摘要： Iron ore is continuously converted to steel by introducing the ore into a shaft furnace of substantially equal cross-sectional width and thus forming a column of the charge therein; introducing a reducing gas into the furnace and exposing the bottom portion of the charge column from below to the heat of an electric arc the source of which is centrally disposed in the bottom of the furnace and thus causing the gradual super-heating and melting of the bottom portion of the charge so as to form a dome-shaped cavity at the bottom of the charge column while the column gradually moves downward under the force of gravity and collecting and tapping the formed molten steel at the bottom of the furnace.

摘要： A charge is admitted into a shaft furnace so as to form a charge column therein. The lower end of the column is melted with a flame and the charge moves downwardly by gravity as melting proceeds. The flame is generated by admitting one or more streams of oxygen and one or more streams of fuel into the furnace. A stream of oxygen and a stream of fuel are admitted into the furnace as a pair and in such a manner that the respective oxygen stream is surrounded by the respective fuel stream. This procedure provides the result that the fuel entering the furnace withdraws so much heat from the surroundings that water-cooling of the burners may be eliminated. Moreover, the withdrawal of heat from the surroundings serves to cool the furnace wall in the regions of the burners sufficiently for molten material flowing on the furnace wall in these regions to solidify. Consequently, protuberances are formed on the furnace wall. The charge column is supported on these protuberances which provides the advantage that the charge column does not contact the molten material at the bottom of the furnace. In addition to this effect, the protuberances serve to protect the furnace lining by forming a thermal shield therefor. The size of the protuberances can be controlled by partially pre-mixing the oxygen and the fuel and by regulating the rate of expansion and flow rate of the oxygen and fuel. In order to permit the oxygen and fuel to be admitted into the furnace in the manner outlined, the burner or burners may be constructed with plural openings which are arranged such that the opening through which the oxygen enters the furnace is at least partially surrounded by the opening or openings through which the fuel enters the furnace. One embodiment contemplates an annular burner having a central slit for the admission of oxygen into the furnace and two slits for fuel which flank the oxygen slit. Another embodiment contemplates a plurality of individual burners which are constructed in the form of double-walled conduits.

摘要： A method of and apparatus for fabricating clad ingots or clad slabs includes a hollow body which corresponds to the dimensions of a finished slab and which has at least one side plate of cladding material and other thinner side sheets forming an upright tubular hollow body which is inserted into a larger ingot mold. Refractory insulating material is disposed between the bottom end of the hollow body and the bottom wall of the mold and between the sides of the hollow body and the sides of the mold, the hollow body being subsequently charged with a molten base metal. Prior to inserting the hollow body into the mold, the bottom end thereof is sealed closed by a bottom wall and a cover plate is placed on the top end of the hollow body.
