Carbon ramming material for filling blast furnace carbon bricks and preparation method of carbon ramming material
The invention discloses a carbon ramming material for blast furnace carbon brick filling and a preparation method thereof. The carbon ramming material comprises a carbonaceous raw material and environment-friendly coal tar, and the carbonaceous raw material comprises, by mass, 50-60% of flake graphite particles, 10-20% of crystalline flake graphite, 23-28% of graphite powder, 4-7% of flexible graphite and 2-5% of micron-sized aquadag; the mass of the environment-friendly coal tar is 17-19% of the total mass of the carbonaceous raw materials. The preparation method comprises the following steps: mixing flake graphite particles, crystalline flake graphite and graphite powder, adding into coal tar, uniformly stirring, adding flexible graphite and micron-sized aquadag, and uniformly mixing. The carbon ramming material is high in heat conductivity coefficient, good in construction performance and good in compression resilience, when stress changes to cause separation between the material and liners on the two sides to generate gaps, the material rebounds and is effectively and tightly filled in the wide gaps, and it is guaranteed that heat conduction of a blast furnace is smooth and efficient.
本发明公开了一种用于高炉碳砖填充的碳素捣打料及其制备方法。该碳素捣打料包括碳质原料和环保煤焦油，其中：所述碳质原料中，按质量百分比计，包括：片状石墨颗粒50～60％，鳞片石墨10～20％，石墨粉23～28％，柔性石墨4～7％，微米级石墨乳2～5％；所述环保煤焦油质量为碳质原料总质量的17～19％。通过将片状石墨颗粒、鳞片石墨和石墨粉混合后加入煤焦油中搅拌均匀再加入柔性石墨和微米级石墨乳均匀混合制备得到。该碳素捣打料导热系数高、施工性能好、压缩回复性好，当应力改变导致材料与两侧衬体之间脱离产生缝隙时材料产生回弹，有效且紧密的填充在宽缝内，保证高炉的热量传导通畅高效。
