1. 1. Problems in the Aluminium DC Casting Process Associated with Melt Treatment Operations

   Författare :Ghadir Razaz; Torbjörn Carlberg; Arne.K Dahle; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The quality of DC cast Al alloys is highly dependent on melt batch composition and impurity level in the molten alloy. The chemical composition and cleanliness of a melt is controlled through the melt treatment operations, carried out while the melt is still in the furnace before casting starts. LÄS MER
