High-thermal-conductivity microporous molded carbon brick and preparation method thereof
The invention discloses a high-thermal-conductivity microporous molded carbon brick and a preparation method thereof. The carbon brick is prepared from the following raw materials in parts by weight: 10 to 15 parts of aggregate electrically calcined anthracite fine powder, 35 to 45 parts of aggregate electrically calcined anthracite particles, 12 to 18 parts of alpha-Al2O3 micro powder, 10 to 14 parts of silicon powder, 3 to 6 parts of aluminum-titanium alloy powder, 15 to 18 parts of natural graphite and 15 to 20 parts of binding agent. The binder thermosetting phenolic resin and the silicon powder are modified, so that the prepared carbon brick has good high-temperature-resistant strength, mechanical strength and microporosity, high heat conductivity coefficient and good molten iron corrosion resistance.
本发明公开了一种高导热微孔模压炭砖及其制备方法，所述炭砖包括如下重量份数的原料：骨料电煅无烟煤细粉10‑15份、骨料电煅无烟煤颗粒35‑45份、α‑Al2O3微粉12‑18份、硅粉10‑14份、铝钛合金粉3‑6份、天然石墨15‑18份和结合剂15‑20份；通过对结合剂热固性酚醛树脂和硅粉进行改性，使得本发明制备所得的炭砖具有良好的耐高温强度、力学强度和微孔化率、高的导热系数和良好的抗铁水侵蚀性能。
