FIELD: metallurgy.SUBSTANCE: cooling plate includes a cooled plate provided with longitudinal through channels and transverse non-through channels connected to them for circulation of cooling medium, which form cooling circuits, and holes with outlets for supply and removal of cooling medium. The cooled plate is provided with additional longitudinal non-through channels that are made on one axis and connected with transverse non-through channels to longitudinal through channels. Holes for supply and removal of cooling medium are made in end parts of additional longitudinal non-through channels with their being located in the central part of the cooled plate.EFFECT: improving reliability, resistance, durability of operation and reducing manufacturing costs of a cooling plate of a blast furnace.6 cl, 2 dwg |
