<p>A method for manufacturing a cooling plate (10) for a metallurgical furnace comprising the steps of providing a slab (11) of metallic material, the slab (11) having a front face (14), an opposite rear face (16) and four side edges; and providing the slab (11) with at least one cooling channel (30) by drilling at least one blind borehole (40) into the slab (11), wherein the blind borehole (40) is drilled from a first edge (22) towards an opposite second edge (24). In accordance with an important aspect of the present invention, the method comprises the further steps of deforming the slab (11) in such a way that a first edge region (46) of the slab (11) is at least partially bent towards the rear face (16) of the slab (11); and machining excess material from the front and rear faces (14, 16) of the slab (11) to produce a cooling plate (10) having a panel-like body (12) wherein an opening to the cooling channel (30) is located in the rear face (16).</p> |
