Preparation method of scouring-resistant high-performance carbon-free brick
The invention provides a preparation method of a scouring-resistant high-performance carbon-free brick. The preparation method of the scouring-resistant high-performance carbon-free brick comprises the following steps: (1) preparing the following components in parts by mass: 50-70 parts of aggregate, 5-10 parts of fine powder and 2-5 parts of a composite binding agent; (2) determining that the aggregate is sub-white corundum, fused white corundum and fused magnesia, and the fine powder is corundum fine powder, spinel micro powder, a-Al2O3 (alumina) micro powder, fused magnesia powder and chemical magnesia powder; (3) determining that the sub-white corundum accounts for 50%, the fused white corundum and the fine powder account for 25% in total, and the fused magnesia and the fine powder account for 4% in total. The preparation method of the erosion-resistant high-performance carbon-free brick provided by the invention has the advantages that the erosion-resistant high-performance carbon-free brick has good oxidation resistance, molten steel erosion resistance and thermal shock stability, so smelting requirements can be met.
本发明提供一种耐冲刷型高性能无碳砖的制备方法。所述耐冲刷型高性能无碳砖的制备方法包括以下步骤：(1).按照质量份数计算来准备：骨料为50‑70份，细粉为5‑10份、复合结合剂2‑5；(2).所述骨料为亚白刚玉、电熔白刚玉和电熔镁砂，所述细粉为刚玉细粉、尖晶石微粉、a‑Al2O3(氧化铝)微粉、电熔镁砂份粉和化工氧化镁粉；(3).所述亚白刚玉占比为50％，所述电熔白刚玉和细粉占比一共为25％，所述电熔镁砂和细粉占比一共为4％。本发明提供的耐冲刷型高性能无碳砖的制备方法具有具有良好的抗氧化性能、抗钢水冲刷性及热震稳定性能，致使可以满足冶炼需求的优点。
