摘要： A lining for a direct-current electric-arc furnace, in which at least part of that regions of said furnace which receives the melt is provided on the inside with an electrically conductive, refractory brick lining and a ring-shaped current conductor, on its outside, constitutes the opposite pole to the upper electrode centrally extending into said surface. The entire bottom area is covered with a refractory, insulating brick lining and a brick lining of graphite bricks is applied onto that brick lining in the radially outer wall region of the furnace. Located adjacent thereto in radially inward manner is an annular zone, comprising an electrically conductive, refractory brick lining. The central bottom area above said insulating brick lining is consittuted by a monolithic ramming mass. Furthermore, the material of the wall of said furnace above said brick lining of graphite bricks largely corresponds to that of said insulating brick lining at the hearth bottom.

摘要： 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.

摘要： A process for producing sponge iron from iron ore is described, which is reduced to sponge iron in a reduction shaft furnace by means of a hot reduction gas. For this purpose reduction gas at a temperature in the range 750.degree. to 900.degree. is introduced into shaft furnace (1) level with bustle plane (5) having been produced in a gasifier (2) then cooled and purified in a cyclone separator (12). Reduction gas is introduced below the bustle plane (5) at a temperature below that of the reduction gas introduced in the bustle plane and is preferably introduced into the shaft furnace (1) between 650.degree. and 750.degree.. Increased carburization of the sponge iron is obtained. Increased carbon separation also results through a volume increase, particularly by increasing the cross-section through the lower part of the shaft furnace. Carburization is also assisted in that the ratio of the reduction gas quantity supplied below the bustle plane is made as large as possible compared with the reduction gas quantity supplied in the bustle plane.

摘要： In a process for producing an iron melt, iron ore is reduced to sponge iron in a direct reduction zone. The sponge iron is melted in a meltdown gasifying zone while supplying carbon-containing material under gasification of the carbon-containing material to reducing gas and under formation of a slag. The reducing gas is injected into the direct reduction zone, is reacted there and is drawn off as a top gas. The reducing gas and/or the top gas is subjected to gas scrubbing and the sludges separated during scrubbing are admixed with binder and coal dust and subsequently are agglomerated. In order to be able to supply back to the direct reduction process in large amounts sludges incurring in the direct reduction of iron ore without disturbing the process course of the direct reduction in any way, the sludges separated during scrubbing are dehydrated to a residual moisture content prior to being further treated, coal dust and, as a binder, quick lime are then admixed to the sludges, the sludges subsequently are granulated and the granulate thus formed is supplied to the meltdown gasifying zone while increasing the basicity of the slag to a maximum of 1.25.

摘要： A conveying arrangement for the dosed conveyance of bulk material from one metallurgical vessel into another through a conveying channel. The conveying channel has an entry opening and a discharge opening. A conveyor worm is rotatably located in the conveying channel, extending at least from the entry opening to the discharge opening and including a first flight formed by a plurality of paddles. In order to be able to configure the conveyor worm as short as possible and to minimize gas streaming through the conveying channel, the conveyor worm, on its end associated with the discharge opening, has a second flight that is formed by a continuous helix extending at least over half a convolution.

摘要： 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.

摘要： A heating bath including molten metal is situated at an entry into a hot roll mill such that the metal stock entering the hot roll mill passes through the heating bath to acquire heat therefrom. A cooling bath including molten metal is situated at an exit from the hot roll mill such that the metal stock exiting from the hot roll mill passes through the cooling bath delivering heat thereto. The molten metal in each of the baths is caused to flow counter to the direction of passing of the metal stock therethrough to form within each bath a hotter fraction and a cooler fraction of the molten metal. The molten metal is circulated between the heating bath and the cooling bath so that a hottest fraction of the molten metal in the cooling bath is transferred to the heating bath and a coolest fraction of the molten metal in the heating bath is transferred to the cooling bath.
