Refractory material for ladle slag entrapment prevention, ladle slag entrapment prevention product and preparation method of ladle slag entrapment prevention product
The invention discloses a refractory material for ladle slag entrapment prevention. The refractory material comprises the following chemical components in percentage by mass: 30-40% of corundum, 30%-40% of alumina, 3%-8% of fused magnesia, 10%-20% of magnesium aluminate spinel, 5%-10% of andalusite, 1.5%-4% of alpha-Al2O3 micro powder, 0.25%-2.5% of SiO2 micro powder, 5%-10% of beta-sialon, 1%-3%of desilicated zirconium fine powder, and 1%-3% of aluminate cement. The invention further discloses a steel ladle slag entrapment prevention product and a preparation method thereof. The steel ladleslag entrapment prevention product is good in slag corrosion resistance, the high-temperature breaking strength is high, the breaking strength of the refractory brick is 10MPa-15MPa at 110 DEG C after24h, the breaking strength of the refractory brick is 25MPa-50MPa after 1550 DEG C*3h high-temperature firing, the breaking strength of the refractory brick is 6MPa-10MPa at a high temperature of 1400 DEG C, the refractoriness of the refractory brick is greater than 1700 DEG C, and the actual service life of the refractory brick is greater than 30 furnaces.
