1. General view of the modernized furnace
2. Working window of the mnemonic diagram of furnace control program
3. Heat-treated metal in the modernized furnace (normalizing annealing process)
The furnace is meant for heat treatment of 15 tons of metal. The furnace efficiency at a rated charging is 46%, which is consistent with the best world analogs. Having modernized the furnace, the specific natural gas discharge for metal heat treatment decreased 4-5 times (depending on the charge weight and heat treatment regime).
