Erosion-resistant and impact-resistant steel ladle working layer castable and preparation method thereof
The invention relates to an erosion-resistant and impact-resistant steel ladle working layer castable and a preparation method thereof. The raw materials comprise 10 to 25 parts of brown fused alumina of 10 to 25 mm, 10 to 25 parts of tabular corundum of 5 to 10 mm, 10 to 20 parts of tabular corundum of 3 to 6 mm, 10 to 15 parts of tabular corundum of 1 to 3 mm, 10 to 20 parts of tabular corundum of 0 to 1 mm, 0 to 10 parts of tabular corundum of 0.074 mm, 10 to 15 parts of sintered alumina-magnesia spinel, 2 to 5 parts of active alpha-Al2O3 powder of 1 mu m, 2 to 5 parts of active alpha-Al2O3 powder of 2.5 mu m, 2 to 5 parts of calcined alpha-Al2O3 powder of 4.5 mu m, 2 to 5 parts of calcined alpha-Al2O3 powder of 6 mu m, 5 to 8 parts of binding agent, 0.5 to 3 parts of chromium metal powder, 0.1 to 0.2 part of water reducing agent and 0.05 to 0.1 part of explosion-proof fiber. The high-temperature breaking strength is high, and the slag corrosion resistance and the impact resistance are excellent.
