Abstract

The invention discloses an alloy melt hydrogen removal device and an online hydrogen removal method thereof. The device comprises a purifying tube which comprises an alloy melt inflow end and an alloy melt outflow end, Ti-Mo alloy particles are evenly placed into the purifying tube, and the alloy melt outflow end is provided with a first sealing plate used for filtering the Ti-Mo alloy particles. The alloy melt hydrogen removal device is simple in structure, convenient to install and replace, low in hydrogen removal cost, good in hydrogen removal effect and easy to apply to industrial production. Besides, the online hydrogen removal method based on the alloy melt hydrogen removal device is few in process procedure, equipment is convenient to install and replace, and the hydrogen removal effect is good. A magnesium alloy melt prepared by means of the device and the method can remarkably reduce the content of hydrogen in the melt, metallurgical quality of castings is improved, and the device and the method have good application prospect in industrial production.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a hydrogen removal device for magnesium alloy melt and an on-line hydrogen removal method integrating physical and chemical reactions. Background technique [0002] The liquid quality of aluminum alloy or magnesium alloy (including the content of gas and inclusions, etc.) directly affects the quality of castings. In the smelting process of magnesium alloys, the dissolved gas is mainly hydrogen, and the presence of hydrogen tends to aggravate the formation of porosity. The hydrogen in the magnesium melt mainly comes from the moisture in the flux, the moisture adsorbed on the metal surface and the moisture brought by the metal corrosion. [0003] At present, the methods for removing hydrogen from magnesium alloy melts mainly fall into the following two categories: [0004] 1) The method of introducing gas mainly includes the method of introducing inert gas (such as argon or ...
