使吹煉初期平穩(wěn)升溫，有利于石灰的溶解促進(jìn)成渣。生鐵塊的熔于輕廢鋼，熱容大于輕廢鋼，在廢鋼量后，也是以生鐵塊為主。但生鐵塊加入量過(guò)大后，由于在冶煉前期處于溫度較低狀態(tài)，石灰及廢鋼熔化速度慢，而冶煉冷料加入量，處于化渣的w(FeO)不能及時(shí)充分補(bǔ)充，極易生成高熔點(diǎn)的2CaOSiO2，將未熔化的鐵塊包，鐵塊中的碳的反應(yīng)。廢鋼后，如果加入輕廢鋼過(guò)多，不*在裝鐵時(shí)爐口容易冒。鎂砂中方鎂石晶粒大時(shí)耐侵蝕性好,方鎂石晶粒小時(shí),由于礦渣從大量的晶界侵潤(rùn),易于破損,鎂砂向爐渣中熔出,耐侵蝕性差;另外,加入金屬添加物可抗侵蝕性。對(duì)鎂砂的方鎂石粒徑和金屬添加物對(duì)MgO-C磚抗?fàn)t渣侵蝕性影響研究顯示,加入少量金屬添加物能MgO-C磚的抗侵蝕性,控制鎂砂細(xì)粉粒度有助于抗渣性。2氧化損毀石墨難以被熔渣,渣向磚內(nèi),能抗侵蝕性,但易氧化是其重大缺點(diǎn)。石墨的氧化主要體現(xiàn)為:與O2和CO2的氣體氧化、與熔渣中的鐵氧化物等的氧化和與MgO的反應(yīng)。氣相反應(yīng)主要是由于出鋼后冷卻或待機(jī)修襯等中卷入空氣,使氧氣分壓較高而發(fā)生碳的氧化。在磚表面附有爐渣,有助于保護(hù)石墨被氧化,有人研究在1000℃以上磚表面掛有爐渣對(duì)石墨的防氧化效果明顯。烏魯木齊大口徑耐熱鋼哪里好克州不銹鋼耐熱鋼批發(fā)；</p><div
