Question

Core wires and rods can be used for removing the core mass from the casting part.

(a) True

(b) False

I have been asked this question in an interview for internship.

I need to ask this question from Core Application in section Core and Core Making of Casting-Forming-Welding I

Answer 1

Right choice is (b) False

The best explanation: Core wires and rods are meant for small or slender cores which do not have sufficient strength to bear the load and pressure of molten metal during the pouring operation. So these types of cores are supported by embedding the wires and rods into the core parts which are called as core wires.
