<p>FIELD: metallurgy. SUBSTANCE: proposed briquette contains steel oxide, carbon-containing material and binder. Broken electrodes are used as said carbon-containing material, mixture of silicium dioxide, calcium dioxide, sodium dioxide and aluminium oxide is used as said binder. Ratio of said ingredients are (mass %) as follows: broken electrodes 10-30, binder 1-10. EFFECT: increases strength of briquette, improves quality of cast iron and steel.</p> |
