| titleOfInvention | A kind of preparation method of ferro-magnesium-aluminum spinelle coal injection pipe |
| abstract | The present invention relates to a kind of preparation methods of magnesium aluminate spinel coal injection pipe, include the following steps：1. selection prepares the material of ferro-magnesium-aluminum spinelle coal injection pipe, and by the material fragmentation, broken material A is obtained；2. broken material A is screened, then weigh respectively in proportion, pour into agitating device, stir evenly, material B must be stirred；3. adding in additive and water into stirring material B, stir evenly, obtain mixture C；4. mixture C is added in into the mold for making coal injection pipe, until surfacing, obtains coal injection pipe sample；5. coal injection pipe sample and mold are positioned in air, 36 48 hours are stood, is then demoulded, obtains coal injection pipe sample one；6. by one natural curing of coal injection pipe sample 48 60 hours, processing then is dried to coal injection pipe sample, obtains coal injection pipe.The preparation method of the present invention by adjusting granularmetric composition, realize product from stream mode, avoid the construction problem that basie castable is brought. |
