Abstract: A tap hole mix for a blast furnace and the like containing essentially no binder comprising either water or one or more of tar, pitch and asphalt with or without the addition of a resin, which comprises refractory materials composed of grains of one or more of clay, chamotte, alumina, silicon carbide and the like and a carbonaceous material, a hardener comprising a novolak-type phenol resin to which a substance which produces formaldehyde by the thermal decomposition or a thermosetting resin is added in a definite proportion, and an alcoholic solvent. The present inventive tap hole mix is rapidly hardened or set, has excellent corrosion resistance and does not cause the occurence of unpleasant smoke and abnormal dusts.

Abstract: An apparatus for lining a container comprising a vibration-pressing mold to be placed on a refractory mix charged in the container, the outer shell of the mold being composed of a metal plate, a vibration-transfer frame provided on the inside of the metal plate, a plurality of vibrators provided on the vibration-transfer frame, an anti-vibration member provided on the upper end of the mold, a supporting frame for supporting the mold with the antivibration member inserted therebetween, a weight placed on the supporting frame, and a guide member for maintaining the mold in a stabilized posture during its sink-down into the refractory mix.
