Изобретение относитс  к технологии литейного нроизводства.This invention relates to foundry technology.

Известен спосО:б охлаждени  отлйвок в литейной форме лутем лодачи охлаждающего агента iK поверхности раздела фор.ма-отливка после образовани  закристаллизовавшейс  корки отлив«и.The known method is: b cooling of castings in the casting mold with lutem of cooling agent iK of the interface of the form-molding section after the formation of a crystallized peel casting and.

Дл  улучшени  качества отливки предлагаетс  способ, по которому охлаждающий агент подают в импульсном режиме.To improve the quality of the casting, a method is proposed by which a cooling agent is pulsed.

Способ реализуют следующем образом.The method is implemented as follows.

Заливают форму металлом с температурой, превышающей темлер атуру ликвидуса.Fill the form with metal with a temperature exceeding the temler atura of the liquidus.

Поверхность раздела о-тливка--форма -при темпратуре, превышающей температуру солидуса , подвергают импульсному воздействию воды с частотой 2-5 имп/мин.The surface of the section of the mold - form - at a temperature above the solidus temperature, is subjected to a pulse of water with a frequency of 2-5 pulses / min.

.При этом ускор етс  процесс теплоотвода металла отливки за счет увеличени  охлалСдающей способности формы « увеличиваетс At the same time, the process of heat removal of the metal of the casting is accelerated by increasing the cooling capacity of the mold "increases

скорость кристаллизации по всему сечению отл«в:ки.crystallization rate over the entire cross section is ex.

Импульсна  лодача воды нес.бходи-ма дл  того, чтобы удалить пары пслар ющейс  воды и не создавать опасности образовани  газовых раковин в отлив-ке.Pulsed water stripping is carried out in order to remove the fused water vapors and not create the danger of gas pockets forming in the casting.

Дл  равномерности охлаждени  и уменьшени  остаточных напр жений к поверхности раздела отливка-форма подают воду в количестве, пропорциональном толщине соответствующих элементов отливки.For uniformity of cooling and reduction of residual stresses to the interface of the casting-form, water is supplied in an amount proportional to the thickness of the respective casting elements.

Предмет изобретени Subject invention

Способ охлаждени  отливок е литейной форме, ВКлючающий подачу охлаледающего агента к поверхности раздела форма-отливка носле образовани  закристалл113овав(шейс  корки отливки, отличающийс  тем, что, с целью улучшени  качества отливки, охлаждающий агент подают в импульсном режиме.A method for cooling castings in a casting mold, which turns on the supply of a cooling agent to the surface of the mold, during which it forms a crystallized form (casting crust, characterized in that in order to improve the quality of the casting, the cooling agent is pulsed.
