Description

(54) СПОСОБ ПРАВКИ СТАЛЕЙ МАРТЕНСИТНОГО КЛАССА(54) METHOD OF EDITING STEELS OF THE MARTENSITE CLASS

1one

Изобретение отиоситс  к способам правки сталей мартенситного класса, преимущественно листовых.The invention of Otosit to methods of editing steels of martensitic class, mainly sheet.

Известен способ правки сталей мартенси-гного класса, включаюпдий операции нагрева, охлаждени  и знакопеременного изгиба роликами .There is a known method of editing steels of the martensian class, including the operation of heating, cooling and alternating bending with rollers.

Дл  повышени  качества правки по предлагаемому способу изделие после нагревани  охлаждают до температуры, при которой образуетс  30% мартенсита, осуществл ют правку ,на правильной машине и охлаждают до окружающей температуры.In order to improve the quality of the straightening of the proposed method, the product is cooled after heating to a temperature at which 30% of martensite is formed, straightened, on a proper machine and cooled to ambient temperature.

Предложенный способ позвол ет значительно уменьшить неплоскостность листа, такThe proposed method can significantly reduce the flatness of the sheet, so

как в температурном интервале Мн-Мк сталь имеет хорошую способность к формообразованию .as in the temperature range of Mn-Mk steel has a good ability to shape.

Предмет изобретени Subject invention

Способ правки сталей мартенситного класса , преимущественно листовых, включающийThe method of editing steels of the martensitic class, mainly sheet, including

операции нагрева, охлаждени  и знакопеременного изгиба, отличающийс  тем, что, с целью повышени  качества правки, листы подвергают знакопеременному изгибу в интервале температур Мн - Мк при содержаНИИ мартенсита в стали не более 30%.heating, cooling and alternating bending operations, characterized in that, in order to improve the quality of the straightening, the sheets are subjected to alternating bending in the temperature range Mn-Mk with the content of martensite in steel no more than 30%.
