我厂50m~3高炉内衬过去采用粘土砖、高铝砖砌筑。一、二年需要大修一次,既花费大量资金,又影响生产。1980年大修时,炉体结构设计为炭捣、高铝砖综合炉底,炉缸以上至炉身下部为全炭捣内衬,采用中温炭捣施工。炭捣料由焦粉(C82%以上,粒度0.5～5mm);煤焦油(15%)和沥青(5%,粒度0.5～3mm)组成。施工方法为:焦粉加温脱去水份,煤焦油煎熬完全去掉水份。当焦油升温至200℃左右,每批称量100kg,先加沥青粉拌和,然后加煤 I plant 50m ~ 3 lining the past with clay brick, high alumina brick masonry. One or two years need overhaul, both cost a lot of money, but also affect the production. Overhaul in 1980, the furnace structure designed for carbon pound, high alumina brick comprehensive bottom, above the hearth to the lower part of the furnace for the entire carbon ramming lined with carbon temperature in the construction. Carbon ramming material consists of coke powder (C82%, particle size 0.5 ~ 5mm); coal tar (15%) and pitch (5%, particle size 0.5 ~ 3mm). Construction methods: coke powder to remove moisture, coal tarry completely remove the water. When the tar warmed to about 200 ℃, weighing 100kg each batch, first add asphalt mixing, and then add coal
