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 pre-determined 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.
