Electrically fused recombined magnesite-chrome brick, preparation method and application thereof
The invention is applicable to the technical field of refractory materials, and provides an electrically fused recombined magnesite-chrome brick, a preparation method and application thereof. The electrically fused recombined magnesite-chrome brick comprises the following components: fused magnesite-chrome sand, fused magnesite granules, fused magnesite powder and nanoscale chromium oxide powder;and the fused magnesite-chrome sand comprises MgO and Cr2O3. The electrically fused recombined magnesite-chrome brick obtained by the invention has the characteristics of high refractoriness, high strength, good thermal shock resistance, strong erosion resistance and the like; according to the invention, fused magnesite-chrome sand, nanoscale chromium oxide powder and the like are adopted as the raw materials, a uniform network structure with fused magnesite-chrome sand as a main frame and nanoscale chromium oxide powder as meshes can be formed in the product, the structure can effectively solve the long-standing problems of poor erosion resistance and thermal shock resistance stability of the product, and the service life of a smelting furnace can be greatly prolonged when the structure is applied to the smelting furnace.
本发明适用于耐火材料技术领域，提供了一种电熔再结合镁铬砖及其制备方法和应用，该电熔再结合镁铬砖包括以下组分：电熔镁铬砂、电熔镁砂颗粒料、电熔镁砂粉料、纳米级氧化铬粉料；所述电熔镁铬砂包括MgO和Cr2O3。本发明得到的电熔再结合镁铬砖具有耐火度高、强度大、热震稳定性好、抗侵蚀能力强等特点，其通过采用电熔镁铬砂和纳米级氧化铬粉料等作为原料，可以使得制品内部形成以电熔镁铬砂为主架、纳米级氧化铬粉料为网孔的均匀网络状结构，这种结构可有效地解决了该类制品长期以来存在的耐侵蚀和耐热震稳定性差的问题，将其应用于冶炼炉中，可以大大提高冶炼炉的使用寿命。
