摘要： An electric arc furnace has its side wall lining protected against arc-flare by an external magnet forming a magnetic flux field on the inside of the lining where arc-flare protection is required, and a supply of ferro-magnetic particles are fed downwardly through this flux field for the purpose of forming a layer of the particles held against the lining. The particles are continuously fed to replace particles which, because of heating, become non-magnetic and fall. In this case, the magnet is an electromagnet having an iron core and solenoid windings which produce a more uniformly and widely spread layer of the particles on the side-wall lining's inside.
