摘要： The present invention is a composite material, a process and a product formed by the process. The composite is formed by a process that includes forming a fibrous structure comprising fibers into a preform, coating the fibers of the fibrous structure preform with elemental carbon to impregnate that preform, infiltrating the preform with boron carbide to form an impregnated green body. The impregnated green body is infiltrated with liquid naphthalene or other carbon precursor, which is thereafter pyrolyzed to form a carbon char. Then, the char infiltrated green body is infiltrated with molten silicon to form a continuous matrix throughout the composite. The silicon in the continuous matrix is reacted with the carbon char to form silicon carbide.

摘要： A carbonaceous refractory material is produced by adding an organic binder to a mixture containing a carbonaceous material comprising a carbonaceous raw material comprising calcined anthracite, calcined coke, artificial graphite or natural graphite or a mixture thereof at 50 to 85% as the principal raw material, alumina particle at 5 to 15%, metal silicon particle at 5 to 15%, and one or two or more of titanium carbide powder, titanium nitride powder and titanium carbonitride powder at 5 to 20% in total, kneading and molding the resulting mixture and baking the molded article under non-oxidizing atmosphere. By using the carbonaceous refractory material as the inner lining material for the side wall and bottom of blast furnace hearth, the consumption of the inner lining material due to the dissolution thereof in melted pig iron can be decreased, and simultaneously, the abrasion due to the flow of melted pig iron can be decreased, which works to prolong the life of the blast furnace.

摘要： An improved submerged entry nozzle is provided which is useful in the casting of aluminum killed molten steel. The nozzle has an improved slagline sleeve or collar which surrounds the outer portion of the nozzle to protect it from corrosion during the casting process. The slagline sleeve is made from resin bonded zirconia/graphite which has been formulated so that upon curing of the resin to form resite, there is a reduction in the contractile tendency which results in a reduction in stress fracturing. The reduction of the contractile tendency and the resulting resistance to stress fracturing is achieved by adding an effective amount of calcium oxide to the resin-zirconia-graphite mixture which is used to form the sleeve.
