A cooling plate for a metallurgical furnace comprising a body () with a front face () and an opposite rear face (), the body having at least one coolant channel () therein; the front face () being turned towards the furnace interior and preferably comprises alternating ribs () and grooves (). The cooling plate includes wear detection means comprising: a plurality of closed pressure chambers () distributed at different locations in said body, said pressure chambers being positioned at predetermined depths below the front face () of said body; and a pressure sensor () associated with each pressure chamber () 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.

Blast furnace cooling plate with integrated wear detection system

A stave cooler for a metallurgical furnace includes a panel-like body having a front face for facing the interior of the metallurgical furnace, an opposite rear face, an upper face, an opposite lower face, and two side faces. At least one internal coolant passage is arranged within the panel-like body. The panel-like body is provided with a ledge on its front face extending between the side faces for being arranged in a horizontal plane. At least one protection element is provided for covering at least part of an upper face of the ledge. The protection element includes a first lateral portion, a second lateral portion, and a central portion. The lateral portions each include a widened front section and a narrow connection section. The panel-like body is provided with at least one through hole arranged for passing each of the lateral portions and the central portion of therethrough in turn.

Stave cooler for a metallurgical furnace and method for protecting a stave cooler

The present invention proposes a gap-filler insert () for use with cooling plates () for a metallurgical furnace, the cooling plates () having a front face () directed towards the interior of the furnace, an opposite rear face () directed towards a furnace wall () of the furnace and four edge faces (). In accordance with an aspect of the present invention, the gap-filler insert () comprises a metal front plate () with a front side () facing the interior of the furnace and anchoring means () for mounting the front plate () between two neighboring cooling plates () in such a way that the front plate () extends between the edge faces () of both cooling plates (), and that the front side () of the front plate () is flush with the front faces () of both cooling plates ().

Cooling plate arrangement and method for installing cooling plates in a metallurgical furnace

A cooling plate () for a metallurgical furnace in accordance with the present invention has a panel-like body () with a front face () and an opposite rear face (), an upper edge () and an opposite lower edge (), and a first side edge () and an opposite second side edge (). The front face () is provided with grooves () extending between the first and second edges (), the grooves () forming lamellar ribs () on the front face (), each rib () having a crest () and adjoining sidewalls (), a base () being arranged in the groove () between two neighboring ribs (). In accordance with an important aspect of the present invention, at least one of the grooves () is provided with a metal insert () arranged against at least one of the sidewalls ().

Cooling plate for a metallurgical furnace

A method for protecting a tuyere assembly and a refractory lining of a furnace, and in particular a blast furnace, against damage caused by expansion of the refractory lining. This method includes providing a clearance between the tuyere assembly and a refractory lining portion below the tuyere assembly and monitoring this clearance by means of a displacement sensor.
