FIELD: metallurgy.
SUBSTANCE: washing agglomerate contains iron monoxide 28.0-60.0; silicon dioxide 23.0-30.0; magnesium oxide 0.5-9.0; aluminium oxide 1.7-6.0; calcium oxide 1.0-12.5; iron oxide 5.0-25.0 and iron silicates. At that, total iron content in agglomerate is 35.0-51.0%, and content of iron silicates is 30.0-60.0%. In order to produce washing agglomerate the charge containing iron, silicone, magnesium, aluminium and calcium, and consisting of iron-bearing component, flux and solid fuel, is mixed, granulated, charged to sintering trucks and sintered. Silica-containing material is used as flux. Quantity of solid fuel in charge is 6.5-10.0%.
EFFECT: increasing washing properties of agglomerate.
