Environment-friendly high-thermal-conductivity carbon ramming material and preparation method thereof
The invention discloses an environment-friendly high-thermal-conductivity carbon ramming material and a preparation method thereof. The carbon ramming material comprises powder and dimethyl silicone oil, wherein the powder material is prepared from the following components in percentage by mass: 55 to 60 percent of high-power graphite particles, 30 to 35 percent of high-power graphite powder, 5 to 10 percent of spherical graphite, 0.5 to 2 percent of copper powder and 0.5 to 1 percent of conductive carbon black; the mass of the dimethyl silicone oil is 15-20% of the mass of the powder; the preparation method comprises the following steps: adding copper powder and conductive carbon black into dimethyl silicone oil in advance, uniformly dispersing, then adding into a mixture obtained by mixing power graphite particles, spherical graphite and high-power graphite powder, and mixing and grinding. The obtained carbon ramming material has excellent heat-conducting property, the flatness of the ramming material after construction is good, contact between the ramming material and carbon bricks is facilitated, heat of the carbon bricks can be timely and effectively transferred, the service life of a blast furnace is further prolonged, and meanwhile, the carbon ramming material is low in cost and environmentally friendly and has wide application prospects.
本发明公开了一种环保型高导热碳素捣打料及其制备方法。该碳素捣打料包括粉料和二甲基硅油；其中：粉料中，按质量百分比计，包括以下组分：高功率石墨颗粒55‑60％，高功率石墨粉30～35％，球形石墨5～10％，铜粉0.5～2％，导电炭黑0.5‑1％；所述二甲基硅油质量为所述粉料质量的15～20％；预先将铜粉和导电炭黑加入到二甲基硅油中分散均匀，然后加入到功率石墨颗粒、球形石墨、高功率石墨粉混合得到混合料中混碾制备得到。所得碳素捣打料具有优异的导热性能，施工后的捣打料平整度良好，有利于捣打料与碳砖之间接触，能够及时有效地传递碳砖热量，进而延长高炉的使用寿命，同时成本低，环境友好，具有广泛的应用前景。
