A cooling box for a metallurgical furnace including an elongated hollow body extending from a front end, to an opposite rear end, the rear end being, in use, connected to a wall of the furnace; the body includes an inner chamber having a cooling circuit configured to receive a flow of coolant fluid therein between at least one inlet and at least one outlet; the cooling box further including at least one partition plate fitted in the inner chamber through a form-fit connection to form the cooling circuit.

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.

A cooling plate for use in a blast furnace is described. The cooling plate has a copper body having an inner face containing ribs parallel therebetween, having first extremities and separated by grooves having second extremities. At least one of these grooves containing at least a part of a multilayer protrusion extending between its second extremities and having at least one layer made of a wear resistant material that increases locally the wear resistance of the neighboring ribs.

A cooling panel for a metallurgical furnace includes a body with a front face and an opposite rear face, a top face and an opposite bottom face and two opposite side faces. The body has at least one cooling channel therein, the cooling channel having openings in the rear face; wherein, in use, the front face of the body is turned towards a furnace interior. According to the invention, the cooling panel having at least one cooling pipe arranged in at least one elongate recess formed in the front face, where the cooling pipe has an elongate middle section and at either end thereof, an angled branch, the cooling pipe forming the cooling channel, and where the cooling pipe is arranged in the elongate recess such that the angled branches protrude through the openings in the rear face of the body.

A cooling plate for use in a blast furnace is described. The cooling plate contains a copper body having an inner face containing ribs parallel therebetween, having first extremities opposite therebetween and separated by grooves having second extremities opposite therebetween. At least one of these ribs contains at least one housing located between its first extremities and containing at least one insert made of a wear resistant material that increases locally the wear resistance of this rib.

Supplementary cooling elements in addition to a primary cooling element of a furnace. The supplementary cooling elements, with two or more components, may be inserted from the outside of the furnace into holes that pass through and the primary cooling element such that the cooling elements protrude beyond the inner surface of the primary cooling element. An inner one of the components of the supplementary cooling element may be received by an outer one of the components in a manner that forces the outer component into a thermally conductive pressure connection with the primary cooling element.
