MANGANESE FLUX FOR CONVERTER PRODUCTION AND CHARGE FOR PRODUCTION OF MANGANESE FLUX Russian patent published in 2018 - IPC C21C5/36 C21C5/28 

FIELD: metallurgy.

SUBSTANCE: invention can be used to produce manganese flux for converter production. The flux contains, wt %: CaO 58.0-63.5; MnO 10.0-15.0; Al₂O₃ 2.5-4.0; SiO₂ 10.0-16.0; Fe₂O₃ 3.0-5.0. Additionally, it contains magnesium oxide in amount of 3.0-8.5 wt %. Charge for production of manganese flux contains manganese limestone as a manganese component, and a cement clinker as a lime-containing component with the following component ratio, wt %: cement clinker up to 6; the rest is manganese limestone. Additionally, it can contain magnesium-containing material in the form of brucite or dolomite.

EFFECT: invention makes it possible to increase smelting efficiency by providing low melting point of the flux, while reducing the likelihood of slag foaming, reducing dust losses and enhancing stability of converter lining.
