[0045] first embodiment, refer to figure 1 , an example of a rapid solidification laminated compound preparation metal ingot device designed by the present invention, including: a rapid quenching belt forming system 1, an acceleration system 2, a heating system 3, a deflection system 4, a laminated composite system 5 and a powder distribution system 6, specifically land:

[0046] The quenching belt forming system 1 is composed of a crucible 11 , a crucible heater 12 , a valve 13 and a quenching roller 14 . The bottom of the crucible 11 is provided with a slit, and the crucible heater 12 is induction heating, which is installed around the side wall of the crucible 11, and the crucible heater 12 is equipped with a temperature controller T1, so as to control the temperature of the molten metal 91. 10-500°C above the liquidus.

[0047] In some other embodiments, the slit is replaced by a row of fine holes, and the function of the fine holes is the same as that of the slit, whi...

[0063] second embodiment , continue to refer to the first embodiment, and refer to figure 2 , the rapid solidification lamination composite preparation metal ingot device of this embodiment does not include the deflection system 4, that is, the straight-flying belt 94 after heating does not need deflection, but uses the self-gravity of the straight-flying belt 94 to achieve a certain deflection. The receiver 511 reciprocates up and down (refer to figure 2 Arrow in the middle plate type receiver 511), continuously accepts the straight-flying belt 94 to form the bonding belt 96. Make the straight-flying belt 94 move to the right and form the bonding point with the metal ingot 97 to become the bonding tape 96, the receiver 51 moves downwards and pulls the bonding tape 96 to shift downwards, while the bonding point moves upwards, and the bonding tape 96 Combine with the metal ingot 97 successively from bottom to top, so that the metal ingot 97 is thickened by one layer, and a...

[0064] third embodiment , continue to refer to the second embodiment, and refer to image 3, the rapid solidification lamination compound preparation metal ingot device in this embodiment does not include the deflection yoke 4 , and the receiver 51 adopts a cylindrical receiver 514 . The continuous rotation of the cylindrical receiver 514 produces a deflection force, and the adhesive tape 96 is combined with the metal ingot 97 under the action of the heater 53 and the compactor 52. The continuous rotation of the cylindrical receiver 514 realizes that the adhesive tape 96 is in the receiver The continuous layering of the surface, likewise, the receiver is able to move to the right.

Abstract

The invention relates to the technical field of metal ingots, in particular to a device for preparing a metal ingot through rapid solidification and lamination compounding. The device comprises a rapid quenching belt forming system which is used for melting metal to prepare a solid rapid quenching belt which is kept at a set temperature and feeding the rapid quenching belt into an accelerating system; the accelerating system can accelerate the rapid quenching belt and separate the rapid quenching belt from a liquid beam carried by the rapid quenching belt to form an independent rapid quenchingbelt; a heating system is used for heating the independent rapid quenching belt from the accelerating system to keep the independent rapid quenching belt at a set temperature; a deflection system isused for applying deflection force to the rapid quenching belt from the heating system to enable the rapid quenching belt to deviate from the original movement direction; and a lamination compoundingsystem is used for depositing the rapid quenching belt from the deflection system onto a receiver, and a lamination compounding cast ingot is formed through a compactor. According to the device, rapidsolidification and lamination compositing are carried out at the same time, the defects which cannot be avoided by a conventional casting method can be effectively avoided, casting defects and sintering holes are well eliminated, and high-quality metal ingots can be manufactured in a short process.

Description

technical field [0001] The invention relates to the technical field of metal ingots, in particular to a device for rapidly solidifying laminated composites for preparing metal ingots. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Metal ingots prepared by conventional melting and casting methods generally contain various defects such as shrinkage cavities, porosity, and component segregation, and the larger the size of the ingot, the more serious these defects are, which leads to a significant decline in the performance of the metal. For large-sized ingots with high metal element content and complex composition, these defects are inevitable due to the slow ...
