1. A lining for a furnace constructioned in the shape of a truncated cone comprising:
- successive courses of wedge-shaped bricks disposed at a slant with respect to the horizontal and arranged annularly, said bricks having generally planar sides and generally planar top and bottom faces, and a wedge-shape in plan view, wherein said planar top and bottom faces are laid at an angle of slant which is between 5 and 30°
with respect to the horizontal and wherein side faces of abutting bricks are essentially vertical.

Abstract
The lining of conically narrowing or widening walls with brick is facilitated by laying the brick in courses which are closed rings, the bricks subtending an angle of about 5° to 30° with respect to the horizontal.

9. In a vessel having a casing including a vertical wall portion and a truncated conical wall portion slanting with reference to the vertical at an angle α
- , an improved method for instaling a brick lining in the truncated cone walls of said vessel which comprises;
laying at least one course of shaped bricks having generally planar front and back faces and having generally planar side faces and generally planar top and bottom faces and having a wedge shape in a section taken perpendicular to said top and bottom faces and extending from the front face of said brick to the back face of said brick with the top faces of said bricks sloping at an inclination β
with respect to the horizontal, said course being laid to form a ring within the periphery of said vessel adjacent to the base of said truncated cone wall;and thereafter laying a plurality of courses of commercially available wedge shaped bricks having generally planar side faces and generally planar top and bottom faces and having a wedge shape in top plan view, each of said bricks being laid so that its bottom surface rests on the face of the previously laid next adjacent course beneath it, each of said plurality of courses being arranged in a closed ring, and the abutting side faces of the brick in said plurality of courses being vertical, the bricks in any one course of said plurality of courses being laid offset with reference to the bricks of the next adjacent course to provide an overhang at one end of each brick in said course thereby creating a step at said end of said brick in a section taken perpendicular to said top and bottom faces and extending from the front face of said brick to the back face of said brick. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for installing a brick lining in a vessel having truncated cone walls which comprises:
-
laying at least one course of shaped bricks with the bottom faces of the bricks in a horizontal plane and the top faces of the bricks sloping at an inclination between about 5° and
30°
with respect to the horizontal, said course extending within the periphery of said vessel adjacent to the base of said truncated cone wall; andthereafter laying a plurality of courses of commercially available wedge shaped bricks, each of said bricks being layed so that its bottom surface and its top surface is inclined at an angle between 5° and
30°
with respect to the horizontal, each of said courses being arranged in a closed circle and the abutting side faces of said brick are vertical.

18. In a vessel having a casing (2) including a verticall wall portion and a truncated conical wall portion slanting with reference to the vertical at an angle α
- , an improved brick lining for the hot inside face of said truncated conical wall portion comprising;
at least one horizontal course of bricks (4,5) disposed horizontally in a closed ring within said vertical portion of said casing and supporting said lining; a ring of wedge shaped bricks (11) laid on said horizontal course of bricks with the base of each wedge shaped brick being horizontal and the upper surface of each wedge shaped brick sloping at an acute angle β
with respect to the horizontal; anda plurality of successive courses of commercially available wedge shaped bricks laid on said ring of bricks, the bricks of said plurality of courses having generally planar sides and generally planar top and bottom faces and a wedge shape in top plan view;
said bricks being laid in successive courses defining closed rings with the side walls of said bricks being laid vertical and the top and bottom faces of said bricks being laid inclined to the horizontal at said acute angle β
, the bricks of successive courses being laid above the preceding course with an offset which provides an overhang at one end of each brick in said course thereby creating a step at said end of said brick, with reference to the brick in the next adjacent course. - View Dependent Claims (19)
