Abstract (en)
[origin: ES8502891A1] Liquid metal M in a casting ladle 1 located under a mold A is cast uphill under low pressure into the mold cavity 10 through a vertical shaft 3. The metal is treated by a soluble inoculation wire 13 suspended down through the cavity over a length L greater than the height h of the mold with its lower part H submerged in the liquid metal filling the shaft. The ladle pressure is maintained until the wire is fully dissolved, and then raised to fill the mold cavity with the inoculated liquid metal.
