氧化锆空心球浇注料的研制 总被引:1,自引:0,他引:1
研究了氧化锆空心球的加入量、m-ZrO2微粉和不同添加剂对浇注料的物理性能的影响。结果表明,氧化锆空心球的加入量有一个较合适的范围。m-ZrO2微粉的引入,不仅可使浇注料有一个较合适的体积密度,又可使其强度提高。两种Mg0-Al2O3系添加剂均能大大提高浇注料的物理性能,并对材料的相组成产生影响,因而能提高其高温使用性能。 相似文献

高纯度的Al2O3-MgO-CaO系浇注料正广泛应用于精炼钢包的透气砖、座砖、工作衬及包壁修补料等,纯铝酸钙水泥既是Al2O3-MgO-CaO系统浇注料的结合剂,同时又是浇注料中CaO的主要来源.本试验通过改变纯铝酸钙水泥的加入量来改变CaO的含量,探究高温下形成的CA6等矿相对体系性能的影响.结果发现:氧化钙以本研究中的纯铝酸水泥形式引入时,随其引入量的增加,材料经110 ℃处理后的物理性能呈现优化的趋势;CA6形成产生的体积膨胀在促进结构的致密化的同时,当达到一定程度时,会导致材料结构劣化,因此材料经1550 ℃处理及5次热循环后,其物理性能呈现先提高后降低的趋势.综合各项性能认为,纯铝酸钙水泥加入量在5wt%~8wt%时其高温强度及抗热震性能较为优异. 相似文献

The influence of iron oxide in the phase relationships of Al2O3-MgO-CaO and Al2O3-MgO purging plug refractory material has been studied by the thermodynamic analysis tool FactSage. Results showed that the system without CaO to be advantageous on the onset temperature of liquid phase, and on the liquid content at defined chemical composition and temperature. Therefore, CaO negatively influences the iron-rich slag resistance of the purging plug material. Analysis of used purging plugs proved the thermodynamic results. They showed that spinel solid solution and calcium hexaluminate as stable phases were formed in the reaction with iron oxide slag.Corundum-spinel castables with and without calcium aluminate cement were investigated in the laboratory to compare the relevant technical properties. In the cement bonded castable, the curing and drying strength are increased by increasing the cement content. However high cement addition requires higher water demand, which results in higher open porosity and a lower hot modulus of rupture (HMoR). In the CaO-free, no-cement castable with hydratable alumina binder, the water demand is slightly higher when compared to the ultra-low cement castable. However, the curing and drying strength are still slightly higher for the no-cement castable. As there is no significant difference in HMoR with various hydratable alumina binder additions, low dosage of such binder in the range of two to four percent is normally recommended to avoid excessive water addition. Cement bonded castables (with CaO) show some advantages to the no-cement castable (non-CaO) regarding HMoR, however the no-cement castable could have advantages regarding the iron-rich slag resistance and thermal shock resistance. 相似文献

Development of high pure alumina castable is studied by using synthesized mullite sol as the sole binder. Mullite sol is prepared by wet chemical route and is characterized by its solid content, particle size, thermal analysis, phase development with temperature, microstructure, etc. This sol is used at two different percentages in high alumina castable compositions with two different particle size distribution patterns. Conventional castable processing is done on the compositions and the characterizations are done after heat treatment at three different temperatures. Finally, the best composition is also compared with the commercially available silica sol containing high alumina castable with similar particle size distribution. Considerably improved hot strength, high corrosion resistance and flexural strength (hot modulus of rupture) are obtained for the mullite sol containing composition but with relatively lower thermal shock resistance. 相似文献
