An abrasion-resistant material for the working face of a metallurgical furnace cooling element such as a stave cooler or a tuyere cooler having a body comprised of a first metal. The abrasion-resistant material comprises a macro-composite material including abrasion-resistant particles which are arranged in a substantially repeating, engineered configuration infiltrated with a matrix of a second metal, the particles having a hardness greater than that of the second metal. A cooling element for a metallurgical furnace has a body comprised of the first metal, the body having a facing layer comprising the abrasion-resistant material. A method comprises: positioning the engineered configuration of abrasion-resistant particles in a mold cavity, the engineered configuration located in an area of the mold cavity to define the facing layer; and introducing molten metal into the cavity, the molten metal comprising the first metal of the cooling element body.

An outer lid for an arc furnace includes an outer lid formed from copper or a copper alloy. The outer lid also includes electrode ports, an off-gas chute, and a charge chute. Cooling circuits are present within the outer lid. The bottom surface of the outer lid is exposed to the internal volume of a crucible, and promotes accretion of slag, which can act as a heat barrier.

A metallurgical furnace including a hearth, a sidewall structure, and a surrounding cooling element structure including cooling elements. Each cooling element have a planar back surface. A surrounding binding structure including binding sections surrounds partly the surrounding surface. Adjacent binding sections of the surrounding binding structure are connected by tension assemblies. At least one planar back surface of at least one cooling element is parallel with and is in a horizontal direction of the metallurgical furnace supported by at least one planar surface means of at least one binding section of the surrounding binding structure. Said at least one cooling element of the surrounding cooling element structure is located at least partly between the surrounding surface and said one binding section.

An arc furnace bottom construction for maintaining the outer surface temperature of the bottom construction essentially at least on the lower part of the arc furnace essentially close to the temperature surrounding the arc furnace. The bottom construction contains at least two constructions to be cooled and being positioned to each other in different heights seen from the side view.

A water cooled box to be installed in the side wall of a metal making furnace to hold and protect implements such as a burner, a lance, or a material (i.e., carbon or lime) injection device. The box preferably comprises a copper outer shell and a steel inner shell liner welded together, whereby a chamber is formed through which cooling water passes. The box further comprises an inlet and outlet for the water flow and a plurality of conduit passages between the copper and steel shells for mounting the aforementioned implements. The copper shell has bars or slots for slag retention and the steel shell has means for mounting the box into the furnace wall. The copper shell is formed into a curved U-shape for preventing cracking due to thermal mechanical stress and to raise the natural frequency of the panel to resist vibration which can also cause cracking.

A cooling system for a metallurgical furnace includes a plurality of cooling arrangements having each a set of cooling elements arranged to extract heat from the furnace, the cooling elements having each at least one internal cooling channel for a coolant fluid, where the cooling elements are fluidly connected within each cooling arrangement; at least one discharge piping associated with each cooling arrangement for discharging the coolant fluid towards a main collector, where a flow regulating arrangement is serially mounted with the discharge piping and configured to control a flow rate of the coolant fluid therethrough and hence through the cooling arrangement, where the flow regulating arrangement includes a calibrated orifice defining a default, minimal flow cross section for the coolant fluid and a regulating valve selectively operable to define a variable, additional flow cross-section.

The present invention relates to a fluid cooled housing system for use in metal making furnaces. In particular, the present invention related to a novel and inventive housing and guard member configured to receive and protect an implement, such as a burner or a lance, used in connection with metal making furnaces. A preferred embodiment of the present invention comprises a housing comprising an outer shell and an inner shell that define a fluid chamber, an end cap, a bushing insert, a face plate, a fluid inlet, and a fluid outlet. Both the fluid inlet and the fluid outlet are preferably in fluid communication with both the fluid chamber defined by the shells and a fluid chamber defined by the bushing insert. In alternative preferred embodiments, the housing system further comprises a guard member that preferably envelopes and further protects the fluid cooled housing.

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.

Embodiments of the present disclosure generally relate to a reflector plate assembly. The reflector plate assembly includes a reflector plate and a baffle. The reflector plate includes a gas conduit, a plurality of gas passages, a plurality of lift pin holes, and a gas inlet. The gas conduit includes a first opening on a front side of the reflector plate and a second opening on a backside of the reflector plate adjacent to the gas conduit. The baffle is attached at a first end to a support base of an edge ring. The baffle is attached at a second end to the backside of the reflector plate. The baffle forms an opening in the backside of the reflector plate to the gas conduit.

The present disclosure relates in general to a furnace apparatus and in particular to a system including a method and apparatus for detecting leaks in fluid-cooled panels, burner housings, and/or any fluid cooled component for industrial furnaces such as metal smelting furnaces, blast furnaces, electric arc furnaces (EAFs) or the like.
