Embodiment

[0041] Batching and loading furnace: prepare materials according to the batching plan, and configure various materials required for production through weighing instruments according to the proportion of materials. First put the aluminum scrap into the melting and casting furnace for bottoming, so as to protect the bottom of the furnace from being damaged by large pieces of metal material, and then put in aluminum ingots, etc. Smelting: Close the furnace door to enter the smelting stage, use natural gas as fuel to melt into aluminum melt, the temperature is controlled at 750-780 ℃, and the time is about 4 hours.

[0042] Slag removal: remove the scum on the surface of molten aluminum after smelting out of the furnace body, and improve the cleanliness of molten aluminum by manual slag removal. Adjusting the ingredients: After the slag removal is completed, add magnesium ingots, silicon ingots and other materials according to the process requirements, and stir evenly. If the ingr...

Abstract

A specific manufacturing method of the aluminum profile casting technology comprises the following steps that S1, firstly, burdening and charging are conducted, and raw materials are prepared; s2, the raw materials are poured into a casting furnace to be smelted; s3, deslagging the raw materials, and adjusting components; s4, refining the raw materials; s5, casting treatment; and S6, saw cutting and homogenizing treatment are carried out. The smelting and refining steps are adopted, waste gas is exhausted through nitrogen in the refining process, meanwhile, slagging-off is conducted after smelting and refining are completed every time, in the raw material slagging-off process, feeding is conducted again according to the analysis result, components are adjusted, the components are rapidly stirred and mixed, the alloy content of a product is overall increased, and the product is high in quality.

Description

technical field [0001] The invention relates to the technical field of aluminum profile processing, in particular to an aluminum profile melting and casting process. Background technique [0002] Aluminum is a metal element, the element symbol is Al, and it is a silver-white light metal. Extensible. Commodities are often made into rods, sheets, foils, powders, ribbons and filaments. In moist air, it can form an oxide film that prevents metal corrosion. Aluminum powder can burn violently when heated in the air, and emit a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. Relative density 2.70. Melting point 660 ℃. Boiling point 2327 ℃. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and it is the most abundant metal element in the earth's crust. The development of the three important industries of aviation, const...
