All of a cast-iron or cast-copper stave cooler's weight is supported inside a furnace containment shell by a single gas-tight steel collar on its backside face. All the coolant piping in each cooler has every external fluid connection collected and routed together through the one steel collar. A wear protection barrier is disposed on the hot face. At least one of horizontal rows of ribs and channels retain metal inserts or refractory bricks, or pockets that assist in the retention of castable cement and/or accretions frozen in place from a melt, or an application of an area of hardfacing that is welded on in bead, crosshatch, or weave pattern.

A stave cooler for a furnace that always includes a liquid coolant piping cast inside. A stave cooler body includes a hot face and a backside and a liquid coolant piping cast inside between the hot face and the backside. A single steel collar on the backside of each stave is engineered to support the entire weight of the stave cooler. Any and every external connection of the liquid coolant piping are collected and routed together through the single steel collar. These stave coolers are limited to those mountable only from the inside of steel containment shells provided with a matching penetration. The single steel collar and a cover plate accommodate and provide a gas-tight seal by a continuous welding of the single steel collar to each steel containment shell.

A shaft furnace, in particular a blast furnace, includes a metal jacket defining the furnace outer wall and a protective layer protecting the inner surface of the outer wall. At least one condition monitoring probe is arranged inside within the protective layer to monitor the latter. The condition monitoring probe is connected to a wireless module arranged outside the outer wall to transmit condition monitoring data. The wireless module is located inside a casing mounted to the outer surface of the metal jacket. The condition monitoring probe includes one or more conductive loops positioned at predetermined depths below the front face of the cooling plate body, or of the refractory lining, so that wear of the body, resp. refractory, can be detected by a change of an electrical characteristic of the loop(s) due to abrasion.

A device for mounting and/or dismantling staves on/from an inner wall of a shaft furnace, the device including a circular monorail for supporting at least one stave positioning hoist, where the monorail is divided into at least four separate arc portions, where each arc portion is connected to a neighboring arc portion by means of a rotatable connection, the arc portions are moveable between an unfolded position, in which the arc portions form a circular monorail, and a folded position, in which the overall size of the monorail is, in one direction, reduced.

A device for cooling the supporting trunnions of a distribution spout of a charging installation of a shaft furnace, wherein the spout is mounted pivotably about a horizontal axis on a shell coaxial with the furnace and the spout is attached rotatably to the trunnions driven in rotation by a drive component. The trunnions are directly attached for rotation by their ends to output shafts of reduction gears and include internal cooling channels. The cooling device includes feed and return ducts for the cooling water circulating in the internal channels. The feed and return ducts are connected to the trunnions by connectors fixed to the cylindrical surface of the trunnions. The feed and return ducts are arranged to permit rotational displacement of the connectors about the pivot axis of the spout during pivoting of the spout, in particular by passing through oblong slots extending circumferentially in the wall of bearings supporting the driving reduction gears.

Provided is a block structure that may uniformly distribute a force applied by a charging material, a container including the block structure, and a construction method applied thereto. The block structure includes: a main body having one face extending in one direction and another direction perpendicular to one direction; and a plurality of blocks coupled to one face of the main body and being in contact with each other. Further, an engaged groove and an engaging protrusion are respectively formed on both opposed faces of each of the blocks, the opposed faces facing away each other in at least one of one direction or another direction.
