Answer 2

Hello dear,

● Blow holes -
- Entrapment of gas bubbles during metal casting are called blow holes.
- This occurs due release of moulded gases during pouring.

● Removal of gas bubbles during steel casting -
- Use of rust free chills, chapels and other material
- Ramming the mould slowly
- Provide adequate venting in moulds
- Proper baking of cores
- Control of moisture content in moulding

Hope this helps you...
