Heat-resistant aluminum alloy production

Aluminum alloy wire, especially heat-resistant aluminum alloy wire production, advanced production technology to ensure the product trial production and mass production. However, advanced and reasonable production equipment is also crucial. In the production of aluminum alloy wire products, China generally adopts the following process routes:

In the past, the melting, heat preservation and alloying of aluminum and aluminum alloys in China have adopted the shaft furnace melting and two rectangular heat preservation furnaces for thermal insulation and alloying. This model does not have to question the production of Pu aluminum. The melting rate is high. Two eight-ton rectangular holding furnaces can guarantee the continuity of production. Since Pu aluminum production basically does not need to add other metal elements, there is no problem of whether the aluminum liquid is even or segregated. For the production of aluminum alloys, especially the production of aluminum alloy as a conductor material, due to the high requirements of various technical indicators, this has to consider the suitability of rectangular holding furnaces. As we all know, due to the shape of the rectangular holding furnace, it is inevitable that there is a stirring dead angle. In the process of alloying with aluminum, no matter how it is stirred, the molten aluminum cannot be brought into a uniform state. As a result, segregation of the aluminum alloy solution or the final product occurs. Too much, too much fierce or improper operation will bring more serious consequences, that is, the alloy fluid seriously inhales, slagging. In addition, there are obvious temperature differences in the furnace in the rectangular holding furnace, and the temperature difference is also one of the factors that cause segregation. Thus, this mode of production has brought a greater impact on the quality of aluminum alloy wire products in China has been in a very stable.

Heat resistant aluminum alloys, especially 60% heat resistant aluminum alloys are in production. Due to the narrow range of allowable addition of zirconium, excessive addition of zirconium reduces the conductivity. On the contrary, it does not meet the heat resistance requirements. Due to the small amount of zirconium added, defects in the smelting and alloying equipment, and improper operation of the furnace, segregation of components occurs, and the quality and stability of the product can be imagined.

Practice has shown that aluminum alloys (including heat-resistant aluminum alloys, etc.) are used as conductor materials in the production. To ensure product quality and pass rate, there should be advanced and reasonable production equipment, advanced production technology and management, in order to ensure stable production of the product. Only by seeking ways to reduce production costs in a stable production can we face users at a reasonable price and take a place in China's huge transmission wire market.
