マッド材
Document Type and Number:
Japanese Patent JP5215861
Kind Code:
B2
Abstract:
It is intended to provide a taphole mix capable of forming SiC bonds with minimum of an excess and a deficiency in components thereof, and excellent in drillability. A fine particle fraction having a particle diameter of 75 μm or less is comprised of three components consisting of a silicon nitride-based material, a carbon-based material, and roseki, or comprised of the three component, and one or more selected from the group consisting of an alumina-based material, a silicon carbide-based material, a rare-earth element oxide-based material, clay, a high-purity silica-based material containing SiO2 in an amount of 80 mass % or more, a boron compound-based material in an amount of less than 0.3 mass % with respect to 100 mass % of the silicon nitride-based material, and a metal powder in an amount of less than 10 mass % with respect to 100 mass % of the carbon-based material. Further, a total amount of 100 mass % of the three components in the fine particle range consists of 51 to 74 mass % of the silicon nitride-based material, 15 to 35 mass % of the carbon-based material, and 10 to 30 mass % of the roseki.
