SOLID THERMAL HEATING BLOCK FROM REFRACTORY PHOSPHATE CONCRETE Russian patent published in 2014 - IPC H05B3/36 

FIELD: heating.

SUBSTANCE: invention relates to the field of resistive heating in industrial resistance furnaces, namely, to solid metal ceramic thermal heating blocks. The solid thermal heating block is made of a non-electroconductive heat-conductive refractory phosphate concrete, in which the heating element is poured, made of a wire heater in the form of a zigzag and belt current leads, besides, the area and the perimeter of the wire section and the area and the perimeter of the current lead section are at the ratio of at least 1:4, axes of symmetry of the heating element match axes of symmetry of the thermal heating block, and areas of connection of the wire heater with current leads in the thermal block are made in the form of cone-shaped grooves.

EFFECT: production of a solid non-electroconductive heating block combining high efficiency, reliability and simplicity of manufacturing.
