Embodiment 1
[0014] A castable, the use part is the direct lining of the ladle and the molten steel, wherein the weight percentage of each component is: the weight percentage of each component is: sub-white corundum 12-8mm is 15%, sintered microporous aluminum spinel 8 -5mm is 14%, sintered microporous aluminum spinel 5-3mm is 15%, sintered microporous aluminum spinel 3-1mm is 13%, sintered microporous aluminum spinel≤1mm is 30%, carbon dioxide Chromium powder 1%, composite gel powder 5%, hydrated alumina micropowder 1%, pearl clay powder 1%, bismuth germanate powder 0.5%, modified pure calcium aluminate cement 4.5%, plus C 7 h 10 N 2 o 2 S0.1%, C 21 h 14 Na 2 o 6 S 2 0.1%, 2-morpholineethanesulfonic acid 0.05%. Mix the above ingredients evenly to obtain the ladle castable.
[0015] Experimental test was carried out with a castable formula of Example 1: adding 5wt% water accounting for the weight of the above formula, the test performance indicators were as follows: the bulk densi...
Embodiment 2
[0017] A castable, wherein the weight percentage of each component is: the weight percentage of each component is: 14% for sub-white corundum 12-8mm, 15% for sintered microporous aluminum spinel 8-5mm, 15% for sintered microporous aluminum spinel Stone 5-3mm is 15%, sintered microporous aluminum spinel 3-1mm is 12%, sintered microporous aluminum spinel ≤ 1mm is 30%, modified magnesia-calcium sand ≤ 1mm is 2%, and chromium dicarbide Powder 1%, composite gel powder 5%, hydrated alumina powder 1%, pearl clay powder 1%, bismuth germanate powder 0.5%, modified pure calcium aluminate cement 3.5%, plus C 7 h 10 N 2 o 2 S0.1%, C 21 h 14 Na 2 o 6 S 2 0.1%, 2-morpholineethanesulfonic acid 0.05%. Mix the above ingredients evenly to obtain the ladle castable.
[0018] Experimental test was carried out with the castable formula of Example 2: add water accounting for 6wt% of the above formula, and the test performance indicators are as follows: the bulk density is 2.9 / cm 3 The fle...
