Ladle brick with high slag corrosion resistance and preparation method thereof
The invention particularly relates to a ladle brick with high slag corrosion resistance and a preparation method thereof, and belongs to the technical field of refractory materials. The ladle brick comprises a component A, and the component A comprises the following substances in percentage by weight: 30-60% of flint clay, 10-30% of andalusite, 5-10% of aluminum-rich spinel, 6-16% of silicon carbide, 1-8% of a sintering aid, and 1-4% of an antioxidant. The ladle brick has the advantages that the density is high; the porosity is low, the strength is high, and the slag corrosion resistant performance is strong. Under the conditions of the same temperature and slag iron erosion, the thickness of an erosion layer and an oxidation layer of the high-erosion-resistance brick is only 1/5-1/3 of that of a traditional ladle brick, so that the service life of a ladle can be greatly prolonged, safety accidents such as iron leakage caused by slag erosion and brick stripping are prevented, and the brick is particularly suitable for ladles, which have a high KR desulfurization rate and can recover desulfurized slag iron.
本发明特别涉及一种高抗渣侵蚀铁水包用砖及制备方法，属于耐火材料技术领域，该铁水包用砖包括组分A，所述组分A由如下质量分数的物质组成：焦宝石30‑60％，红柱石10‑30％，富铝尖晶石5‑10％，碳化硅6‑16％，助烧剂1‑8％，抗氧化剂1‑4％。本发明实施例提供的高抗渣侵蚀铁水包用砖具有致密度高，气孔率低，高强度、高抗渣侵蚀等特点，在同等的温度及渣铁侵蚀条件下，高抗侵蚀砖的侵蚀层和氧化层厚度仅为传统铁包砖的1/5‑1/3，因此能较大幅度的提供铁水包寿命，防止因渣侵蚀和砖剥落产生的漏铁等安全事故，特别适用于KR脱硫率高和需要回收脱硫渣铁的铁水包。
