Method for preparing corundum-magnesium aluminate spinel refractory castable by combining polylactic acid, aluminum oxide and magnesia
The invention provides a preparation method of a corundum-magnesium aluminate spinel refractory castable by combining polylactic acid, aluminum oxide and magnesia. The preparation method of the corundum-magnesium aluminate spinel refractory castable combining the polylactic acid, the aluminum oxide and the magnesia comprises the following steps: S1, preparing raw materials: (1) preparing magnesium aluminate spinel, MgO (magnesium oxide), Al2O3 (aluminum oxide) and [C3H4O2] N (polyacrylic acid); s2, a preparation process: (1) putting all the raw materials into a ball milling tank for dry mixing for 24 hours according to the molar ratio of [C3H4O2] N, Al2O3 and MgO prepared in the step S1 being 1: 1: 2 and the molar fractions of matrix materials ([C3H4O2] N, Al2O3 + MgO) being 20%, 20% and 90%, and then adding water which accounts for 5% of the mass of a solid material as a binding agent; the preparation method of the corundum-magnesium aluminate spinel refractory castable combining the polylactic acid, the aluminum oxide and the magnesia has the advantages that the linear change rate and the apparent porosity can be enhanced, so that the linear change rate and the apparent porosity can be checked.
本发明提供一种利用聚乳酸、氧化铝及含镁砂结合的刚玉‑镁铝尖晶石耐火浇注料制备方法。所述利用聚乳酸、氧化铝及含镁砂结合的刚玉‑镁铝尖晶石耐火浇注料制备方法包括以下步骤：S1、原料：(1)：镁铝尖晶石、MgO(氧化镁)、Al2O3(氧化铝)和[C3H4O2]N(聚丙烯酸)；S2、制备工序：(1).将上述S1中准备的[C3H4O2]N、Al2O3和MgO的摩尔比均为1:1:2，基质料([C3H4O2]N、Al2O3+MgO)的摩尔分数为20％、20％和90％，将所有原料放置到球磨罐中干混24h，然后在加入固体料质量的5％的水作为结合剂。本发明提供的利用聚乳酸、氧化铝及含镁砂结合的刚玉‑镁铝尖晶石耐火浇注料制备方法具有可以加强线性变化率和显气孔率，使得可以来对线性变化率和显气孔率进行查看的优点。
