RESISTANCE BOX FURNACE FROM PHOSPHATE BLOCKS Russian patent published in 2013 - IPC F27B3/14 F27B3/16 F27D1/06 

FIELD: metallurgy.

SUBSTANCE: proposed furnace comprises lining, interconnected on-piece heat-insulating blocks and heat blocks, and furnace outer metallic shell. Furnace roof is composed of one row of central one-piece heat-insulating blocks, two rows of bearing one-piece heat-insulating blocks while furnace hearth is composed of two rows of one-piece heat-insulating blocks and one row of heat blocks. All parts of lining are composed of one-piece blocks from high-strength refractory nonconducting phosphate concretes used as structural load bearing elements.

EFFECT: high-strength refractory lining with low consumption of electric power, decreased overall dimensions.
