The hydrogen in aluminum can cause pores to form when the metal solidifies. To prevent this from happening, the hydrogen in the aluminum alloy can be removed by diffusing nitrogen particles into the liquid alloy. Nitrogen bubbles combine with hydrogen, rise to the liquid level and escape into the atmosphere.<\/p>\n<p>Since the solubility of hydrogen in the aluminum alloy liquid increases with the temperature rise, the alloy liquid will absorb a large amount of H2 during the smelting process. In the process of crystal solidification, due to the decrease in temperature, the surface layer of the alloy liquid solidifies first and the viscosity of the alloy increases. Although the solubility of hydrogen is reduced and needs to be precipitated from the molten metal, it is already very difficult. The stoma defect. The longer the melting and holding time, the higher the hydrogen content.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4402\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/11\/How-to-Remove-Dissolved-Hydrogen.jpg\" alt=\"How to Remove Dissolved Hydrogen\" width=\"500\" height=\"400\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/11\/How-to-Remove-Dissolved-Hydrogen.jpg 500w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/11\/How-to-Remove-Dissolved-Hydrogen-300x240.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<p><strong>How to Remove Dissolved Hydrogen<\/strong><\/p>\n<p>\u062a\u0642\u062f\u0645 AdTech <a href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/aluminum-casting-flux\/\">aluminum casting flux<\/a>, degassing unit for dissolved hydrogen removal. AdTech is dedicated to research and development, production and marketing of granular fluxes for the aluminum alloy casting process. AdTech refining fluxes utilize unique technology to enhance the traditional degassing and deslagging effect. According to the purpose of using flux for aluminum alloy, we offer refining flux, deslagging flux, covering agent, and oxide removal flux.<\/p>\n<p><a href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/online-degassing-device\/\">\u0622\u0644\u0629 \u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632\u0627\u062a \u0645\u0646 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645<\/a> is between the furnace and the casting machine, the main function is removing hydrogen and other residues. The average degassing efficiency is 60%. The rotor is made of silicon nitride. It has strong advantages in corrosion resistance, thermal shock resistance, oxidation resistance, wear resistance, mechanical strength and others. The rotor can diffuse the bubble to all corners of the inner cavity to the maximum extent. The degassing device can use a mixture of argon, nitrogen, and chlorine as an option. There are protection measures for using these gas. Before the molten aluminum enters the degassing equipment, the worker should switch off the heating element. When the temperature of the heater is close to the molten aluminum. Inject the inert gas into the rotor, and then fill the molten aluminum into the degassing box.<\/p>","protected":false},"excerpt":{"rendered":"<p>How to remove dissolved hydrogen in aluminum alloy?
