CHAMBER ELECTRIC RESISTANCE FURNACE Russian patent published in 2006 - IPC C03B5/27 F27B3/04 

FIELD: metallurgical industry; building industry.

SUBSTANCE: the invention is pertaining to the field of metallurgical industry and building industry, in particular, to the chamber electric resistance furnace. The chamber electric resistance furnace for manufacture of the pyroceramic products contains the working chamber with the vertical faces, the rod-like heaters fixed in the annular type anode- cathode holders, which are in the contact with the main current lead, and also one or a set of the vertical casting molds, each of which is arranged in the working chamber. The furnace is supplied with the additional annular anode-cathode holders, in which there are the tubular vertical casting molds arranged in height of the working chamber and fixed, and with the additional current lead, which is in the contact with the additional annular anode-cathode holders. The working chamber has the central pole mounted along its vertical axis and fixed in the annular anode-cathode holders, which are in contact with the main current lead. The refractory brickwork of the working chamber contains the air-ventilation chamber serving for refrigeration of the working chamber and is supplied with the mounted outside the furnace ventilators and with arranged in blast-furnace brickwork of an air-ventilation chamber the entrance door and the air ventilation channels. At the usage of the invention it ensures the optimum mode of manufacture of the large-size pyroceramic hardware products.

EFFECT: the invention ensures the optimum mode of production of the large-size pyroceramic hardware products.
