YB/T 4117-2003Test method for explosion resistance of dense refractory castables (English PDF)

Foreword

This standard is proposed and managed by the National Technical Committee for Refractory Standardization.

This standard is approved by the State Economic and Trade Commission.

1 Scope

This standard specifies the terms and definitions, principles, samples, test equipment and procedures, and tests for the test method for the burst resistance of dense refractory castables.

Results and test report.

This standard is applicable to the burst resistance test of dense refractory castable below 1000 °C.

Other tests for the burst resistance of unshaped refractories can also be found in this standard.

3 Safety tips

This test is dangerous.

4 Terms and definitions

This standard uses the following terms and definitions.

During the rapid temperature rise of the refractory castable, the pulverizing damage or cracking caused by the gas generated inside cannot be discharged in time.

If the sample does not burst at a set temperature and bursts at a temperature above 50 ° C, then the set temperature is defined as the resistance of the material.

Burst temperature.

5 Principle

The sample was placed in a test furnace at a set temperature, and the sample was observed to burst when it was rapidly heated. Anti-burst of refractory castable it is measured by the anti-burst temperature.
