Spang Power Electronics is a manufacturer of custom power equipment installed throughout the Ceramic Fiber Industry. Spang’s expertise in power control and conversion has helped them become a global leader for the following applications.

Electric Melt Furnace

In modern ceramic fiber manufacturing the batch is melted by electricity. The current is typically injected into the top of the furnace by electrodes. The molten ceramic material itself acts as the heating element conducting electricity between the inserted electrodes (known as Joule heating).

Spang Power Electronics provides SCR Controllers, Transformers, and Power Systems to provide highly accurate controlled power to the electrodes of the melt furnace.

Bushing

In some types of ceramic fiber manufacturing, the bushing section transitions the molten material into the ceramic fiber. A platinum bushing or block is heated and precisely temperature controlled. The bushing typically has a single hole or orifice for the molten material to flow through. Once through the orifice, the material is dropped into a “fiberizer” which, acting like a cotton candy machine, sprays the molten ceramic and creates fibers as the fine strands cool.
