当前高炉生产中,炉身下部、炉腰和炉腹部位是炉衬破损最严重的地区,其主要原因:一是受冶炼的渣铁及炉料中存在的碱金属氧化物所产生的化学侵蚀;二是因炉内气流分布不合理,受强大热气流的冲击及热负荷的烧损,引起物理破坏;并且在强大热气流的冲击和热烧损作用下,对耐火材料更促进了化学侵蚀,进而加剧了物理破坏.造成这样破损作用,主要在于炉内热气流分布
The current blast furnace production, the lower part of the furnace body, the waist and the belly area is the lining of the most damaged areas, the main reasons: First, by the smelting of iron and slag in the presence of alkali metal oxides produced by chemical erosion; Due to the unreasonable distribution of the air flow in the furnace, the impact of the strong hot air flow and the burning of the heat load, causing physical damage; moreover, under the effect of the strong hot air flow and the thermal burning damage, the chemical erosion is further promoted to the refractory material, Exacerbated the physical damage caused by such damage, mainly in the furnace hot air distribution
