Latest Patents

Yoshitsugu holds a patent for a refractory material and casting nozzle. This invention includes a refractory product that comprises CaO component-containing refractory particles and MgO component-containing refractory particles. The chemical composition of the refractory material is measured after it has undergone heating in a non-oxidizing atmosphere at 1000°C. It contains one or more metal oxides, such as BO, TiO, VO, PO, and SiO, in a total amount of 0.1 to 5.0 mass percent, along with free carbon in an amount of 2 to 35 mass percent. The remainder consists of CaO and MgO, with a mass ratio (CaO/MgO) ranging from 0.1 to 1.5. Microscopic observations at room temperature reveal that an inorganic film comprised of CaO and the metal oxides forms on the surfaces of the refractory particles, with a thickness of 0.1 to 25 μm.
