Managing Grain Refining Efficiency: The Way Forward for Aluminum Casthouses

摘要

Grain refiners are sold to casthouses and foundries with one purpose-to create a fine-grained structure in the cast aluminum. Or that's what they should do. In principle, all aluminum melts must be grain refined to avoid cracks in the cast product. This is achieved by adding grain refiners that contain particles that act as substrates for aluminum grains when the liquid metal is solidifying.
