen’s calibration and pyrometry coordinator, emphasized the importance of this certification: “Obtaining this lab certification reassures our customers of our capability to accurately conduct these tests. It’s crucial for us to verify the precision of our calibration equipment to provide superior support to our clients.”

Ipsen has appointed a dedicated technician for its Calibrations Lab, located at the Vacuum Technology Excellence Center in Cherry Valley, IL. This addition strengthens the company’s commitment to providing advanced calibration solutions.

Medical implant hardening in a SECO/WARWICK furnace

SECO/WARWICK, Meadville, PA, announced that they will supply a Vector vacuum furnace to the Marle Group, a global manufacturer of orthopedic prostheses. The furnace on order will be used for the heat treatment of cobalt implants. Cobalt alloy hardening requires very high temperatures, and the heating process for these materials require a high puriity environment, temperature uniformity and very fast and effective cooling.

In order for cobalt alloys to be used in implantology, they must be deprived of their ferromagnetic properties. This shiny, hard metal loses this property only when it reaches a temperature higher than 1131°C. Such a high temperature makes it necessary to use a vacuum furnace in the implant production process. The furnace can not only provide such a temperature, but also guarantees its maintenance over a longer period of time. As a comparison, the temperature, above which a ferSECO/WARWICK, Meadville, PA, announced that they will supply a Vector vacuum furnace to the Marle Group, a global manufacturer of orthopedic prostheses.

One Minute Mentor: Distortion in Tool Steels

Distortion in tool steels encompasses all irreversible dimensional changes. There are two main types: size distortion and shape distortion. Size distortion involves expansion or contraction in volume or linear dimensions without changes in geometrical form. Shape distortion entails changes in curvature or angular relations, as in twisting, bending, and/or nonsymmetrical changes in dimensions. In most cases both types of distortion occur during a heat-treatment operation.

Some of the main interactions occur between temperature, microstructure, and stress/strain. Especially for tool steels these interactions are mainly influenced by the carbon content in the steel matrix, the types and relative amounts of the alloying elements, and the carbide formation/transformation/precipitation characteristics of the alloy system.

Lindberg/MPH ships mesh belt conveyor furnace for use with powdered metal

Lindberg/MPH, Mich., has announced the shipment of an electrically heated, full muffle, mesh belt conveyor furnace. This furnace is designed for treating pressed powdered material.

The furnace is designed for applications with a maximum process temperature of 1000° C (1832° F) that utilize a nitrogen or clean dry filtered air process atmosphere. The unit is configured with 9 temperature control zones and includes a water-cooling section. The conveyor system features a 14 inch wide mesh belt with belt stop alarm to provide an audible and visual indication in case of a conveyor stoppage.

There are purge chambers at the entrance and exit of this conveyor furnace. In these chambers purge gas flows from perforated plenum chambers above and below the belt and exhaust stacks with adjustable butterfly valves are located at the inner ends of each chamber. Load and unload tables at the entrance and exit of the conveyor provide ease of product transfer for the operator.

The furnace zone temperatures are controlled by Eurotherm controllers. These controllers have advanced PID control with variable overshoot inhibition. A hi-limit Eurotherm controller guards against over temperature conditions in each zone of temperature control.  A visual and audible alert and removal of power to the heating element occur in the event the monitor temperature exceeds a desired set point.

One Minute Mentor: Vacuum Furnaces

The demands on vacuum-hardening technology have changed in recent decades. One of the most important considerations that must be met is the accomplishment of highest dimensional stability with optimal microstructural properties and minimal change of the surface of the workpieces. 

Minimizing exposure to air during the heat treatment by reducing the quantity of oxygen in a heat treatment furnace, as with creating a vacuum, is an excellent method for preventing changes in surface appearance and chemical composition.

Suppliers of modern vacuum furnaces are further faced with new demands, such as increasing quenching speed to improve microstructural and mechanical properties by reducing grain size, and enhancing hardness and toughness and/or reducing distortion due to the hardening process. Furthermore, quality standards such as AMS 2750d or North American Die Casting Association (NADCA), which describe temperature homogeneity or quenching speeds and resulting and needed workpiece properties, had a significant effect on furnace design and process control.
