Abstract

Insbesondere auf dem Gebiet der Zerkleinerungstechnik werden Bauteile benötigt, in welchen die verschleißfeste, mit Hartstoffteilchen belegte Zone parallel zur Erstarrungsachse des herzustellenden Verbundkörpers verlaufen müßte. Especially in the field of Shredding technology, components are needed in which the wear-resistant, with hard material particles occupied zone parallel to the solidification axis of the manufactured composite body would have to run.

Zu diesem Zweck wird ein unter Anwendung des Elektroschlackeumschmelzens mit Hartstoffteilchen-­ Zugabe ablaufendes Herstellverfahren vorgeschlagen, bei dem in die Kokille (1) vor Beginn des Elektroschlackeumschmelzens ein fester metallischer Einsatzkörper (2) derart eingebracht wird, daß der den Restquerschnitt der Kokille ausfüllende Block (3) unter Bildung einer schlackefreien Verbundzone (4) mit dem Einsatzkörper einen Teil des Verbundkörpers darstellt. Die kontinuierlich zugegebenen Hartstoffteilchen (9) werden dabei in der Weise eingelagert, daß in dem Block (3) zumindest ein sich über seine gesamte Höhe in Kokillenlängsrichtung und zumindest über einen Teil seines Querschnitts erstreckender, hochverschleißbeständiger Bereich erzeugt wird. For this purpose, a using the Electroslag remelting with hard particles Adding manufacturing process proposed, where in the mold (1) before the start of the Electroslag remelting a solid metallic Insert body (2) is introduced such that the block filling the remaining cross section of the mold (3) forming a slag-free composite zone (4) with the insert part of the Composite body represents. The continuously added hard material particles (9) are in stored in such a way that in the block (3) at least one over its entire height in Longitudinal mold direction and at least over a part of its cross-section, highly wear-resistant area is generated.
