Most Upvoted Answer
Match the casting defects (Group A) with the probable causes (Group B)...
The correct answer is option 'B': P-4, Q-3, R-2, S-1. Let's understand why.
1. Hot tears (P) - Improper fusion of two streams of liquid metal (1)
Hot tears are cracks or fractures that occur in the casting during solidification due to improper fusion of two streams of liquid metal. This defect occurs when the metal does not flow smoothly and forms a weak point, leading to cracks.
2. Shrinkage (Q) - Volumetric contraction both in liquid and solid stage (3)
Shrinkage is a casting defect that occurs due to volumetric contraction in both the liquid and solid stages of the metal. It happens when the metal undergoes a reduction in volume during cooling and solidification, resulting in voids or cavities in the casting.
3. Blow holes (R) - Low permeability of the sand mould (2)
Blow holes are gas cavities or bubbles that are trapped within the casting during solidification. This defect is caused by the low permeability of the sand mould, which prevents the escape of gases generated during the pouring of molten metal.
4. Cold shunt (S) - Differential cooling rate (4)
Cold shunt is a casting defect that occurs due to differential cooling rates within the casting. It happens when some sections of the casting cool faster than others, causing thermal stresses and resulting in cracks or distortion.
In summary, the correct match for the casting defects and their probable causes is:
- Hot tears (P) - Improper fusion of two streams of liquid metal (1)
- Shrinkage (Q) - Volumetric contraction both in liquid and solid stage (3)
- Blow holes (R) - Low permeability of the sand mould (2)
- Cold shunt (S) - Differential cooling rate (4)
