Curved nose refractory construction

In a high temperature furnace, a suspended curved nose construction having its center of radius exterior to said furnace, comprising:

• at least one radial filler refractory having opposite tread sides converging toward its cold top and a generally planar top, a generally planar bottom, a generally planar front, a generally planar back, a first tread side, and a second tread side, each said first tread side and said second tread side having an equal number of alternating tread ridges and tread grooves, said first tread side and said second tread side being symmetric about a plane passing through midpoints of said top and bottom and perpendicular to said front and said back, and said top has a width shorter than the width of said bottom;
• at least one rectangular filler refractory;
• at least one rectangular hanger refractory;
• each said rectangular filler refractory and each said rectangular hanger refractory having opposite tread sides mateable with said tread sides of said radial filler refractory, each said rectangular filler refractory and said rectangular hanger refractory have a generally planar top, a generally planar bottom, a tread front, a tread back, said tread front and said tread back each having an equal number of alternating tread ridges and tread grooves, said tread front and said tread back being asymmetric about a first plane parallel to and equidistant from the ends of said tread ridges of said tread front and said tread back, a first tread side, a second tread side, said first tread side each having an equal number of alternating tread ridges and tread grooves, said first tread side and second tread side being symmetric about a second plane parallel to and equidistant from the ends of said tread ridges of said first tread side and said second tread side, any combination of said at least one radial filler refractory and said at least one rectangular filler refractory adjacently mated and supported by said rectangular hanger refractory forming at least a section of curved nose construction;
• and suspension means for suspending said at least one rectangular hanger refractory.

In a high temperature furnace, a 90.degree. suspended curved nose construction having its center of radius exterior to said furnace, comprising:

• a plurality of adjacent layers of refractories across the width of said nose, each layer comprising three radial filler refractories having opposite mateable tread sides converging towards its cold top;
• two rectangular filler refractories;
• two rectangular hanger refractories;
• each said rectangular filler refractory and each said rectangular hanger refractory having opposite tread sides of said radial filler refractories, each said radial filler refractory adjacently mated to one said rectangular filler refractory and adjacently mated and supported by one said rectangular hanger refractory, said rectangular filler refractory and said rectangular hanger refractory alternating in said adjacent layers.
