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.

High heat flux furnace cooler comprise CuNi pipe coils cast inside pours of high purity (99%-Wt) copper. The depth of front copper cover over the pipe coils in the hot face to manufacture into the casting is derived from a projection of the thermal and stress conditions existing at the cooler's end-of-campaign-life. CFD and/or FEA analyses and modeling is used for a trial-and-error zeroing in of the optimum geometries to employ in the original casting of CuNi pipe coils in high purity copper casting. Individual pipe coil positions to cast inside a copper casting mold are secured with devices that will not melt, cause thermal shear stresses, or be the source of contaminations or copper defects. Pipe bonding to the casting results because the differential coefficient of expansions of the pipes' and the casting's copper alloys involved do not exceed the yield strength of the casting copper during operational thermal cycling.

A metallurgical furnace cooling plate includes a cooling plate body with front and rear faces and at least one coolant channel inside the body, which communicates with a rear opening on the rear face; and a connection pipe connected to the body so that a pipe channel of the connection pipe communicates with the coolant channel, the connection pipe adapted for carrying coolant fluid to or from the channel.

The body includes a receiving bore extending in a bore direction from the rear opening into the coolant channel, the channel being spaced in the bore direction from the rear face by a cover thickness of a cover portion and extends in the bore direction over a width. A connection pipe end portion extends into the receiving bore beyond the cover thickness and is form-fittingly received in the receiving bore along at least a portion of a width of the channel.
