Low-carbon magnesium-calcium steel ladle sliding plate brick and preparation method thereof
The invention discloses a low-carbon magnesium-calcium steel ladle sliding plate brick and a preparation method thereof. The sliding plate brick comprises the following components in percentage by weight: 50%-60% of magnesia-calcium sand, 10%-15% of calcium hexaluminate and 30%-35% of co-grinding powder, 3%-5% of an organic silicon resin binding agent is additionally added; wherein the co-grinding powder is prepared by uniformly mixing 9.5%-19% of magnesia-calcium clinker fine powder, 0.5%-1.5% of silicon carbide fine powder, 8%-10% of aluminum powder, 1%-2% of silicon powder and 5% of alpha-Al2O3 micro powder; the calcium hexaluminate particles are treated by the following steps: stirring the calcium hexaluminate particles and a coating agent solution, and adding 0.5-1.5% of a coating agent on the basis of the total mass of the calcium hexaluminate particles; the main component of the coating agent is nano silicon dioxide, a coating agent solution is alkalescent, the coating temperature is 25-40 DEG C, and the stirring time is 2-4 hours, so that calcium hexaluminate particles with the surfaces coated with silicon dioxide are obtained.
本发明公开了一种低碳镁钙质钢包滑板砖及其制备方法。该滑板砖组成成分及重量百分比为：镁钙砂50％～60％、六铝酸钙10％～15％、共磨粉30％～35％；外加有机硅树脂结合剂3％～5％；其中所述的共磨粉由镁钙砂细粉9.5％～19％、碳化硅细粉0.5％～1.5％、铝粉8％～10％、硅粉1％～2％、α‑Al2O3微粉5％混合均匀制得；所述六铝酸钙颗粒经过以下处理：将六铝酸钙颗粒与包覆剂溶液进行搅拌，以六铝酸钙颗粒总质量为基准，其中加入包覆剂的比例为0.5～1.5％；所述包覆剂的主要成分为纳米二氧化硅，包覆剂溶液呈弱碱性，包覆温度为25～40℃，搅拌时间2～4h，得到表面包覆有二氧化硅的六铝酸钙颗粒。
