摘要： The invention relates to a method for casting a melt (15) and to a casting tube (3) for a continuous casting system. The aim of the invention is to provide a method and casting tube (3) by means of which a cast product having a homogeneous, fine microstructure having a low proportion of segregation can be obtained. Said aim is achieved by a method comprising the following method steps: feeding the melt (15) from a casting distributor (1) into a chill mold (5), wherein the melt (15) is fed at least partially in the interior of at least one casting tube (3), and wherein the melt (15) is cooled in at least one casting tube (3), such that the melt (15) comprises a solid proportion of 10 to 60 wt % when exiting the casting tube (3); cooling the melt (15) in the chill mold (5), wherein an at least semi-solidified cast product is formed; and drawing the cast product out of the chill mold (5), wherein the cast product is supported, guided, and optionally further cooled by a strand support device downstream of the chill mold (5); wherein the cooling of the melt (15) takes place by means of at least one heat tube (8) or at least one thermosiphon.

摘要： A device for cooling molten metal comprises a body of thermally conductive material having an upper part (17) through which liquid coolant is passed and a lower part (18) which is submerged in the molten metal to be cooled. The lower part has a dimension which is greater than the corresponding dimension in a higher horizontal cross-sectional plane so that a skull of solidified metal (20) is locked to the body by extending around said greater dimension.

摘要： On coule le métal en un jet creux refroidi extérieurement entre un récipient de coulée et une lingotière et on injecte une matière métallique finement divisée dans le volume intérieur de ce jet creux. La matière finement divisée est mise en suspension dans un gaz non oxydant et elle présente une teneur en oxygène aussi faible que possible. Elle peut être constituée par une poudre du même métal que le métal coulé; on l'injecte alors en une quantité égale ou inférieure à 1 % du poids du métal coulé. En variante, elle peut aussi être constituée par une poudre d'un autre métal que le métal coulé; on l'injecte alors en une quantité comprise entre 0,5 et 10 % du poids du métal coulé. Sa granulométrie est de préférence inférieure à 1000 µm.

摘要： Metal forming process and apparatus are described.
The process comprises directing a stream (4) of atomised droplets of molten metal onto a chill surface (5) such that the metal is partially solidified to form a slurry of solidified metal suspended in liquid metal. The slurry is then collected (for example, in a casting mould 7) and then cast or otherwise formed before solidification is complete. It is particularly preferred that the stream of atomised droplets is directed onto a fully solidified layer (6) of the same metal on the chill surface.

摘要： A method and apparatus are provided for fabricating of continuous castings with fine and uniform microstructure, which can be used as feedstock for secondary processing routes, such as thixoforming, forging and machining or direct application in industry. An overheated liquid alloy is fed into a high shear device (for example, a twin-screw extruder) and sheared intensively to produce a sheared liquid alloy or a semisolid slurry, wherein the sheared liquid alloy is at a temperature close to its liquidus and the semisolid slurry is then transferred to a shaping device for production of continuous castings with fine and uniform microstructures through a solidification process. The shaping device is any device capable of forming continuous (i.e. infinite length) products, such as a direct chill (DC) caster (2) (DC rheocasting) for production of continuous billets, an extrusion die (8) (rheo-extrusion) for production of continuous bars or wires, or a twin-roll caster (twin-roll rheocasting) for producing of continuous strips. In all those cases, the cross-section of the continuous castings exhibits a microstructure in which a controlled volume fraction of fine and spherical primary particles are uniformly distributed in a fine structured matrix.
