Problems solved by technology

[0003] Grain size is an important factor determining the performance of aluminum alloy strips. At present, grain refiners are often used in industry, which can reach the first-grade grain size. The grain size is about 450 μm, but the cost of refiner is high. It is easy to precipitate during the process, which makes the quality of the cast-rolled sheet unstable, especia

Abstract

The invention discloses an ultrasonic external field continuous casting and rolling machine, which comprises a casting mouth (11) and a roller support column (1). The roller support column (1) is provided with a cross beam (3). An ultrasonicator (8) is slantways mounted in front of the casting mouth (11) in the direction vertical to the casting and rolling direction. Guiding bars of the ultrasonicator (8) are inserted into the aluminium alloy fused masses of the casting mouth (11). The invention provides the ultrasonic external field continuous casting and rolling machine which can refine the casting and rolling mechanisms, improve mechanical property and anisotropy, reduce or eliminate segregation, macro-defects and micro-defects in the process of continuous casting and rolling of aluminium alloy plate blank. The machine is convenient for maintenance and can realize standardization and serialization.

Description

technical field [0001] The invention relates to a casting and rolling device, in particular to an ultrasonic external field continuous casting and rolling device for material forming and control. Background technique [0002] Continuous casting and rolling of aluminum and aluminum alloy strip blanks has been valued by countries all over the world because of its advantages such as short process, low investment, energy saving and consumption reduction, and high economic benefits. At present, the aluminum strip produced by continuous casting and rolling has accounted for 70% of the total production in China and about 40% in the world. Domestic continuous casting and rolling equipment has grown to more than 300 sets. However, the conventional casting and rolling production process is currently limited to 1 *** series all, 3 *** series and 8 *** Part of the series, the deep-drawing properties of the continuous cast strip are significantly lower than that of the hot rolled str...
