Abstract

The invention relates to a cooling water angle adjustable crystallizer for aluminium alloy casting. An upper cover is connected on the body, the body is provided with a cooling water cavity, the front and back rolling faces of the cooling water cavity are respectively provided with a rolling face cooling pipeline, the rolling face cooling pipeline is communicated with the rolling face cooling water cavity, the left and right narrow faces of the cooling water cavity are respectively provided with a narrow face cooling pipeline, the narrow face cooling pipeline is communicated with the narrow face cooling water cavity, the four corners of the bottom of the body are respectively provided with a fixed block, the two ends of the front and back rolling face cooling pipeline and the two ends of the left and right narrow face cooling pipeline are respectively movably connected with the corresponding fixed block by a slide block, and the front and back rolling face cooling pipeline and the left and right narrow face cooling pipeline are uniformly distributed with cooling water holes. A cooling pipeline is additionally arranged below the body of the crystallizer, the cooling pipeline is designed with cooling water hole, the cooling water hole is separated from the water cavity of the crystallizer body; the fixed block and slide block structure causes the cooling pipeline to rotate around ingot casting water seeing point, thus achieving the aim of changing cooling water spraying angle.

Description

technical field [0001] The invention relates to a crystallizer with adjustable cooling water angle for aluminum alloy casting, which belongs to the technical field of aluminum alloy semi-continuous casting. Background technique [0002] Direct cooling semi-continuous casting is currently the main way to produce aluminum alloy round ingots and slabs, and the crystallizer is one of the core tools for aluminum alloy semi-continuous casting. During the production process, the molten aluminum is constrained to form in the crystallizer, moves down with the dummy head, and then the cooling water in the crystallizer is sprayed onto the solidified shell at a certain angle to completely cool the ingot. The cooling water is sprayed to the ingot at different angles, and the cooling effect is also different. Generally, when the cooling water in the crystallizer is 15°-30° to the center line of the ingot, the cooling effect sprayed on the surface of the ingot is stronger. [0003] In the...
