Description

technical field [0001] The invention relates to the technical field of metallurgy and metal material preparation, in particular to an electromagnetic energy buffer launder for aluminum alloy grain refinement. Background technique [0002] In recent years, the research and application of deformed aluminum alloy forming parts have been widely concerned by people. In order to obtain deformed aluminum alloy formed parts with excellent performance, firstly, there must be a deformed aluminum alloy initial ingot with good quality. However, usually the deformed aluminum alloy ingot has a coarse structure, which is not conducive to the subsequent thermal processing of the ingot and also affects the performance of the product. Since grain refinement can reduce defects such as ingot segregation, improve the uniformity of the structure and its mechanical properties, and improve the formability in subsequent processing (such as extrusion and rolling), ensure that the grain size is fine ...

AI Technical Summary

Problems solved by technology

[0004] In actual production, the furnace is 3-30t, and the flow velocity in the launder is too high at 30t. In the process of grain refinement, the aluminum alloy electromagnetic energy grain refinement technology refines the aluminum alloy, which has a negative impact on the flow velocity of the aluminum alloy melt. Certain requirements, the flow rate of the aluminum alloy melt in the launder is too fast, and the electromagnetic energy is applied for a short time, which leads to the fact that the grain refinement effect of the aluminum alloy cannot reach the optimal level

At the same time, the electromagnetic energy grain refinement equipment in the previous invention is placed at the entrance of the launder, the flow rate is 2cm / s, the electromagnetic energy action area is 500mm, the processing time is 25s, the grain refinement rate is 3.61%, and there is grain refinement The problem of poor performance
