Embodiment 1
[0024] The present invention proposes a special corundum self-flowing castable for stainless steel ladles, which includes the following components by weight percentage:
[0025]
[0026] It is also necessary to add 0.12% dispersible alumina and 5% water of the above-mentioned self-flowing castable during construction;
[0027] During construction, it is necessary to support the mold, inject the self-flowing castable mixed with water and dispersant into the mold, the material can flow through any surface and fill any space, and quickly bond with the original leftover material without vibration and noise , while reducing the labor intensity of workers.
Embodiment 2
[0029] The present invention proposes a special corundum self-flowing castable for stainless steel ladles, which includes the following components by weight percentage:
[0030]
[0031] During construction, it is also necessary to add 0.1% dispersible alumina and 5.5% water of the above-mentioned self-flowing castable;
[0032] During construction, it is necessary to support the mold, inject the self-flowing castable mixed with water and dispersant into the mold, the material can flow through any surface and fill any space, and quickly bond with the original leftover material without vibration and noise , while reducing the labor intensity of workers.
