Изобретение относитс  к Области листовой штамповки.The invention relates to the field of sheet stamping.

Известен способ изготовлени  изделий из сталей аустенитного класса путем выт жки из плоской заготовки полого издели  с глубоким охлаждением опасной зоны при помощи жидкого азота 1.A known method of manufacturing articles of austenitic steel by drawing from a flat billet a hollow article with deep cooling of the danger zone using liquid nitrogen 1.

Недостатком известного способа  вл етс  ограниченный коэффициент выт жки и недостаточное качество готового издели , так как при увеличении скорости выт жки металл в опасном сечении не успевает охладитьс  и происходит отрыв донной части полого издели .The disadvantage of this method is the limited draw ratio and the insufficient quality of the finished product, since with an increase in the draw rate, the metal in the dangerous section does not have time to cool down and the bottom part of the hollow product is peeled off.

С целью повышени  степени деформации и улучшени  качества готового издели  заготовку предварительно подвергают термообработке , после которой на заготовку нанос т защитное покрытие, а охлаждение опасной зоны заготовки осуществл ют до начала выт жки непосредственным воздействием жидкого азота на заготовку. Термообработку осуществл ют путем нагрева заготовки токами высокой частоты до температуры 1100- 1200°С и последующего охлаждени  в воде, а в качестве защитного покрыти  используют кремнеорганический грунт АГ ЮС с последующей сушкой, омыливанием и повторной сушкой .In order to increase the degree of deformation and improve the quality of the finished product, the billet is preliminarily heat treated, after which a protective coating is applied to the billet and cooling of the dangerous zone of the billet is performed prior to stretching by direct exposure of liquid nitrogen to the billet. Heat treatment is carried out by heating the billet with high-frequency currents to a temperature of 1100-1200 ° C and subsequent cooling in water, and the protective layer using AG JUS organosilicate primer followed by drying, saponification and re-drying.
