Description

Изобретение относитс  к области спец- электрометаллургии, в частности к попучени фасонных отливок с приплавл емыми элементами из проката, пить , поковок, методом электрошпаковой выплавки (ЭШВ).The invention relates to the field of special electrometallurgy, in particular, to the distribution of shaped castings with melted elements from rolled metal, for drinking, forgings, by the method of electrospark smelting (ESM).

Известные способы получени  фасонных Отливок методом ЭШВ, заключающиес  в переплаве расходуемых электродов в охлаждаемом кpиcl aлпизaтope с приплавлением фасонных элементов, имеют cymecTBeH ные недосд-атки, основным из которых  вл етс  отсутствие стабильности качества приппавлени  элемента к телу отливки по наружному контуру в зоне приппавленуш.Known methods for producing shaped castings using the ESW method, which consist in remelting consumable electrodes in a cooled crystalline alloy with melting of shaped elements, have cymecTBEH shortcomings, the main of which is the lack of stability of the quality of the element being bonded to the body of the casting through the external contour in the zone in the zone in the area of the surface of the surface in the zone.

Как показали исследовани  процессаAs shown by research process

приплавлени , при диаметре pacxoayeN oro электрода, большем или равном диаметру эпёмента, капельный перенос металла рас- ходуемого электрода происходит таким обра зом, что капли переплавл емого металла попадают на уже оплавленную поверхность приплавл емого элемента, образу обшую металлическую ванну по контуру элемента. Важное значение имеет также приплавление приплавл емого элемента. Оптимальные When the diameter of the electrode is larger than or equal to the diameter of the electrode, the drop transfer of the metal of the consumed electrode occurs so that the melted metal drops fall on the already melted surface of the element being melted, forming a common metal bath along the contour of the element. Also important is the melting of the melted element. Optimal

услови  дл  этого создаютс  при определенной величине заглублени  элемента в шлаковую ванну.The conditions for this are created at a certain amount of penetration of the element into the slag bath.

Предложенный способ заключаетс  в том, что прмппавл емый элемент в начальный период ведени  процесса заглубл ют в шлаковую BaHiiy на ве)1ичи51у 0,2-О,6 ее глубины , а процесс выплавки ведут расходуемым электродом, диаметр которого не менее диаметра приплавл емого элемента.The proposed method consists in the fact that in the initial period of the process, the imprinted element is buried in the BaHiiy slag at a depth of 0.25 Å and 6 times its depth, and the smelting process is carried out with a consumable electrode whose diameter is not less than that of the element being melted.

Такое ведение процесса выплавки обеспечивает равномерное оплавление заглубл емого в шлаковую ванну торца элемента и гарантированное приплавление его по контуру и сечению-К телу отливки.Such a process of smelting ensures the uniform melting of the end of the element that is buried in the slag bath and the guaranteed fusion of it along the contour and section-K of the casting body.

Этот способ целесообразно использовать при выплавке фасонных отливок с приплавл емыми элементами, например: крышек корпусов энергоарматуры, тройников, запорной арматуры, прокатных валков, крупных валов различных двигателей и jenepaTQpOB и т. д.This method is advisable to use in the smelting of shaped castings with fused elements, for example: covers of power armature housings, tees, valves, rolls, large shafts of various engines and jenepaTQpOB, etc.
