A method for controlling the casting defect of Al-Si-Mg alloy through grain refinement and improving the cooling speed by using hydropulse

摘要

The present invention relates to a casting defect control method through particle refinement and cooling rate improvement of Al-Si-Mg alloy by electron pulse treatment. Its purpose is to provide a method that can be processed in one process without using expensive materials by using expensive additives such as existing gas control, refiner, and improved treatment agent. Particle miniaturization of Al-Si-Mg alloy by electron pulse treatment to remove casting defects of Al-Si-Mg alloy by scanning electron pulses into the Al-Si-Mg alloy by an electron pulse generator located outside the molten metal And a method for controlling casting defects by improving a cooling rate, and a method for manufacturing a low-grade aluminum alloy containing a large amount of Fe into a high-quality product.
