Magnesia carbon brick for hot spot slag line area of blast-age electric furnace as well as preparation method and application of magnesia carbon brick
The invention belongs to the field of refractory materials, and relates to a magnesia carbon brick for a hot-spot slag line area of a blast-age electric furnace and a preparation method and application of the magnesia carbon brick. The magnesia carbon brick for the hot spot slag line area of the electric furnace comprises the following raw materials in parts by weight: 22-27 parts of macrocrystalline fused magnesite with the particle size being more than 3mm and less than or equal to 5mm; 27-32 parts of macrocrystalline fused magnesite with the particle size being more than 1 mm and less than or equal to 3 mm; 15-19 parts of macrocrystalline fused magnesite with the particle size of less than or equal to 1mm; 9-19 parts of macrocrystalline fused magnesite fine powder; 6 to 15 parts of flaky graphite; the flaky graphite is composed of-196 flaky graphite and + 196 flaky graphite; 0.2-4 parts of a first additive; the first additive is composed of titanium carbide powder and boron carbide powder; and 2-3 parts of a binding agent. The magnesia carbon brick is prepared from macrocrystalline fused magnesia, flaky graphite, titanium carbide powder, boron carbide powder, a binder and other raw materials, and has the characteristics of strong slag resistance, good volume stability and long service life.
本发明属于耐火材料领域，涉及一种高炉龄电炉热点渣线区域用镁碳砖及其制备方法与应用。电炉热点渣线区域用镁碳砖包括如下重量份数的原料：3mm﹤粒度≤5mm的大结晶电熔镁砂22‑27份；1mm﹤粒度≤3mm的大结晶电熔镁砂27‑32份；粒度≤1mm的大结晶电熔镁砂15‑19份；大结晶电熔镁砂细粉9‑19份；鳞片状石墨6‑15份；所述鳞片状石墨由‑196鳞片状石墨和+196鳞片状石墨组成；第一添加剂0.2‑4份；所述第一添加剂由碳化钛粉和碳化硼粉组成；结合剂2‑3份。本发明镁碳砖由大结晶电熔镁砂、鳞片状石墨、碳化钛粉、碳化硼粉、结合剂等原料制备而成，具有抗渣性强、体积稳定性好、使用寿命高的特点。
