Improvement of melting and casting technology

The quality of the ingot directly determines the final quality of the aluminum alloy All new scientific and technological means should be used to improve the metallurgical quality of aluminum alloy ingots.

 
1. Optimize the chemical composition of aluminum alloy, the ratio of main elements, and the content of trace elements, and continuously improve the purity of aluminum ingots.

 
2. Strengthen and optimize the online purification technology of aluminum melt to minimize the content of gas and inclusions in the melt. Gas refers to hydrogen.

 
3. Strengthen, optimize, refine and modify the technology, and continuously improve and improve some refinement processes and modify the process.

 
4. Use advanced aluminum melting furnaces and high-efficiency nozzles to continuously improve smelting technology and thermal efficiency. There is a gas furnace, which is a round, tiltable, and openable computer-controlled gas furnace. These gas furnaces are developing towards large-scale automation.

 
5. Use advanced casting methods, such as electromagnetic casting, oil-gas mixed lubrication casting, short crystallizer casting, etc. These methods can improve production efficiency, improve the quality of aluminum alloys, save energy, and reduce costs.

 
6. Use advanced homogenization equipment and technology to improve the uniformity of chemical composition, organization and performance of aluminum ingots.
