Impact pot with vertical and horizontal barriers

Refractory impact pot (1) comprising a bottom (10) having an impact surface (10s), a wall (12) having an inner surface (12i), the wall (12) extending from said bottom (10) upwardly to an upper end (14) of the impact pot (11), the inner surface (12i) of the wall (12) and the impact surface (10s) defining an inner space (16), wherein a plurality of horizontal barriers (2) is provided, wherein the horizontal barriers (2) have a horizontal dimension that is at least 10% larger than their vertical dimension, the plurality of horizontal barriers (2) projecting in a protrusion direction (p) from the inner surface (12i) of the wall (12) into the inner space (16), characterized, in that a plurality of vertical barriers (3) projecting in protrusion direction (p) from the inner surface (12i) of the wall (12) into the inner space (16) is provided, wherein the vertical barriers (3) have a vertical dimension that is at least 10% larger than their horizontal dimension, and wherein the plurality of vertical barriers (3) is arranged below the plurality of horizontal barriers (2), and wherein the plurality of vertical barriers (3) is arranged at least partially within horizontal gaps (G2) between horizontal barriers (2) which are adjacent to the respective vertical barrier (3).
