Embodiment 1

[0037] A casting and rolling device for an aluminum alloy slab, such as figure 1 As shown, it includes a casting nozzle (pouring nozzle) 1, a platform 2, a casting roll, an electromagnetic field generator 3, a pulse power supply 4 and a water spray cooling device;

[0038] There are two casting rolls, namely an upper roll 6 and a lower roll 7, which are placed symmetrically up and down, and the cooling water 8 is passed through the rolls; the platform 2 is located on the melt inflow side outside the casting roll; the casting nozzle 1 is placed on the platform 2, The nozzle outlet 9 is located between the upper roll 6 and the lower roll 7, and the height is below the centerline of the slab, which is used to send the melt 10 into the casting roll and prevent the casting zone 11 from solidifying in advance; the electromagnetic field generating device 3 is installed on the casting roll Outside, located on the melt inflow side, consists of a power supply and a magnetic field genera...

Embodiment 2

[0040] A casting and rolling device for aluminum alloy slabs, the structure of which is the same as that of the device in Example 1, the difference is that no pulse power supply is provided.

Embodiment 3

[0042] A casting and rolling device for aluminum alloy slabs, the structure of which is the same as that of the device in embodiment 1, the difference is that no electromagnetic field generating device is provided.

Abstract

The invention provides a casting rolling device and method for an aluminum alloy plate blank, belongs to the field of aluminum alloy casting-rolling equipment and production, and aims at solving the technical problems of the casting rolling method for producing thick aluminum alloy plate blanks. The device comprises a casting port, a platform, a casting-rolling roller, an electromagnetic field generating device and / or a pulse power supply, and a water spraying cooling device. The casting rolling method comprises the following steps: mixing materials of the aluminum alloy based on the content ratio of each component, and smelting into a melt; conveying the aluminum alloy melt into the casting port of the device to form a standing plate so as to form a solidified housing with proper thickness on the surface of the plate blank; starting the water spraying cooling device, the electromagnetic field generating device and / or the pulse power supply to perform casting-rolling after the standing plate is formed; stopping casting-rolling after the plate blank reaches a certain length, so as to obtain the aluminum alloy plate blank. With the adoption of the device and the method, a casting-rolling area can be prevented from early solidifying, so that the segregation of the plate blank can be reduced; in addition, the melt can be prevented from pollution while a structure is refined.

Description

technical field [0001] The invention belongs to the field of aluminum alloy casting and rolling equipment and manufacturing, and in particular relates to a casting and rolling device and a casting and rolling method of a relatively thick aluminum alloy slab. Background technique [0002] At present, the blank supply methods of industrial aluminum foil and sheet mainly include hot rolling method and casting rolling method. The process of the hot rolling method mainly includes semi-continuous ingot casting, heating, billet opening, face milling, heating, hot rolling, etc. There are many processes, high energy consumption, and a large one-time investment in equipment. The casting and rolling method is to directly pour liquid aluminum alloy into two rolls with cooling water inside, and directly produce a slab with a thickness of 6-8mm under the action of cooling and certain pressure. Therefore, compared with the hot rolling method, the casting and rolling method has the advanta...
