Nitrex secures largest order In company history

Nitrex, Quebec, announced the receipt of a multi-million-dollar contract to provide a turnkey automated nitrocarburizing installation exclusively designed for the production of brake components for electric passenger vehicles.

Under the contract, Nitrex will design, manufacture, commission, and test two cutting-edge continuous-line furnaces capable of processing millions of brake parts annually. The NXL furnace series, with its automation capabilities and continuous flow-through design, precisely meets the supplier’s requirements for improved process efficiency and optimized production.

In addition to the advanced furnace design, Nitreg®-C and ONC® technologies are integral to this order. This ferritic nitrocarburizing process with post-oxidation improves metal corrosion resistance and effectively reduces rust formation. It is the right solution for staying ahead of changing industry standards and achieving lower non-effluent emissions associated with electric vehicle braking systems.

The turnkey installation, combined with Nitrex’s skilled R&D team, who craft and develop process recipes for optimal results, further distinguishes the company. Through its holistic approach, Nitrex delivers solutions that set it apart in the industry and reinforce the supplier’s choice to partner on this transformative project.

One Minute Mentor: Indirectly heated fluidized-bed furnace

One Minute Mentor: Indirectly heated fluidized-bed furnace

Most fluidized-bed furnaces are used at temperatures below 1095 °C (2000 °F), although some manufacturers have furnaces capable of treating components to temperatures through 1205 °C (2200 °F). Initially, the gas flows upward through the permeable base to agitate the particles as the pressure is gradually increased. (b) Eventually, the gas flow is sufficient to lift the small particles of refractory materials and to transform the particle movement into a violent turbulent motion.

In the early 1980s, this furnace technology seemed to be on the right track as an alternative to salt bath technology, showing similar advantages and applications but without the environmental hazard of salt compounds, waste disposal, recycling of salts, and so on. Nowadays it can be concluded that salt bath technology was partially substituted by vacuum technology, but especially for bainitic hardening (austempering processes), salt baths are still commonly used and show a slightly growing tendency, whereas fluidized beds are hardly used any more.

This temperature limitation is related to the wear and tear on the retort materials at high temperatures, which was one of the reasons for the reduced interest in this furnace type after the initial hype.

Lindberg/MPH completes roller hearth furnace system for the energy industry

Lindberg/MPH, Mich., announced the installation of a roller hearth furnace system for a manufacturer of products used in the energy industry. The heat treat system is comprised of two box furnaces with quench tanks, a dual directional load transfer car, four companion draw batch ovens, and two stationary load/unload tables.

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

Wisconsin Oven to ship three custom conveyor ovens to the molded-fiber industry

Wisconsin Oven, East Troy, is scheduled to ship three custom dryers to a manufacturer in the molded-fiber industry. The ovens will be used for drying thick-walled paper pulp molded fiber packaging material used in a variety of products. Molded fiber packaging is made of 100% recycled materials, making them an environmentally friendly solution for companies looking to use sustainable packaging and reduce their environmental impact.

These paper pulp drying conveyor ovens are designed with four temperature zones, and each has the sufficient capability to remove 850 pounds of water per hour from the molded pulp. The ovens feature a maximum temperature rating of 500°. The work chamber dimensions are 8’ W x 120’ L x 1’ H. A total of twelve personnel access doors with explosion relief latches are located on the sides of each unit. Each unit also has stainless steel sheet metal and structure on the wet end to reduce corrosion.

The conveyor ovens are designed with top-down and bottom-up airflow to maximize the drying rate of the paper pulp shapes. The flat wire belt continuous conveyor system uses a variable frequency drive that is adjustable from 0-3 FPM. Emergency stop buttons are located at the load and unload sections of each oven for operator safety.

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: Fluidized Bed

One Minute Mentor: Fluidized Bed

A fluid bed results when a gas is passed upward through a bed of small solid particles at a rate fast enough to lift these particles and to create turbulence. This motion of particles, which are usually made of aluminum oxide or silica oxide, is similar to that of a fluid, which can be seen schematically in the figure.

When gas is forced upward through small holes in a supporting plate, two forces meet to raise the particles: the buoyancy of the gas and the retarding force known as aerodynamic drag. Objects to be heat treated are immersed directly into the bed of particles.
