The principle of aluminum ingot casting is the physical process of cooling and crystallizing liquid aluminum into solid aluminum ingots through casting. The process flow is as follows:

 

1. Aluminum tapping: take the aluminum liquid out of the furnace;

2. Slag removal: remove impurities and slag from the aluminum liquid;

3. Weight inspection: weigh the aluminum liquid;

4. Batching: mix aluminum liquids of different components as needed;

5. Furnace loading: load the mixed aluminum liquid into the furnace;

6. Refining: refine the aluminum liquid to improve its purity and quality;

7. Casting: pour the refined aluminum liquid into the mold and wait for it to cool and solidify;

8. Aluminum ingots for remelting: inspect and weigh the cast aluminum ingots, and store qualified products;

9. Finished product inspection: check the appearance, size, weight and other indicators of the aluminum ingots;

10. Finished product weight inspection: weigh the aluminum ingots;

11. Storage: store qualified aluminum ingots in the warehouse. During the casting process, it is necessary to pay attention to controlling parameters such as temperature, time, and pressure to ensure the quality and performance of the aluminum ingot. At the same time, it is also necessary to pay attention to safety protection to avoid accidents such as burns.

Aluminum ingot casting is the process of making aluminum ingots through melting and casting processes. The process usually includes the following main steps:

1. Raw material preparation – Raw material selection: Select high-purity aluminum ore (such as bauxite) or recycled aluminum as production raw materials.

– Pre-melting treatment: Clean and pre-treat the raw materials to remove impurities and unnecessary substances.

2. Melting – Furnace heating: Put the aluminum raw materials into the furnace and heat them to the melting point of aluminum (about 660°C) through high temperature to transform them into liquid aluminum.

– Control the melting temperature: During the melting process, ensure that the temperature is kept in a suitable range to prevent the aluminum liquid from overheating or overcooling. – Impurity removal: During the melting process, add deoxidizers or other chemicals to remove oxides and impurities in the aluminum liquid.

3. Pouring – Mold preparation: Prepare the mold for the aluminum ingot according to the needs, usually a casting trough or a casting mold.

– Pouring: Pour the molten aluminum liquid from the furnace into the mold and cast it into the shape of an aluminum ingot. – Cooling: Allow the aluminum liquid to cool and solidify in the mold to form a solid aluminum ingot.

4. Demolding and post-processing – Demolding: After the aluminum ingot cools, remove it from the mold.

– Inspection and trimming: Check the quality of the aluminum ingot, including appearance, size and other characteristics, and trim and clean it if necessary.

5. Storage and transportation – Storage: Store the aluminum ingots according to specifications and requirements for subsequent use.

– Transportation: Transport the aluminum ingots to the next processing stage or customer as needed.

The aluminum ingot casting process requires strict control of the melting temperature and casting conditions to ensure that the quality of the aluminum ingot meets the standards. Each step involves precise control and processing to ensure the performance and appearance of the final product.
