Segar cones are used for the determination of ____________ of refractories?
Correct answer: C. Softening temperature
- A. Electrical conductivity
- B. Spalling resistance
- C. Softening temperature
- D. Resistance to slag attack
Explanation
Seger cones bend or deform at characteristic temperatures, so they indicate the softening or refractoriness temperature of refractory materials. They do not directly measure spalling, electrical conductivity or slag resistance.
