  • Method of scrapping furnace bottom section of blast furnace
    Patent number: 6479011
    Abstract: A solidified residual iron within a blast furnace is suspended up by employing a shell suspending device fixed to a tuyere arranged in a lower end portion of an upper portion of a furnace body suspended by a lift jack and a solidified residual iron suspending band, thereafter is descended by employing the lift jack and is mounted on a horizontally moving table. Subsequently, the horizontally moving table mounting the solidified residual iron thereon is moved onto a furnace outer truck rail from a furnace inner truck rail so as to be taken out of the furnace by operating a center hole jack arranged near the furnace outer truck rail, whereby an operation of taking out the solidified residual iron within the blast furnace out of the furnace is economically performed for a short time.
