The invention relates to an arrangement for mounting electric heating elements in a furnace in which objects are intended to be heated, wherein the furnace wall includes a furnace insulation ( 4 ) comprised of high grade brick, and wherein the heating zones ( 6 ) of respective electric heating elements ( 2 ) are placed vertically and parallel with the inner surface of the furnace wall in operation. The invention is characterized in that the electric leads or conductors ( 7, 8 ) of each element ( 2 ) are mounted in a cassette ( 9 ) and extend in channels ( 10, 11 ) therein; in that the heating zone ( 6 ) of the heating element projects outwards and defines an angle with the longitudinal axis of the cassette ( 9 ); in that the furnace insulation ( 4 ) includes for each cassette a hole ( 12 ) which is larger at its outer end than at its inner end, therewith enabling the cassette ( 9 ) to be rotated in a vertical plane as the heating zone ( 6 ) of the element ( 2 ) is inserted through the hole ( 12 ) and into said operating position parallel with the furnace wall; and in that a wedge-like body ( 13 ) is provided, whose shape corresponds to the shape of the empty space created by the shape of the hole ( 12 ) and located between the hole ( 12 ) and the cassette ( 9 ) when the cassette is placed in operating position in the hole, said body ( 13 ) being placed in said empty space during operation. |
