Refractory lining for a furnace

Claim 2

A furnace wall comprising a sheet mantle, a casting mass and means for removing said casting mass from said sheet mantle comprising precast refractory anchoring elements defining a conical or pyramid shape and a cross-section which increases in a direction away from the sheet mantle, said casting mass and said precast refractory anchoring elements cast into a monolithic refractory mass, said precast refractory anchoring elements including bolts extending therefrom and anchoring bars cast into said precast refractory anchoring elements, said bolts extended through holes in said mantle and secured at the exterior of said mantle by removable securing means, said sheet mantle supporting said casting mass and said precast refractory anchoring elements, said monolithic refractory mass anchored to said sheet mantle by said anchoring bars.

Claim 3

A furnace wall defined by a sheet mantle, a casting mass and means for removing said casting mass from said sheet mantle comprising precast refractory anchoring elements, said casting mass and said precast refractory anchoring elements cast into a monolithic refractory mass, a plurality of said precast refractory anchoring elements extending above the casting mass and defining a substantially parallelpiped so as to provide a lifter lining, said precast refractory anchoring elements including bolts extending therefrom and anchoring bars cast into said precast refractory anchoring elements, said bolts extended through holes in said mantle and secured at the exterior of said mantle by removable securing means, said sheet mantle supporting said casting mass and said precast refractory anchoring elements, said monolithic refractory mass anchored to said mantle by said anchoring bars.

Claim 4

A furnace wall defined by a sheet mantle, a casting mass and means for removing said casting mass from said sheet mantle comprising precast refractory anchoring elements, said casting mass and said precast refractory anchoring elements cast into a monolithic refractory mass, a plurality of said precast refractory anchoring elements extending above the casting mass and defining a substantially parallelpiped so as to provide a lifter lining, said precast refractory anchoring elements including bolts extending therefrom and anchoring bars cast into said precast refractory anchoring elements, said bolts extended through holes in said mantle and secured at the exterior of said mantle by removable securing means, said sheet mantle supporting said casting mass and said precast refractory anchoring elements, said monolithic refractory mass anchored to said mantle by said anchoring bars.

Claim 5

A liner according to claim 1, wherein each bolt has a portion internal of said anchoring element, said anchoring bars affixed to and extending transversely of said internal portion.

Claim 6

A lining according to claim 3, wherein said sheet mantle is cylindrical, said cross-section increases in a radially inward direction, and said bolts extend radially outwardly from said anchoring elements through said holes.

Claim 7

A lining according to claim 2, wherein each bolt has a portion internal of said anchoring element, said anchoring bars affixed to and extending transversely of said internal portion.

Claim 8

A lining according to claim 5, wherein said sheet mantle is cylindrical, said cross-section increases in a radially inward direction, and said bolts extend radially outwardly from said anchoring elements through said holes.
