Claim:
A cooling plate for a metallurgical furnace comprising: a body with a front face and an opposite rear face, said body having at least one coolant channel therein; a plurality of lamellar ribs on its front face, each rib having a top edge and a bottom edge, and two consecutive ribs being spaced by a groove; inserts fixed in the grooves and projecting from the front face, wherein said inserts have an upper side projecting from the bottom edge of the rib directly above and an upper front edge; wherein the angle (β) between the vertical and a line passing through the upper front edge of the insert and the top edge of the above rib is no less than 45°, whereby said upper side forms a collecting surface taking into account the angle of repose of the burden material so that, in use, furnace burden material may accumulate on said collecting surface up to the top edge of said rib directly above.
