질문 # 83
Refractory abrasion is defined as the wearing away of the surface by:

A. coke buildup.
B. the scouring action of moving solids.
C. high-velocity gases.
D. high-velocity hydrocarbons.

정답：B

설명：
API TR 977 defines refractory abrasion in the context of erosion resistance testing:
"Abrasion is the wearing away of the surface by the mechanical scouring action of solids moving across the surface."
- API TR 977, Section 2
This distinguishes abrasion from gas or chemical attack and aligns with ASTM C704 test context.

질문 # 84
Which of the following is false per the requirements of API Standard 936?

A. Permanent linear change is determined with one 2 in. (50 mm) × 2 in. (50 mm) × 9 in. (230 mm) specimen.
B. Cold crush strength is determined using two 4-1/2 in. (144 mm) × 4-1/2 in. (114 mm) × 4-1/2 in. (114 mm) cubes.
C. Density shall be determined using cubes or erosion plates and linear change bars.
D. Abrasion resistance is determined using two 4-1/2 in. (114 mm) × 4-1/2 in. (144 mm) × 1 in. (25 mm) specimens.

정답：B

설명：
According to API Standard 936, the correct specimen dimensions for cold crush strength testing are:
"Test specimens for cold crushing strength shall be2 in. (50 mm) cubesamples prepared in accordance with ASTM C133."
-API Std 936, Section 6.4.2
This directly invalidates option A, which incorrectly states the specimen size as 4-1/2 inches.
For the other options:
Option B - Density determination:
API 936 states that density shall be measured using the same specimens used for linear change and abrasion resistance:
"Bulk density shall be determined using the same specimens prepared for the linear change and abrasion resistance tests."
-API Std 936, Section 6.4.3
"These specimens include cubes, linear change bars, and erosion plates."
-Appendix A, API Std 936
Option C - Abrasion resistance specimen size:
"Two 4-1/2 in. × 4-1/2 in. × 1 in. (114 mm × 114 mm × 25 mm) specimens shall be prepared for abrasion resistance testing."
-API Std 936, Section 6.4.4
Option D - Permanent linear change specimen size:
"Permanent linear change (PLC) is determined with a bar 2 in. × 2 in. × 9 in. (50 mm × 50 mm × 230 mm) cast in steel molds."
-API Std 936, Section 6.4.1
Therefore, Option A is the only false statement.

질문 # 85
A separation between adjoining parts of a refractory lining that allows small expansive movements, such as those caused by thermal change is known as

A. Thermal conductivity
B. Thermal expansion
C. Expansion joint
D. None of the above

정답：C

질문 # 86
Which function of refractories is to resist temperature?

A. Primary function
B. None of the above
C. Secondary function
D. Tertiary function

정답：A

질문 # 87
Cold wall refractory lined components shall be dried out by heating from:

A. the hot face only.
B. the cold face only.
C. the outside the steel shell.
D. inside an oven.

정답：A

설명：
Cold wall refractory systems are typically backed by steel shells, which are poor at withstanding the thermal stresses that come from reverse heating. API 936 and API TR 980 clearly emphasize thatthe heat-up or dryout process for cold-wall linings must always begin from the hot face- that is, the process-exposed surface.
Heating from thehot faceallows for controlled migration of moisture toward the cold face and eventual venting to the atmosphere. Conversely, heating from the cold face or steel shell side traps moisture between the hot impermeable material and the outer surface, leading to:
Steam buildup
Explosive spalling
Cracks in the material or at the interface with the steel
For these reasons,only the hot facemethod is specified unless the design and dryout plan justify a different method under special engineering review.
Reference:
API Std 936, Section 6.5.2: "Dryout shall be performed from the hot face only unless otherwise specified." API TR 980, Section on "Dryout of Cold Wall Systems": Highlights the mechanisms of vapor movement and the risks of reverse heating.
ASTM C1190(Referenced Method): Supports the use of correct drying schedules and methods.
