摘要： PURPOSE:To obtain a uniform excution material having dense texture by injecting water in a transport pipe in the vicinity of the execution spot to apply water adding and mixing treatment to a refractory material and subsequently feeding and kneading the refractory material while separating feed air. CONSTITUTION:A refractory powder material is quantitatively and continuously delivered from a material delivery device 1 and the delivered material is fed through a material hose 7 by compression air. In this case, before the fire- resistant powder material 2 is charged in a quantitative delivery device 3, the fire-resistant powdery material preliminarily kneaded in a semi-wet state along with water corresponding to 1-3wt.% of a necessary execution water amount by a mixer is fed or water corresponding to 1-3wt.% of the necessary execution water amount is added to the fire-resistant powdery material from a primary water injection port 8 provided on this side separated from a nozzle water injection orifice 9 by at least about 10 m or more. The fire resistant powdery material preliminarily kneaded during the feed through the hose is fed in a semi-wet state and a necessary predetermined amount of the remaining water is added to the fire-resistant powdery material from the nozzle water injection orifice 9 to be kneaded therewith in a nozzle 14.

摘要： PURPOSE:To enable refractory blocks with denseness to be manufactured by applying vibration force and press force to a monolithic refractory substance poured into a mold. CONSTITUTION:In a manufacture of refractory blocks through pressure dehydration vibration molding characterized such that a mold 2 having a film 8 with a plurality of drainage ports 7 and a filtration paper or a hole is provided on a vibration table 1, and a monolithic refractory substance 3 is poured therein so as to be pressure-dehydrated by a pressure plate 4, vibration is simultaneously applied thereon in order that pressure sufficiently spreads in the inner part thereof during pressurization. Such time is limited to be in the range of from 30min. to the time when the monolithic refractory substance material cures. By keeping the continuous vibration during pressurization, frictional forces and cohesive forces are weakened, with the result that pressure can sufficiently be spread in the inner part thereof.
