Abstract: The invention relates to a sequence casting process for producing a high-purity cast metal strand from a metal melt, the metal melt being fed in controlled fashion from a metal vessel to a tundish and being discharged in controlled fashion from this tundish into a continuous-casting mold, and the supply of the metal melt into the continuous-casting mold being continued without interruption. To allow a high-quality metal strand to be cast even during the change of melt vessel in this process, with the restart phase being kept as short as possible, it is proposed that during a period of time from the resumption of the supply of metal melt into the tundish until the point at which a quasi-steady operating bath level in the tundish is reached, the inflow rate into the tundish is greater than the outflow rate out of the tundish, and for 70% to 100% of this period the inflow rate into the tundish is less than or equal to double the outflow rate out of the tundish.

Abstract: A continuous casting method includes the steps of continuously supplying molten metal into a mold through at least one feed nozzle connected to the mold through a break ring, with the feed nozzle, the mold and the break ring forming at least a portion of a continuous casting apparatus, and intermittently withdrawing a cast piece formed from the molten metal in the mold thereby creating pressure in a space formed at a connecting point between the break ring, the mold and the cast piece as a result of the withdrawal from the mold. A shield means is placed to seal-off space between the at least one feed nozzle, and the mold to prevent entry of gas into the continuous casting apparatus and the pressure is reduced in the sealed-off space to thereby eliminate a pressure differential between the pressure in the sealed-off space and the pressure created in the space formed at the connecting point between the break ring, the mold and the cast piece during the intermittent withdrawal from the mold.

Abstract: An improvement in systems for continuous casting steel to near net shape sheet or plate directly from molten metal. This is accomplished by floating the liquid steel on a liquid substrate of silver, allowing it to solidify and withdrawing a continuous section of thin, wide steel. Liquid to liquid casting, by eliminating the mechanical problems of thin sheet casting with wheels or belts, allows for increased tonnage rates. For example, aiming at a thickness of 3 mm. by a width of 1500 mm., a liquid steel to liquid silver caster in continuous production at 200 feet per minute will produce 750,000 tons per annum. Increased cast speeds and/or multiple lines due to simple construction seem practicable for greater tonnage. Only liquid silver, as a float medium, makes high quality float casting of molten steel possible.

Abstract: The invention discloses a method and apparatus for horizontal continuous casting of thin steel slabs by floating liquid steel on the surface of a pool of molten lead and allowing the steel to solidify by cooling to form a continuous flat ribbon. The virtually complete immiscibility between iron and lead is the key to the invention and also the fact that iron floats on lead, both are good heat conductors and molten lead is non-wetting towards solid iron and a good lubricant for it. The method is conducted in an elongated tray containing a molten lead pool and incorporating lateral edge dams defining the cast slab width. Liquid steel from a prior process is continually introduced from a tundish or ladle and distributed uniformly across the entry end while avoiding turbulence and mechanical mixing between lead and steel. Heat is extracted by external cooling as the steel progresses along the tray, causing it to freeze and form an outer shell solidification front extending transversely between the edge dams.

Abstract: Thin metal sheets are cast by magnetically suspending molten metal deposited within a ferromagnetic yoke and between AC conducting coils and linearly displacing the magnetically levitated liquid metal while it is being cooled to form a solid metal sheet. Magnetic flux increases as the molten metal sheet moves downward and decreases as the molten metal sheet moves upward to stabilize the sheet and maintain it in equilibrium as it is linearly displaced and solidified by cooling gases. A conducting shield is electrically coupled to the molten metal sheet by means of either metal sheet engaging rollers or brushes on the solidified metal, and by means of an electrode in the vessel containing the molten metal thereby providing a return path for the eddy currents induced in the metal sheet by the AC coil generated magnetic flux.

Applying jerks to the casting chamber by varying the driving speed of the endless belt ensures that the solidifying metal will travel smoothly and thus ensures a high manufacturing yield.

Abstract: In horizontal continuous casting, the casting proceeds step-by-step with the forming strand being intermittently pulled from the mold.

This forms a thin wall in the skin at that location, forming a breaking location or point where the skin pulls apart each time the strand is pulled forwardly. The mold is continuously fed with melt and the skin's strand reforms or welds together at the strand break.
