Abstract

The invention provides an Al-RE-Y alloy refiner and a continuous casting and rolling preparation method thereof. The alloy refiner is prepared from the following elements in percentage by mass: 3.2-8%of RE, 0.8-4% of Y, and the balance of Al and other unavoidable impurities; the RE / Y mass ratio is 2-4, and RE is at least one element in La and Ce. After the Al-RE-Y alloy refiner is prepared by continuous casting and rolling, the rolled alloy indoor temperature tensile strength exceeds 120MPa, the elongation reaches 30%, and the comprehensive performance is excellent; and the preparation methodhas the advantages of green technology, simplicity, high efficiency, and suitable for large-scale production and the like, and the Al-RE-Y alloy refiner of continuous casting and rolling preparationhas obvious effect on grain refinement of aluminum and aluminum alloy.

Description

technical field [0001] The invention belongs to the field of industrial aluminum alloy and its manufacturing technology, and relates to an alloy refiner and a preparation method thereof, in particular to an Al-RE-Y alloy refiner and a continuous casting and rolling preparation method thereof. Background technique [0002] Aluminum alloy is a general term for alloys based on aluminum. It has the characteristics of low density and high strength, and has excellent specific strength. The main alloy systems are Al-Si system, Al-Cu system, Al-Mg system and so on. It has a wide range of applications in the fields of transportation, automobiles, machinery manufacturing, and aerospace. The grain refinement of aluminum alloy is the key to improve the mechanical properties of aluminum alloy. At present, the method of adding intermediate alloy is the main method. Although theoretically there are many ways to refine the grains of Al alloys, so far the Al-Ti-B master alloy is still the ...
