Abstract:

A casting apparatus () for direct chill casting metal includes a tundish () containing a supply of molten metal, a casting mold (), and a starter block () associated with the casting mold (). The casting mold () is in fluid communication with the tundish () through a passage () defined in the tundish wall. The casting mold () includes a header plate (), a casting ring (), and a feed ring (). The header plate () defines an arcuate shaped opening () connected to the passage (). The header plate () has an upstream side () and a downstream side (). The casting ring () is connected to the downstream side () of the header plate () and defines a groove () proximate to the sidewall () of the header plate (). The feed ring () is disposed in the groove.
