A special aluminum alloy production equipment with high production precision

Abstract

The invention relates to special aluminum alloy production equipment with high production precision. The special aluminum alloy production equipment with high production precision comprises a shell; afirst motor, a stirring pool, a drain pipe, a hydrogen removing mechanism, a scraping mechanism and a plurality of paddles are arranged inside the shell; the hydrogen removing mechanism comprises anair exhaust unit, a non-return unit and a combustion unit; the scraping mechanism comprises a cross beam; and a moving groove, a limiting groove, a limiting block, a third motor, a drive wheel, a guide rail and a scraper blade are arranged inside the cross beam. According to the special aluminum alloy production equipment with high production precision, a large amount of hydrogen generated in theproduction process of an aluminum alloy can be removed through the hydrogen removing mechanism, the hydrogen is prevented from being adsorbed by the molten aluminum, certain mechanical properties of the aluminum alloy are prevented from being lost, the special aluminum alloy production equipment with high production precision can remove a stable oxide film formed on the surface of the melt of thealuminum alloy through the scraping mechanism, and oxide is prevented from forming shrink holes and gas holes in the melt of the aluminum alloy.

Description

technical field [0001] The invention relates to the field of new material equipment, in particular to a special aluminum alloy production equipment with high production precision. Background technique [0002] New materials refer to some materials that are newly developed or under research and development, and have superior performance, which have better performance than traditional materials. New material production equipment is based on human will, through a series of research processes such as physical research, material design, material processing, and test evaluation, to produce equipment that can meet various needs of new materials. The special aluminum alloy used in rail transit is a relatively important new material. [0003] However, in the process of aluminum alloy production, a large amount of hydrogen gas will be produced, which mainly comes from wet raw materials, wet melting tools and moisture in the air, and hydrogen gas is easily absorbed by molten aluminum,...

Problems solved by technology

[0003] However, in the process of aluminum alloy production, a large amount of hydrogen gas will be produced, which mainly comes from wet raw materials, wet melting tools and moisture in the air, and hydrogen gas is easily absorbed by molten aluminum, so that when the aluminum alloy is solidified, hydrogen gas Expelled from the aluminum alloy melt, shrinkage holes appear on the solid surface of the aluminum alloy, causing the aluminum alloy to lose some mechanical properties. Not only that, aluminum instantly forms very stable oxides on the surface of the aluminum alloy melt, and the oxides will form on the surface of the aluminum alloy Shrinkage cavities and pores are formed in the alloy melt, which affects the mechanical properties of aluminum alloys
