Description
tt
Изобретение относитс к электро .металлургии, в частности к электрошлаковому переплаву.The invention relates to electrometallurgy, in particular to electroslag remelting.
Известен разъемный охлаждаекий дорн, в котором между его водоохлаждаемыми элементами установлены неметсшлические вставки изготовленные из материалов, нераствор е ых шлаком - графита или карбонитрида бора.Known split cooling mandrel, in which between its water-cooled elements are installed non-metallic inserts made of materials, insoluble slag - graphite or boron carbonitride.
После выплавки слитка необходимо удалить графитовые вставки механическим путем дл получени полой заготовки, а этот процесс очень трудоемок.After the ingot is melted, it is necessary to remove the graphite inserts mechanically in order to obtain a hollow billet, and this process is very laborious.
С целью обеспечени удалени дорна в предложенном дорне между Сопр гаекыми плоскост ми, элементами дорна, установлены одна или более металлические вставки из материала с температурой плавлени ниже температуры плавлени слитка и дорна,причем вставка выполнена охлаждаемой. На чертеже показан предложенный дорн.In order to ensure that the mandrel is removed, in the proposed mandrel between the Contact planes, the mandrel elements, one or more metal inserts of material with a melting point below the melting point of the ingot and mandrel are installed, the insert being made to be cooled. The drawing shows the proposed mandrel.
В дорне между его водоохлаждаемыми элементами 1 устанавливаютс легкоплавкие охлаждает ие или неохлаждаекые водой вставки 2 из металла, .например алюмини , температура плавлени которого:ниже температуры плавлени выплавл емого слитка и дорна .In the mandrel, between its water-cooled elements 1, low-melting fusible coils are installed or water-cooled metal inserts 2, such as aluminum, the melting point of which is lower than the melting point of the melted ingot and mandrel.
Такие вставки предназначены дл одноразового использовани и после затвердевани слитка легко могут быть удалены посредством coBNrecTHoro нагрева слитка с дорном и всггавками до температуры выие температуры плавлени вставок, что обеспечивает свободное извлечение полого слитка. Such inserts are designed for one-time use and after the ingot is solidified, they can easily be removed by coBNrecTHoro heating the ingot with mandrel and up to a temperature of the melting point of the inserts, which ensures free removal of the hollow ingot.
