High-strength environment-friendly refractory brick and production process
The invention relates to the technical field of refractory bricks, and discloses a high-strength environment-friendly refractory brick and a production process thereof.The refractory brick takes refractory clay as a main raw material, the content of Al2O3 (%) in the refractory clay is controlled to be 52-57, the content of Fe2o3 (%) is controlled to be 0.9-1.4, the content of CaO + MgO (%) is controlled to be 0.3-0.6, the content of Na2O + K2O (%) is controlled to be 0.3-0.7, and the refractory brick further comprises a binding agent, clay, pyrophyllite and phosphoric acid auxiliary materials. The weight ratios of the auxiliary materials are respectively 1-3%, 5-10%, 2-8% and 2-4% of the refractory clay. By strictly controlling the proportion of all components in the refractory clay as the main raw material of the refractory brick and the proportion of the binding agent, the clay, the pyrophyllite and the phosphoric acid as auxiliary materials, the firing completeness of the refractory brick can be improved, so that the refractory brick still has very high pressure resistance, fracture resistance and deformation resistance under the dual temperature change of normal temperature and high temperature, and the service life of the refractory brick is prolonged. The brick body stability and the service life of the refractory brick can be enhanced, and the generalization performance is better.
本发明涉及耐火砖技术领域，公开了一种高强度环保型耐火砖及生产工艺，所述耐火砖以耐火粘土为主要原料，其中，耐火粘土中Al2O3(％)含量控制在52～57，Fe2o3(％)控制在0.9～1.4，CaO+MgO(％)控制在0.3～0.6，Na2O+K2O(％)控制在0.3～0.7，所述耐火砖还包括结合剂、粘土、叶腊石、磷酸辅料，其各辅料以重量占比分别为耐火粘土的1～3％，5～10％，2～8％，2～4％。本发明通过严格控制耐火砖主要原料耐火粘土中各组分的比例，以及结合剂、粘土、叶腊石、磷酸辅料的比重配比，能够有利于提高耐火砖烧制的完全性，使其在常温与高温的双重温变下，仍具备非常高的抗压、抗折、耐形变性能，能够加强耐火砖的砖体稳定性以及使用寿命，推广性更佳。
