Manufacturing method of high-heat-conduction aluminum alloy and product thereof

Abstract

The invention discloses a manufacturing method of a high-heat-conduction aluminum alloy and a product thereof. The manufacturing method comprises the following steps: preparing a pure aluminum ingot from basic raw materials; pure aluminum ingots are put into a reverberatory furnace in two batches, melting and stirring are conducted, and sampling is conducted respectively for component judgment; transferring the molten aluminum into a holding furnace from a reverberatory furnace, adding pure aluminum ingots for melting, raking slag, and judging components; preparing added raw materials, and confirming the dosage of master alloy silicon, iron, magnesium and pure aluminum ingots to be added; mother alloy silicon and iron are added and melted, and then component analysis is conducted; adding a pure aluminum ingot, melting and cooling, adding mother alloy magnesium, confirming components, and correcting if the components are insufficient; a deslagging agent is kept to be added into the furnace for degassing and deslagging operation, and then final component judgment is conducted; carrying out secondary degassing and deslagging operation on line; and casting an aluminum alloy ingot. The high-heat-conduction aluminum alloy has the beneficial effects of being good in forming machining and good in heat dissipation effect.

[0003] With the rapid development of science and technology, the performance requirements and precision of equipment are getting higher and higher. Precision equipment is accompanied by harsh operating environment requirements. Temperature control is an important part of ensuring the operation of equipment. The temperature control of most equipment It is inseparable from the radiator, but if the radiator wants to improve the heat dissipation performance, in addition to the structural change, the most fundamental thing is to improve the heat dissipation performance of the radiator material. Therefore, it is necessary to develop a more reasonable manufacturing method to prepare moldable and The processed high-quality heat dissipation materials can meet the equipment configuration with higher calorific value, and provide a guarantee for various equipment to increase the degree of integration and reduce the size; however, in actual production, the current aluminum alloy materials have poor thermal conductivity, and the current communication industry With the rapid development, the heat dissipation performance requirements of the products are also continuously improved. However, the heat dissipation performance of the current aluminum alloy products cannot meet the requirements of the communication industry.
