MOLYBDENUM DISILICIDE-BASED CERAMIC HEATING ELEMENT HOLDING STRUCTURE

Sandvik KK, Hyogo (JP)

1. A molybdenum disilicide-based ceramic heating element holding structure, comprising:one or more elongated support members arranged to support a molybdenum disilicide-based ceramic heating element having an elongated shape by mounting the molybdenum disilicide-based ceramic heating element at locations along a long axis direction thereof; and
a plurality of first holding members for holding each elongated support member at two or more locations in a long axis direction of each elongated support member,
wherein the plurality of first holding members are held by one or more second holding members or held by a base portion of a holding structure, the elongated molybdenum disilicide-based ceramic heating element being exchangeably mounted on the elongated support member so as to be exchanged without breaking a heating element holding structure,
wherein the elongated support members include a plurality of molybdenum disilicide-based ceramic elements located along a length of the elongated support member, successive molybdenum disilicide-based ceramic elements separated by an electrical insulator,
wherein a location of the successive molybdenum disilicide-based ceramic elements along the length of the elongated support member coincides with a location where the elongated support member supports the molybdenum disilicide-based ceramic heating element, and
wherein, at locations where the elongated support member supports the molybdenum disilicide-based ceramic heating element, the molybdenum disilicide-based ceramic heating element are directly contacted by the molybdenum disilicide-based ceramic elements.
