Problems solved by technology

However, limited by the existing processing technology level, it is extremely difficult to process nozzles with a diameter of ≦1mm on a graphite rotor with a diameter of ≧200mm, resulting in a large diameter of the bubbles formed by the traditional graphite rotor nozzle and low hydrogen removal efficiency

Abstract

The invention provides a controlled synthesis process of a functionalized ordered macroporous (less than or equal to 1mm) graphite rotor for aluminum alloy refining, which comprises the following steps of: providing a pore-forming template, filling coke powder and the pore-forming template into a mold sheath, and performing isostatic pressing to obtain a rotor blank; the rotor blank is put into a roasting furnace to be sintered, and the rotor blank is converted into a carbonized composite material; putting the carbonized composite material into a graphitization furnace for graphitization sintering, so that the carbonized composite material is converted into a graphite composite material; and dipping the graphite composite material in a corrosive liquid to remove the annular hollow-out body made of the metal material and the branches made of the metal material. According to the preparation method, the graphite composite material with an ordered macroporous (less than or equal to 1mm) structure can be prepared, and on the basis, the functionalized graphite composite material is applied to development of a graphite rotor with a small nozzle aperture (less than or equal to 1mm), so that the bottleneck of the level of the prior art is broken through, and the quality of an aluminum melt is further improved.

Description

technical field [0001] The invention relates to a preparation technology of a novel graphite composite material, in particular to a controlled synthesis process of a functionalized ordered macroporous (≤1mm) graphite rotor for aluminum alloy refining. Background technique [0002] High-purity dense graphite material has the advantages of excellent high temperature mechanical properties, good thermal shock resistance and corrosion resistance, so it has been widely used in metallurgy and other fields. For example, in the aluminum processing industry, high-purity and dense graphite materials are generally used to prepare graphite rotors with regular pore structure, which are used as key components of hydrogen removal devices to purify aluminum melts. [0003] The effect of graphite rotor for purifying aluminum melt mainly depends on its internal pore structure and pore size, etc. This is because the reasonably distributed pore structure can effectively avoid the gas flux (N 2 ...
