The invention discloses a method for reducing the depth of a coarse grain ring of a 2A50 alloy extruding bar. The method for manufacturing the alloy extruding bar comprises the steps of ingot casting preparation, ingot casting heating, an extruding technique and a quenching technique; and the component of an ingot casting comprises Cr and Zr; in a specific test, the Cr and Zr are added to be the component of the ingot casting so that the depth of the coarse grain ring of the 2A50 alloy extruding bar is reduced, the yield of a product is improved, and the economic loss is lowered. Thus according to the method for reducing the depth of the coarse grain ring of the 2A50 alloy extruding bar provided by the invention, the depth of the coarse grain ring can be reduced, the yield of the product can be improved, and difficulty of the field at the present stage is solved.
Description
technical field [0001] The invention relates to the field of aluminum alloy extrusion processing, and more specifically, designs a method for reducing the depth of coarse crystal rings of 2A50 alloy extrusion rods. Background technique [0002] In the field of aluminum alloy extrusion processing, the depth of the coarse grain ring directly reduces the physical and chemical properties of the product, reduces the pass rate of the product, and even causes huge economic losses. [0003] As far as 2A50 alloy is concerned, because of its strong plasticity in hot state and easy forging and stamping, its extruded bars are often used as forging blanks in the aerospace field. In order to make the 2A50 alloy extruded rod further meet the requirements of the aerospace field, it is necessary to improve its performance by reducing the depth of the coarse grain ring of the rod. [0004] As far as the research status is concerned, there are many factors that affect the depth of coarse-grai...
