Distribution Control Devices

Overview

Distribution control devices, located beneath the spout and control pin, are custom-designed to distribute metal into vertical-direct chill (VDC) casting to maintain a stable casting process. A correctly designed distributor can minimize molten metal turbulence, retain oxide film, collect large particles, prevent scrapped slabs and improve the final metallurgical microstructure of the solidified VDC slab-rolling ingot slab. Since a distribution control device is one of the last components in the casting process to touch the molten metal prior to solidification, it is critical that only the highest quality products are used.
