REFRACTORY FOR STEEL CASTING, PLATE FOR SLIDING NOZZLE DEVICE, AND METHOD FOR PRODUCING REFRACTORY FOR STEEL CASTING |
摘要 |
The problem of the present invention is to suppress destruction of a refractory which contains a metal aluminum. The refractory of the present invention is characterized by that the refractory is a refractory for steel casting which includes a refractory material containing a free carbon in the range of 1 to 10% by mass, both inclusive, a metal aluminum in the range of 1 to 15% by mass, both inclusive, and a metal oxide in a balance; and the refractory for steel casting satisfies Equation 1, provided that a metal aluminum content in the refractory is designated by Al% by mass, an apparent porosity thereof is designated by P%, and a bulk density thereof is designated by D. 0.31 × A 1 ‰¤ P ˆ’ 4 / D |
