摘要： A monitoring system may monitor a casting environment, for example, including a mold. The monitoring system may include a camera and a computer system. The camera may be positioned to capture or detect optical data associated with one or more components in a casting environment. The camera may send the optical data to the computer system and the computer system may generate a profile associated with the casting environment. The profile may be compared with a baseline profile to determine whether a particular event has occurred. Based on the event that may have occurred, operating instructions can be generated. The operating instructions may be used to adjust the casting process.

摘要： A method for the continuous casting of a metal strand in a continuous casting installation, in which, in a casting machine, the metal formed into a slab, with a still molten core, is brought out vertically from a mold, wherein, downstream of the mold in the conveying direction, the slab is made to move along a casting bow, through a number of casting bow segments, and is deflected into the horizontal, wherein each casting bow segment has a number of segment rollers, which are designed for coming into contact with the surface of the slab. In the region before the end of the casting machine, a number of segment rollers are lifted off from the surface of the slab, or are not installed in receptacles provided, and so the contact between the slab and the segment roller is interrupted or there is no contact.

摘要： Method for producing ingots made of metal having cross-sectional areas of at least 0.10 m2 of a round, square or rectangular shape through casting of metal or molten steel either directly from the casting ladle (1) or using a fireproof lined intermediate vessel (3) in a short, water-cooled ingot mold open downwards (4) and withdrawing of the solidified ingot (6) from the same downwardly movable withdrawing tool (8), wherein the casting process is continued with a casting rate determined in accordance with the casting cross-section for as long as the desired or maximum ingot length determined by the height of lift of the withdrawing tool (8) is reached, and additional liquid metal is fed at the end of the regular casting process to an extent that at least the contraction of the metal and steel melt occurring during solidification is balanced during, and whereby after completion of the regular casting process and completion of the ingot withdrawal, the casting process is continued with a casting rate reduced by at least the Factor 10 from the heatable casting ladle (1) or the heatable intermediate vessel (3) or a distribution container, and is reduced progressively or continuously at the end of the solidification to 10% the rate at the start of the additional casting.

摘要： A system and method for continuous casting. The system includes a melt chamber, a withdrawal chamber, and a secondary chamber therebetween. The melt chamber can maintain a melting pressure and the withdrawal chamber can attain atmospheric pressure. The secondary chamber can include regions that can be adjusted to different pressures. During continuous casting operations, the first region adjacent to the melt chamber can be adjusted to a pressure that is at least slightly greater than the melting pressure; the pressure in subsequent regions can be sequentially decreased and then sequentially increased. The pressure in the final region can be at least slightly greater than atmospheric pressure. The differential pressures can form a dynamic airlock between the melt chamber and the withdrawal chamber, which can prevent infiltration of the melt chamber by non-inert gas in the atmosphere, and thus can prevent contamination of reactive materials in the melt chamber.

摘要： In melting and casting by a water-cooled crucible induction melting technique, a partition means is inserted on top portion of a melt, and a new raw material for is charged on an upper side of the partition means to continue the melting and casting. Therefore, the continuous casting can be kept while avoiding mixture of the melt on a lower side of with the melt on an upper side of the partition means. A partition plate or a partition plate with legs can be used as the partition means. When the present invention is applied to production of a silicon ingot used for a solar cell and the like, productivity is largely improved, which allows costs to be remarkably reduced in solar energy generation. Therefore, the present invention can widely be utilized as the method for casting a polycrystalline-silicon ingot for a solar cell.

摘要： The melting rate of pre-alloyed consumable electrodes, melted in a controlled atmosphere, is selected and controlled to provide a desired freezing rate of a solidified billet delivered from a continuous casting machine. By controlling the power input to the electrode, the volume and temperature of metal melted and poured into the casting mold is also controlled to achieve a desired freezing rate and grain structure in the resulting ingot.
