Solution

Para responder a esta pregunta, vamos a analizar cada opción una por una:

  1. The molten metal is cast into a continuous strand.

    • Esto es cierto. En la colada continua, el metal fundido se vierte en un molde y se solidifica en una hebra continua.
  2. The cross-section can be rectangular or circular.

    • Esto también es cierto. La sección transversal del metal colado puede ser de varias formas, incluyendo rectangular y circular.
  3. It is desirable for secondary metal-forming operations.

    • Esto es cierto. La colada continua produce piezas que son adecuadas para operaciones de conformado secundarias, como laminado o extrusión.
  4. The mold is reusable.

    • Esto no es cierto. En la colada continua, el molde no es reutilizable ya que se desgasta debido al contacto constante con el metal fundido.
  5. Casting rates are low.

    • Esto no es cierto. Las tasas de colada en la colada continua son generalmente altas, lo que es una de las ventajas del proceso.
  6. It is used primarily for small pieces.

    • Esto no es cierto. La colada continua se utiliza principalmente para producir grandes cantidades de metal en formas largas y continuas, no para piezas pequeñas.

Por lo tanto, las respuestas correctas son:

  • The molten metal is cast into a continuous strand.
  • The cross-section can be rectangular or circular.
  • It is desirable for secondary metal-forming operations.
