摘要： PROBLEM TO BE SOLVED: To provide an apparatus and method of unidirectional solidification casting that produces a uniformly controlled cooling rate.SOLUTION: Molten metal is injected uniformly into a mold 10 from a feed chamber 34 in a horizontal or vertical direction at a controlled rate on top of the metal already within the mold. A cooling medium is applied to the bottom surface of a base material, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casting, and low stresses throughout the casting.

摘要： PROBLEM TO BE SOLVED: To provide a mold structure where the flow of a molten metal is controlled in such a manner that the quantity of oxides present on an ingot surface can be made minimum in DC casting for aluminum.
SOLUTION: A DC casting mold 200 comprises a cooling tubular body 100 that has a thermally insulated insert 400 attached to its top surface. The thermally insulated insert has a bottom portion with a beveled sidewall 402, which forms an angle with a horizontal plane layer 130 of the molten metal and creates an eddy. The eddy causes a substantial number of oxides that are formed during the casting process to remain in the bottom sidewall portion of the thermally insulated insert of the mold, thereby substantially reducing the number of ingot surface imperfections that promote ingot cracking. In addition, the eddy promotes break-up of the oxides into smaller pieces as the oxides flow toward the cooled inner walls of the cooled tubular body, thereby having limited surface area for growth of an oxide layer.

摘要翻译：要解决的问题：提供一种模具结构，其中以这样一种方式控制熔融金属的流动，使得在铝的直流铸造中，在铸锭表面上存在的氧化物的量可以最小化。解决方案：直流铸造模具200包括具有附接到其顶表面的绝热插入件400的冷却管状体100。绝热插入件具有底部，其具有倾斜的侧壁402，其与熔融金属的水平面层130形成一角度并产生涡流。涡流导致在铸造过程中形成的大量氧化物保留在模具的绝热插入件的底部侧壁部分中，从而大大减少了促进锭裂纹的锭表面缺陷的数量。此外，当氧化物流向冷却的管状体的冷却的内壁时，涡流促进氧化物分解成更小的部分，从而具有有限的氧化物层生长的表面积。版权所有（C）2006，JPO＆NCIPI

摘要： Molten metal is injected uniformly into a mold from a feed chamber in a horizontal or vertical direction at a controlled rate, directly on top of the metal already within the mold. A cooling medium is applied to the bottom surface of the substrate, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casting, and low stresses throughout the casting. A multiple layer ingot product is also provided comprising a base alloy layer and at least a first additional alloy layer, the two layers having different alloy compositions, where the first additional alloy layer is bonded directly to the base alloy layer by applying the first additional alloy in the molten state to the surface of the base alloy while the surface temperature of the base alloy is lower than the liquidus temperature and greater than eutectic temperature of the base alloy - 50 degrees Celsuis.

摘要： A DC casting mold for casting molten metal alloy comprising a cooled tubula r body that has a thermally insulated insert attached to its top surface. The thermally insulated insert has a bottom portion with a beveled sidewall, which forms an angle wi th the horizontal melt surface layer of the molten metal and creates an eddy. The eddy causes a substantial number of oxides that are formed during the casting process to remain in the bottom sidewall portion of the thermally insulated insert of the mold, thereby substantially reducing the number of ingot surface imperfections that promote ingot cracking. In addition, the eddy promotes break-up of the oxides into smaller pieces as the oxides flow towar d the cooled inner walls of the cooled tubular body, thereby having limited surface area for growth of oxide folds. A method of casting molten metal alloys with improved surface quality is also disclosed.

摘要： A method of casting metal, comprising: providing a mold having a bottom that is selectively displaceable to provide at least two different surfaces and four sides defining a mold cavity therein, having at least one molten metal inlet structured to introduce a first molten metal horizontally into the mold cavity, a second molten metal inlet structured to introduce a second molten metal into the mold cavity; introducing molten metal into the bottom portion of the mold cavity through the first inlet; continuing to introduce molten metal from the inlet until a desired thickness; introducing the second molten metal above the first molten metal; and simultaneously directing a cooling medium against the bottom of the mold; whereby the molten metal is cooled unidirectionally through its thickness.
