Abstract

The invention relates to a high heat conductive carbon ramming mass and a preparation method thereof. According to the technical scheme of the invention, the high heat conductive carbon ramming mass comprises the raw materials in percentage by weight: 30-45wt% of industrially synthesized graphite with granularity of 1-5mm, 6-22wt% of industrially synthesized graphite with granularity smaller than 0.074mm, 10-30wt% of flake graphite with granularity of 1-5mm, 8-20wt% of high carbon composite micro powder, and 10-15wt% of modified composite thermosetting resin. The preparation method comprises the following steps: stirring the industrially synthesized graphite with granularity of 1-5mm and high carbon composite micro powder at an intermediate speed first; then, adding 5-8wt% of modified composite thermosetting resin, and stirring at an intermediate speed first and then at a high speed; and finally, pouring the balance of raw materials and residual modified composite thermosetting resin, and stirring at a high speed to prepare the high heat conductive carbon ramming mass. The heat conductive carbon ramming mass provided by the invention has the characteristic of easiness in construction; and according to the prepared heat conductive carbon ramming mass, a cooling system of a blast furnace can be used for effectively cooling a brasque, so that the blast furnace operates stably for a long time.

Description

technical field [0001] The invention belongs to the technical field of carbon ramming materials. Specifically relates to a high thermal conductivity carbon ramming material and a preparation method thereof. Background technique [0002] With the continuous development of modern blast furnaces in the direction of large-scale furnace capacity and high-efficiency production, the importance of blast furnace longevity has become increasingly apparent. The improvement of blast furnace masonry technology and masonry materials has put forward higher requirements. The carbon bricks used in masonry have developed from ordinary carbon bricks to microporous carbon bricks, semi-graphite carbon bricks, graphite carbon bricks and ultra-microporous carbon bricks. , there are higher requirements for carbon ramming materials used in conjunction with carbon bricks, [0003] Carbon ramming material for blast furnace is mainly used in the leveling layer of the blast furnace bottom (the ramming...
