Support for metal screens or heaters in high temp. furnace - esp. where ceramic profile is used to carry resistance heater elements, and also to clamp ceramic fibre linings in furnace

摘要

The support includes a U-shaped strap welded to the inside surface of a furnace wall. The web (16) of the strap is used to locate a row of metal rods (18) clamped to a support (20) employed to compress several layers of fibre linings against web (16). The support (20) includes a row of hooks used for the suspension of metal parts, esp. electic resistance heater elements inside the furnace. Rods (18) pref. have a length avoiding the use of a noble metal for web (16); and support (20) is pref. made of ceramic, and may be located in a brick lining. Used in heat treatment furnaces in which a ceramic fibre lining reaches 1300 deg.C.
