FIELD: foundry. SUBSTANCE: method involves positioning model with runner system into container; filling container with bulk ferromagnetic material; compacting by vibration; strengthening by periodically exposing to electromagnetic field with period of 3-5 sec. When electromagnetic field is induced, field induction is measured; in case predetermined value is obtained, vibratory compaction is stopped and electromagnetic field with permanent mode is induced. EFFECT: improved vibrational compaction process control, reduced ingot rejection by eliminating deformations or breakage of model.

Изобретение относится к литейному производству и может быть использовано при изготовлении литейных магнитных форм для получения отливок по газифицируемым моделям. Способ включает установку модели с литниковой системой в контейнер, заполнение его сыпучим ферромагнитным материалом, уплотнение его вибрацией и упрочнение электромагнитным полем поочередно с периодом 3 - 5 с. Во время включения электромагнитного поля в контейнере измеряется его индукция и при достижении заданного значения виброуплотнение прекращают, а электромагнитное поле включают на постоянный режим. Это позволяет управлять процессом виброуплотнения и снизить брак отливок за счет устранения деформации или поломки модели.The invention relates to foundry and can be used in the manufacture of foundry magnetic molds for producing castings for gasified models. The method includes installing a model with a gate system in a container, filling it with loose ferromagnetic material, compacting it with vibration and hardening with an electromagnetic field alternately with a period of 3-5 s. When the electromagnetic field is turned on in the container, its induction is measured, and when the set value is reached, the vibration seal is stopped, and the electromagnetic field is switched on for a constant mode. This allows you to control the process of vibration compaction and reduce casting rejects by eliminating deformation or breakage of the model.
