摘要： The present invention provides a technique of applying a CaO-containing material to a nozzle unit for casting of aluminum-killed steel, in such a manner that the amount of large-size alumina inclusions in slabs can be reduced irrespective of nozzle type, such as single-part type or multi-part type. The amount of large-size alumina inclusions in slabs obtained using a single-part type or multi-part type nozzle unit, which has an inner hole to be used for pouring molten steel from a tundish to a mold therethrough and CaO-containing refractories applied to a surface of the inner hole, has a strong correlation with the entire surface area of the inner hole of the nozzle unit and the amount of CaO contained in the employed refractories. According to the present invention, 50% or more of the entire surface area of the inner hole of the nozzle unit is formed of refractories containing 20 mass % or more of CaO to allow the amount of large-size alumina inclusions to be reduced.

摘要： A carbon-containing refractory is provided, which can improve the thermal shock resistance, the abrasion resistance, and the corrosion resistance without degrading the oxidation resistance.In a carbon-containing refractory composed of a refractory aggregate, a carbon based raw material, and a carbon bond connecting between the refractory aggregate or the carbon based raw material, transition metal-containing nanoparticles having particle diameters of 1,000 nm or less and containing a transition metal are contained in the above-described carbon bond while being dispersed. When the carbon-containing refractory is heat-treated, flexible structures of carbon fiber-shaped textures having diameters of 50 nm or less are formed in the inside of a carbon bond and, thereby, an increase in strength, a reduction in modulus of elasticity, and a reduction in thermal expansion coefficient are facilitated. Therefore, a carbon-containing refractory exhibiting high thermal shock resistance, high abrasion resistance, and high corrosion resistance are provided.

摘要： Disclosed is a magnesia-carbon based sleeve brick for steelmaking converters, which is obtained by adding, to a refractory raw material mix containing 60 to 95 mass % of a magnesia raw material and 5 to 20 mass % of graphite, a metal powder of one or more selected from the group consisting of Al, Si, Mg, Ca, Cr and an alloy thereof, in an amount of greater than 3 to 6 mass %, and an organic binder, in addition to 100 mass % of the refractory raw material mix, and subjecting the resulting mixture to kneading, forming and heat treatment, wherein the sleeve brick is used under a condition that a thickness thereof is set at 70 mm or less. This makes it possible to prevent cracking which would otherwise occur in the sleeve brick itself, to allow the sleeve brick to have enhanced durability. One or more selected from the group consisting of B, B4C, MgB2, CaB6, and CrB may be further added in an amount of 0.1 to 3 mass %, in addition to 100 mass % of the refractory raw material mix, to enhance strength and oxidation resistance and further enhance the durability. The magnesia raw material may comprise a first particle fraction having a particle diameter of greater than 10 to 500 μm and occupying 20 to 50 mass % in the refractory raw material mix, and a second particle fraction having a particle diameter of 10 μm or less and occupying 5 mass % or less in the refractory raw material mix, to additionally enhance corrosion resistance and thermal shock resistance.

摘要： A configuration in which particles of pitch 2 having a softening point in the range of 70 to 200° C. and a diameter equal to or smaller than 30 μm are held on the surfaces of particles of a refractory raw material 3 having a diameter equal to or smaller than 50 μm is employed. This pitch-containing refractory raw material 1 can be used with the pitch being in a fine-particle form without any aggregation even after the long-term storage. Using it as a part of a raw material formulation allows the fine particles of pitch to be uniformly dispersed during the mixing or kneading process. The resulting carbon-containing refractory has an excellent corrosion resistance. It also provides suppressed increase in the Young's modulus while maintaining the level of strength, thereby being excellent in thermal spalling resistance even with the carbon content ratio being low.
