Abstract
An assemblage of electrode blocks peripherally supported on the bottom wall of an electric glass-melting furnace, having apertures for positioning electrodes therethrough and having horizontal grooves cut between adjacent vertical sides with a key positioned in the groove to secure the blocks, and on another of the vertical sides, having a ledge parallel and located between the top and bottom of the electrode blocks, such that a plurality of paving blocks can be positioned to retain the electrode blocks against the bottom wall of the furnace.
Claims5
An electric glass-melting furnace having a bottom wall comprising:
- a. an assemblage of electrode blocks peripherally supported on the bottom wall of said furnace through which electrodes are inserted;
- b. a first electrode block having an aperture for positioning an electrode therethrough and having a top and four sides perpendicular to said top, wherein a first and second side being adjacent one another, have a groove cut therethrough parallel to the top;
- c. a second electrode block having an aperture for positioning an electrode therethrough and having a top, bottom, and a first side perpendicular to said top, said first side having a groove cut therethrough in mating relation with said first side of said first block, and a second side, adjacent the first side, having a ledge parallel to and located between the top and bottom of said second block;
- d. a third electrode block having an aperture for positioning an electrode therethrough and having a top, bottom, and a first side perpendicular to said top, said first side having a groove cut therethrough in mating relation with said second side of said first block, and a second side adjacent to the first side having a ledge parallel to and located between the top and bottom of said third block;
- e. a first key positioned in the groove formed between the first sides of the first and second blocks, and a second key positioned in the groove formed between the first side of the third block and the second side of the first block, thereby enjoining said blocks;
- and
- f. a plurality of paving blocks positioned on said ledges to retain said electrode blocks against the bottom wall of said furnace.
A method of retaining electrode blocks against the bottom wall of an electric glass-melting furnace comprising:
- inserting a key in a groove cut in each of the adjacent vertical walls of at least two of the electrode blocks;
- and positioning paving blocks on ledges carved into opposite and adjacent walls of the keyed electrode blocks.
