METHOD OF OBTAINING METALLURGICAL BRIQUETTE Russian patent published in 2018 - IPC C10L5/06 C10L5/02 C10L5/10 C10L5/14 C10L5/16 

FIELD: metallurgy.

SUBSTANCE: invention discloses a method for producing metallurgical briquette which consists in mixing of starting components – carbonaceous material, which is coke breeze of MK-1 grade obtained by medium-temperature carbonization of brown coal, bicomponent binder containing resin and starch in ratio of (0.5–2):1, water with temperature of 1 to 99 °C, initial components are mixed in the following ratio, by weight: carbon-containing material – not less than 50; bicomponent binder – 8–20; water – the rest. After mixing, resulting briquette mixture is compressed and formed briquette is dried.

EFFECT: technical result consists in obtaining briquettes with low content of phosphorus oxides, high strength and low water absorption, which makes it possible to use them in the processes of silicon production in ore-thermal furnaces.
