4 Terms and definitions
This standard shall not use the following terms and definitions!
Explosion
Refractory combustion In the process of rapid humidity rise, the gas generated inside the mountain is discharged in time to form a block or a front. 4.2
iWelding temperature temperaturrofati-exploslon If the test column does not burst below the final setting, but bursts above this fluidity, the fluid setting temperature is defined as the temperature change resistance of the material.
5 Principle
Put the sample in the test chamber at the set temperature, observe whether the sample is ripe during the actual return of the knife. The main resistance of the material to cracking is measured randomly.
6 Test sample
6.1 Size of the test sample
The size of the test sample is mmm5um
5.2 Preparation and maintenance of the test sample
The preparation and maintenance of the test sample shall be carried out in parallel at 3 times. 6.3 Number of samples
At the shortest point in the test, 3 samples shall be selected and tested. Test equipment and procedure shall be reduced.
7.1 Test preparation
YB/T4117—200 3
7.1.1.1 The test temperature should be within the range of 10°C. The test temperature should be within the range of 10°C. 7.1.1.2 The test furnace should be able to move 3! The rise rate should not be less than 5/\. 7.1.1.3 The height of the test furnace should not be less than 50mm×1.Grmmm. The test should not be accepted in the test furnace. The distance between the sample and the finished sample should be less than 52mm. The test should be able to pull the sample immediately. 7.2 Test process should be
72.1 The test furnace should be preheated to the set temperature for 3:m. 7.2.2 After demoulding, the test mold should be reduced to During the test, the temperature should be quickly reached and the door should be closed immediately. The temperature drop should not be too large within 42.10mia. The furnace should be set as the temperature source. The sample should be kept for 30min.7.2.3 Check whether the sample is cracked. If the sample is cracked, raise the temperature of the furnace and use another test bar to test it separately in 7.2.2. 7.2. The batch of test pieces should be transported after the test. If not, separate sample preparation should be carried out. During the test, the test pieces should be placed in the irradiated slurry.
3 Test results
31 If one of the three parallel test pieces is dry, it is considered that the sample is cracked. 8.2 If the test piece is tested collectively The rod is dried at the first set temperature change, and the resistance temperature of the test rod is considered to be less than this temperature: 83 If the sample does not burst under the set flow, but bursts at a higher temperature, then the set temperature is the fracture standard of the sample:
8.4 If the test bar still bursts at the required correct temperature at 10 o'clock, the test can be terminated and the resistance change at this temperature can be expressed.
