How to weld a metallic heating element
Welding is an excellent way to increase efficiency, improve forming and strengthen your heating elements. But there is lots to consider for element welding; from which material to use for terminals, to how to weld terminals onto the metallic elements. In this video, our welding expert ChristerEverything you need to know about electric furnace maintenance
Do electric furnaces need maintenance? Although minimal, yes indeed, and there are a few key things to think about. Together with Stephen Smee, our material expert Torbjörn walks us through everything you need to know about how to service an electric furnace to keep it hot and well for as longHow to form a coiled heating element
Are you curious to know how to make a coiled heating element, why nichrome is non-magnetic, or why the same heating wire can have different color? Welcome into our element workshop where we meet Stephen Smee and Kanthal material expert, Torbjörn Frankén who walk us through everything youOptical fibers
In the manufacturing of optical fiber, sintering is a key process where the heating solution utilized affects the quality of the end product. This is because sintering is done in a controlled atmosphere and having precise control over the heat input and temperature, which Kanthal’s electric
Foam glass
With its focus on recycling glass and turning it into insulation, the foam glass industry is already on the right path. Still, CO2 emissions are prominent because of the common use of gas burners which offers poor thermal efficiency at around 30 percent – compared to 90 percent thermal
Finding the right heating solution for glass tempering furnaces
For glass tempering furnaces, temperature control over different heating zones is crucial, and Kanthal can deliver solutions for precise heat and reliability.
