The casting process of 7075 seamless aluminum tubes pipe mainly includes melting, purification, impurity removal, gas removal, slag removal and casting process. The main process is:
(1) Ingredients: According to the specific number to be produced, the amount of addition of various alloy components is calculated, and various raw materials are reasonably matched.
(2) Smelting: The prepared raw materials are melted in the melting furnace according to the process requirements, and the slag and gas in the melt are effectively removed by degassing and slagging refining methods.
(3) Casting: The molten aluminum is cooled and casted into round casting rods of various specifications under certain casting process conditions through a deep well casting system.
Advantages of 7075 seamless aluminum tubes pipe: First, the advantages of welding technology: the welding technology of thin-walled copper-aluminum tubes suitable for industrialized production is called a particularly difficult problem and is the key technology for replacing copper with aluminum for connecting pipes of air conditioners.
The second is the service life advantage: from the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain moisture, the inner wall of the copper-aluminum connecting tube will not corrode.
The third is the energy-saving advantage: the lower the heat transfer efficiency of the connecting pipe between the indoor unit and the outdoor unit of the air conditioner, the more energy-saving. To
Fourth, it has excellent bending performance and is easy to install and move.
