淄博钢铁厂22m~3高炉热风炉于1985年8月开始采用了陶瓷燃烧器。该燃烧器是采取中心通道供空气,四周通道供煤气,这是由于煤气压力较高的缘故。陶瓷燃烧器采用优质的矾土水泥耐火混凝土制成的,其配比为:①500标号矾土水泥(粒度<0.088mm不少于70%)15%;②特级矾土细粉(粒度<0.88mm不少于85%)15%;③二级矾土熟料块(粒度<5mm)20%;④三级矾土熟料块(粒度5～15mm)50%;⑤外加水量 Zibo Iron and Steel Plant 22m ~ 3 blast furnace stove in August 1985 began using a ceramic burner. The burner is to take the central channel for the air around the channel for gas, which is due to higher gas pressure reasons. The ceramic burner is made of high-quality bauxite cement refractory concrete with the following proportions: ①500% bauxite cement (not less than 70% of particle size <0.088mm) 15%; ② special grade bauxite powder (particle size <0.88mm Not less than 85%) 15%; ③ secondary bauxite clinker block (particle size <5mm) 20%; third bauxite clinker block (particle size 5 ~ 15mm) 50%
