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.

A 180-degree pipe elbow having one end extending beyond the other end and method of joining a 180-degree pipe elbow to lengths of cooling pipe to form a cooling panel for use in a furnace, boiler or other industrial heating apparatus that benefits from assistance of a cooling panel. Having one end of the elbow extend beyond the other end of the elbow enables the one end to be joined to a length of pipe by welding whereby the joining may be by automatic welding which will reduce manufacturing costs and ensure a quality weld.

A control system for a vacuum arc remelting (VAR) process for a metal includes a direct current (DC) power source, a ram drive, voltage drip short sensor, and a controller, which includes a processor. The drip short sensor may be configured to measure a drip short frequency of the electric arc over a period of time. The controller is configured to determine a real time arc gap length between the electrode tip and the melt pool based on a correlation between the drip short frequency and arc gap length. The controller is further configured to control power input to the electrode by the DC power supply by determining an input power level to input to the electrode based on the real time arc gap length, the input power level configured to generate a desired arc gap length, by the DC power supply, at the input power level.

An apparatus (1) for adjusting the heat exchange, comprising shielding means (10) intended to be arranged facing at least one portion of a heat exchanger (2), and provided with at least one screen (11) movable between a position of maximum covering (C) of the heat exchanger (2) and an exposure position, in which the heat exchanger (2) is left at least partially uncovered by the screen (11).

A batch annealing furnace includes a coil support base on which an end face of a coil is mounted and that supports the coil with an axis of the coil being upright, an inner cover that covers an entire body of the coil mounted on the coil support base, and a cooling pipe that extends downward from the upper part of the inner cover to a cavity of the inner peripheral part of the coil mounted on the coil support base and cools the coil from the inner surface side by passing a coolant through the inside of the cooling pipe.

A cooling element for a furnace includes a first side configured to be directed towards the inside of the furnace, a second side opposite to the first side and configured to be directed away from the inside of the furnace, and a cooling fluid channel system for cooling fluid circulation. The cooling element further includes a monitoring channel system including at least one monitoring channel for pressure medium. At least a portion of the monitoring channel extends in a portion of the cooling element provided between the first side and a plane defined by the points of the cooling fluid channel system closest to the first side.

The present invention is applied in the field of heat exchange and temperature regulation and, more specifically, relates to an outer cooling assembly for structures with inner refractory lining, the outer cooling assembly comprising: a distributor arranged on the outer side and around an upper section of a structure with inner refractory lining; and a collector arranged below the distributor and on the outer side and around a lower section of a structure with inner refractory lining; wherein the distributor comprises a fixing plate and cooling fluid injection members arranged on the outer side and around the fixing plate and configured to eject cooling fluid onto the outer surface of the structure.

A melting hearth includes high temperature walls, a melting cavity having a specific topography, and conformal fluid cooling passages configured to provide a flow path for a cooling fluid that is substantially parallel to the topography of the melting cavity. In addition, the topography of the melting cavity mirrors a heat signature of a heat source used to melt a feed material in the melting hearth into a molten metal. A cold hearth melting system includes the melting hearth, a magnetic stirring system, the heat source having the heat signature, a tilting mechanism for tilting the melting hearth to a desired tilt angle, and a fluid cooling system having a fluid source in flow communication with the conformal fluid cooling passages. A process for producing high temperature metal alloys uses the cold hearth melting system and an algorithm for controlling the pouring of the molten metal from the melting hearth.

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.

A cooling assembly for cooling exhaust gases emitted from a steel-making furnace includes a body having a cross-sectional shape with a thickness defined between an outer surface and an inner surface thereof. The body includes a first mounting end having a first length and a second mounting end having a second length, the second length being different from the first length. The body is arcuately-shaped with a concave inner surface and convex outer surface, and the second mounting end is spaced from the first mounting end. A fluid conduit is defined between the inner surface and the surface for a cooling fluid to flow therethrough.
