Magnesia carbon brick for converter impact zone and preparation method of magnesia carbon brick
The invention discloses a magnesia carbon brick for a converter impact zone and a preparation method of the magnesia carbon brick. The magnesia carbon brick is prepared from the following raw materials in parts by weight: 10-30 parts of fused magnesite of which the granularity is more than or equal to 3mm and less than 5mm; 20-40 parts of fused magnesite of which the granularity is more than or equal to 1mm and less than 3mm; 10-30 parts of fused magnesite of which the granularity is more than or equal to 0.5 mm and less than 1mm; 10-20 parts of fused magnesite fine powder with a particle sizeof less than 0.0088 mm; 3-6 parts of flake graphite; 1-3 parts of a phenolic resin binder; 1-6 parts of an additive. The additive is composed of four raw materials including resin powder with the particle size being smaller than or equal to 320 meshes, Ni powder, alpha-Al2O3 and steel fibers. The magnesia carbon brick for the converter impact zone prepared from the additive can be highly matchedwith furnace linings of other parts, continuous and stable production of a steel mill is effectively guaranteed, and the magnesia carbon brick has important significance in increasing economic benefits of the steel mill.
本发明公开了一种转炉冲击区用镁碳砖及其制备方法，由下列重量份数的原料构成：3mm≤粒度＜5mm的电熔镁砂10‑30份；1mm≤粒度＜3mm的电熔镁砂20‑40份；0.5mm≤粒度＜1mm的电熔镁砂10‑30份；粒度小于0.0088mm的电熔镁砂细粉10‑20份；鳞片状石墨3‑6份；酚醛树脂结合剂1‑3份；添加剂1‑6份；所述添加剂是由粒级≤320目的树脂粉、Ni粉、α‑Al2O3、钢纤维四种原料构成。本发明通过采用上述添加剂制备的转炉冲击区镁碳砖能够与其它部位炉衬具有较高的匹配度，有效保证了钢厂生产持续稳定进行，对于增加钢厂经济效益具有重要的意义。
