FIELD: chemistry, metal melting.
SUBSTANCE: invention concerns metallurgy and can be applied in melting industry. In the process of melting blended material in a gas cupola-furnace, natural gas is burnt at the air consumption rate within 1.4-1.8. Carbonaceous material in an idle fireproof charge comprises 50-100%.
EFFECT: reduced natural gas consumption for melting.
