Title: Furnace for remeling highly impure steel scrap
Inventor: ROSSAK ALFRED
IPC: C21C5/56
Filed: 1968-10-19
Abstract: Furnace heated by several high-pressure oil or gas burners, the combustion gases being injected directly into the steel melt and, on reaching the furnace roof (which is insulated and water-cooled), deflected 90 over a vibratory water-cooled grate. The scrap, which is fed continuously onto this grate, is purified and preheated to 1200 C by the gases. which then pass through a boiler and recuperator and are emitted into the atmosphere after purification. Earth and non-ferrous metal impurities, with a melting point below 1250 C, are shaken or melted off the scrap on the grate, the hot scrap falling or sliding into the bath to melt completely. High-pressure oil burner, for injecting fuel gases at above 2000 C pref. has hollow casing made from a highly heat-resistant alloy cooled by metal vapours, preferably sodium. Low burner temp. enables addition for purification of the raw steel (such as calcium carbide) to be added in powder form to the combustion air.
