The invention relates to a metal element (12) for anchoring an anti-erosion coating that is intended to be fastened alone in an isolated manner to a metal wall or assembled with other identical anchoring elements. The anchoring element (12) has an edge (12a) for fastening to said metal wall and an anchoring body firmly attached to the fastening edge (12a) and having an upper edge (12b) that is away from the fastening edge and intended to be covered by a composite material of concrete type. A section of this upper edge (12b), which is not intended to be juxtaposed and assembled with an upper edge of an identical anchoring element, is provided with a delimiting tab (16) in order to delimit a height of composite material that must cover the upper edge (12b) of said anchoring element, said delimiting tab (16) having a delimiting edge (18) that is a predetermined distance away from a plane defined by the upper edge (12b) of the anchoring element.

A modular structure wall of a high-temperature furnace, which greatly increases the radiation coefficient of the inner wall, enhances heat transfer efficiency, saves energy, reduces emissions, slows aging, and prolongs the furnace wall service life. The modular wall comprises preset furnace wall main trusses and a furnace roof truss. Connecting I-beams are respectively fixed on the bottom surface of the roof truss. Top clamping structures of hoisting outer screws are hooked with the bottoms of the I-beams. Upper surfaces of ceramic fiber cotton modules are uniformly distributed with upwardly convex hoisting outer screws. The ceramic fiber cotton modules are installed on the lower surface of the roof truss through the outer screws. A ceramic fiber cotton felt is laid in the gap between these modules and the lower I-beam surfaces, and a furnace wall inner protective lining is installed on the lower surfaces of the ceramic fiber cotton modules.

A refractory insert is provided, including a main body part having a first surface defining a first sidewall, an opposed second surface defining a second sidewall, and an outer peripheral surface separating the first and second surfaces, and a mechanical mating member provided on at least a portion of the outer peripheral surface thereof. The mechanical mating member includes a retention mechanism for controlling and retaining a position of a corresponding mating member in connection therewith.

The invention relates to a refractory anchor comprising an elongated mounting pin having a first end and a second end opposite to the first end seen in the longitudinal direction of the elongated mounting pin, wherein the first end of the elongated mounting pin is weldable to an object, the refractory anchor further comprises two anchor fins of which each has a first anchor fin section having a first side and an opposing second side located at a distance of the elongated mounting pin with respect to the first side, wherein the first side is connected to the elongated mounting pin.

The invention relates to a refractory anchor comprising an elongated mounting pin having a first end and a second end opposite to the first end seen in the longitudinal direction of the elongated mounting pin, wherein the first end is weldable to an object, the refractory anchor further comprises at least one anchor fin having a first side at least partially connected to the elongated mounting pin. The invention further relates to an assembly comprising an object and a refractory anchor welded to the object, and to a method for manufacturing the assembly.

A shielding module for a high-temperature furnace has a packet of interconnected shielding plates. The packet of interconnected shielding plates is mounted to a common base body. The base body has fixing points for fixing to base bodies of other shielding modules of the same kind.

An anchoring assembly for a refractory material for a protected surface includes a V-anchor and an eye-mount. The eye-mount mounts to the protected surface, the V-anchor mounts to the eye-mount, and the refractory material is applied and anchored to the V-anchor. The eye-mount includes a through-hole, and a saddle channel in communication with the through-hole, that are configured to receive and seat the V-anchor through the through-hole and into the saddle channel with a snap-fit connection. In some embodiments, the V-anchor is seated with a tight snap-fit connection that holds the V-anchor in an upright use position, and in other embodiments the V-anchor includes a spacer that provides the tight snap-fit connection and that is removable in-situ after application of the refractory material to convert the tight snap-fit connection to a floating snap-fit connection.

A modular dome structure (5) for a masonry oven, which includes a plurality of interlocking wall modules (60) abutting one another to form a wall of the dome and a base (7) upon which the wall modules are mounted. Each wall module (60) is formed of a plurality of blocks (63) hingedly interconnected together and shaped so as to form an arch segment of the dome wall when facing surfaces of adjacent blocks (63) of the wall module (60) abut and interlock with one another.

Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body has the shape of two end-to-end Y's forming a central segment, two branch segments extending from each end of the central segment, and an extension segment extending from each of the four branch segments, to collectively form four unenclosed cell openings that are each semi-hexagonal in shape. Some embodiments include four reinforcement segments with each one extending into a respective cell opening, four voids with each one extending through respective adjacent branch and extension segments, an underbody gap formed under the central segment for refractory interlinking between cell openings, and/or a single stud-welding stud for the mounting feature. Refractory anchoring systems and methods include an array of the refractory anchoring devices arranged and mounted so that the unenclosed semi-hexagonal cell openings of adjacent anchoring devices cooperatively form substantially hexagonal cells.

A furnace stave comprising a plurality of internal channels or conduits for circulating cooling fluid through the stave; an inlet and an outlet channel associated with each internal channel or conduit; wherein one of the internal channels or conduits is disposed in a protrusion from the stave.
