SINTER PRODUCTION CHARGE Russian patent published in 2019 - IPC C22B1/243 

FIELD: metallurgy.

SUBSTANCE: invention relates to the ferrous metallurgy and can be used in the sinter production in ferrous and nonferrous metallurgy, in particular in the blast furnace production. Sinter production charge contains a mixture of ore material, flux, coke breeze, MMS concentrate and binder. As the binder, it contains the Polymer CB powdered polymer additive, made in the form of the sodium and polyalkylated derivatives mixture, in the following ratio, wt.%: ore material – 20.0–30.0, flux – 0–10.0, coke breeze – 2.0–8.0, CB polymer – 0.1–3.0, MMS concentrate is the rest being.

EFFECT: enabling increase in the sinter burden components dispersed particles adhesion forces, improvement in the sinter burden combining properties, increase in the sinter strength and reducibility quality.
