Aluminum Plate is aluminum as the main raw material, and mixed with other alloy elements made of aluminum or aluminum. Aluminum Plate is an important basis for the development of China's national economy, widely used in aviation, aerospace, construction, printing, transportation, electronics , Chemical, food, pharmaceutical and other industries in the rapid economic development, driven by China's aluminum plate with the investment heating up, aluminum consumption continued to maintain steady growth.
Aluminum Plates Material by high temperature melting, the direct casting into the product method. Usually in the arc furnace melting, and then poured into the high temperature of the mold, and then by cooling crystallization, annealing or cutting made of products. Production mainly through the control of the melting atmosphere, melting temperature and cooling conditions to ensure high production efficiency, crystallization requirements and the formation of network structure.
Several key parameters in the Aluminum Plate casting process:
1. Smelting the general set of furnace temperature 1050 ℃, the process needs to monitor the material temperature, control the metal temperature does not exceed 770 ℃
2. At about 735 ℃ slag operation, the temperature is conducive to the separation of liquid
3. Refining generally use the second refining method, a refining and solid refining agent, the second refining using gas refining methods.
4. Furnace after the general 30min-1h need to be timely casting, or need to re-refining
5. Casting process need to continue to join Ai-Ti-B wire to refine the grain
