This topic on the basis of four steel rolling plant of masteel 75 t tundish shape size and thin slab production line process parameters, software CFX numerical simulation and water model experiment method, on the shape of the three schemes of current stabilizer is optimized, the optimized tundish current stabilizer in maanshan steel rolling factory of four practical application are obtained. For improving the magnesian tundish current stabilizer using performance, by adding tin oxide, Si02 micro powder, alpha Al2O3 powder, MA spinel powder and magnesia binder, the magnesian tundish current stabilizer composition and the combination of mechanism, this thesis probes into the and get the following conclusions: 1, magnesia binder can be used for magnesia material production, the best addition amount of 2-4%. 2, introducing a small amount of organic fiber tundish current stabilizer can significantly strengthen magnesia material resistance to burst. 3, tin oxide as sintering agent can effectively improve the magnesian tundish current stabilizer in high temperature strength, addition amount of 1% when the effect is better. 2% of silicon powder and 2% magnesia binder mixing, can make the magnesian tundish current stabilizer waterproof performance and show porosity, volume density, flexural strength and compressive strength improved significantly. 4, alpha Al2O3 powder can significantly improve the magnesian tundish of thermal shock resistance of current stabilizer.
