GRATE OF GRATE COOLER OF SHEARING TYPE Russian patent published in 2013 - IPC F27B21/08 F23H17/12 

FIELD: metallurgy.

SUBSTANCE: grate of a grate cooler of shearing type includes a horizontal base and a working plate of straight-line shape with through passes for cooling air, which is inclined to it; at that, in the working plate there are cavities that in a vertical longitudinal grate plate section have the shape of triangles adjacent to each other so that alternating cavities and projections are formed. In all the cavities of the grate working plate there is heat insulating and wear resistant lining. Cavities in the grate working plate are made in all sections between through passes for cooling air. Cavities in the grate working plate are made in sections above stiffeners.

EFFECT: invention has simple design and provides reduction of metal consumption and cost of the grate, reduction of its operating temperature, reduction of abrasive and corrosive wear, and increasing strength and operating life of the grate.
