    摘要: Cold-rolled, non-microalloyed carbon manganese steel (0.11% to 0.18% C, 1.20% to 1.40% Mn) is preheated at 700.degree. to 1000.degree. F., heated to 1500.degree. to 1575.degree. F., and quenched to 800.degree. to 950.degree. F. in a continuous process to develop minimum yield strength of 70,000 psi, minimum tensile strength of 85,000 psi, and 14% minimum elongation.

    摘要: A steel wire to be coated is brought across the graphite spout of a crucible filled with a bath of molten metal, after having first been heated in a tubular duct filled with protective gas by an electric coil powered by a high frequency source to a temperature lower than that of the molten metal contained in the spout. The melting point of this metal is greater than the austenizing temperature of the steel. On leaving the spout, the coated steel wire is then cooled in a controlled manner to avoid hardening, for example, if it is a question of a steel of approximately 0.7% carbon, by having it spend several seconds in a fluidized bed whose temperature is maintained at a temperature of the order of 550.degree. C.

    摘要: A process for manufacturing pearlitic steel wire, particularly with fine diameters and for use in reinforcing rubber vehicle tires. The wire is subjected to a patenting treatment before being drawn down to its final diameter, but is held at the transformation temperature for no more tha 5 seconds after transformation has taken place. Such a step renders the wire capable of being subjected to true strains of more than 3.0 and achieving tensile strengths of 3000 Nmm.sup.-2 or more. The wire may be cooled from the transformation temperature via a first stage in which the temperature is reduced to 400.degree. to 450.degree. C. over a period of time not less than 3 seconds.

    摘要: A hot steel rod which issues from the last pass of a rod mill is coiled at a level above a bath of molten salt and successive coils are caused to descend in the bath toward a platform on which they accumulate to form a bundle. The coils are out of contact with each other during the initial stage of movement toward the platform for a period of time which is long enough to insure that their material undergoes desirable structural changes. The temperature of the bath is maintained within a predetermined range by an adjustable induction heater which surrounds the vessel for the bath and by circulating a stream of molten salt through one or more heat exchangers located outside of the vessel. The stream is withdrawn close to the bottom zone and is returned into the upper zone of the bath. Alternatively, the vessel may contain a mammoth pump which is operated by water and steam. The steam withdraws a stream of molten salt from the vessel and is thereupon separated from withdrawn molten salt before the latter is returned into the bath. The separated steam is condensed and is used to rinse bundles (after the bundles are removed from the bath) prior to readmission into the mammoth pump. The bundles are thereupon caused to pass through a wire die.
