Abstract: Изобретение относится к металлургии и машиностроению и может быть использовано для закалки изделий, выполненных из углеродистых и легированных сталей. Для повышения эффективности охлаждения и расширения диапазона закаливания металлических изделий  охлаждающую среду подают на заданном расстоянии от выхода закаливаемого изделия из деформирующих роликов под углом к поверхности с заданным расходом среды. Основное количество тепла отбирается на выходе изделия за счет предварительного нагрева и парообразования жидкости (воды), при этом используется водовоздушная среда с содержанием воздуха 10-20 %, которая подается на расстоянии 0,15-0,3 м от выхода закаляемого изделия из деформирующих роликов под углом к поверхности 10-15 градусов с расходом 250-330 см 3 /с среды и при начальной температуре (85-90)°С. Подача воды с регулированной воздушной фазой позволит создать условия охлаждения нужной интенсивности и скорости охлаждения, что значительно уменьшит расход охлаждающей среды и повысит полноту использования ее теплофизических свойств в процессе закалки. 1 ил.
