產(chǎn)品詳情
北京科技大學(xué)的學(xué)者采用座滴法測定固液間接觸角,分別對(duì)鎂碳質(zhì)基片及基片中的兩種主要組元與LF精煉渣之間的潤濕性進(jìn)行了研究,并從潤濕性角度研究了鎂碳磚損毀機(jī)理。研究表明,在精煉溫度下,熔渣對(duì)石墨均呈不潤濕狀態(tài),溫度越低越不容易潤濕。而熔渣對(duì)MgO組元呈完全潤濕狀態(tài)。熔渣與鎂碳質(zhì)基片間的接觸角在溫度為1460~1480℃時(shí)存在明顯轉(zhuǎn)折,在轉(zhuǎn)折點(diǎn)溫度以下,MgO和碳的反應(yīng)受到,熔渣對(duì)基片保持不潤濕狀態(tài)。

分四火鍛造成型,鍛造溫度1250~750℃,變形過程總鍛造比為6.4。鍛后熱處理采用正火+回火。12Cr2Mo1鋼比較理想的組織是貝氏體組織,具有良好的強(qiáng)韌性、組織穩(wěn)定性、耐熱疲勞性,并且比馬氏體組織或鐵素體+珠光體具有更好的抗回火能力。通過SEM、EDS等試驗(yàn)手段對(duì)鋼中夾雜物的大小、形貌、數(shù)量進(jìn)行研究,發(fā)現(xiàn)鋼中夾雜物多為脫氧產(chǎn)物及合金料和耐火材料的氧化產(chǎn)物,主要為硅鋁酸鹽復(fù)合夾雜物。試驗(yàn)表明,12Cr2Mo1鋼的純凈度較高,大于10m的夾雜物約為0.47%。

鉆孔鉆孔首先是要盡可能減少冷作硬化。在鉆孔前,建議不要沖孔,因?yàn)闆_孔會(huì)使鉆孔的表面產(chǎn)生冷作硬化。采用中心鉆,如果不能使用中心鉆,就用樣沖沖中心孔。同樣,當(dāng)使用手動(dòng)進(jìn)給鉆進(jìn)時(shí),要緊的是不能使鉆進(jìn)中斷,而且鉆壓要保持均勻連續(xù)。應(yīng)使用高速鋼麻花鉆,為了防止產(chǎn)生摩擦,鉆頭要保持鋒利,關(guān)于切削角、前角、后隙角和切削速度應(yīng)按制造廠說明。成型絕大多數(shù)成型技術(shù)通用于所有金屬。主要區(qū)別仍是不銹鋼強(qiáng)度更高和它的冷作硬化特性。
