WATER-COOLED BURNER UNIT FOR ARC STEEL-MAKING FURNACE Russian patent published in 2025 - IPC F27B3/22 F27D1/12 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and concerns design of water-cooled units of gas-oxygen burners installed in arc steel-making furnaces (ASF). Water-cooled unit of the burner contains at least one hole for installation of the burner, the first and the second cooling circuits. Unit is equipped with a housing, the head part of the water-cooled unit is made in the form of a separate part – a detachable front panel docked with the housing and having no tight connection to it, water-cooled unit housing and detachable front panel have each individual cooling circuit, respectively, the first cooling circuit and the second cooling circuit, wherein second cooling circuit of detachable front panel is supplied in series or in parallel with first cooling circuit of water-cooled unit housing.

EFFECT: invention makes it possible to create a water-cooled burner unit with a removable front panel for quick replacement during repair, as well as to reduce labour and time costs.
