Super-wear-resistant corrosion-resistant furnace lining brick
The invention discloses a super-wear-resistant corrosion-resistant furnace lining brick, and the furnace lining brick is mainly prepared from the following materials in parts by mass: 35-40 parts of magnesium aluminate spinel, 15-25 parts of fused magnesite particles, 5-10 parts of fused magnesite fine powder, 1.2-2.0 parts of tar, 2-6 parts of modified graphite, 0.5-2.0 parts of aluminum-magnesium alloy powder, 5-7 parts of phenolic resin, 0.2-0.5 part of diatom ooze and 1-5 parts of a magnesium-aluminum adhesive. The preparation method of the steel ladle refractory material comprises the steps of burdening, mixing, forming and tunnel drying treatment, wherein in the mixing step, aggregate needs to be fully mixed, then a mixture of tar and modified graphite is added in batches, then a small amount of diatom ooze is added multiple times, and finally other additives are added one by one. The steel ladle refractory material has excellent super wear resistance and corrosion resistance, the required forming pressure is smaller than that of a conventional process, and compared with a conventional process, the preparation method can remarkably save energy and reduce consumption.
本发明涉及一种超耐磨耐腐蚀炉衬砖，主要由以质量份数计的以下材料组成：镁铝尖晶石35‑40份、电熔镁砂颗粒15‑25份、电熔镁砂细粉5‑10份、焦油1.2‑2.0份、改性石墨2‑6份、铝镁合金粉0.5‑2.0份、酚醛树脂5‑7份、硅藻泥0.2‑0.5份、镁铝胶黏剂1‑5份；所述钢包耐材的制备方法包括配料、混炼、成型以及隧道干燥处理，其中混炼步骤需要先将骨料充分混炼后分批加入焦油与改性石墨的混合物，再少量多次添加硅藻泥，最后将其余添加剂逐一添加。本发明的钢包耐材具有优异的超耐磨性能及抗腐蚀性能，且所需的成型压力小于常规工艺，制备方法相比传统工艺能够显著的节能降耗。
