FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and can be used for disposal of main pipelines to be processed to hoop, mainly, rolled wire with application of mobile plant. Dismantled pipe is heated to 970-1150°C at its transfer through straight-through inductor at the rate of 30-150°C/s and cut in helical line at inductor exit. Strip blank results therefrom. Cutting is performed in cutting-off pass between two rolls their rotational axes being turned through an angle relative to the pipe lengthwise axis. Magnitude of said angle is predefined from cited equation subject to pipe radius and strip blank preset width. Then, blank is cooled in guide at the rate of 15-45°C/s to temperature of 950-860°C and fed to continuous rolling mill. Blank is rolled to rolled 5.0-12.0 mm diameter wire at 830-910°C. Then, rolled wire is cooled at accelerated cooling line to 320-560°C and coiled.
EFFECT: possibility of production of rolled wire in 2,0 t heavy coils, high mechanical properties, yield of 99,5%.
