摘要： Apparatus and methods for consolidating granular silicon and determining trace elements content of the consolidated silicon are disclosed. Silicon granules are placed in a vessel, and a silicon slug of known purity is embedded at least partially in the granules. The slug is preheated to a temperature sufficient to couple with an induction heater. As the silicon slug melts, silicon granules adjacent the molten silicon also melt. The vessel passes through an induction coil to successively inductively heat and melt regions of the silicon granules from the leading end to the trailing end with each region solidifying as the molten silicon exits the induction coil to provide a multicrystalline silicon ingot. The multicrystalline silicon ingot is sliced into wafers, which are analyzed by low-temperature Fourier transform infrared spectroscopy to determine levels of trace elements in the ingot.

摘要： An exemplary embodiment provides a method of fully or partially eliminating a shrinkage cavity in a metal ingot cast by direct chill casting. The method involves casting a metal ingot by introducing molten metal into a direct chill casting mold from a spout to form an upright ingot having an upper surface at a predetermined height. Upon completion of the casting, the lower tip of the spout is preferably maintained below the upper surface in molten metal at or near a center of the upper surface of the ingot. The metal flow through the spout is terminated while maintaining sufficient heat in metal within and supplying the spout to keep the metal molten for subsequent delivery through the spout. A partial shrinkage cavity is allowed to form in the upper surface of the ingot as metal of the ingot shrinks and contracts. Preferably before the partial cavity exposes the lower tip of the spout, the partial shrinkage cavity is preferably over‐filled with molten metal, while all or significant spillage of molten metal from the partial cavity is avoided, and then the flow of metal through the spout is terminated. The steps of allowing a partial shrinkage cavity to form in the upper surface and then preferably over‐filling the partial shrinkage cavity with molten metal from the spout before the cavity exposes the lower tip is repeated, preferably until no further contraction of the metal of the ingot causes any part of the upper surface to contract below the predetermined height. The spout is then removed from contact with molten metal of the ingot and all parts of the ingot are allowed to cool to a temperature at which the metal is fully solid.

摘要： A method and apparatus for casting metals in a DC mold to form an ingot having at least two layers formed by sequential solidification. The apparatus has at least one cooled divider wall at the entry end portion of the mold to divide the entry end portion into at least two feed chambers. Metal is fed to the chambers to form an inner layer and at least one outer layer. The divider wall has a metal-contacting surface for contacting the metal for the at least one outer layer, the surface being arranged at an angle to the vertical sloping away from the metal for the outer layer in a downward direction. The angle increases at positions on the divider wall spaced from a central section of the wall approaching each longitudinal end thereof. The apparatus is suitable for casting a metal having a high coefficient of contraction as an inner layer or core ingot.

摘要： A coolant or wiper control system for use in continuous casting mold for controlling and managing the coolants interaction with the castpart during casting. In some aspects of the process, the wiper framework is started sufficiently away from the bottom block so as not to interfere or cause/allow coolant to get into the bottom block; is then rapidly moved back to the emerging castpart during transient heat-up; and then moved away from the mold with the solidified castpart at a controlled rate to a predetermined steady state position or to a second transitory state of the casting.

摘要： The exemplary embodiments relate to the removal of cooling water used to cool the surface of an ingot as it is formed during casting. The cooling water is removed from the surface by directing jets of water onto the surface at an angle, and with a momentum, that causes the cooling water to be stripped from the surface when contacted with the jets, and to follow a path that prevents the cooling water from again coming into contact with the ingot surface at a position beyond the point of removal. The apparatus for this includes nozzles to create the water jets, and equipment for supplying water under sufficient pressure and rate of flow to the nozzles.
