material hopper, rod furnace and blast furnace loading device

摘要

It is a material hopper, in particular for a blast furnace, which comprises a hollow enclosing enclosure (12) for storing material, the enclosure comprising an upper enclosure portion (20) with an inlet portion (). and an asymmetric funnel-shaped lower housing portion (26) with an outlet portion (28). a wear plate arrangement (42) covers at least part of an inner wall (14) of the lower housing portion (26), wherein the wear plate arrangement comprises a plurality of wear plates (44) disposed adjacent a to the other in a plurality of rows stacked along the inner wall. The wear plates (44) are arranged in rows following parallel assembly lines (48) which are defined by intersecting the lower housing portion (26) with planes perpendicular to the geometry axis (v) of a virtual right circular cone (50). ) which substantially corresponds to the shape of the funnel-shaped lower shell portion (26).
