    2021-5-7 · The electric zinc smelting furnace is actually a resistance arc furnace. The electric energy supplied by the graphite electrode is converted into heat energy through the material slope and slag resistance to keep the slag temperature at 1250~1350. The furnace gas composed of zinc vapor and CO after electrothermal reaction enters the condenser to condense the zinc vapor into liquid zinc.
