Furnace Concepts Inc.

ceramic radiant tubes from furnace concepts are available in a variety of materials which can be used in many high temperature shielding and immersion applications. typical compositions are listed below. cermet radiant tubes -1700°c
silicon carbide radiant tubes- 1500°c
sicrad radiant tubes- 1300°c sicrad immersion tubes for aluminum and glass excellent thermal shock resistance maximum use temperature 2400° f non-wetting low porosity the sicrad material from furnace concepts is a cast ceramic material, which is fired at elevated temperature. Because of its excellent thermal shock resistance and high thermal conductivity it is an excellent material for use as immersion protection and radiant tubes for use in many molten materials. as thermocouple protection tubes the material offers excellent thermal conductivity, which allows the optimum temperature measurement. Sicrad also exhibits a resistance to abrasion and wetting by molten metals.
when used as a radiant tube for electric and gas heating the sicrad offers the same characteristics as mentioned above coupled with the ability to uniformly distribute and efficiently dissipate the energy from the heat source to the molten bath.
