Composition and forming method of composite magnesia carbon brick resistant to high-oxygen slag scouring
The invention discloses a composition and a forming method of a composite magnesia carbon brick resistant to high-oxygen slag scouring, and particularly relates to the technical field of magnesia carbon bricks. The composite magnesia carbon brick comprises an original magnesia carbon brick and an antioxidant part, wherein the original magnesia carbon brick comprises the following components in parts by weight: 65-75 parts of fused magnesia particles, 10-25 parts of fused magnesia fine powder, 10-18 parts of a carbon raw material, 10-20 parts of flaky graphite, and 2-4 parts of a binding agent. The original magnesia carbon brick and the antioxidant part are characterized in that the original magnesia carbon brick comprises the following components in parts by weight: 65-75 parts of fused magnesia particles. The oxidation resistance of the magnesia carbon brick is improved when the magnesia carbon brick is in contact with molten steel and slag in the production and manufacturing process of the magnesia carbon brick, the service life of the magnesia carbon brick is prolonged on the basis of original magnesia-carbon conversion production, the magnesia carbon brick is coated with an oxidation-resistant coating, and an oxidation-resistant material permeates into the magnesia carbon brick, so that the oxidation resistance of the magnesia carbon brick is improved, the high temperature resistance and the hardness of the magnesia carbon brick are improved, the cracking of the magnesia carbon brick is reduced, and batch production can be realized.
本发明公开一种耐高氧熔渣冲刷的复合镁碳砖组成及成型方法，具体涉及镁碳砖技术领域，包括原有镁碳砖和抗氧化部分，原有镁碳砖包括以下成分及其重量份：电熔镁砂颗粒65‑75份，电熔镁砂细粉10‑25份，碳原料10‑18份，鳞片状石墨10‑20份，结合剂2‑4份原有镁碳砖和抗氧化部分，其特征在于，原有镁碳砖包括以下成分及其重量份：电熔镁砂颗粒65‑75份。本发明在对镁碳砖生产制造过程中在对镁碳砖在与钢水和熔渣接触时耐氧化性有所提升，在原有的镁碳转生产的基础上增加镁碳砖的使用寿命，在镁碳砖外部涂有耐氧化涂层，并使耐氧化的材料渗入到镁碳砖的内部，提高镁碳砖的耐氧化性能，并且提高了其耐高温和硬度，减少镁碳砖开裂，可进行批量成产。
