Concepts for channel induction furnaces.

Channel induction furnaces for aluminium smelting are featured by high power flux density, and place particularly high demands on the refractory material. Because of the high flow speeds – particularly in the area around the inductors – the installed materials must exhibit very high abrasion resistance.
Here, Refratechnik uses top quality microsilica-free castables, which not only meet this requirement but also prevent corundum formation on the refractory material.
