Abstract
An arrangement for the manufacture of solid forging blocks with manipulator pins in which an electro-slag remelt process is used for filling an ingot having a vertical bore hole. At least one consumable electrode is used, and the ingot with the vertical bore is placed on a block table having at least one power connection in the region of the block table and flush with a depression for slag start material. The filling of the core zone is started with this depression having a depth of substantially at least 25% of the diameter of the block bore. A movable starting disk is applied as a lower boundary of the depression, and the slag start material is placed on top of the disk. After formation of liquid slag, the depression is exclusively filled from material of the consumable electrode. The power connection to the starting disk is fed along during the entire remelt process.
