Abstract
Permanent-magnetic hydrodynamic methods and apparatus stabilize a moving, flexible, thin-gauge, heat-conducting, magnetically soft ferromagnetic casting belt (50) against thermal distortion while moving along a mold cavity (C) being heated at its front surface by heat coming from molten metal being cast while being cooled at its reversed surfaces by flowing pumped liquid coolant. Hydro-magnetic devices (38) are arranged in an array (51) wherein flows of pumped coolant (93) pass through fixedly throttling passageways (90) feeding pressure pockets facing the belt's reverse surface. These pockets are shown rimmed by magnetic pole faces (34). Coolant issues from the pressure pockets as fast-moving films to cool the belt's reverse surface and levitate the belt spaced from the pole faces while the belt is stabilized in even condition by powerful reach-out magnetic attraction forces.
