4 principle
In the provisions of the test temperature and a certain pressure of the air as a cooling medium under the conditions of a certain shape and size of the sample in the urgent situation
After the cold temperature mutation, the quality loss rate of the sample before and after the test is used to determine the anti-peeling property of the insulated refractory bricks.
5 equipment
5.1 Panel device
Mainly by the test sample brick, protective brick, insulation materials, panel frame composition. The outline of the concrete structure of the panel is shown in Fig.
5.2 Heating device
The heating device is used to test the heating and anti-peel test of the sample. Heating device temperature should be able to reach 1400 °C, the furnace temperature with heat
Galvanic measurement, heating process using automatic control, the temperature difference does not exceed ± 10 °C. In the process of moving the panel device, the temperature inside the heating device does not drop
More than 30 °C, and in 5min can be restored to the specified temperature. The concrete structure is shown in Fig.
