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.

Abstract: A method and system is used for achieving increased precision of steering of the flexible, metallic endless belts (12) of continuous metal-casting machines (9). Such belts (12) usually have the imperfections that are more or less inherent in the parent strip metal from which the belt is made. For example, in low-carbon steel belts, there is generally a ''camber'', a curvature of the edges in the plane of the strip material. Belts, revolving in the machine, are normally steered through sensing the lateral or side-to-side position of one edge. If the edge is not true, due to camber, the servo steering system of the prior art will continually ''hunt'' caused by variations in lateral position of the cambered edge. The present invention provides a steering method and system responsive to a single signal (18), fixed on a belt edge. This single signal source (18) can be achieved by notching or otherwise cueing a belt at one place along an edge so that the steering sensor (20) senses this cue notch as the belt is revolving. A first electrical circuit is arranged to sense this cue notch (18) and to activate or initiate, i.e. cues the commencement of a sensing control operation. The sensing control operation, in response to sensing of the tracking error of a predetermined control place or region on the belt following the ''cue'', then governs the steering mechanism and thereby eliminates or substantially reduces the prior-art continual ''hunting'' steering problems in twin-belt metal casting machines.

Abstract: Elongated finned backup rollers have multiple magnetized fins for rolling contact with a moving endless, flexible, thin-gauge, heat-conducting, magnetically soft ferromagnetic casting belt for guiding and stabilizing the belt against thermal distortion while it moves along the mold cavity being heated at its reverse surface by flowing liquid coolant. Each finned backup roller includes an elongated, non-magnetic shaft (10) rotatable around its axis (22) and having multiple annular fins (26) of magnetically soft ferromagnetic material fitted onto the shaft spaced along the shaft. The fins have circular perimeter rims (28) for rolling contact with the reverse surface (34) of a belt (40). Intervening collar-shaped reach-out permanent magnets (30) are mounted on the shaft between successive fins. The fins and reach-out collar magnets alternate in sequence along the length of the roller. The reach-out collar magnets are magnetized in a direction parallel with the axis of the roller.
