Abstract

The invention discloses a novel aluminum refining agent, and preparation method thereof, which is characterized in that the novel aluminum refining agent is composed of (by mass percentage) electrolyte 30-80%, heat generating agent 10-50% and degassing component 5-50%. Since the novel aluminum refining agent contains no sodium chloride component, addition of refined aluminum ash into an electrolytic bath can not cause effect on the running of the electrolytic bath, and by adopting excessive electrolyte as the main component for preparing the refining agent, the invention reduces the production cost, and facilities to environmental protection.

Description

technical field [0001] The invention belongs to the field of metallurgy and relates to a refining agent for aluminum refining, in particular to a novel aluminum refining agent for purifying aluminum melt. Background technique [0002] The liquid aluminum liquid produced by the aluminum electrolytic cell contains various impurities, mainly including alumina, carbon, aluminum carbide and residual electrolyte, among which alumina is the majority. These inclusions reduce the purity of aluminum liquid or aluminum alloy liquid, and affect the process performance, physical properties and mechanical properties of aluminum. Therefore, it is necessary to refine and purify aluminum liquid and aluminum alloy liquid to eliminate these gases and inclusions , Improve the quality of molten aluminum or aluminum alloy, and adding a refining agent to the molten aluminum or aluminum alloy for refining and purification is a commonly used measure. [0003] Judging from a large number of current ...
