Patent number: 5043011Abstract: A process for producing pig-iron is described involving the use of a reduction shaft furnace 1 and a melt-down gasifier 2. The sponge iron produced from iron ore in the reduction shaft furnace is fed into the melt-down gasifier and converted into a pig-iron melt. The gas produced in the melt-down gasifier is passed as reducing gas into the reduction shaft furnace both via a cyclone separator 11 and a line 12 and directly via a line 13. The top gas leaving the reduction shaft furnace, after passing through a scrubber 4, is largely returned via a CO.sub.2 scrubber 6, in which CO.sub.2 and H.sub.2 O are removed from the top gas, in such a way that it can be used for forming the reducing gas in the melt-down gasifier and also as a cooling gas for the reducing gas produced in said gasifier.Type: GrantFiled: January 30, 1990Date of Patent: August 27, 1991Assignee: Deutsche Voest-Alpine Industrieanlagenbau GmbHInventor: Rolf Hauk

Patent number: 5031687Abstract: A device is described for straightening a curved steel strand cast continuously by means of a casting wheel machine or a curved mold continuously casting machine. The strand is passed between straightening points with rolls, such as straightening, bending, guide, counter rolls and/or corresponding roll pairs, in accordance with a certain physical law, whereby at least two roll pairs applying bending moments to the strand are provided. The first roll pair is at the same time the roll pair located in the direction of travel of the strand directly downstream of the point of emergence of the strand from the casting machine or is formed by the casting wheel (of the curved mold) itself and a corresponding straightening roll. The second roll pair determines transition of the strand from a finite radius or curvature to a straight line (infinite radius of curvature) at the end of the bending zone. Between these two roll pairs other rolls can be located exclusively along the outside of the strand.Type: GrantFiled: May 13, 1988Date of Patent: July 16, 1991Assignee: Deutsche Voest-Alpine Industrieanlagenbau GmbHInventors: Georg Bollig, Walter Maschlanka, Hanns Feichtner
