Reconstructing Dry Blast Furnace

الوصف

Reconstructing Dry Blast Furnace: A new anti-explosive and fast-baking castable refractory is developed and applied for reconstructing the whole trough of a blast furnace **0M3 with single taphole, while the main trough is reconstructed as iron store structure. After *9 days of continuous using and iron pass amount over *****0 tons, the first repairing is taken and the repairing time takes about *2 hrs and the fast heat-up time is only 1 hr around. The result shows that, by using the new technology, the much more long-term life of trough can be gained and the environment of the front platform of the BF with single taphole can be revolutionary improved. The technology is now successfully applied to over *0 troughs which were dry style and all rammed with traditional ASC ramming refractory.
