METHOD FOR MELTING A BATCH IN AN ELECTRIC ARC FURNACE |
摘要 |
A method for melting a batch in a furnace, particularly an electric furnace for melting scrap to produce steel, wherein melting energy is supplied to the load and fumes are post-combusted by injecting an oxygen-containing gas into the space above the batch in the furnace. The oxygen-containing gas is injected in a number of jets each having a flow rate of around 50-1200 Nm<3>/h and a discharge velocity at the injectors (11, 12) of around 10-150 m/s. |
