Claim:
A liquid-cooled permanent mold for the continuous casting of metals, comprising: mold plates made of copper or a copper alloy, which are connected respectively to an adapter plate or a water-cooling tank by clamping bolts, the clamping bolts being fastened to plateau pedestals that protrude in an insular fashion from the coolant side, which a least partially extend into a coolant gap formed between the mold plate and the adapter plate or the cooling-water tank, wherein the coolant side has cooling ribs that extend into the coolant gap and are situated from place to place between two adjacent plateau pedestals, wherein the cooling ribs are dimensioned in such away that the flow cross section of the coolant gap in areas provided with cooling ribs is smaller than the flow cross section in areas without cooling ribs sufficient to assure an increase in the speed of coolant flowing through the cross section in areas with the cooling ribs relative to the cross section with out cooling ribs.
