Abstract: A process and apparatus for providing metal material having an improved structure for forming into a desired article is disclosed herein. The improved structure is obtained by slurry casting a material into a continuous member and then hot working the slurry cast material. Upon reheating to a semi-solid state, the hot worked, slurry cast material will exhibit finer particles and fewer eutectic melting rosettes than would be exhibited by the slurry as-cast material in an unworked and heated condition. The hot working of the slurry cast material produces an article having a deformed structure exhibiting directionality.

Abstract: A method for preventing segregations in continuous casting by deforming the continuous strand plactically during the solidification in such a way that the cross-sectional area of the strand is physically reduced on a mount corresponding substantially to the solidification and cooling shrinkage of the material along the solidifying strand length. The method avoids upward or downward transport of melt in the solidifying strand. The reduction in most cases will be 2-6% and can be accomplished with apparatus having a number of pairs of strand reducing rolls or jets along the strand, to reduce it a number of times, each time less than the total desired reduction. The degree of reduction of the strand from casting to the final strand corresponds to the solidification and cooling shrinkage.

Abstract: A method and apparatus is described for forming non-ferrous, constant section, stackable auto-clamping blocks. The method advantageously utilizes a movable carriage having in addition to cutter means, a pair of jaws which are each generally shaped like a combined prism-trihedron to form mating surfaces in the formed blocks which allows stacking.

Abstract: In a method of rolling wide strip starting material, an ingot slab is rolled to the desired wide strip width by having its shorter sides edge-rolled. In order to save time, energy, material and investment capital, the ingot slab has a cross-section tapered towards the shorter sides in a wedge-shaped or curved manner at both edges, and is edge-rolled approximately to the wide strip width desired while filling out the rectangular shape.

Abstract: A lead or lead alloy strip useful for lattice plates of batteries, which is characterized by having recrystallized structure, and a method and apparatus for continuous manufacturing of said alloy strips directly from molten lead or lead alloy advantageously.

Abstract: A process for the production of a fine amorphous metallic wire is described, comprising melt-spinning an iron family element base alloy having an amorphous substance-forming ability to obtain a fine amorphous metallic wire, and passing the thus-formed fine amorphous metallic wire through a die so as to draw within an area reduction percentage range of from about 5 to about 90%. The thus-produced fine amorphous metallic wire of the iron family element base system is excellent in heat resistance, corrosion resistance, electromagnetic characteristics, and has excellent mechanical properties, such as breaking strength and a degree of drawing at break. Thus, it is very useful for various industrial materials such as electric and electronic parts, composite materials, and fibrous materials.

Specifically, process for controlling casting conditions on the basis of nitrogen contents in the molten steel and further controlling hot working conditions including heating conditions and working temperature.

Abstract: A method for preventing segregations in continuous casting by deforming the continuous strand plastically during the solidification in such a way that the cross sectional area of the strand is physically reduced corresponding substantially to the solidification shrinkage of the metal. The method avoids upward or downward transport of melt in the solidifying strand. The reduction in most cases will be 2-6% and can be accomplished with apparatus having a number of pair of strand reducing rolls or jets along the strand, to reduce it a number of times, each time less than the total desired reduction. The reduction of the strand from casting to the final strand follows the solidification shrinkage.

Abstract: Molten material is fed into an elongated outwardly open mold, moving in a predetermined path, and is thereafter conveyed by the mold movement at least partway through a region of such path over which a closure for the outward opening of the mold moves along therewith, the material concurrently being cooled to become solidified. The movements of such mold and closure cause the solidified material to be extruded through stationary die means disposed in such region. Such material may solder metal formed into a tube into which is inserted rosin, the same heat exchange medium being used both to cool the metal prior to its extrusion and to keep the rosin molten prior to such insertion thereof.

Abstract: A composite metal sheet or plate is manufactured by completely immersing an assembly of parallel or substantially parallel metal core sheets in molten metal at a lower melting point than the metal of the core sheets, and after the molten metal has solidified reducing the thickness of the ingot by hot rolling in a direction generally normal to the planes of the core sheets. The method has a particularly useful but by no means exclusive application in the production of reinforced aluminium alloy sheets and plates.

Abstract: A method for controlling a casting and rolling mill by measuring the speed of a cast strip between the casting machine and the first following rolling mill and regulating the speed of the casting machine directly proportional to the measured speed of the cast strip. It is thus possible to avoid auxiliary equipment required in prior art systems such as pinch rolls and a continuous furnace between the casting machine and the first following rolling mill. Furthermore no loop on the cast strip is required. As a result, great reductions in capital expenditures, the energy required to operate the line and the necessary space can be obtained.

Abstract: Improvements of a process for producing a non-directional electrical steel sheet free from ridging, which comprises making a molten steel into slabs by continuous casting, hot rolling the slab, cold rolling the hot rolled product into a final thickness by a single step, and subjecting the cold rolled product to decarburization annealing, said molten steel consisting essentially of not more than 0.02% C, 1.5 to 4.0% Si, not more than 1.0% Al, with the balance being Fe and unavoidable impurities, said hot rolling being done at a temperature in a range of from 900.degree. to 1100.degree. C.

Abstract: A process for the continuous manufacture of copper wire rod presenting both the good ductility of oxygen-free copper and the annealing capacity of the tough pitch copper, in which liquid copper is prepared containing from about 0.006 to 0.0095% by weight of oxygen, the said liquid copper is cast via an open pouring spout in a continuous casting machine having an inclined straight molding cavity for producing a continuous copper bar containing 0.01 to 0.02% by weight of oxygen and which consists of a shell of solid copper and a core of liquid copper, the said bar on leaving the casting machine is cooled by repeated and direct contact with a cooling agent for complete solidification and the solidified bar is guided towards a horizontal rolling mill known "per se" along a curved path the maximum curvature of which is less than 0.25 m.sup.-1, and the said bar is rolled into wire rod.
