Ana amfani da sinadarin carbonizing a masana'antar ƙarfe da siminti, don yin carburizing, desulfurization da sauran kayan taimako. Mafi amfani da shi a masana'antar narke ƙarfe da ƙarfe shine don rama yawan sinadarin carbon da aka ƙone yayin narkewar ƙarfe da ƙarfe da kuma ƙara abubuwan da ke ɗauke da carbon.
A tsarin narkewar kayayyakin ƙarfe da na ƙarfe, sau da yawa saboda lokacin narkewa, lokacin riƙewa, lokacin zafi da sauran abubuwa, asarar narkewar abubuwan carbon a cikin baƙin ƙarfe yana ƙaruwa, wanda ke haifar da raguwar yawan carbon a cikin baƙin ƙarfe, wanda ke haifar da yawan carbon a cikin baƙin ƙarfe mai ruwa ba zai iya kaiwa ga ƙimar da ake tsammani na tacewa ba. Saboda haka, ya zama dole a ƙara samfuran carbizing don daidaita yawan carbon a cikin ƙarfe, wanda shine ƙarin ƙarin taimako don samar da ƙarfe mai inganci.
Ana iya raba wakilin carburetion bisa ga samar da albarkatun ƙasa zuwa: carbon na itace, carbon na kwal, coke carbon, graphite.
1. Carbon na itace
2. Carbon irin kwal
* Kaburizer na kwal na calcining gabaɗaya: Samfurin anthracite ne mai ƙarancin toka da ƙarancin sulfur mai laushi a cikin tanderun calcination bayan kimanin 1250℃ mai zafi, galibi ana samarwa a Ningxia, Inner Mongolia. Jimlar sinadarin carbon shine kashi 90-93%. Ana amfani da shi galibi a cikin masana'antun yin ƙarfe, kuma wasu kamfanonin siminti ana amfani da su a cikin ƙarfe mai launin toka. Saboda ƙaramin tsarin ƙwayoyin carbon ɗinsa, tsarin shaƙar zafi yana da jinkiri kuma lokaci yana da tsawo.
* Carburizer na kwalta: wani sinadari ne da ake samu daga kwalta hydrogenation don samar da mai. Yana da sinadarin carbon mai yawa, ƙarancin sulfur da ƙarancin nitrogen carburizer da aka fitar daga kwalta. Yawan sinadarin carbon yana tsakanin kashi 96-99.5%, yawan sinadarin da ke canzawa yana da ƙasa, tsarin yana da yawa, ƙarfin injina da juriyar lalacewa na ƙwayoyin suna da yawa, kuma suna da sauƙin graphitization.
* Maganin karafa na coke: ana amfani da shi wajen harba kwal, yawanci ana yinsa ne da babban coke, ban da narkewa, amma kuma ana amfani da shi wajen yin carburizing na ƙarfe.
3. Coke (petroleum coke) carbon
* Kaburizer na Coke da aka yi da Calcined: Samfuri ne da aka yi da man fetur mai ƙarancin sulfur a matsayin kayan da aka sarrafa, wanda ake sarrafawa a cikin tanderun calcination a digiri 1300-1500 bayan cire danshi, abubuwan da ke canzawa da ƙazanta. Yawan sinadarin carbon da ke cikinsa gabaɗaya yana da ƙarfi a kusan kashi 98.5%, kuma yawan sinadarin sulfur ɗinsa galibi ƙasa da kashi 0.5% ko 1%. Yawansa yana da ƙanƙanta, ba shi da sauƙin ruɓewa, kuma lokacin amfani da shi matsakaici ne. Ana samunsa galibi a Shandong, Liaoning, Tianjin. Saboda farashinsa da wadatarsa a cikin nau'ikan sinadarai da yawa na carburizing yana da fa'ida, ana amfani da kasuwa sosai.
* Maganin carburizing na coke na man fetur mai siffar graphitic: coke na man fetur a cikin tanda mai narkewa bayan samar da samfuran graphitic mai zafi mai digiri 3000, tare da shan ruwa da sauri, fa'idodin carbon mai yawa da ƙarancin sulfur. Yawan sinadarin carbon ɗinsa shine kashi 98-99%, ma'aunin sinadarin sulfur ƙasa da kashi 0.05% ko 0.03%, yankunan da ake samarwa suna da yawa a cikin Inner Mongolia, Jiangsu, Sichuan da sauransu. Wata hanya kuma ta fito ne daga sharar yanke wutar lantarki ta graphite, saboda electrode na graphite da kansa bayan maganin graphitization, ana iya amfani da sharar a matsayin wakilin carburizing ga masana'antar ƙarfe.
* Carburizer na man fetur na Semi-graphitic: zafin graphitic bai kai na graphitic carburizer ba, yawan sinadarin carbon gabaɗaya ya fi 99.5, yawan sinadarin sulfur ya fi na graphitic carburizer girma, ƙasa da 0.3%.
4. Nau'in Graphite
* Wakili mai kama da duniya mai siffar graphite: shine amfani da graphite mai kama da ƙasa a cikin narkewar ƙarfe da ƙarfe ko simintin simintin siminti, babban yankin da ake samarwa a Hunan, shine amfani da foda mai kama da ƙasa kai tsaye, yawanci yawan sinadarin carbon a cikin kashi 75-80%, ana iya tsarkake shi don ƙara yawan sinadarin carbon.
* Maganin carburizing na graphite na halitta: galibi yana rage girman graphite, yawan sinadarin carbon a cikin kashi 65-99%, ƙarancin kwanciyar hankali, galibi ana amfani da shi a masana'antar ƙarfe.
* Maganin carburizing mai haɗawa: foda graphite, foda coke, coke na man fetur da sauran kayan ƙafa, ƙara nau'ikan mahaɗa daban-daban tare da injin za a iya matse su zuwa siffar, don granular sandar. Yawan sinadarin carbon gabaɗaya yana tsakanin kashi 93 zuwa 97%, kuma yawan sinadarin sulfur ba shi da ƙarfi sosai, gabaɗaya tsakanin 0.09 da 0.7.
