High-strength wear-resistant refractory brick and preparation method thereof
The invention provides a high-strength wear-resistant refractory brick and a preparation method thereof. The high-strength wear-resistant refractory brick is prepared from secondary high-aluminum particle aggregate, sub-white corundum particles, electric porcelain particles, electric porcelain powder, raw aluminum powder and a binding agent. The preparation method comprises the following steps: (1) crushing and screening secondary high-aluminum and sub-white corundum; (2) mixing the electric porcelain particles with superior high-aluminum powder, and grinding into co-ground powder; (3) mixingthe co-ground powder with secondary high-aluminum and sub-white corundum particles to prepare a mixture; (4) mixing the mixture with the binding agent to prepare a mixed material; (5) pressing the mixed material into a green brick; and (6) drying the green brick, putting the green brick into a kiln, and sintering at the temperature of 1450 DEG C to obtain the finished product. Compared with a traditional refractory product, the high-strength wear-resistant refractory brick has the advantages that the strength and the wear resistance are greatly improved; the high-strength wear-resistant refractory brick is quite suitable for being used in parts, with serious gathered flushing wear, of kilns such as a circulating fluidized bed boiler and a fluidized bed furnace.
本发明提供一种高强度耐磨耐火砖及其制备方法。所述高强度耐磨耐火砖由二级高铝颗粒骨料、亚白刚玉颗粒、电瓷颗粒、电瓷粉、生铝粉、结合剂制成。制备方法包括以下步骤：(1)二级高铝、亚白刚玉破碎筛分；(2)电瓷颗粒与上生铝粉混合，研磨成共磨粉；(3)共磨粉与二级高铝、亚白刚玉颗粒混合，制成混合料；(4)混合料与结合剂混炼，制成混炼料；(5)混炼料压制成砖坯；(6)砖坯烘干后，入窑，1450℃烧结，即得成品。发明的高强度耐磨耐火砖与传动的耐火制品相比，其强度、耐磨性都比传统的耐火制品有了很大的提高，非常适合于循环流床锅炉、沸腾炉等窑炉汇总冲涮磨损严重的部位使用。
