High Temperature Kilns and Furnace Considerations

Guys who’ve been doing ceramics for decades tend to call everything a kiln. Back in the day you could point to some differences between a ceramic kiln and a high temp furnace used for metallurgy. A Kiln had a slow heat-up, a soak period, and a slow cool-down that minimized thermal shock to what were usually thermally sensitive ceramic materials.Read more ›

Sintering Furnace Selection Considerations

High-temperature sintering furnaces  are utilized in powder metallurgy for sintering stainless steel and, in some cases, iron-based materials. They are exclusively used in refractory-metal fabrication of molybdenum, tungsten and rhenium. High-temperature sintering furnaces are also utilized in the nuclear-fuel industry for sintering uranium oxide. The ceramic industry has always used high-temperature processes for sintering, co-firing and metallizing. To properly select andRead more ›

Production Furnace Throughput Defined

It is very common in several industries to discuss the output of a continuous furnace in terms of pounds/hour. This is an interesting number and easy to understand, however, it is misused most of the time. The origins of this output rating came from lower-temperature furnaces, specifically traditional mesh belts. If you were to speak with the belt manufacturers themselves,Read more ›

High-Temperature Sintering Furnaces for Production

For production sintering operations, certain furnace design considerations are common regardless of whether you are working in metals, ceramics, or glass and regardless of what industry you work in. In order to achieve compression without liquefication, accurate temperature control and careful atmosphere monitoring are essential to uniformity and throughput. Furnaces for normal sintering applications are often continuous-belt furnaces like ourRead more ›

Nuclear Waste Disposal Facilitated by Glass Melting Furnaces.

In the latest technological solution to a decades old problem, researchers have determined that using blast furnace slag through a process called vitrification, can reduce the volume of radioactive material by 90%. This astounding breakthrough in nuclear fuel disposal melts waste down into little cubes of glass making it way easier to dispose of. The current treatment method for non-compactableRead more ›

Bring Heat Treating Capability to your Machine Shop

If you are one of the thousands of machine shops or prototype houses throughout the country that is routinely outsourcing their heat treatment work to expensive labs with long lead times, we have a suggestion for you:  Consider bringing your heat treating capabilities in-house.   Some of the more common processes that machine shops outsource include: Hardening or Tempering ofRead more ›
