    摘要： Excellent characteristics concerning slag penetration-resistance, corrosion-resistance, and structural stability on usage of lining-refractory such as equipment for desiliconizing molten iron, a ladle for steel-making, a RH equipment are obtained. Unshaped refractories provide fine particles of under 0.75mm diameter, and aggregate of 0.75-10mm. Furthermore, the fine particles contain 10-35 mass % content of MgO, to the total mass % of the fine particles. Even furthermore, the sum total amount of MgO and Al2O3 is more than 90 mass %, to the total mass % of the fine particle. Additionally, such fine particles has 5-40 mass % of particles made of periclase-spinel, as a source of MgO, to the total mass % of the unshaped refractories. And, the aggregate comprises at least one selected from the group consisting of particles made of alumina and particles made of spinel.

    摘要： The side dam comprises a layer in contact with the molten metal constituted by a refractory material of fibrous structure and composed mainly of alumina and silica, and a second layer which is provided behind the first layer and composed of compact refractory material. The fibrous layer ensures the thermal insulation and the compact layer acts as a safety plate. The invention permits the construction of side dams which are capable of both durably ensuring the sealing of the molten metal and preventing untimely solidifications of the metal upon contact with these side dams. The invention is preferably applied to the continuous casting between rolls of hard metals having a high melting temperature, such as iron and its alloys.

    摘要： The invention concerns a multiphase alumina-based material formed by a matrix of corundum in which microcrystalline phases of aluminium oxycarbide, aluminium oxynitride and aluminium oxycarbonitride are homogeneously dispersed. The combined carbon content is between 0.05 and 5% and the combined nitrogen content is from 0.05 to 5% by weight. The material can be produced by the controlled injection of carbon and nitrogen into a molten alumina bath. The material is used for abrasive products and refractory products with high levels of performance.
