1.爐內(nèi)投入法: 增碳劑適于在感應(yīng)爐中熔煉使用，但依據(jù)工藝要求具體使用也不盡相同。 (1) 在中頻電爐熔煉中使用增碳劑，可按配比或碳當(dāng)量要求隨料加入電爐中下部位，回收率可達(dá)95%以上; (2) 如果碳量不足調(diào)整碳分時(shí)，先打凈爐中熔渣，再加增碳劑，通過鐵液升溫，河南石墨增碳劑，電磁攪拌或人工攪拌使碳溶解吸收，河南石墨增碳劑，回收率可在90%左右，如果采用低溫增碳工藝，即爐料只熔化一部分，熔化的鐵液溫度較低的情況下，全部增碳劑一次性加入鐵液中，河南石墨增碳劑，同時(shí)用固體爐料將其壓入鐵液中不讓其露出鐵液表面。這種方法鐵液增碳可達(dá)1.0%以上。 2.爐外增碳: (1)包內(nèi)噴石墨粉選用石墨粉做增碳劑，吹入量為40kg/t，預(yù)期能使鐵液含碳量從2%增到3%。隨著鐵液碳含量逐漸升高，碳量利用率下降，增碳前鐵液溫度1600℃，增碳后平均為1299℃。噴石墨粉增碳，一般采用氮?dú)庾鲚d體，但在工業(yè)生產(chǎn)條件下，用壓縮空氣更方便，而且壓縮空氣中的氧燃燒產(chǎn)生CO,化學(xué)反應(yīng)熱可補(bǔ)償部分溫降，而且CO的還原氣氛利于改善增碳效果。 (2)出鐵時(shí)使用增碳劑可將100-300目的石墨粉增碳劑放到包內(nèi)，或從出鐵槽隨流沖入，出完鐵液后充分?jǐn)嚢?，盡可能使碳溶解吸收，碳的回收率在50%左右。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南石墨增碳劑" src="http://tyunfile.71360.com/UpLoadFile/xtzhuyou/2019/7/636984622596282539/6369846225962825391906664.jpg"></div><p style="text-indent:25px">增碳劑的使用已經(jīng)越來越普遍，增碳效果也是大家有目共睹的。下面為大家介紹一下增碳劑使用量的把握的知識(shí)，希望對(duì)您有所幫助。　　在冶煉過程中，由于配料或裝料不當(dāng)以及脫碳過量等原因，有時(shí)造成鋼或鐵中含量沒有達(dá)到預(yù)期的要求，這時(shí)要向鋼或鐵液中增碳。通常用來增碳的物質(zhì)主要有無煙煤粉，增碳生鐵，電極粉，石油焦粉，瀝青粉，木炭粉和焦炭粉。對(duì)增碳劑的要求是，固定碳越高越好，灰份，揮發(fā)份及硫份等有害雜質(zhì)含量越低越好，以免污染鐵水。增碳劑就是要在加入后可以有效提高鐵液中碳的含量，所以增碳劑的固定碳含量一定不能太低，否則要達(dá)到一定的含碳量，就需要加入相比高碳的增碳劑更多的量，這樣無疑增加了增碳劑中其他不利元素的量，使鐵液不能獲得較好的收益。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南石墨增碳劑" src="http://tyunfile.71360.com/UpLoadFile/xtzhuyou/2019/7/636984622900887494/6369846229008874942686659.jpg"></div><p style="text-indent:25px">鑄友牌質(zhì)量增碳劑特性： 1、化學(xué)成分純凈，高碳、低硫、有害成分極微，吸收率高。 2、產(chǎn)品石墨化程度高，提高原鐵液的形核能力,在孕育中增加球墨鑄鐵的墨球數(shù)量，在電爐鐵液中增加石墨晶核，使石墨在鑄件中的分布細(xì)化、均勻。 3、顆粒大小適中，孔隙度大，吸收速度快。 4、性能優(yōu)異、穩(wěn)定。質(zhì)量增碳劑有助于降低冶煉生產(chǎn)成本，提高冶煉金屬及鑄件的質(zhì)量，使用戶獲得成本及質(zhì)量雙方面的效益。邢臺(tái)市鑄友耐火材料有限公司 </p></p><br /><p>文章來源地址:
