ALD develops a new powder recycling process for a sustainable circular economy

ALD Vacuum Technology, Germany, has developed an additive manufacturing solution, the EBuild 850 that can process powder with a wide distribution, enabling it to be used not only in industrial-scale part production, but also in powder recycling efforts. 

Using selective electron beam melting to create powder-filled ingots, ALD achieves an unprecedented build rate of over 1000 cm³ per hour. These ingots can be seamlessly converted into new powder, for example in ALD’s EIGA Premium systems, promoting a sustainable circular economy.

ALD’s approach not only reduces waste, but also offers versatile options for downstream processes. The powder-filled solid cased ingots are much safer to handle and process than loose powder. This flexibility increases the overall efficiency of the recycling process and enables integration into established processing routes.

By adopting ALD’s innovative approach, industries can now achieve economical production while contributing to a circular economy. ALD remains committed to driving sustainable practices within the industrial sector, paving the way for a greener future.

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.

Wisconsin Oven ships two horizontal quench systems to the semiconductor industry

Wisconsin Oven, East Troy, WI, announced the shipment of two Electrically Heated Horizontal Quench Systems to the semiconductor industry. These systems are designed for the annealing and rapid cooling of various high purity alloy parts.

The operation of each horizontal quench system begins with loading the product onto a work grid located on the loading platform. After the load is lifted into position, a pusher/extractor mechanism at the front of the quench tank moves the load onto the quench lift platform. Then, the furnace pusher/extractor mechanism transfers the load into the furnace for annealing. Once the heating cycle is complete, the vertical lift door opens, and the furnace pusher/extractor moves the load back onto the quench lift platform, lowering it into the water quench tank for cooling. After adequate cooling, the quench lift raises the load, and the front-mounted pusher/extractor mechanism returns it to the scissor lift, where a blow-off system removes most of the water from the load. A video demonstrating this system’s operation is available through a provided link.

Each horizontal quench furnace can reach a maximum temperature of 1,250°F and has the capacity to heat and support a 4,500-pound gross load. These furnaces are designed to achieve a temperature uniformity of +/-10°F. The customer requested a uniformity tolerance of ±20°F at 500°F, 900°F, and 1200°F, which was documented for each system through a nine-point profile test conducted in an empty oven chamber under static conditions.

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.
