High-temperature super-corrosion-resistant steel ladle refractory material and preparation method thereof
The invention relates to a high-temperature super-corrosion-resistant ladle refractory material and a preparation method thereof. The high-temperature super-corrosion-resistant ladle refractory material is mainly prepared from the following materials in parts by mass: 45-55 parts of macrocrystalline fused magnesia, 15-25 parts of fused magnesia particles, 5-10 parts of fused magnesia fine powder,1.2-2.0 parts of carbon black, 3-5 parts of crystalline flake graphite, 0.6-1.5 parts of aluminum-magnesium alloy powder, 5-7 parts of phenolic resin, 0.2-0.5 part of polyethylene wax and 2-4 parts ofa 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 carbon black and crystalline flake graphite is added in batches, then a small amount of polyethylene wax is added multiple times, and finally other additives are added one by one. The steel ladle refractory material has excellent high-temperature resistance and corrosion resistance, the needed 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.
本发明涉及一种高温超耐蚀钢包耐材及其制备方法，主要由以质量份数计的以下材料组成：大结晶电熔镁砂45‑55份、电熔镁砂颗粒15‑25份、电熔镁砂细粉5‑10份、炭黑1.2‑2.0份、鳞片石墨3‑5份、铝镁合金粉0.6‑1.5份、酚醛树脂5‑7份、聚乙烯蜡0.2‑0.5份、镁铝胶黏剂2‑4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炭黑与鳞片石墨的混合物，再少量多次添加聚乙烯蜡，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抗高温性能及抗腐蚀性能，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。
