Abstract:
PROBLEM TO BE SOLVED: To provide a refractory composition capable of obtaining a refractory excellent in stability of forming and formability, high in residual carbon amount and good in corrosion resistance. SOLUTION: The refractory composition is prepared by blending fireproof aggregate with phenol resin as binder component and ring compound, the boiling point of which is >=130 deg.C in atmosphere.
Abstract:
PROBLEM TO BE SOLVED: To provide a cleaning method which efficiently removes a residue stuck in the mold of a molding machine without hindering a molding process. SOLUTION: In the molding machine 1 having a charger 14 which has an upper mold liner 6 and a lower mold 4, holds blending packed in the lower mold 4 between the upper mold liner 6 and the lower mold 4, presses the blending, reciprocates between a standby position and a filling position, and packs the blending in the lower mold 4, the charger 14 is provided with a rotary brush 16 which abuts on the upper mold liner 6 and a lower mold liner 9, an upward cleaning nozzle 17 and a downward cleaning nozzle 15 which jet cleaning liquids toward the upper mold liner 6 and the lower mold liner 9, the lower mold liner 9 is cleaned when the charger 14 advances, so that the upper mold liner 6 is cleaned when the charger 14 retreats.

Abstract:
PROBLEM TO BE SOLVED: To provide a blending filling method which fills homogeneous blending in uniform density even if a mold to be filled has a special shape. SOLUTION: In the blending filling method in which blending is put in a charger 14 having a cylindrical casing 15 and a stirring means (rotary arm 17 and stirring rod 18) rotating around the central axis of the casing 15, the charger 14 is moved horizontally toward a mold, and the blending in the casing 15 is dropped into the space 27 of the mold at a first stop position where the rotary shaft 16 of the casing 15 does not cover the space 27, the charger 14 is stopped to turn the blending in the casing 15 dropped into the space 27 of the mold.
