Sulfur-resistant magnesium aluminate spinel brick for cement kiln firing zone and method
The invention provides a sulfur-resistant magnesium aluminate spinel brick for a cement kiln firing zone and a method. The preparation method of the sulfur-resistant magnesium aluminate spinel brick for the cement kiln firing zone comprises the following steps: S1, mixing magnesium aluminate spinel particles, magnesium aluminate spinel micro powder, high-purity seawater magnesium oxide micro powder, silica fume, antique bluestone particles, a binding agent, an additive and water to obtain a mixed material; and S2, carrying out compression molding on the mixed material to obtain a brick blank, demolding the brick blank, and carrying out wet curing to make the brick blank achieve final solidification. According to the sulfur-resistant magnesium aluminate spinel brick for the cement kiln firing zone and the method provided by the invention, by increasing the content of the cordierite with a low thermal expansion coefficient, the thermal shock resistance factor of the castable is improved, so that the thermal shock resistance is obviously improved, and by selecting the high-purity seawater magnesium oxide, the sulfur resistance can be enhanced.
本发明提供一种水泥窑烧成带用抗硫镁铝尖晶石砖及方法。所述水泥窑烧成带用抗硫镁铝尖晶石砖制备方法包括以下步骤：S1.将镁铝尖晶石颗粒、镁铝尖晶石微粉、高纯度海水氧化镁微粉、硅灰、董青石颗粒、结合剂、外加剂和水进行混合，得到混料；S2.将混料进行压制成型，得到砖胚，然后对砖胚进行脱模，进行潮湿养护，使得砖胚达到終凝。本发明提供的水泥窑烧成带用抗硫镁铝尖晶石砖及方法通过增加低热膨胀系数的堇青石的含量，提高了浇注料的抗热震因子，使得抗热震性得到明显改善，并且通过选用高纯度海水氧化镁，使得可以加强抗硫性的优点。
