Description
Technical Field
The invention belongs to the technical field of metallurgy, and particularly relates to an efficient green aluminum alloy additive and a preparation method and application thereof.
Background
Aluminum and aluminum alloys have been widely used in the fields of aviation, aerospace, construction, automotive, rail transit, marine, machine manufacturing, electrical, electronics, instrumentation, chemical, architectural decoration, packaging, sporting goods, and the like. Aluminum and aluminum alloy materials have become the most used non-ferrous metal materials of secondary steel only.
The main method for adding alloy elements in the aluminum alloy smelting process comprises the following steps:
(1) the pure metal is added directly. Because the melting point of metals such as titanium, copper, manganese, iron, chromium, nickel and the like is much higher than the melting point temperature of aluminum, the melting speed is slow at the normal melting temperature of aluminum, the operation is required under the high-temperature condition, but the burning loss of the aluminum liquid is large, and the energy consumption is high.
(2) Adding the intermediate alloy. The melting point of the intermediate alloy is close to the temperature of molten aluminum, which is beneficial to the smelting of aluminum alloy, but the problems of overlarge melting point difference, large burning loss, high energy consumption and the like still exist in the preparation of the high-melting-point metal intermediate alloy.
(3) The high melting point alloy components are prepared by adopting metal additives. In the 70 th 20 th century, the company Foseco, LSM, AB, Hydelko, etc. in england developed a new generation of alloying element addition technology that was directly added as a metal additive (iron, copper, manganese, chromium, titanium, nickel, etc.). The metal additive research is started in China in the early 90 s of the 20 th century and is widely applied to the production of aluminum and aluminum alloy.
Because the metal additives such as titanium agent, copper agent, chromium agent and the like in the traditional formula are required to be added at a higher temperature generally exceeding 800 ℃ in the actual use process, the actual yield of about 90 percent can be obtained, but the energy consumption is high, the burning loss of aluminum liquid and metal elements is large, and the production cost is high. Meanwhile, a large amount of smoke dust is generated when the metal additive is added at high temperature, so that the environment and the health of personnel are greatly influenced.
Disclosure of Invention
The first purpose of the invention is to provide a high-efficiency environment-friendly aluminum alloy additive; the second purpose is to provide a preparation method of the high-efficiency environment-friendly aluminum alloy additive; the third purpose is to provide the application of the high-efficiency environment-friendly aluminum alloy additive.
The first purpose of the invention is realized by that the high-efficiency green aluminum alloy additive is composed of 70-90% of metal powder by mass and 100% of high-activity superfine aluminum powder by mass, and the balance of the high-activity superfine aluminum powder.
The second purpose of the invention is realized by uniformly mixing the raw materials in the formula ratio to obtain the target efficient green aluminum alloy additive.
The third purpose of the invention is realized by the application of the high-efficiency green aluminum alloy additive in the aluminum alloy smelting process.
In recent years, due to the fact that national environmental protection is increasingly strengthened, enterprise cost control and staff health awareness are continuously improved, enterprises put forward stricter requirements on the use of metal additives, ① is environment-friendly, smoke dust generated during adding is small, ② is energy-saving, the adding temperature is required to be below 800 ℃, ③ is efficient, and the actual yield is more than or equal to 90%.
The metal additive is used at the temperature of the aluminum liquid below 750 ℃, the actual yield can reach more than 95 percent, the smoke is small, and the smoke does not contain harmful gases such as fluorine, chlorine and the like, so that the metal additive has small influence on the environment and the health of operators. Compared with the prior art, the invention has the following obvious advantages: (1) the actual yield of the metal elements is 5-10% higher than that of the prior art. (2) When the smoke is added, the smoke is reduced by more than 90 percent, and the smoke does not contain harmful components such as fluorine, chlorine and the like and is harmless to human bodies and the environment. (3) The adding temperature is lower than 750 ℃, and the energy-saving effect is good.
