摘要： An apparatus for heating a flowable material comprises a core having a passageway formed therein for the communication of the flowable material, and an electric element coiled in multiple turns against the core in a helical pattern. The electric element, in use, heats the core both resistively and inductively. The electric element has no auxiliary cooling capacity. The electric element may be installed against the outside of the core, with an optional ferromagnetic yoke installed over it, or it may be installed against the inside of the core, embedded in a wear-resistant liner. The yoke and liner may be metallic material deposited such as by hot-spray technology and finished smooth.

摘要： A radial-flow, wide-pouring molten-metal distributor comprising a curved or arcuate overflow weir which is normally horizontal on its top and which is concave on its upstream side as viewed from above. Over this arc-shaped overflow weir flows molten metal to be continuously cast in an open pool. An impetus is thereby imparted to the molten metal along diverging radial lines. The flow so impelled continues radially onto a horizontal apron. The flow spreads fanwise to the desired width which may be as much as six times the width of the weir. Thence, the metal cascades or flows uniformly into the casting apparatus. The overflow weir is preferably supplemented by a skimmer mounted above it in substantially uniform spaced aligned relationship, thereby completing a slot beneath the skimmer through which the molten metal flows. When employed for the casting of wide, thin product, the invention results in a far more uniform and gentle distribution of metal than heretofore available. Dribbling and "beards" are eliminated. Swirls and porosity are reduced. The temperature profile across the section being cast is rendered more uniform, thereby permitting a lower temperature of the supply of molten metal entering this novel distributor.

摘要： Non-rotating, belt-levitating, cylindrical air-pillow method supporting and guiding a moving, tensed, flexible, heat-conductive casting belt along a convex, cylindrically shaped path toward an entrance into a continuous casting machine. Pressurized air is applied in belt-levitating relation to the inner surface of the casting belt moving along the path. Stationary belt-guiding elements define the path. Pressurized air is fed through throttling passages communicating with regions between stationary elements or communicating with outwardly facing stationary plateau surfaces. For reducing flexural stress in the belt moving toward the entrance, a variable radius R+ progressively increases toward the entrance. Escape of pressurized air is restricted by throttling barrier on a perimeter of the belt path. A cylindrical shell supports the stationary elements and is adjacent to a plenum chamber feeding pressurized air through throttling passages in the shell.

摘要： 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 front surface by heat from molten metal while being cooled at its reverse surface by flowing liquid coolant. Each finned backup roller includes an elongated, non-magnetic shaft rotatable around its axis and having multiple annular fins of magnetically soft ferromagnetic material fitted onto the shaft spaced along the shaft. The fins have circular perimeter rims for rolling contact with the reverse surface of a belt. Intervening collar shaped reach-out permanent magnets 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. Thus, fins become magnetized by the magnets with their perimeters having alternate North and South magnetic polarities in sequence along the roller. In addition to attraction of the belt by magnetic flux which passes through small localized rim-contact regions where fin rims are rolling on the belt surface, the belt also is attracted toward the fins by reach-out magnetic flux extending out in three-dimensional patterns toward the belt from the rim and also from tapered side surfaces of each fin.

摘要： A magnetic induction pump for pumping molten metal. The pump includes a motor and a shaft operatively connected to the motor. The pump further includes at least one bipolar permanent magnet operatively connected to the shaft and a conduit for the passage of molten metal. The motor rotates the shaft and magnet about the conduit inducing eddy currents in the molten metal in the conduit which react with the moving magnetic field to produce force to pump the metal through the conduit with the metal coming into contact with only an interior surface of the conduit.

摘要： Apparatus, system and method precisely, quickly control flow of molten metal to metal-casting apparatus by pumping, braking or throttling. The Faraday-Ampère principle of current flow in a unidirectional magnetic field is employed. Permanent magnets comprising neodymium or similar high-energy, rare-earth materials provide “reach-out” magnetism. These neo-magnets, usually shown as cubes, are arranged in various powerful configurations driving intense unidirectional magnetic field B across a non-magnetic gap many times larger than economically feasible otherwise. This gap accommodates a conduit for pressurizing and moving a flow of molten metal. In making multiple identical castings, a controlled, intermittent, predetermined flow of molten metal is fed to a series of identical individual molds. The invention obviates needs for operating metallurgical valves or expensive tilting mechanisms for metallurgical furnaces. Existing furnaces too low to permit inflow by gravity may be rendered usable by embodiments of this invention.

摘要： Permanent-magnetic hydrodynamic methods and apparatus stabilize a moving, flexible, thin-gauge, heat-conducting, magnetically soft ferromagnetic casting belt against thermal distortion while moving along a mold cavity being heated at its front surface by heat coming from molten metal being cast while being cooled at its reverse surface by flowing pumped liquid coolant. Hydro-magnetic devices are arranged in an array wherein flows of pumped coolant pass through fixedly throttling passageways feeding pressure pockets facing the belt's reverse surface. These pockets are shown rimmed by magnetic pole faces. Coolant issues from the pressure pockets as fast-moving films radiating therefrom and travelling in gaps between the belt's reverse surface and the pole faces. These films cool the belt and apply hydrodynamic forces levitating the belt spaced from the pole faces while the belt is stabilized in even condition by powerful reach-out magnetic attraction forces reaching out from these pole faces and extending across the gaps to the moving belt. Pumped liquid coolant is twice throttled: once in feeding into the pressure pockets and once again in flowing out from the pockets escaping over the pole faces which rim the pockets. A hydro-magnetic array includes powerful permanent magnets formed of unique permanent-magnetic material in magnetic circuits in the array providing reach-out magnetic attraction having unusual characteristics critical to successful operation of disclosed embodiments of the invention. A hydro-pillow array without magnets may be positioned downstream from the hydro-magnetic array.
