Abstract
A self-positioning refractory structure having a generally cylindrical casing. A plurality of positioning refractories, a plurality of filler refractories and a plurality of wedge refractories are interlocked with respect to each other and positioned to form a structure having a curved cross section within the cylindrical casing. The positioning, filler and wedge refractories are interlocked with respect to each other. The length of each positioning refractory is greater than the length of each filler and wedge refractories thus defining an annular space between the casing wall and the refractories. Each positioning refractory has a cold end in positioning and supporting contact with an inside wall of the casing and a hot end directed toward a center of the self-positioning refractory structure.
Claims33
In a furnace having a generally circular cross section, a self-positioning refractory structure comprising:
- a generally cylindrical casing;
- a plurality of positioning refractories each having straight interlocking means, a plurality of filler refractories each having said straight interlocking means, and a plurality of wedge refractories each having wedge interlocking means, arranged to form a cross-sectionally curved structure within said cylindrical casing;
- said positioning refractories, said filler refractories and said wedge refractories interlocked by said straight interlocking means and said wedge interlocking means forming the self-positioning refractory structure;
- and
- a positioning length of each said positioning refractory being greater than a filler length of each said filler refractory and being greater than a wedge length of each said wedge refractory, each said positioning refractory having a cold end in positioning contact with an inside wall of said casing and a hot end directed toward a center of the self-positioning refractory structure.
In a furnace having a generally circular cross section, a self-positioning refractory structure comprising:
- a generally cylindrical casing;
- a plurality of positioning wedge refractories each having wedge interlocking means and a plurality of filler wedge refractories each having said wedge interlocking means, said positioning wedge refractories and said filler wedge refractories arranged to form a cross-sectionally curved structure within said cylindrical casing;
- said positioning wedge refractories and said filler wedge refractories interlocked by said wedge interlocking means forming the self-positioning refractory structure;
- and
- a positioning length of each said positioning wedge refractory being greater than a filler length of each said filler wedge refractory, each said positioning wedge refractory having a cold end in positioning contact with an inside wall of said casing and a hot end directed toward a center of the self-positioning refractory structure.
