Description

Изобретение относитс  к металлургической промышленности, в частности к способам лить , например, металлов в посто нные формы .The invention relates to the metallurgical industry, in particular to methods for casting, for example, metals in permanent forms.

Известен способ определени  готовности слитков к освобождению от изложницы, включающий заливку расплава и его выдержку до образовани  на слитках твердой корки, сн тие и охлаждение слитков с выбранной скоростью с помощью охладителей.There is a known method for determining the readiness of ingots for release from the mold, which includes pouring the melt and holding it until a solid crust forms on the ingots, removing and cooling the ingots at a selected rate using coolers.

Недостатком известного способа  вл етс  то, что пр мое дистанционное определение момента образовани  на слитке твердой корки технически сложно и св зано с возможностью ошибок (преждевременное раздевание слитка ) и аварийных ситуаций.The disadvantage of the known method is that direct remote determination of the moment of formation of a hard crust on an ingot is technically difficult and is associated with the possibility of errors (premature stripping of the ingot) and emergency situations.

Цель изобретени  - улучшение качества получаемого слитка.The purpose of the invention is to improve the quality of the ingot produced.

Дл  этого по предлагаемому способу после заливки расплава в изложницу определ ют, например, дефектоскопией момент образовани  (устойчивого) зазора между боковыми поверхност ми слитка и стенками изложницы, после чего слиток освобождают от изложницы .For this, according to the proposed method, after pouring the melt into the mold, for example, by means of a flaw detection, the moment of formation of a (stable) gap between the side surfaces of the ingot and the walls of the mold is determined, after which the ingot is freed from the mold.

Возможность и целесообразность такого способа лить  обосновываетс  тем, что образование устойчивого зазора между слитком и стенками изложницы свидетельствует о способности слитка в данный момент самосто тельно сохран ть свою форму, а после освобождени  его от литейной формы процесс дальнейшего охлаждени  и твердени  пойдет за счет излучени  в окружающую среду. Изложница после образовани  зазора мешает управлению процессом охлаждени  слитка.The possibility and feasibility of this method of casting is justified by the fact that the formation of a stable gap between the ingot and the walls of the mold indicates the ability of the ingot at the moment to maintain its shape independently, and after freeing it from the mold, the process of further cooling and hardening will be due to radiation into the surrounding Wednesday The mold after the formation of the gap interferes with the control of the cooling process of the ingot.

При раннем освобождении слитка от изложницы создаетс  возможность регулировать процесс охлаждени  так, чтобы обеспечить наилучшее качество слитка.With early release of the ingot from the mold, it is possible to regulate the cooling process so as to ensure the best quality of the ingot.
