Problems solved by technology

Therefore, the cost of degassing is high, and because most of the methods of rotary injection are used, not only the fluctuation of the liquid level is serious, resulting in increased oxidation, but also it is not conducive to the overall uniform degassing inside the molten pool

Abstract

A process for cleaning the molten Al-alloy by removing hydrogen features that the inertial gas is sprayed onto top surface of molten Al-alloy contained in a degassing case via rotating nozzle while onto the bottom of the molten Al-alloy via the air-permeable bricks on the bottom of the degassing case.

Description

technical field [0001] The invention relates to a method for purifying a metal melt, in particular to a method for purifying an aluminum alloy melt for removing gas in the aluminum alloy, and belongs to the field of processing the aluminum alloy melt. Background technique [0002] The purification of aluminum alloy melt is a key technology to ensure the metallurgical quality of aluminum alloy materials, and reducing the hydrogen content in aluminum melt is one of the main purposes of aluminum melt purification. Aluminum melt dehydrogenation purification technology can be divided into two categories: adsorption purification and non-adsorption purification according to the principle of action. Adsorption purification adds adsorbents (such as gas, solid purifiers, etc.) During the contact process, chemical, physical or mechanical interaction occurs with the aluminum melt, so as to achieve the purpose of hydrogen removal. Non-adsorption purification is to change the equilibrium...
