It is intended to provide a method for forming a brick lining to construct a sidewall of a kiln/furnace, while improving efficiency of brick lining forming work without causing any increase in manufacturing cost of bricks to be used. The brick lining forming method comprises stacking a plurality of tiers of bricks, respectively, on a plurality of tier regions of an inner surface of a hollow approximately cylindrical-shaped peripheral portion of a kiln/furnace to construct a side wall of the kiln/furnace, wherein two or more of the plurality of tier regions are different in terms of pre-lining radius, wherein only bricks identical in terms of taper angle and height dimension are used, except for an adjustment brick, in each of the two or more tier regions different in terms of the pre-lining radius, wherein bricks identical in terms of the taper angle, the height dimension and length dimension, and different in terms of back face width, are used in at least a part of each of the two or more tier regions.

An installation method of a refractory fiber integral module, includes: carrying out construction pretreatment, then welding an anchoring part to a furnace wall, and then laying a tiled layer along the furnace wall; then fixing the refractory fiber integral module neatly on a hot surface of the tiled layer by the anchoring part to form a refractory fiber prefabricated layer, and filling reserved gaps between the refractory fiber integral modules with compensation strips; finally checking the refractory fiber prefabricated layer, and repairing gaps whose width is greater than a preset width.

A refractory impact pad includes a bottom wall, a side wall, and a top wall. The bottom wall has a basal surface. The side wall extends from a periphery of the bottom wall. The side wall has an inner surface that at least partially encircles the basal surface of the bottom wall. The inner surface of the side wall has inner surface teeth distributed thereon and protruding inwardly from the inner surface of the side wall. The top wall is joined to the side wall and separated from the bottom wall by the side wall. The top wall extends over the inner surface of the side wall and the inner surface teeth of the side wall. The top wall has a bottom surface facing the bottom wall. The bottom surface of the top wall has bottom surface teeth distributed thereon and protruding toward the bottom wall.

Coke oven corbel structures are provided with a multiple number of stacked refractory slabs defining a corresponding multiple number of tiers of the corbel structure, The multiple number of stacked refractory slabs define a pair of substantially vertically oriented central fuel gas passageways and pairs of combustion air passageways laterally of a respective one of the central fuel gas passageways. A plurality of vertically stacked fuel gas blocks each defining a central fuel gas conduit may be positioned within each of the central fuel gas passageways.

A corner block for a glass furnace tank. The corner block has an outer surface including: upper and lower surfaces delimiting the length of the corner block, right and left surfaces to be in contact with corresponding surfaces of adjacent blocks, a hot face to be in contact with the environment inside the tank, and a cold face, opposite the hot face. A main portion of the corner block extends, over more than 80% of the length of the corner block, between two limiting upper and lower transverse planes. The hot face is edge-free. An edge is a line along which the hot face has a break in slope greater than 25°. The hot face has a profile that is convex in any transverse sectional plane in the main portion.

A heat insulating protective member including an inorganic fiber formed body having a hollow cylindrical shape or a split hollow cylindrical shape, wherein the inorganic fiber formed body has an inner circumferential surface (c) facing a hollow and an outer circumferential surface (a) constituting an outer circumference, and the bulk density of the inorganic fiber formed body increases toward the outer circumferential surface (a).

Disclosed is a method of manufacturing a heat insulation wall body, by which the heat insulation wall body can be manufactured economically. The method is a manufacturing method of a heat insulation wall body having a groove portion formed by a first side wall, a second side wall and a groove bottom. The method includes dispersing and mixing a heat insulating material in an aqueous medium to prepare a slurried heat insulating material, bringing a molding die having a vent and a surface corresponding to a shape of the groove portion, into the obtained slurried heat insulating material, and dehydrating the slurried heat insulating material via the vent, and releasing the molding die from the heat insulating material to prepare the heat insulation wall body in which a depth of the groove portion is fixed, and a width of the groove bottom is varied in a longitudinal direction of the groove portion.
