Example Embodiment
[0028] Example one:
[0029] (1) Weigh the raw materials according to the following ratio:
[0030] Coke 2~0㎜ 16%
[0031] Super high aluminum material 3~1㎜ 10%
[0032] Super high aluminum material 1~0㎜ 5%
[0033] Brown corundum ≤0.088㎜ 5%
[0034] Silicon carbide (90#) 1~0㎜ 10%
[0035] Silicon carbide (90#) ≤0.088㎜ 10%
[0036] Guangxi clay ≤0.088㎜ 16%
[0037] High temperature asphalt ≤0.088㎜ 8%
[0038] Sericite ≤0.088㎜ 10%
[0039] Refined quartz sand 40~70 mesh 10%
[0040] Resin (liquid) 3%
[0041] Tar (mixed tar and anthracene oil) Proportion 1.15~1.16 13%
[0042] (2) Weigh the above solid powder in proportion, then pour it into a heated mixer for dry mixing for 5 minutes, then add the liquid binder (first add the resin, and then add the tar or mixed oil), and mix 40 Minutes, then take the mud to make the Marsha value. If the Marsha value is higher than 1MPa, increase the oil appropriately until the Marsha value drops below 1MPa, then discharge the material, squeeze the mud through ...

[0047] Brown corundum 1~0㎜ 5%
[0048] Brown corundum ≤0.088㎜ 5%
[0049] Silicon carbide (90#) 1~0㎜ 10%
[0050] Silicon carbide (90#) ≤0.088㎜ 10%
[0051] Guangxi clay ≤0.088㎜ 16%
[0052] High temperature asphalt ≤0.088㎜ 8%
[0053] Sericite ≤0.088㎜ 10%
[0054] Refined quartz sand 40~70 mesh 10%
[0055] Resin (liquid) 3%
[0056] Tar (mixed tar and anthracene oil) Proportion 1.15~1.16 13%
[0057] (2) Weigh the above solid powder in proportion, then pour it into a heated mixer for dry mixing for 5 minutes, then add the liquid binder (first add the resin, and then add the tar or mixed oil), and mix 40 Minutes (rotating speed is 14 rpm), and then take the mud to make the Marcia value. If the Marcia value is higher than 1MPa, increase the oil appropriately until the Marcia value drops below 1MPa, then discharge the material and ...

[0062] Brown corundum 1~0㎜ 5%
[0063] Brown corundum ≤0.088㎜ 5%
[0064] Silicon carbide (90#) 1~0㎜ 10%
[0065] Silicon carbide (94#) ≤0.088㎜ 10%
[0066] Guangxi clay ≤0.088㎜ 16%
[0067] High temperature asphalt ≤0.088㎜ 8%
[0068] Sericite ≤0.088㎜ 10%
[0069] Refined quartz sand 40~70 mesh 10%
[0070] Resin (liquid) 3%
