BLOCK STRUCTURE, CONTAINER AND METHOD FOR CONSTRUCTING BLOCK STRUCTURE
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.
Wear resistant composite material, its application in cooling elements for a metallurgical furnace, and method of manufacturing same
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.

Coke oven corbel structures and methods of forming the same
Coke oven corbel structures include an assembly of multiple stacked tiers of refractory blocks defining a plurality of substantially vertically oriented central flues and a plurality of diagonally oriented lateral flues. At least one tier of refractory blocks in the assembly includes a plurality of tongue-and-groove interconnected refractory blocks. This plurality of interconnected refractory blocks of the at least one tier comprise mutually substantially orthogonal faces defining an edge and respectively including an elongate tongue protruding outwardly therefrom and an elongate groove recessed therein. The elongate tongue and groove include respective adjacent ends which co-terminate with one another at the edge defined by the mutually orthogonal faces of the refractory blocks.
Integral self-supporting composite refractory wall modules for refractory structures and methods of forming refractory structure walls of the same
Refractory modules are provided by multiple preformed refractory blocks bonded to one another by a bonding agent to form an integral self-supporting structure having a tooth and channel arrangement for interlocking assembly with a similar adjacently positioned refractory module.
STAVE WITH EXTERNAL MANIFOLD
A stave comprising an outer housing, an inner pipe circuit comprising individual pipes housed within the outer housing, wherein the individual pipes each has an inlet end and an outlet end and wherein each pipe may or may not be mechanically connected to another pipe, and a manifold, integral with or disposed on or in the housing; wherein the inlet and/or outlet ends of each individual pipe is disposed in or housed by the manifold.

Fired precast block
A fired precast block prevents itself from dropping off early due to corrosion and increases service life of a blast furnace runner, etc. when used in a very vulnerable portion of the blast furnace runner, etc., and can be produced at low costs. The fired precast block has an upper surface to contact molten metal or slag, a lower surface opposing the upper surface, and a plurality of side surface. The fired precast block is used by being embedded in a castable in such a manner that the upper surface is exposed from the castable and the lower surface and the plurality of side surfaces contact the castable. Each side surface of at least one opposing pair of side surfaces includes a planar portion and an uneven portion. The uneven portion has at least one groove-shaped concave portion.
