Preparation method of fusion casting aluminum bar for section aluminum

Abstract

The invention discloses a preparation method of a fusion casting aluminum bar for section aluminum. The preparation method comprises the steps of weighing of a raw material for preparing the aluminumbar, smelting of the raw material of the aluminum bar, refining, fusion casting, extrusion, mechanical pretreatment, degreasing, alkaline washing, water washing, oxidization, surface treatment, the coloring process, the spraying process, the curing process and coating of an anticorrosive coating with the thickness being 20-50 microns on the outer surface of the aluminum bar. The aluminum bar prepared through the method is high in weather resistance, and the performance of the aluminum bar is improved. Moreover, the aluminum bar is energy-saving, environment-friendly and good in anticorrosion effect, the good oxidation resistance of the aluminum bar can be guaranteed. The slag content of the aluminum bar is low. A refining machine is used for spraying a refining agent to an alloy aluminum solution to conduct slag removal treatment, and slag removal treatment is further conducted through a ceramic filter plate. Slag inclusions in the alloy aluminum solution are effectively removed. The slag content of the aluminum bar is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile processing, and specifically refers to a method for preparing aluminum profile cast aluminum rods. Background technique [0002] The aluminum profile titanium plating process belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The aluminum profile process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality, and good effect. The hardness of the film layer is HV≈1500, and it is 150 times more wear-resistant than 22K gold plating under the same conditions. It can be processed into a variety of bright aluminum profi...
