EndoFlex generator chosen for fastener heat treatment

UPC-Marathon, Quebec,, a Nitrex company, has commissioned a 100 M3H EndoFlex endothermic gas generator for a South American manufacturer of industrial fasteners.

This is a repeat customer that has UPC-Marathon‘s gas panels, flowmeters, oxygen probes, and Protherm plant automation software installed in their heat treatment operations. With the addition of the EndoFlex generator, they will now be able to supply gas to a new continuous mesh belt neutral hardening furnace for the treatment of metal fasteners used in automotive applications.

The customer had the option to choose between a nitrogen-methanol system or an endothermic gas generator for their neutral hardening furnace. After careful consideration, they selected UPC-Marathon’s EndoFlex generator in order to achieve better control and consistency of the process atmosphere. The result is an improved hardening process and higher-quality hardened fasteners, along with reduced operating costs. The EndoFlex mixes ratios more accurately and efficiently, ensuring a constant furnace atmosphere and consistent gas quality, leading to immediate cost savings through reduced electricity and gas consumption and zero waste.

The system was started in March 2023, and its consistent performance has exceeded the customer’s expectations.

One Minute Mentor: Continuous Operating Furnaces for Tool Steel Strips

The continuous heat treatment of tool steel is applied to low- or medium-alloyed carbon steel strips as well as martensitic stainless steels. The described lines produce high-quality strip with respect to uniform structure, flatness, and bright surface finish. Steel grades with 0.4 to 1.2% C, low and high alloyed, can be processed. Strip dimensions range between 10 to 750 mm (0.4 to 29.5 in.) wide and 0.05 to 4 mm (0.002 to 0.16 in.) thick. High quenching rates are necessary, especially for plain carbon steels. Cooling gradients of up to 600 K/s are possible in a molten lead-bismuth quench. Because two-stage quenching technology provides considerable advantages over quenching in oil, this method has been adopted worldwide. It is also possible to achieve isothermal transformation to bainite and pearlite using a molten metal quench, so this type of hardening and tempering line is extremely versatile.

The configuration of a high-performance line involves an entry and exit section of the strip handling equipment (Fig. 10). The hardening section consists of the austenitizing furnace, the molten metal quench or hydrogen quench, and a martensite cooler. Beyond the martensite cooler the strip is martensitic and fully hardened, and then it passes through the tempering section—consisting of a leveling furnace, tempering furnace equipped with an atmosphere recirculation system, and an atmosphere jet cooler—to finally leave the facility, completely flat, with a bright surface finish and tempered to very uniform tensile strength.

Leading die manufacturer adds Seco/Vacuum furnace to increase capacity

Seco/Vacuum, Meadville, Pa., has announced that a U.S.-based international manufacturer has placed an order for a Vector high-pressure gas quench furnace. The new furnace will increase the partner’s heat treat capability while improving part quality. The Vector will allow the partner to heat treat larger parts, at higher quantities per cycle than their existing furnace, all with improved quality control and reliability.

The partner’s equipment requires the use of large dies that require precise heat treating. Their current heat treatment setup includes a pair of vacuum furnaces, which have some limits compared to the Vector they are about to receive.

The new furnace, a bottom loading Vector vacuum furnace with 6 bar nitrogen gas quench, has a 60″ diameter, 72″ tall, and a 3-ton capacity working zone. It is equipped with convection heating which allows them to run their tempering cycle in the same furnace without having to move parts after hardening, a tremendous time and labor savings.

The furnace is also equipped with SECO/WARWICK’s FineCarb low-pressure carburizing system for future process developments. The Vector will increase production capacity to meet the rising market demand of today and tomorrow. The new furnace’s vertical configuration and rotary hearth were built specifically to accommodate more large dies, allowing the partner to meet the elevated demand with ease. SECO/VACUUM’s intuitive process controls ensure greater heating uniformity than their existing equipment in both convection mode and in vacuum mode.
