  • Method for an improved energy input into a scrap bulk
    Patent number: 6402805
    Abstract: Provided is a method for improving energy input in heating and melting of a scrap bulk. The method includes burning a channel into a scrap bulk with a hot, oxygen-containing gas jet having a temperature of at least 500° C. Additional energy for the heating and melting of the scrap bulk is then input through this channel.
