flow of the molten aluminum at an angle to the aluminum pump discharge, small chlorine-filled gas bubbles are sheared off and mixed rapidly in the turbulent flow found in the pump's discharge pipe. In actual practice, the flow rate of chlorine gas is increased until a slight vapor (aluminum chloride)

Aluminum Degassing Methods Measurements

2015/8/15The ability to degas molten aluminum is generally accomplished by using a purge gas, typically introduced into the melt by a rotary degassing unit. This degassing process is limited by thermodynamic laws; when purge gas bubbles are introduced to the melt, they collect hydrogen as they float toward the surface.

12.1 Primary Aluminum Production

The molten aluminum may be batch treated in furnaces to remove oxide, gaseous impurities, and active metals such as sodium and magnesium. One process consists of adding a flux of chloride and fluoride salts and then bubbling chlorine gas, usually mixed

Thermodynamic Analysis for the Refining Ability of Salt Flux for Aluminum

molten aluminum. Fluxes are mainly blends of chloride and fluoride salts with additives to instill specific properties. Most fluxes are based on a mixture of NaCl and KCl –13[11]. Aluminum recovery during remelting process of aluminum scrap from turning

Fluxes for melting aluminum [SubsTech]

2012/7/28Dr. Dmitri Kopeliovich Fluxes for melting aluminum are solid substances (commonly mixtures of chloride and fluoride salts) used in aluminum foundries in order to reduce the melt oxidation, minimize penetration of the atmospheric Hydrogen, absorb non-metallic inclusions suspended in the melt, keep the furnace/ladle wall clean from the built up oxides, decrease the content of aluminum

Degassing treatment of molten aluminum alloys

2012/7/28Fluxes composed of chlorine and fluorine containing salts are used for degassing molten aluminum alloys. Degassing fluxes are commonly shaped in form of tablets. Degassing operation starts when a flux tablet is plunged by a clean preheated perforated bell to the furnace bottom.

Treating aluminium with chlorine

We claim: 1. In a method of treating a molten aluminium alloy in which magnesium is present in a concentration of at least 1% and is the principal alloying element by continuous in-line fluxing with chlorine gas to remove hydrogen and/or alkaline metal impurities

Palmer Portable Rotary Degasser for Aluminum

The efficiency of aluminum degassing is determined by two factors, the transfer rate across the metal/gas interface and the total surface area available for transfer. Traditional hydrogen degassing systems bubbled specialty gases (Chlorine, Freon, or SF6) through the metal to speed the hydrogen transfer across the metal gas interface into large bubbles.

Shigemi Tanimoto Inventions, Patents and Patent

Abstract: Hydrogen gas and non-metallic inclusions are removed from molten aluminum by a process comprising the steps of rendering the portion above the surface of molten aluminum in a treating vessel where the molten aluminum is placed, an atmosphere of air having a lower dew point than that of the atmosphere and maintaining it as it is, introducing a treating gas into the molten aluminum

Molten salt oxidation of organic hazardous waste with

Molten salt oxidation is a flameless, robust thermal process, with inherent capability of destroying the organic constituents of wastes, while retaining the inorganic ingredients in the molten salt. In the present study, molten salt oxidation is employed for treating a typical organic hazardous waste with a high content of alkali salts.

Using Chemical Sensors to Control Molten Metal Processing

37 The magnesium is removed from the molten aluminum by injecting chlorine gas, which reacts with the molten aluminum to form AlCl 3 gas. If magnesium is present in the molten alloy, MgCl 2 forms by an exchange reaction with the AlCl 3 gas and then floats to the surface of the alloy, reducing the concentration of magnesium in the liquid aluminum.
