High heat conductivity ramming material

The invention discloses a high heat conductivity ramming material which is prepared by raw materials of artificial graphite particles, anthracite and a binder according to the following method: treating the anthracite in a graphitizing furnace for 24 hours at the high temperature; naturally cooling, and crushing; preparing a raw material A by a particle material according to a certain grain size distribution; preparing a raw material B by artificial graphite according to a certain grain size distribution; preparing the binder C by coal tar pitch, coal tar and furan resin at a weight ratio of 20:60:20; mixing the raw material A and the raw material B in a mixing kneading pot at a ratio of 1:1; heating to 80-100 DEG C; adding the binder C, wherein a ratio of dry materials to the binder is 84:16; cooling the mixture after mixing for 1-2 hours; and split charging into bags. With the adoption of the high heat conductivity ramming material, the construction is convenient, the heat-conducting property is good, and the heat surface temperature in a furnace lining can be quickly conducted to the cooling wall. The high heat conductivity ramming material is used for leveling a blast-furnace bottom or filling gaps between a furnace body and a furnace shell, so that the service life of the furnace body can be prolonged by more than two years.
