    合金元素鈮、鉭、硼、稀土元素在耐熱鋼中的作用?

    友利通達(dá)金屬(天津)有限公司常年經(jīng)營(yíng)天津冶金軋一鋼鐵集團(tuán)、包頭鋼鐵集團(tuán)、河北港陸、天津北方鋼板、天津天鐵、濟(jì)鋼,太鋼,唐鋼.舞鋼等多家鋼廠生產(chǎn)的耐磨板,耐磨鋼板,400耐磨板,65MN鋼板,65MN彈簧鋼板,35CRMO合金板,尋甸板,40CR合金板,42CRMO合金板,15CRMO合金板,12cr1mov合金板等多種鋼板。


    鈮也是強(qiáng)碳化物形成元素,鈮的碳化物在高溫下十分穩(wěn)定,只比鈦的碳化物略為遜色。由于鈮具有良好的熱強(qiáng)性,因此,鈮在低合金耐熱鋼和高合金耐熱鋼中都獲得了廣泛的應(yīng)用。含鈮的多元合金化的珠光體低合金耐熱鋼在蒸汽發(fā)電機(jī)中的使用溫度可達(dá)550℃。鈮在含鉻為12%的耐熱鋼中獲得應(yīng)用,提高了鋼的熱強(qiáng)性。

     鉭與鈮在元素周期表中為同族,鉭在耐熱鋼中的作用與鈮類同。由于鉭的價(jià)格昂貴,在一般耐熱鋼中基本不加鉭,但通常隨鋼中加鈮時(shí)帶入。通常只在鑄造高溫合金中加鉭。



     硼吸附在奧氏體晶界上,降低了晶間的能量,阻抑鐵素體晶核的形成,因而延長(zhǎng)了先共析鐵素體和上貝氏體轉(zhuǎn)變的孕育期,硼只有以固溶形式存在于鋼中才能起到有教作用。當(dāng)硼與鋼中殘留的氮、氧化合形成穩(wěn)定的夾雜物時(shí),反而對(duì)鋼的性能有不利的作用。在珠光體耐熱鋼中,微量硼可以提高鋼的高溫強(qiáng)度;在奧氏體耐熱鋼中加入0.025%B可以提高其抗蠕變性能,但硼含量較高時(shí),其作用相反。加入硼強(qiáng)化晶界對(duì)增強(qiáng)耐熱鋼的持久強(qiáng)度十分重要。

    稀土元素的氧化物可以增加基體金屬與氧化膜之間的附著力,因?yàn)橄⊥裂趸飳?duì)基體金屬有%26ldquo;釘扎%26rdquo;作用。稀土金屬鑭和能降低Cr 2O3的揮發(fā)性,改善氧化物的組成,變成更加穩(wěn)定的(Cr、La)2O3氧化物膜、鑭抑制在1100~1200℃范圍內(nèi)形成易分解的NiO膜。稀土元素也是鋼中很好的脫硫去氣劑,可以清除其他(如、銻、鉍等)有害雜質(zhì),可以改善鋼中夾雜物的形狀和分布狀態(tài),從而改善和提高鋼的質(zhì)量和耐熱性能。


    友利通達(dá)金屬(天津)有限公司主要代理經(jīng)營(yíng):成都、寶鋼、冶鋼、衡陽(yáng)、包頭、鞍山、天津、洪鋼、無錫、聊城、規(guī)格耐磨板,中厚壁鋼板,主營(yíng):NM360耐磨板,NM400耐磨板,NM450耐磨板,NM500耐磨板,NM550耐磨板,NM600耐磨板,q690板材,高強(qiáng)板,耐候板,合金板,不銹鋼板,高錳耐磨板,橋梁板,寶鋼MN13并與既大鋼廠建立起扎實(shí)的業(yè)務(wù)關(guān)系。
