Abstract

The invention relates to the technical field of cast rolling of aluminum alloy materials, and discloses a method for producing a 3003D plate through a continuous cast rolling method and application of the 3003D plate. The method comprises the following steps: (1) melting an aluminum ingot in a smelting furnace, and adjusting chemical components; (2) transferring the alloy liquid into a standing furnace, standing, refining, degassing and filtering; (3) the alloy liquid enters a casting and rolling machine from a casting nozzle to be subjected to continuous casting and rolling to form a plate blank, the roller diameter of a roller is 845-855 mm, the length of a casting and rolling area is 40-50 mm, the casting and rolling speed is 550-650 mm / min, and the temperature of a front box is 675-685 DEG C; and (4) the plate blank is conveyed to a coiling machine through a guide roller to be coiled into a coiled material. The 3003D produced through continuous cast rolling is the same as the 3003D produced through casting in metallographic structure, and the plate is stable in performance and can be widely applied to the fields of automobile battery materials and new energy.

Description

technical field [0001] The invention relates to the technical field of casting and rolling of aluminum alloy materials, in particular to a method for producing 3003D plates by continuous casting and rolling and the application of 3003D plates. Background technique [0002] Continuous casting and rolling is the combination of continuous casting and rolling deformation in one process. While the molten aluminum is solidified, it is subjected to a certain pressure to produce a certain amount of plastic deformation; while melting and casting is to pass the liquid metal that meets the requirements through a series of processes. The transfer tool is poured into a mold with a certain shape, and the process of obtaining an ingot of a certain shape and size after cooling. [0003] The advantages of continuous casting and rolling are simple and centralized equipment, energy saving and consumption reduction, less geometric waste such as cutting heads and tails, high yield and low produc...
