PROBLEM TO BE SOLVED: To provide a ZrO-containing castable refractory capable of developing excellent corrosion resistance of ZrOeven in the case of a small ZrOcontent.SOLUTION: The ZrO-containing castable refractory is a castable refractory containing ZrOparticles as starting material particles, wherein the particle size distribution of starting material particles constituting the castable refractory is determined according to expression (1): P=100×(d/D)(1), wherein D represents a maximum particle diameter (mm) of the starting material particles constituting the castable refractory; P represents a cumulative amount (vol.%) of starting material particles passing through a sieve whose opening size is d (mm); and q is a coefficient in the range of 0.2-0.3. |
