REFRACTORY PRODUCTS MANUFACTURING METHOD Russian patent published in 2020 - IPC C04B35/18 C04B35/622 C04B35/66 

FIELD: metallurgy; machine building.

SUBSTANCE: invention relates to production of refractory articles and can be used in metallurgy and machine building. In the method of producing refractory articles, involving crushing slag of aluminothermic reduction of metal, obtaining a mixture by mixing crushed slag with binder, sintering mixture, slag is crushed to fraction of not more than 4 mm, slag of aluminothermic reduction of metal, containing, wt. %: aluminium oxide 72–85, iron oxide 6–15, silicon oxide 3–4, magnesium oxide 3–4, manganese oxide 1.6–2, impurities are the rest, binder used is fluorite in following ratio of components of mixture, wt. %: said slag 98–99, fluorite is the rest, mixture is sintered at temperature of 1300–1400 °C.

EFFECT: technical result is production of refractory articles with refractoriness of 1900 °C.
