Abstract
Disclosed is a system for providing consistent lubricant and/or gas flow through multiple permeable perimeter walls in a casting mold table. One or more of the properties of the perimeter walls indicative of the lubricant flow or gas flow rates through the perimeter walls are predetermined and the sizing of the surface area of the delivery conduits providing the lubricant or the gas are determined based on a correlation to the properties related to the measured or estimated lubricant flow rate and/or measured or estimated gas flow rates through the perimeter walls.
