より耐熱性を評価することができる。Effects of the invention As is clear from the above explanation, the heat resistance measurement test device has the following effects:
The spray water rate can be adjusted within the range of 0 to 30 t/min and the flame temperature can be heated without changing arbitrarily, so even if a castable structure is suddenly overheated after natural curing, it can be maintained at a temperature that will not explode or melt. By understanding this, heat resistance can be evaluated.

By checking, spalling resistance can be evaluated. In this case, if natural cooling alone is not sufficiently severe, spraying water and forced cooling allows for even more severe spalling resistance evaluation.
