System for removing non-metallic foreign matter in molten metal

One or more streams of molten metal poured into a continuous casting mold are acted on magnetically by static magnetic fields, covering substantially the entire width of the casting mold, thereby reducing the speed of the molten metal streams from the immersion nozzle, unifying the flow profile of the molten metal in the mold, preventing trapping and accumulating of mold powders and inclusions into the cast products. Magnetic poles are provided which are at least as wide as or wider than the minimum width of the cast products and the iron core is arranged on the same face of the casting mold with mutually opposite polarities in the drawing direction. Even if casting conditions change from time to time, defects in final products made of the cast metal are substantially reduced.

Apparatus and method for continuous casting

In order to securely hold a moving belt of a continuous casting device against selective movable side walls, a first group of rotatable control rods which are disposed in a first supply header and an adjacent exhaust header are arranged to produce narrow high pressure zones in the film defined between the cooling pad in which the header are formed and the moving belt. These zones can be selectively moved to juxtapose the side walls when the gap between the walls is adjusted. A second group of rotatable control rods which are disposed in second and third supply headers selectively heat the side edges of the belt which are relatively cool as compared with the center section which is exposed to molten metal. As the side walls are moved apart the width of the edge sections which are exposed to pre-heated coolant can be reduced and the amount of normal temperature coolant applied thereto also increased.

Cooling pad arrangement for belt caster type continuous casting device

A belt type cast sheet continuous caster of the type comprises a pair of opposed circulatorily movable belts, a pair of opposed side plates arranged along opposite side edge portions of the movable belts, coolers which each have numerous water feed openings and water discharge openings opened to the movable belt and are arranged behind the respective movable belts, and movable partition plates which are placed in respective cooling headers and each connected to driving means for moving the partition plates in a width direction of a cast sheet. A casting space is defined by the movable belt and the side plates. Melt leakage at sliding portions between mold short side plates and the metal belts in a belt type cast sheet continuous caster comprising the metal belts and the mold short side plates arranged along side edge portions of the metal belts and cooleres, which each have numerous water fed openings and water discharge openings opened to the metal belt and are arranged behind the respective metal belts, is prevented by controlling gaps between the metal belts and the mold short side plates through varying a pushing force of the metal belts to the mold short side plates.

Belt type cast sheet continuous caster and prevention of melt leakage in

A continuous casting apparatus for the production of cast sheets having a casting space defined by a pair of opposed endless belts and a pair of side plates arranged near the side edge portions of the belts while being brought into intimate contact therewith and designed to be converged toward a drawing direction. In this apparatus, a filmy water flow-forming pad arranged behind each of the belts, and each of the side plates are so profiled that the casting space inclusive of the tapered portion depicts a smooth curve at at least a transition area from the taper end portion to a constant thickness portion.
