Abstract

The present invention relates to a method for purifying molten non-ferrous metal liquid and its equipment. Its method includes adsorptive purification by using purification gas and making it pass through molten non-ferrous metal liquid. The invention is characterized by that at the same time of making adsorptive purification by using gas, the evacuation is made over the molten non-ferrous metal liquid so as to form negative pressure to suck the molten liquid. Its equipment is formed from non-ferrous metal purification device and evacuation device that is connected with the space over the molten liquid in the purification device. Said purification device can be in monochamber structure, several chamber structure and chamber-free structure. Said method is high in efficiency, low in energy consumption and can save energy.

Description

technical field

[0001] The present invention relates to a method for purifying non-ferrous metal melts, in particular to an aluminum alloy for purifying molten aluminum and ensuring the quality and performance of castings in order to remove impurities such as hydrogen and oxides and other harmful substances in molten aluminum. Purification and refining method of molten metal, and equipment designed for the realization of the purification method. Background technique

[0002] Aluminum alloy will inhale hydrogen during the melting process, and will also oxidize to form alumina slag. If these hydrogen and alumina slag are not removed, there may be defects such as pores and slag inclusions in the casting, which will inevitably affect the performance, strength, and even appearance of the product. negative effect. Therefore, after the aluminum alloy is melted, it must be purified to remove harmful impurities and reduce the hydrogen content, so as to obtain pure molten metal and e...
