CONTINUOUS SURFACE TREATMENT METHOD FOR STEEL WIRE
A method to form a phosphate coating on a steel wire, the method including: continuously forming a phosphate coating on a steel wire before being subjected to cold forming; and a descaling of jetting slurry including grit-like abrasive particles onto the steel wire before forming the phosphate coating, thereby producing a new surface on the steel wire. The method can further include a preheating of the steel wire after the descaling and before the coating treatment. The method makes it possible to form a phosphate coating on a steel wire in a short time with high productivity without causing significant forming deterioration on the surface of the steel wire.

Electric wire or cable
There is provided an aluminum-alloy material having sufficient electric conductivity and tensile strength as a wiring material and excellent in wire-drawing property, and an electric wire or cable using the same. An electric wire or cable includes an aluminum-alloy strand formed of an aluminum-alloy including Fe: 0.1% by mass or more to less than 1.0% by mass, Zr: 0 to 0.08% by mass, Si: 0.02 to 2.8% by mass, at least one of Cu: 0.05 to 0.63% by mass and Mg: 0.04 to 0.45% by mass, and the remainder being aluminum and unavoidable impurities.
Method of thermally drawing structured sheets
A method of drawing a material into sheet form includes forming a preform comprising at least one material as a large aspect ratio block wherein a first transverse dimension of the preform is much greater than a second transverse dimension substantially perpendicular to the first transverse dimension. A furnace having substantially linearly opposed heating elements one spaced from the other is provided and the heating elements are energized to apply heat to the preform to create a negative thermal gradient from an exterior surface along the first transverse dimension of the preform inward toward a central plane of the preform. The preform is drawn in such a manner that the material substantially maintains its first transverse dimension and deforms across its second transverse dimension.

STEEL WIRE SURFACE TREATMENT METHOD AND SURFACE TREATMENT LINE
The steel wire surface treatment method of the present invention is a method for continuously treating the surface of a steel wire and includes: a descaling step P2 in which scale adhering to the surface of a steel wire is removed by subjecting the surface of the steel wire to wet blasting; a coating film treatment step P5 in which a coating film is formed on the surface of the steel wire after completion of the descaling step P2; and a water amount controlling step P3 in which the water amount on the surface of the steel wire immediately before performing the coating film treatment step P5 is adjusted to a prescribed water amount.
Wire drawing method

Systems and methods for drawing high aspect ratio metallic glass-based materials
Systems and methods for drawing high aspect ratio metallic glass-based materials are provided. Methods of drawing a high aspect ratio metallic glass-based material are premised on stably drawing high aspect ratio metallic glass-based material from a preform metallic glass-based composition, accounting for the relationships between: the desired formation of an amorphous structure that is substantially homogenous along the majority of the length of the drawn high aspect ratio material; the desired final geometry of the drawn high aspect ratio material; the nature of the force that is used to draw the molten metallic glass-based composition; the velocity at which the high aspect ratio material is drawn; the viscosity profile of the material along its length as it is being drawn; and/or the effect of temperature on the metallic glass-based material. A precise thermal treatment is imposed along the forming length of the drawn material so as to enable a steady state drawing process, the precise thermal treatment being based on: the desire to develop a substantially same amorphous structure along the length of the drawn material; the desired final geometry for the drawn material; the nature of the force used to draw the material; the velocity at which the material is being drawn; and/or the thermal treatment's impact on the viscosity profile of the material along its length as it is being drawn.
