Question

In dielectric core baker system, a metal used generally requires a low value of K (dielectric constant of material)

(a) True

(b) False

This question was addressed to me in an interview.

My question is based upon Dielectric Core Bakers in division Core and Core Making of Casting-Forming-Welding I

Answer 1

The correct option is (b) False

Explanation: In dielectric core baker systems, a dielectric material is used that should have a high value of K (K is the dielectric constant of the material), which basically provides the required electrical properties to operate the system efficiently. More the value of K, then more will be the effect of baker system on the baking cores.
