FIELD: plastic metal working, namely machine engineering processes, particularly straightening flat products from carbon and alloyed steels. SUBSTANCE: method of straightening flat products of carbon and alloyed steels involves compression of product between plates, heating it and soaking. Novelty is arrangement of flat plate on wheeled out hearth of furnace, placing one or more products onto it to be clamped from upwards by two or more plates having thickness 300-600 mm; wheeling hearth to furnace, heating products up to temperature equal to critical point Ac1 - 20 C, soaking at such temperature during 5-7 hours, air cooling up to 20 C. EFFECT: increased efficiency. 1 cl

Изобретение относится к области обработки металлов давлением, а именно к технологии машиностроения, и может быть использовано при правке плоских изделий из углеродистых и легированных сталей. Способ правки плоских изделий из углеродистых и легированных сталей, включающий сжатие изделия между плитами, нагрев и выдержку, новым в котором является то, что плоскую плиту устанавливают на выкатной под печи на нее укладывают одно или несколько изделий, которые сверху зажимают двумя или более плитами толщиной от 300 до 600 мм, затем закатывают под в печь изделия нагревают до температуры критической точки Аc1- 20oС, выдерживают при этой температуре 5-7 ч, а затем охлаждают на воздухе до комнатной температуры.The invention relates to the field of metal forming, in particular to mechanical engineering technology, and can be used for dressing flat products from carbon and alloy steels. A method of straightening flat products from carbon and alloy steels, including compressing the product between the plates, heating and holding, the new one being that the flat plate is mounted on a roll-out under the furnace one or more products are laid on it, which are clamped on top with two or more plates with a thickness from 300 to 600 mm, then rolled up under the oven products are heated to a temperature of a critical point A c1 - 20 o C, kept at this temperature for 5-7 hours, and then cooled in air to room temperature.
