Calcium zirconate carbon brick
The invention discloses a calcium zirconate carbon brick, belonging to the technical field of refractory materials. The calcium zirconate carbon brick comprises the following raw materials by weight: 50%-90% of a calcium zirconate material, 0%-40% of a zirconia material, 8%-15% of a carbon material, 0.5%-5% of an antioxidant, and 2%-4% of a binder. The calcium zirconate carbon brick has excellent molten steel erosion resistance, acid slag resistance, thermal shock resistance and oxidation resistance. When steel types such as tire cord steel and spring steel are smelted, the brick serving as a lining of a steel ladle and a tundish has the characteristics of no pollution to molten steel and quite long service life.
本发明公开了一种锆酸钙碳砖，涉及耐火材料技术领域，包括按重量百分数计的如下原料：锆酸钙材料50%～90%，氧化锆材料0%～40%，碳类材料8%～15%，抗氧化剂0.5%～5%、结合剂2%～4%。该锆酸钙碳砖在抗钢水侵蚀、抗酸性渣、抗热震和抗氧化性能是极佳的。它在冶炼帘线钢、弹簧钢等钢种时作为钢包、中间包内衬用砖具有不污染钢水，而且寿命相当长的特点。
