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.

Ipsen ships Turbo Treater vacuum furnace to commercial heat treater in Mexico

Ipsen, Tainan City, Taiwan, has shipped a vacuum furnace to Tratamientos Termicos Avanzados (TTA) in Mexico. Translated to “Advanced Heat Treatments,” TTA is a leader in plasma nitriding services for steel. They serve many industries and boast a clientele that includes John Deere, Caterpillar and Nissan.

Looking to expand their capabilities by adding vacuum processing to their commercial heat-treating business, they chose an Ipsen Turbo2Treater for its process flexibility. The new furnace has a work zone size of 24” x 24” x 36”, 1,600 lb. weight capacity, 2,400 °F maximum operating temperature, and quench pressure up to 12 bar. It will mainly be used for hardening tool steels but can easily be adapted to meet new customers’ needs.

TTA chose Ipsen for their ability to lead them in the right direction to grow their business.

Nitrex and Linde renew their 13-year collaboration

Nitrex, Quebec, and Linde are celebrating their 13-year collaboration, which today covers Europe and North America. Nitrex said that this partnership emphasizes both companies’ positioning in terms of technology, digital, and green footprints. 

The cooperation between Linde (previously Praxair) and UPC-Marathon, a Nitrex company, began in the USA in 2010, when Linde approached UPC-Marathon to build gas panels. Eventually, the company started sending some of its clients who needed technical support in UPC’s direction.

Nitrex supplies Linde with equipment and analyses to control gas atmospheres, thanks to its competence in heat treatment and electrical fields, technical solutions, support, and world-class gas panels.

One Minute Mentor: Controlled Atmosphere Furnace Equipment

Heat treatment of tool steels usually requires high flexibility combined with small lots of parts. Seal quench furnaces, executed with a single heating chamber, meet this demand. Figure 5 shows a typical schematic of a single-chamber furnace, executed with a pre-chamber, which is used both for loading and unloading and also for oil quenching or gas cooling. Another execution is shown in Fig. 6, where the load is fed directly into the heating chamber (left side in the drawing). In this case the load is transported through the furnace and received after oil quenching on the right-hand side.

Wisconsin oven completes spray quench aluminum solution furnace for the defense industry

Wisconsin Oven, East Troy, Wis. announced the completion of a Horizontal Spray Quench Furnace for C/A Design located in Dover, NH. This furnace will be used for the solution treatment of aluminum. The system is designed to soak the product load at temperature in the furnace and then a pusher mechanism rapidly moves the load into the spray quench. The spray quench offers reduced distortion in comparison to submersion quenching.

The maximum temperature for this system is 1,150°F and it has sufficient capacity to heat a 200 pound aluminum load plus the work grid and product fixture. A temperature uniformity survey was documented for +/-10°F at 985°F to verify the furnace has the capability to meet AMS 2750G, Class 2 furnace and Instrumentation Type D requirements.

The spray quench is located in front of the oven and has vertical-lift, pneumatically operated doors on each end. The spray quench system utilizes fifty (50) fine mist nozzles located above, below, and on each side of the quench chamber to rapidly cool the product from all sides. Each nozzle is independently selectable from the touchscreen HMI and a variable frequency drive allows the pump speed to be adjusted to maintain a constant pressure to each spray nozzle.

Lindberg ships full muffle mesh belt conveyor furnace to manufacturing industry

Lindberg/MPH, Mich,  a leading manufacturer of heat treat furnaces, announced the shipment of a continuous full muffle mesh belt conveyor furnace to an industrial manufacturer.

This conveyor furnace is designed for applications with a nitrogen atmosphere and a maximum temperature of 1,100°C. Additionally, the furnace has a hydrogen flow meter and combustible gas system so the customer can run a hydrogen atmosphere when needed. The combustible gas system provides a timed nitrogen gas purge of the muffle before process gas can be introduced into the furnace muffle. The conveyor furnace has overall dimensions of 128” L x 22” W 41.5” H. There are tables at both ends of the furnace for loading and unloading of the product. The unit is designed with four (4) temperature zones and a water-cooling section that parts travel through prior to exiting the chamber.

OMM: Controlled Atmosphere Furnaces

In the past, atmospheric furnaces were used quite often for heat treatment of tool steels. Due to the improved furnace technology of vacuum furnaces and their increased distribution in the market, the percentage of tools heat treated in atmospheric furnaces has fallen significantly over the last 20 to 30 years.

Furthermore, most of the atmospheric furnaces show a maximum temperature of 1100 °C (2000 °F). Therefore, the application of atmospheric furnaces is limited, with the maximum hardening temperature of the tool steel at or below 1050 °C (1925 °F).

However, for atmospheric furnaces it is essential to select an atmosphere that will protect the surface of the tool steel against the addition or the depletion of carbon during heat treatment. Therefore, it is desirable to choose one that requires no adjustment of composition to suit various steels. Ammonia-based atmospheres meet this requirement due to the ammonia dissociation at high temperatures, leading to an excess of hydrogen with the advantage of a sufficient reduction of oxidation even of high-chromium steels.
