High turbulence roll cooling
WebJun 27, 2024 · Each process has to be treated a little differently, but with the same goal—to achieve turbulence at the heat-exchange surface to maximize heat transfer. For example, in a chill roll for sheet/cast film, cooling turbulence is created in the spiral wraps to cool the shell. For blow molds, turbulence is generated in the water passages of the mold. WebImplementation of a position controlled HTRC system provided effective roll cooling using a low pressure water supply (3-4 bars), without compromising roll and strip surface quality.
