| titleOfInvention | Magnesium oxide-based filter with multi-pore structure and preparation method thereof |
| abstract | The invention belongs to a magnesium oxide based filter with a multi-pore structure and a preparation method thereof. The technical scheme is as follows: firstly, porous magnesium oxide fine powder, silicon dioxide micropowder, calcium aluminate cement and alpha-Al 2 O 3 Mixing the micro powder and the polycarboxylate, then respectively adding porous magnesium oxide particles with the particle sizes of 1.5-2 mm, 0.5-1.4 mm and 0.1-0.4 mm, uniformly mixing, adding water, stirring, forming, maintaining and demolding to obtain a magnesium oxide-based filter green body with a multi-pore structure; and then drying the magnesium oxide based filter green body with the multiple pore structures, and preserving heat for 2-4.5 hours at 1570-1670 ℃ to obtain the magnesium oxide based filter with the multiple pore structures. The product obtained by the invention has high strength, good thermal shock resistance, long service life, large molten steel flux and the effect of adding MgO and Al in molten steel 2 O 3 And SiO 2 And the adsorption capacity of nonmetallic inclusions is strong. |
