Nitrex provides nitrocarburizing system to New Zealand heat treater

Nitrex, Quebec, has announced that they have provided a nitrocarburizing system to Heat Treatments, a leading provider of commercial heat treatment services in New Zealand and one of Nitrex’s earliest customers.

Heat Treatments’ partnership with Nitrex dates to 1992 when they purchased its first Nitrex system with Nitreg nitriding capabilities. As operations grew, the company later added a second system in 2004 for nitrocarburizing and post-oxidation treatments. Contrary to the first two systems, which are identical pit furnaces, the latest addition, an NXK series, features the furnace and control panel mounted on an integral platform. Delivery, installation, and startup time and costs are reduced with this design. The NXK-812 model is designed to treat workloads weighing up to 1200 kg, with a diameter of 800 mm (31.5″) and a height of 1200 mm (47.25″). The system is equipped with advanced process technologies, including Nitreg-C controlled nitrocarburizing and ONC post-oxidation, which provide precise control and consistent results.

One Minute Mentor: Plasma Nitriding Equipment

One Minute Mentor: Plasma Nitriding Equipment

Cold-walled (double-walled water-cooled) systems were the first generation of plasma nitriding furnaces. This technology is also a vacuum-based process but employs the principle of glow discharge to provide energy for heating and nitriding at one time. Therefore, the independent control of the temperature stability and the nitriding intensity is not possible because both processes are using the same energy source—the plasma.

The hot-wall plasma nitriding furnaces, the next generation of cold-wall ion nitriding systems, are mainly used and built now. This system ensures optimal nitriding quality by fulfilling the highest demands on temperature and nitriding process control. The big advantage of this technology is the separation of the control of the heating and the plasma nitriding parameters. The heating and temperature control of hot-wall plasma nitriding furnaces is realized by several independent heating/cooling zones, which guarantees optimal temperature homogeneity

Evolution on the microstructure and mechanical properties of a new multicomponent near-Alpha Titanium Alloy after rolling and heat treatments

Beijing University of Technology, China, presented the microstructure and mechanical properties of a new type of multi-component near-α titanium alloy sheet after rolling, 700°C aging, and 800°C aging in a new paper.

 The results show that the strength of the alloy after aging at 700°C increases from 1156 MPa to 1304 MPa, respectively, but decreases to 1246 MPa with the aging temperature increasing. The ductility of the alloy aged at 700°C is lower than that of the rolled state, but the ductility increases slightly with the aging temperature increasing. The effect of aging heat treatment on the microstructure and precipitation behavior of alloy plates has been studied and compared with alloys before aging. 

After heat treatment, the content of primary α decreases from 25% to 5%, respectively. Two kinds of silicide precipitate at different positions, with the large-size spherical silicide being (Ti, Zr, Nb)5Si3, and the small-size fusiform silicide being (Ti, Zr, Nb)6Si3, respectively. Ti3Al was precipitated in the primary α phase, during the aging process. The silicides exhibit the strengthening effect on the alloy, but the effect weakens when the silicides grow up. The loss in ductility is mainly attributed to the precipitation of the α2 phase after aging treatment. However, ductility is improved after applying higher aging temperatures as the size of the α2 phase becomes smaller, and the distribution of them tends to become dispersed.

Lindberg/MPH ships rod overbend box furnace to the manufacturing industry

Lindberg/MPH, Mich., has announced the shipment of a rod overbend box furnace with powered load/unload table to the manufacturing industry. This heat-treating furnace has a maximum temperature rating of 2000°F and a load capacity of 900 lbs. 

The workspace dimensions of the furnace are 24” W x 36” D x 18” H and it is designed for air atmosphere applications. The box furnace features an automated actuator to flip the push/pull mechanism on the load table to eliminate the operators need to manually flip it into push position. This option allows the push/pull head to retract from the furnace once the work grid is in the furnace chamber and increase operator safety by removing the need to reach into the hot furnace with a hook to flip the push/pull head and.

The furnace chamber is heated with a radiant heating system the utilizes heavy gauge alloy rod over-bend heating elements mounted along the side-walls and the floor. The furnace temperature is controlled by an Allen Bradley ControlLogix Programmable Logic Controller that includes digital setpoint and display. A Honeywell DC2500 high limit controller disconnects the power to the heating elements and sounds an audible alarm if the temperature exceeds desired set-point.

A ‘green’ Seco/Warwick vacuum furnace for wind power plants

Seco/Warwick, Meadville, Pa., has been chosen by a recognized manufacturer of wind power plants to deliver a vertical vacuum furnace designed to perform low-pressure carburizing for the large structural elements (gearboxes) used in wind power plants. 

The solution on order combines the advantages of two technologies: atmospheric and vacuum processing. The furnace is designed for low-pressure carburizing oversized parts, made possible due to a very large, vertical heating chamber, while the furnace pit structure saves space in the production facility. The Pit-LPC technology is a modern alternative to atmosphere carburizing. Its main advantage is the ability to carry out efficient and effective carburizing in a much shorter time than in atmospheric furnaces. The vacuum processing solution provides more than twice the productivity, and consequently lower process costs and a quick investment return.

The main advantage of this furnace is the ability to open the furnace at process temperature at the end of the cycle. This is the advantage of atmospheric furnace technology implemented within a vacuum furnace. This type of solution combines the advantages of an atmospheric furnace with the advantages of a vacuum furnace, which include: elimination of the oxidation effect at the grain boundary, process purity, and heating uniformity. The product solves the problem of high energy and process gas consumption by the partner’s old furnaces, and shortens the carburizing process, which significantly improves efficiency and production costs.
