Abstract
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, has improved tolerance. The refractory for casting contains AlOC 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 AlO, a free C, and other refractory component; a sum of AlOC, AlO, and the Al component as a metal is 85% or more by mass; and a content of AlOC (AlOC), a content of the Al component as a metal (Al), and a content of the free carbon (C). The contact of the free carbon satisfies the following Equation 1 and Equation 2:1.0≦C/(AlOC×0.038+Al×0.33)  (Equation 1)and1.0≧C/(AlOC×0.13+Al×0.67)  (Equation 2).
