In electrical furnaces, performing winding and installing properly are as important as calculating the strength and surface load of resistance. 
Carrier rollers play an important role in the trouble-free operation of the furnace and long wire life.
Teknotherm has been the representative of the company HobCertec about it for a long time. Our ceramic rollers are the most strong and resistant to thermal shocks in the market. They don't sag when ran for a long time. They don't contain iron-oxide due to the rigor in the selection of raw materials. Rollers that contain iron-oxide can be well seen from the red color formed on their surface due to the magnetic zone formed by the resistance. Iron accumulated on the surface will cause the resistance make arc and the furnace to stop operation, hence there will emerge production loss. As the production of carrier rollers in Teknotherm involves laser technology, it also differs from its opponents with its smooth surface and smooth cylindrical structure.
