Abstract: Flame spraying repair equipment for repairing the wall brick of a carbonization chamber of a coke oven by spraying, comprising a first burner and a second burner each having a powder injection nozzle for injecting spray powder, and a plurality of flamethrower nozzles arranged around the powder nozzle. First intersections where the throwing axes of flame of respective flamethrower nozzles of the first burner intersect each other are located on the powder injection line of the powder injection nozzle of the first burner. Second intersections where the throwing axes of flame of respective flamethrower nozzles of the second burner intersect each other are located on the power injection line of the powder injection nozzle of the second burner. The distance from the powder injection nozzle of the first burner to the first interconnection is longer than the distance from the powder injection nozzle of the second burner to the second interconnection.

Abstract: PROBLEM TO BE SOLVED: To prevent a decrease in an attachment rate caused by the scattering of a fire-resistant material when the fire-resistant material is transported by air currents when spray-coating is performed using a centrifugal force generated by rotation.SOLUTION: A construction method is a continuous construction method that uses a device equipped with a mechanism whereby a granular fire-resistant material and water are supplied continuously, and a kneaded substance of the fire-resistant material and the water is projected toward the object to be constructed. The method includes: a step in which water is injected into and mixed with a fire-resistant material; a step in which the mixture of water and fire-resistant material is further mixed while being transported by means of a mixture transport path; and a step in which the mixture is kneaded to produce a kneaded substance by means of the rotation of an outer tube and a rotating part.

Abstract: PROBLEM TO BE SOLVED: To provide an aluminum oxycarbide composition capable of suppressing oxidation of AlOC during use to maintain advantageous effects of AlOC for a long time.SOLUTION: In an aluminum oxycarbide composition comprising AlOC crystals, the AlOC crystals have an average diameter of 20 μm or more, based on an assumption that a cross-sectional area of each AlOC crystal during observation of the aluminum oxycarbide composition in an arbitrary cross-section thereof is converted into a diameter of a circle having the same area as the cross-sectional area. This aluminum oxycarbide composition can be produced by subjecting a carbon-based raw material and an alumina-based raw material to melting in an arc furnace and then cooling within the arc furnace.
