產(chǎn)品詳情
與固體還原劑單獨(dú)燃燒時(shí)相比,與CH4同時(shí)噴吹時(shí)的燃燒氣化率在噴吹粉煤時(shí)為4%,在粉煤和廢塑料同時(shí)噴吹時(shí)可提高5%左右。這是因?yàn)槿紵俣瓤斓臍怏w還原劑CH4在噴吹后就會(huì)立刻著火燃燒,使?fàn)t內(nèi)溫度升高,使粉煤和塑料升溫、揮發(fā),促進(jìn)揮發(fā)份的燃燒和固體成分的燃燒等一系列燃燒氣化反應(yīng)所致。燃燒氣化率的提高可以使未燃粉的發(fā)生量下降,因此這些因素有助于減小爐料在爐缸中心死料柱和爐下部的堆積,避免爐下部透氣性變差。根據(jù)荷重軟化試驗(yàn)就還原氣體中的氫對(duì)燒結(jié)礦還原行為的影響進(jìn)行了調(diào)查。

主要目的是要將鋼水中夾雜物含量減少到程度,促進(jìn)顆粒分離,避免被大氣、爐渣和耐火材料二次氧化等。有害夾雜物一個(gè)主要成因是非常小的夾雜物在紊流區(qū)凝結(jié),這出現(xiàn)在從大包到中間包、中間包再到結(jié)晶器傳輸鋼水的過(guò)程。相反,外來(lái)非金屬夾雜物源于爐渣夾帶,保護(hù)渣絕不能乳化進(jìn)入鋼水。這是對(duì)鋼鐵工業(yè)在這個(gè)艱難冶金領(lǐng)域里繼續(xù)發(fā)展提出的挑戰(zhàn)。2潔凈鋼這次的研究不是要建立潔凈鋼的通用定義,因?yàn)闈崈舳仁卿摬氖褂玫闹苯咏Y(jié)果,對(duì)潔凈度的要求各不相同。
