? 大多數(shù)形狀簡(jiǎn)單、厚實(shí)的氧化鋁磚類(lèi)耐火磚多采用模壓法工藝制造。所謂模壓法(也稱(chēng)半干壓法),就是將含有少量黏結(jié)劑的、具有較粗顆粒與細(xì)粉配比的坯料,放在金屬模型內(nèi),在壓機(jī)上受壓而成型。 對(duì)于耐火磚即模壓成型來(lái)說(shuō),為什么泥料的···

? 石灰豎窯窯襯的耐久性對(duì)窯的不維修運(yùn)行時(shí)間有很大的影響,從而對(duì)窯的生產(chǎn)技術(shù)經(jīng)濟(jì)指標(biāo)也有很大的影響。窯的運(yùn)行時(shí)間越長(zhǎng)產(chǎn)品產(chǎn)量就越大,生產(chǎn)lt灰費(fèi)用就越少。窯襯的使用效果及使用壽命取決于耐火材料的性能和質(zhì)量、窯襯材質(zhì)和結(jié)構(gòu)···

? 近年來(lái),我國(guó)水泥工業(yè)迅猛發(fā)展,大暈固體廢棄物被用作原料、燃料,致使耐火材料所承受的熱應(yīng)力、機(jī)械應(yīng)力和化學(xué)侵蝕大幅度增加,導(dǎo)致回轉(zhuǎn)窯用耐火材料襯里的使用周期縮短,耐火材料消耗增加,大大影響了水泥生產(chǎn)企業(yè)的經(jīng)濟(jì)效益。耐···

? 高鋁磚的性能也與粘土磚一樣,由于化學(xué)成分波動(dòng)大,磚種類(lèi)多,用途廣,其性能按用途和牌號(hào)(GB/T 2988-2012高鋁磚國(guó)家標(biāo)準(zhǔn))也有很大差別,如荷重軟化溫度。一般用途的高鋁磚最低為1420℃,而電爐用高鋁磚最高為1550℃,硅線石磚達(dá)16···

鋼包用不燒磚有鋁鎂磚和鋁鎂碳磚、鎂鋁碳磚。它與燒成磚不同之處是釆用水玻璃或酚醛樹(shù)脂等作結(jié)合劑,成型后經(jīng)低溫處理。該耐火磚在使用過(guò)程中,基質(zhì)中的氧化鋁和氧化鎂形成鋁鎂尖晶石,石墨和樹(shù)脂結(jié)合劑中的碳則形成碳鏈網(wǎng)絡(luò)結(jié)構(gòu),因此···
