FIELD: metallurgy.
SUBSTANCE: briquette for washing blast furnace includes flux materials, scale as iron-bearing material, Portland cement as binding agent and hardening catalyst. Slags of blast smelting of nickel and/or copper matte are used as flux materials, and solution of calcium chloride and/or solution of calcium nitrate is used as hardening catalyst. In order to obtain briquette, iron-bearing, flux components, binding agent and hardening catalyst are added to charge; charge is mixed and pressed in roller briquette press at specific pressure of 30-100 MPa.
EFFECT: obtaining briquette with high washing characteristics at its being used during blast-furnace smelting with low costs.
