NITREX METAL TO SUPPLY NITRIDING SYSTEM IN CHINA

An American automotive parts manufacturer has recommissioned Nitrex Metal (Montreal, Canada) to supply a fully automated nitriding system for their newly-constructed production facility in China. The company first ordered a Nitrex system for installation in their USA-based plant in 2006, and the follow-on order will help the company to meet increasing global demand for its automotive pump components. The furnace has a usable work zone of Ø 31.5” by 59” H (800 mm x 1500 mm) and a gross loading capacity of 3300 lbs (1500 kg). The system is supplied with a fully automated control system, Nitreg® nitriding control technology, and a pre-programmed recipe with optimized process parameters for greater consistency and repeatability. The system is scheduled for delivery in June 2007.

Combustol Brazil Expands Nitriding Capacity

Combustol’s Sao Paulo, Brazil service center has expanded its commercial heat treatment capacity with the addition of a BTQ-669 horizontal batch nitriding furnace. The Nitrex engineered system, which has been on-stream since the start of the year, is equipped with the Nitreg®-C technology for nitrocarburizing pneumatic components for a major automotive supplier. The new furnace was installed alongside two existing Nitrex nitriding pit-type furnaces and will increase Combustol’s nitriding/nitrocarburizing capacity to approximately 7500 kg (16,500 lbs) per day.

Nitrex Supplies Nitriding System for Extrusion Dies

Nitrex Metal Inc. has installed a turnkey nitriding system at Erbslöh Aluminium GmbH. The system is fully automated and preprogrammed with Nitreg® technology to accurately nitride aluminum extrusion dies. The equipment includes a 31.5” Ø by 43” H (800 mm by 1100 mm) furnace with vacuum purge, a water cooling system, an ammonia station, and an IN-65 effluent neutralizer. Erbslöh decision to move to in-house nitriding, previously outsourced, was fueled by the need for better quality and consistent results of treated dies. The new installation came on stream at the Velbert, Germany plant the third quarter of 2006.

Nitrex Supplies Nitriding System for Pump Components

Nitrex Metal Inc. installed a Nitreg® nitriding system at a large US manufacturer of automotive pump components. The furnace has a usable work zone of Ø 39.5” by 79” H (1000 mm x 2000 mm) and a gross loading capacity of 7500 lbs (3400 kg). The turnkey system is supplied with Nitreg®, a potential-controlled nitriding technology automated for process repeatability and tailored specifically to the application. Improved product quality and reduced processing time are key advantages of the new installation.

Nitrex Receives Order for Small-Scale Nitriding System

Nitrex Metal Inc. sold its first small-scale nitriding furnace to Hindustan Aeronautics Ltd., an Indian manufacturer of aircraft, helicopters, aeroengines, accessories and avionics. The NX-406 is one of three models available in the series and has a work zone diameter and height of 400 mm by 600 mm (15 ¾” by 23 ½“), with a 200-kg (440-lb) capacity. The furnace is integrated with the control system and shares similar design features as our large-scale furnaces, such as light ceramic fiber insulation for efficient heating, a double-wall Inconel retort, a recirculation turbine for uniform temperature distribution, and an automatic lift cover mechanism. The equipment will be used for nitriding fuel injection components. Installation is scheduled for fall 2006.

Nitrex Completes Two New Nitriding Installations for DANA Group

Nitrex Metal Inc. completed the start-up of a 6000-kg capacity nitriding system for processing ring gears at Dana in Arco, Italy, a facility that manufactures transmission boxes for off-road equipment. This project reflects an interesting technological shift from induction hardening to a lower-cost, high performance Nitreg® controlled nitriding process. Production with the new Nitrex system started in May 2006. The piston ring facility of Dana Automotive Systems Group in Brazil has also increased the nitriding capacity at its Gravataí location earlier this year. The additional 1.5-ton nitriding furnace is engineered to use Nitreg®-S, a special controlled nitriding technology designed for stainless steel applications. Nitreg®-S ensures the uniformity of nitrided case with no distortion following the treatment. The turnkey system also included the integration of an IN-65 effluent neutralizer to meet environmental emissions requirements. In addition to the new installation, Nitrex concurrently upgraded the operating software of the original nitriding system with NPC and NPM; the first is the newest version of the Nitrex Process and Furnace Control Program, the latter is a software utility that links the control system to a central interface at a remote location.

Kęty S.A. Brings Nitriding Operations in-house

Nitrex Metal Inc. successfully completed the installation and commissioning of a Nitreg® nitriding system for Grupa Kety S.A., a Polish manufacturer of aluminium extrusion products in soft and hard alloys. The NX-1015E model has a work zone diameter and height of 39" by 59" (1000mm by 1500mm) and can handle a load capacity of 5,500-lb (2,500-kg). The integral process technology Nitreg® provides an increase of the die bearing hardness and wear resistance, resulting in improved die performance. The company’s nitriding was previously outsourced. By acquiring its own nitriding equipment, Kęty S.A. will now be equipped to manage die-handling operations under one roof with the added benefit of increased production capacity and flexibility. The project was completed in the first quarter of 2006.

ASSAB STEEL TAIWAN expands Value-added Services to Include Nitrex Nitriding

Assab Steels (Taiwan) Co. Ltd, a full service supplier of tool steels offering fabrication as well as machining and heat treating options, has added nitriding to its range of commercial services. The company houses a Nitrex system that runs on Nitreg® and ONC® technologies: the first is a reliable nitriding process for improving the mechanical performance of treated parts, while the second is an in-process post-nitriding oxidation process that has the dual effect of enhancing wear and corrosion resistance. The furnace has a work zone diameter and height of 800 mm by 1500 mm (31.5” by 59”) and can handle a load capacity of 1,500-kg (3,300-lb). Production with the new equipment started in the final quarter of 2005 and is being used for processing extrusion, forging and die-casting dies as well as feed screws.

The first international NITRIDING SYMPOSIUM took place May 26-27, 2005 in Montreal, Qc, Canada. The inaugural event brought together an international audience of 96 academic researchers and industry professionals representing 15 different nations.
