High-strength tundish magnesium slag dam plate
The invention discloses a high-strength tundish magnesium slag-stopping weir plate which is formed by pouring a high-durability magnesium castable comprising the following components in percentage by weight: 64-70% of magnesia particles with the particle size of less than or equal to 10mm; 20-28% of fine powder with a particle size of less than or equal to 0.088 mm; 1-3% of corundum with a particle size of not more than 0.5 mm; 2-7% of a magnesium binding agent; 1-3% of silicon oxynitride micro powder; and 0.10%-0.20% of carbon fiber and 0.05%-0.15% of a water reducing agent are additionally added. According to the invention, the defects and deficiencies of the existing weir plate magnesian castable are overcome, and the double requirements that the magnesian weir plate is suitable for longer service life and high-quality steel are met.
本发明公开了一种高强中间包镁质挡渣堰板，按重量百分计，该镁质挡渣堰板由以下组份的高耐用性镁质浇注料浇注而成：粒径≤10mm的镁砂颗粒料：64～70％；粒径≤0.088mm的细粉：20～28％；粒径≤0.5mm的刚玉：1～3％；镁质结合剂：2～7％；氮氧化硅微粉1～3％；以及，外加碳纤维0.10～0.20％和减水剂0.05～0.15％。其克服了现有堰板镁质浇注料的缺陷与不足，达到镁质堰板适合更高的使用寿命与高品质钢的双重需求。
