Most vacuum furnaces currently active in the heat-treating world incorporate some form of, or combination of, graphite-felt insulation, with either a foil or board internal facing in the furnace hot-zone construction. The graphite felt used in high-temperature furnaces is either PAN-based or Rayon-based.
Additive manufacturing (part of the better-known 3D-printing process) has become a key technology in many industries over the past few years, from manufacturers producing custom aviation components to toy makers who want to offer flexible designs.
The additive-manufacturing (AM) process as a whole involves turning 3-D CAD files on computers into finished products layer by layer –although AM specifically relates to the construction part of that process. What happens after the printing phase has concluded also matters, however, in order to ensure that products are ready for use.
The recent pandemic forced many companies into survival mode: reducing head-count, cutting costs where possible and establishing new health and safety protocols, all while trying their best to carry on with business as usual. But what about the next crisis?
At the time that I started working on the background for this article, I thought, “I wonder what Wikipedia says about steam?” According to Wikipedia, steam is water in the gas phase commonly formed by boiling or evaporating water. Steam and the steam engine played a central role in the Industrial Revolution, with the modern steam engines generating more than 80% of the world’s electricity.
Commercial and captive heat-treat facilities have significant capital investments in their equipment, particularly in fixtures and fabrications. Many shops have made investments in alloys that have improved life from two years to four years.
Over the past few decades, significant strides have been made to increase the life cycle of components that are to be used at high temperatures. Today, there are new alloys that can result in another doubling (or more) of the component life at far less the doubling of cost.
You could say brothers Frank and Gene Clark followed their father’s lead.
Wade Clark, who had a long and distinguished career in the heat-treating industry, inspired his sons to enter the field. But instead of working in the heat-treat department of a manufacturer or for a commercial heat treater, the brothers opted to forge their own path.
With our diverse editorial coverage, there are a number of associations in our industry. I personally belong to APMI International (MPIF) for powder metals and additive manufacturing as well as AIST (Association for Iron & Steel Technology). That’s in addition to IHEA and MTI, of course.
SimpliVac is the first programmable castable mounting system that will expedite materials sample preparation in manufacturing quality control or inspection laboratories that work on testing small material parts or component samples.
The R60 Series of fixed infrared sensors features a fiber-optic fixed infrared sensor for processes with tight installation spaces, electromagnetic interference or ambient environments up to 392°F (200°C) without cooling.
