Embodiment 1
[0035] The raw material composition of wear-resistant materials for high-strength blast furnace flushing slag ditch is as follows: by weight percentage, brown corundum 38%; silicon carbide 10%; mullite 15.3%; cement 30%; silicon dioxide micropowder 2%; metal silicon 0.5% ; Aluminum 0.05%; Water reducing agent 0.15%; Steel fiber 4%.
[0036] The preparation method is as follows: put cement, silicon dioxide micropowder, metal silicon, metal aluminum, and water reducing agent into the DSH-1 type double-helix conical mixer according to the above weight percentage and stir evenly to prepare premixed powder; then, premixed powder , brown corundum, silicon carbide, mullite, and steel fiber are put into the JW-350 type forced mixer according to the above weight percentage and stirred evenly, and the wear-resistant material for high-strength blast furnace flushing slag ditch can be obtained.
Embodiment 2
[0038] The raw material composition of wear-resistant materials for high-strength blast furnace flushing slag ditch is as follows: by weight percentage, brown corundum 32.5%; silicon carbide 20%; mullite 10.3%; cement 30%; silicon dioxide micropowder 2%; metal silicon 1% ; Aluminum 0.05%; Water reducing agent 0.15%; Steel fiber 4%.
[0039] The preparation method is the same as in Example 1 to prepare the wear-resistant material for blast furnace flushing slag ditch.
Embodiment 3
[0041] The raw material composition of wear-resistant materials for high-strength blast furnace flushing slag ditch is as follows: by weight percentage, brown corundum 38%; silicon carbide 15%; mullite 10.3%; cement 30%; silica micropowder 2%; metal silicon 0.5% ; Aluminum 0.05%; Water reducing agent 0.15%; Steel fiber 4%.
[0042] The preparation method is the same as in Example 1 to prepare the wear-resistant material for blast furnace flushing slag ditch.
