Embodiment 1

[0053] The equipment used in this embodiment to prepare metal sheets by simultaneous casting and rolling is shown in figure 1 .

[0054] figure 1 It is also a schematic diagram of the working process of synchronous casting and rolling filmless forming in the present invention. The molten metal 2 entering the tundish 3 is modulated by the temperature control system and the stirring system of the tundish 3 into a molten metal 2 suitable for synchronous casting and rolling. ; Control the pressure of the metal melt 2 through the pressure control 1, so that the metal melt 2 enters the synchronous casting and rolling zone 7 through the bottom discharge port 4 of the tundish 3, and the metal melt 2 is between the discharge port 4 and the crystallization plate 11 The lower interface of the synchronous casting and rolling zone 7 of the cavity begins to solidify, and dendrites 5 are rapidly formed. At this time, the crystallization plate 11 moves to the movement direction 10 of the cry...

Abstract

The invention provides a synchronous cast rolling mold-free molding method of a whole wall plate type thin-wall metal component and relates to a micro-scale synchronous cast rolling method and device. With the adoption of the method, the whole wall plate type thin-wall metal component with a complicated structure and high mechanical property requirements, such as an aluminum alloy or titanium alloy whole wall plate part of a high-speed delivery vehicle, can be directly prepared,. According to the preparation method provided by the invention, a production flow of the metal component can be greatly shortened, and a machining and heat treatment process needing to be repeatedly carried out in a conventional manufacturing method is saved, so that the energy consumption can be greatly reduced and the utilization efficiency of materials is improved. The method can be used for regulating and controlling the size precision and surface quality of the component through adjusting and controlling the thickness of an accumulation layer, and regulating and controlling the dense degree of the component, the thinning degree of crystal grains, and the metallurgical bonding quality of an accumulation layer interface by regulating and controlling a temperature field and a stress field in a synchronous cast rolling space, so that the near net molding, even net molding of the metal component can be realized.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a method for preparing thin-walled metal components such as integral wall plates by synchronous casting and rolling. Background technique [0002] The metal processing technology has developed from the initial casting and rolling process separately, to the continuous casting and rolling process, and then to the continuous casting and rolling process. The innovation of each process route has led to a substantial and rapid increase in production efficiency. [0003] Metal integral wall panels, that is, metal structural parts integrated with skin and ribs, are characterized by large, thin-walled, light-weight, complex structures, and high requirements for shape and dimension accuracy. They are important components of high-speed vehicles such as aviation, aerospace, and high-speed rail. part. It must not only meet the aerodynamic shape requirements of high-speed ve...
