Question

Match the mold elements in the casting process with the most suitable function: 

 

• A. P-II, Q-IV, R-V, S-I, T-VI, U-III
• B. P-II, Q-V, R-VI, S-I, T-III, U-IV
• C. P-V, Q-I, R-VI, S-III, T-II, U-IV
• D. P-II, Q-IV, R-I, S-V, T-VI, U-III

Hint:

In casting processes, the mold elements play vital roles that help in controlling the solidification process, impurity removal, and the creation of internal cavities.

Answer 1

The Correct Option is A

Let's match the mold elements with their respective functions: 
\( \mathbf{P} \) (Blind riser) helps in the function of casting with internal cavity, so \( P-II \). 
\( \mathbf{Q} \) (Chill) helps in the faster solidification of metal, so \( Q-IV \). 
\( \mathbf{R} \) (Skim bob) is used for removal of impurities, so \( R-V \). 
\( \mathbf{S} \) (Core) is used to form internal cavities and features, so \( S-I \).
\( \mathbf{T} \) (Insulating sleeve) helps increase the solidification time by insulating, so \( T-VI \).
\( \mathbf{U} \) (Inoculant) is used to introduce nucleation sites, aiding in the formation of a fine-grained structure, so \( U-III \).
