This method is called flux injection.<\/p>\n<p><img class=\"alignnone size-full wp-image-7395\" src=\"http:\/\/www.adtechamm.com\/wp-content\/uploads\/2020\/10\/Aluminum-melting-loss.jpg\" alt=\"P\u00e9rdida por fusi\u00f3n del aluminio\" width=\"800\" height=\"600\" srcset=\"https:\/\/www.adtechamm.com\/wp-content\/uploads\/2020\/10\/Aluminum-melting-loss.jpg 800w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2020\/10\/Aluminum-melting-loss-300x225.jpg 300w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2020\/10\/Aluminum-melting-loss-768x576.jpg 768w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2020\/10\/Aluminum-melting-loss-700x525.jpg 700w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>Aluminium Degassing Process In Casting can greatly improve the quality and yield of aluminum products, thereby increasing the profitability of aluminum melting and casting plants.
