A method for grain refinement of metallic casting substances, as well as a casting tool made of such a gefeinten metallic casting material

摘要

in the process for kornfeinen metallic casting materials, particularly aluminum, copper, nickel, cobalt, iron and / or alloys of these materials, the feinende guu00dfwerkstoff to melt heats and the kornfeinungsmittel upon heating to a temperatu r, is greater than the temperature of the melts of the guu00dfwerkstoffs, admittedly.so there is a deterrence of kornfeinungsmittels in bringing into the melt of the feinenden material. this promotes the grain refinement and leads to the kornfeinungsmittel after solidification of the werkstoffschmelze keimwirksame formations and / or particulate matter in the diameter in the area around 1 m and 0.5 m).
