COAL BRIQUETTE AND ITS PRODUCTION METHOD Russian patent published in 2023 - IPC C10L5/00 C10L5/06 C10L5/14 C10L5/26 C10L5/36 

FIELD: metallurgy.

SUBSTANCE: invention relates to briquettes used in metallurgy. A method for the production of coal briquettes for coking is proposed, including operations for mixing briquette components and forming briquettes, characterized by mixing coal fines with a particle size of no more than 1 mm, a yield of volatile substances of 0-38%, an ash content of 0-20% and a binder in an amount of 0-5% of the mass of coal fines for at least 5 minutes, forming briquettes with a size of no more than 35 mm in any direction, they are dried at a temperature of 10-150°C for 5-60 minutes, while its humidity is no more than 20%, and the output of the target fraction is at least 90%.

EFFECT: development of a method for the production of coal briquettes, providing the use of coal fines, for the purpose of further use of briquettes in the charge for coking.
