摘要

FIELD: metallurgy.;SUBSTANCE: cupola furnace includes shaft with loading opening. Recuperator made of external and internal coaxial pipes is located above the loading opening in the shaft. Recuperator is equipped with spiral head piece and with expansion joint in upper part. Expansion joint is made in the form of horizontal plates one of which is attached to external pipe and the other one to internal pipe of recuperator. Useful height of cupola furnace is Hn=2.81-3.1√D, where D - cupola furnace diameter.;EFFECT: increasing heat efficiency of cupola furnace and reducing heat pollution of atmosphere.;1 dwg
