Description
Изобретение относитс к технолоии очистки поверхности метагшичес- 5х изделий и может быть применено ри производстве, обработке,восстаовлении или ремонте деталей машин, которым предъ вл ютс повышенные Требовани по качеству поверхности, чистоте, структуре и свойствам поверхностного микросло без изменени свойств всей массы металлических изделий,что особенно важно при производстве деталей,предназначенных дл работы в реакторах}например атомных химических и др,The invention relates to the technology of cleaning the surface of metal products and can be used in the manufacture, processing, repair or repair of machine parts that are subject to increased requirements for surface quality, purity, structure and properties of the surface micro-layer without changing the properties of the entire mass of metal products, which is especially important in the manufacture of parts intended for operation in reactors} such as atomic chemicals, etc.
Цель-изобретени - повышение качества и ЭКОНОШ1ЧНОСТИ процесса очистки, .The purpose of the invention is to improve the quality and COST of the cleaning process,.
Способ осуществл ют слсдую щим образом. The method is carried out sequentially.
После расплавлени окислов,име- юш,их .большее средство .к кислороду ; чем металл очищаемой детали,деталь окунают в расплав и выдерживают в нем необходимое врем , при этом деталь может перемещатьс в расплаве дл интенсификации процесса,что снижает глубину ее прогревани .After the oxides have melted, having their own, their most important means of oxygen; than the metal of the part being cleaned, the part is immersed into the melt and the necessary time is kept there, while the part can be moved in the melt to intensify the process, which reduces the depth of its heating.
В.качестве окислов дл очистки стальных деталей может быть применен- эпектрошлак ,в частности один из наиболее доступных составов-из 45% СаО и 55% AljOj, нагретый до 950- 1200°С.C. Electro-slag can be used as oxides for cleaning steel parts, in particular, one of the most accessible compounds — from 45% CaO and 55% AljOj, heated to 950– 1200 ° C.
Окислы в расплавленном пиде вл ютс раскислител ми,восстанавлива окисленные поверхности детали. КроРедактор А.Вер Заказ 2565The oxides in the molten material are deoxidizing agents by reducing the oxidized surfaces of the part. Cro Editor A.Ver Order 2565

ме того, при столь высокой температуре осуществл етс выжигание загр з нений, наход щихс на поверхности детали.Продукты взаимодействи расплава окислов с загр знени ми на поверхности детали поглощаютс расплавом. Возможность минимального воздействи на очищаемую поверхность детали по времени и глубине и повьшенна коррозионно-механическа прочность поверхности в результате такой обработки позвол ет признать спос об полезным.moreover, at such a high temperature, the burning of soils on the surface of the part is carried out. The products of the interaction of the melt of oxides with the soils on the surface of the part are absorbed by the melt. The possibility of a minimal impact on the surface being cleaned over the part in time and depth and the increased corrosion-mechanical strength of the surface as a result of such treatment allows one to recognize the method useful.
