Long-life tundish slag line dry material
The invention discloses a long-life tundish slag line dry material. The dry material is prepared from, by weight, 60-80 parts of sintered magnesia particles, 20-40 parts of fused magnesia powder, 2.5-4.0 parts of solid resin powder, 2-8 parts of an additive and 0.5-1.5 parts of a sintering agent, and the additive is one or a combination of more of chromium oxide micro powder, zirconium oxide micro powder and aluminum oxide micro powder. The tundish slag line dry material has the beneficial effects that by changing the composition of the tundish slag line dry material, the erosion resistance, the wettability resistance and the scouring resistance are improved, and the loss is reduced, so that the service life of the whole tundish is prolonged.
本发明公开了一种长寿命中间包渣线干式料，由以下重量份的原料制成：烧结镁砂颗粒60－80份、电熔镁砂粉20－40份、固体树脂粉2.5－4.0份、添加剂2－8份、烧结剂0.5－1.5份，添加剂为氧化铬微粉、氧化锆微粉和氧化铝微粉中的一种或多种组合，本发明的有益效果是，通过改变中间包渣线干式料的组成，提高了抗侵蚀性、抗浸润性以及抗冲刷性，降低了损耗，从而提高整个中间包寿命。
