??? 堿性耐火磚挖補(bǔ)主要指鎂鉻磚和尖晶石磚的挖補(bǔ)。其在修補(bǔ)時(shí)應(yīng)該注意以下幾個(gè)方面的問題。1)補(bǔ)耐火磚必須采用與舊磚相同廠家相同批次的磚;2)盡可能使用與舊磚同一次檢修的剩余散磚(注:受潮或摔損的磚嚴(yán)禁使用);3)新老磚的接觸···

加熱爐爐體的砌耐火磚規(guī)格及尺寸應(yīng)按磚的尺寸加灰縫厚度來計(jì)算。在設(shè)計(jì)中耐火磚砌體的垂直砌筑尺寸為68mm的倍數(shù);水平砌筑尺寸為116mm的倍數(shù)。由爐子各部位要求的灰縫不同及耐火磚本身存在公差所產(chǎn)生的誤差,可通過加人T-l、T-Z、T-4等···
