Abstract
Способ производства горячекатаного проката из слитков, полученных на машине непрерывного литья (МНЛЗ) криволинейного типа, включающий формирование в кристаллизаторе поверхностного слоя слитка, вытягивание слитка из кристаллизатора, формирование слитка в цилиндрическую спираль, отделение заготовки от слитка и прокатку выпрямленной заготовки, отличающийся тем, что непрерывно-литой слиток, сформированный в цилиндрическую спираль, после выхода с МНЛЗ вводят в теплоизолирующее устройство на скорости разливки металла МНЛЗ, отделяют заготовку от слитка, термостатируют с одновременной транспортировкой к прокатному стану и последующей подачей заготовки на скорости прокатки в прокатный стан, при этом термостатирование выполняют при температуре, близкой к температуре кристаллизации металла, а слиток вводят в теплоизолирующее устройство по винтовой траектории, соединяя эту операцию с выдачей слитка из МНЛЗ, после чего отделяют заготовку от слитка и транспортируют ее в теплоизолирующем устройстве к прокатному стану, придавая заготовке колебательные движения с амплитудой от 1,5 R до 6,0 R, где R- радиус цилиндрической спирали, при этом заготовку выдают из теплоизолирующего устройства в прокатный стан по винтовой траектории со скоростью, тождественной скорости прокатки в первой клети прокатного стана. A method for the production of hot rolled products from ingots obtained on a continuous casting machine (CCM) of a curvilinear type, comprising forming a surface layer of an ingot in a mold, drawing an ingot from a mold, forming an ingot into a cylindrical spiral, separating the workpiece from the ingot and rolling the straightened workpiece, characterized in that a continuously cast ingot formed into a cylindrical spiral, after exiting from the continuous casting machine, is introduced into the heat-insulating device at the casting speed of the continuous casting metal, and the bar is separated The lead from the ingot is thermostated with simultaneous transportation to the rolling mill and subsequent supply of the workpiece at a rolling speed to the rolling mill, while thermostating is performed at a temperature close to the crystallization temperature of the metal, and the ingot is introduced into the heat-insulating device along a helical path, connecting this operation with delivery an ingot from a continuous casting machine, after which the workpiece is separated from the ingot and transported in a heat-insulating device to the rolling mill, giving the workpiece oscillatory movements with an amplitude of 1.5 R to 6.0 R, where R is the radius of the cylindrical spiral, and the billet is drawn from the heat-insulating device into the rolling mill along a helical path with a speed identical to the rolling speed in the first stand of the rolling mill.
