METHOD AND CASTING SYSTEM FOR THE DIRECTIONAL SOLIDIFICATION OF A CAST BODY MADE OF ALUMINUM OR AN ALUMINUM ALLOY

摘要

The invention relates to a method and to a casting system for the directional solidification of a cast body made of aluminum or an aluminum alloy. The problem of the invention is to create a technical solution in this respect, which enables a directional solidification for different cross-sections and high component complexity by lowering the casting mold into a cooling medium. Said problem is solved by a method and by a casting system, through the use of which the solidification can be controlled on the basis of the cast part geometry available as a CAD data record. Said data is used to electronically control the immersion speed of the lost cast nest into the cooling medium. In this way, the cast part structure can be optimized by the solidification speed of the melt.
