<p>PURPOSE:To accurately separate a wire rod with a long as-rolled part by operating a wire rod rolled length based on the stock weight and the sectional area of the wire rod and giving a cutting command based on a wire rod rolling speed given by a rolling speed measuring instrument and the above wire rod rolled length. CONSTITUTION:A separation accuracy of a wire rod is improved by accurately estimating an as-rolled length by use of continuously measured results of a wire rod sectional area. A stock 1 is weighed by a scale, is finished by a wire rod block mill 4 through a heating and a rolling process, is made to be a coillike shape by a forming device 8, and is wound into a coil by a storage device 11. A profile meter 7 and a steel stock thermometer 6 are installed on the outlet side of the block mill 4 to continuously measure sectional areas and stock temps. after the wire top end is passed by the meters and to average the areas and temps. after the wire rear end passes by the meters and to obtain an as-rolled length. Separation timing is found based on the above as-rolled length and a cutting command is given to a cutter 9 to cut the wire coil into two pieces.</p> |
