Nanopore blast furnace carbon brick and preparation method thereof
The invention discloses a nanopore blast furnace carbon brick which is characterized by comprising the following raw materials in parts by weight: 1-2 parts of graphene alcohol dispersion liquid or aqueous graphene slurry, 55-67 parts of electrically calcined coal aggregate particles, 20-30 parts of graphite crushed aggregate particles, 4-8 parts of silicon powder, 2-5 parts of alumina powder and resin, the preparation method comprises the following steps: S1, preparing a graphene alcohol dispersion liquid or aqueous graphene slurry, and mixing raw materials to prepare a paste material; s2, pressing and curing the paste to obtain a green brick; and S3, loading the green brick into a ring type roasting furnace for high-temperature roasting, and removing burrs to obtain the finished product nano-pore blast furnace carbon brick. The graphene is added, and the modified phenolic resin is matched for use, so that the defect that the grade of micro pores in the existing ultra-microporous blast furnace carbon brick only stays at the micron grade is overcome, and the ultra-microporous blast furnace carbon brick has the characteristics of high micro pore index, high molten iron corrosion resistance, high thermal conductivity and high compressive strength.
本发明公开了一种纳米孔高炉炭砖，其特征在于，包括以下重量份的原料：石墨烯醇类分散液或水性石墨烯浆料1‑2份，电煅煤骨料颗粒55‑67份、石墨碎骨料颗粒20‑30份、硅粉4‑8份、氧化铝粉2‑5份，树脂；制备方法包括：S1、制备石墨烯醇类分散液或水性石墨烯浆料，将原材料混合制得糊料；S2、将糊料进行压制固化得到砖坯；S3、将砖坯装入环式焙烧炉中进行高温焙烧，去毛刺后得到成品纳米孔高炉炭砖；本发明加入了石墨烯，配套使用改性酚醛树脂，已解决现有超微孔高炉炭砖中微小气孔的级别大多只停留在微米级别的缺点，具有高微气孔指标、高抗铁水溶蚀性、高导热性以及高抗压强度的特点。
