摘要 |
The invention relates to a refractory for cast molding to be used as, for example, lining of a molten metal container, which contains a proper amount of an organic foaming agent generating an incombustible gas upon decomposition, such as 4,4-oxybis(benzenesulfonohydrazide). This refractory can solve the conventional problem of explosive cracking to be caused upon drying the refractory by heat. |
