A billet casting system is a method used in metal casting to produce billets, which are semi-finished metal products with a rectangular or square cross-section.

1. Purpose of Billet Casting:

   • Billet casting is used to produce uniform, semi-finished metal products with a rectangular or square cross-section.

2. Casting Methods:

   • Continuous Casting: Molten metal is poured into a tundish and solidifies as it passes through a water-cooled mold.
   • Ingot Casting: Molten metal is poured into molds to create ingots, which are further processed into billets.

3. Materials Used:

   • Billet casting can be applied to various metals like steel, aluminum, and copper alloys.

4. Equipment:

   • The process involves a tundish, casting mold, cooling system, and other auxiliary components. Continuous casting machines are commonly used.

5. Advantages of Billet Casting:

   • Efficient use of raw materials.
   • High production rates.
   • Improved metallurgical properties due to controlled solidification.

6. Applications:

   • Billets find applications in construction, automotive, and manufacturing industries.

7. Quality Control:

   • Stringent measures are in place to ensure uniformity and structural integrity.

8. Post-Casting Processes:

   • Billets may undergo additional processes like heat treatment, hot rolling, or extrusion for desired properties.
