Molten aluminum purification device and purification method for super-heat-conduction aluminum ingot processing

Abstract

The invention belongs to the technical field of aluminum ingot processing, particularly relates to a molten aluminum purification device for super-heat-conduction aluminum ingot processing and a purification method, and aims to solve the problems that an existing purification device is relatively simple in structure, poor in overall purification effect and low in purity of purified molten aluminum and provides the following scheme that the molten aluminum purification device comprises a purification barrel, and the outer wall of the upper side of the purification barrel is fixedly connected with a barrel cover; a top connecting base is arranged above the purification cylinder, a filtering assembly is arranged in the top connecting base, a supporting column is fixedly connected to the outer wall of the lower side of the top connecting base, the other end of the supporting column is fixedly connected with the outer wall of the upper side of the cylinder cover, and a primary purification assembly and a rotary aluminum oxide ball layer are arranged in the purification cylinder. According to the molten aluminum purification device, scum in molten aluminum is filtered through the filtering assembly, then purification operation is conducted twice, non-metallic inclusions and dissolved hydrogen in the molten aluminum are effectively removed, the quality of the purified molten aluminum is improved, and the situation that purification is not thorough in the conventional purification operation process is avoided.

Description

technical field [0001] The invention relates to the technical field of aluminum ingot processing, in particular to a liquid aluminum purification device and purification method for superconducting heat aluminum ingot processing. Background technique [0002] Aluminum is a silvery-white metal, which ranks third in the earth's crust after oxygen and silicon. The density of aluminum is only 34.61% of iron and 30.33% of copper, so it is also called light metal, aluminum It is a non-ferrous metal whose output and consumption are second only to steel in the world. The density of aluminum is only 2.7103g / cm3, which is about 1 / 3 of the density of steel, copper or brass. Because of its light material, aluminum is often used in the manufacture of automobiles , trains, subways, ships, airplanes, rockets, spaceships and other land, sea and air vehicles to reduce the weight and increase the loading capacity. [0003] According to different components, aluminum ingots can be divided into...

Problems solved by technology

[0005] An important link in the processing of superconducting thermal aluminum ingots is to purify the molten aluminum to improve the purity of the molten aluminum. The higher the purity of the molten aluminum, the better the quality of the subsequent processed superconducting thermal aluminum ingots. The structure of the purification device is relatively simple, the overall purification effect is not good, and the purity of the purified aluminum liquid is not high
