Blast furnace cooling plate with integrated wear detection system

A cooling plate for a metallurgical furnace comprising a body (12) with a front face (18) and an opposite rear face (20), the body having at least one coolant channel (14) therein; the front face (18) being turned towards the furnace interior and preferably comprises alternating ribs (22) and grooves (24). The cooling plate includes wear detection means comprising: a plurality of closed pressure chambers (26, 28) distributed at different locations in said body, said pressure chambers being positioned at predetermined depths below the front face (18) of said body; and a pressure sensor (30) associated with each pressure chamber (26, 28) in order to detect a deviation from a reference pressure inside said pressure chamber when the latter becomes open due to wear out of said body. 种用于冶金炉的冷却片，包括具有正面(18)和相反的背面(20)的主体(12)，在所述主体中具有至少个冷却剂通道(14)；所述正面(18)被转向为朝向炉内部并且优选地包括交替的肋(22)和凹槽(24)。冷却片包括磨损检测装置，该磨损检测装置包括：分布在所述主体中的不同位置处的多个闭合压力腔，所述压力腔被定位在所述主体的正面之下的预定深度处；以及压力传感器(30)，其与每个压力腔(26、28)相关联，以便在压力腔因所述主体的磨损而变为打开时检测相对于所述压力腔内的参考压
