CASTABLE REFRACTORY AND CASTING NOZZLE AND SLIDING NOZZLE PLATE USING SAME
The present invention has an object to improve a tolerance of a refractory to be used repeatedly or for a long period of time, such as a refractory for casting, especially a nozzle for casting and an SN plate. The refractory for casting of the present invention contains Al 4 O 4 C in the range of 15 to 60% by mass, both inclusive, an Al component as a metal in the range of 1.2 to 10.0 % by mass, both inclusive, and a balance including Al 2 O 3 , a free C, and other refractory component; a sum of Al 4 O 4 C, Al 2 O 3 , and the Al component as a metal is 85% or more by mass; and a content of Al 4 O 4 C (Al 4 O 4 C), a content of the Al component as a metal (Al), and a content of the free carbon (C) satisfy following Equation 1 and Equation 2. 1.0 ¤ C / Al 1 O 4 C × 0.038 + Al × 0.33 1.0 ¥ C / Al 4 O 4 C × 0.13 + Al × 0.67
