  • Method and installation for producing steel products with optimum surface quality
    Patent number: 8021599
    Abstract: A method for producing steel products (1) with optimum surface quality wherein the molten steel (1b) is produced in a process route (10, 100; 12; 13) that is selected according to a desired final microstructure (9), by melting in a furnace (2b) with an electrode system (31), and in a vacuum degassing system; or by melting in a furnace installation (35) or an individual furnace vessel (30), in a ladle furnace (25), and in a differential-pressure vacuum degassing system (43); or by melting in a furnace (2b) with additions of alloying materials (26), a partial-quantity degassing in the ladle furnace (25), or a vacuum degassing system (27) and a ladle degassing (27).
    Type: Grant

  • Method of degassing molten steel
    Publication number: 20040154437
    Abstract: Molten steel is degasified under vacuum and in the first 5 minutes of the degasification to improve and accelerate the degasification solids in the form of pieces of a size of 2 to 50 mm are introduced into the melt.
