Abstract
A peripheral seal for a furnace, e.g. a soaking pit, comprising an elongate rectangular section fibre assembly mountable on the furnace roof or door such that a flat face of the assembly can bear on a mating face of the furnace wall, means being provided for advancing the assembly such that the flat face thereof can be maintained in contact with the wall face whereby to compensate for wear and erosion of the fibre assembly.
Claims11
A demountable peripheral seal for sealing an opening between a furnace closure member and a mating furnace wall face, comprising an elongate rectangular-section assembly of ceramic fibre arranged in layers lying in generally parallel planes perpendicular to the length thereof mountable on the closure member and having a flat face arranged to bear on a mating face of the furnace wall when the seal assembly is mounted on a closure member, and means enabling advancement of the assembly perpendicular to its length, whereby the flat face thereof can be maintained in contact with the wall face whereby to compensate for wear and erosion of the fibre assembly.
A fibre seal mountable on the roof of a soaking pit for ingots, said pit including a pit wall having mating faces for said roof, comprising a central supporting rod, an elongate fibre assembly embodying a multiplicity of rectangular-section fibre pads clamped together along said supporting rod and arranged such that a flat face of the pads bears on a mating face of the pit wall, threaded tie links at spaced positions along the length of the rod and extending between adjacent fibre pads, and nuts on said threaded tie links for mounting them on said roof and rotatable to advance the fibre assembly whereby to ensure that the flat face of the pads is maintained in sealing contact with the pit wall to compensate for any wear or erosion of the fibre assembly.
