Carburizing ihe dị ka mmepụta nke akụrụngwa nwere ike kewaa n'ime: osisi carbon, coal carbon, coke carbon, graphite.
1. Osisi carbon
2. Ụdị carbon carbon
* General calcining coal carburizer: Ọ bụ ngwaahịa nke ala ash na obere sọlfọ ezi na-asacha anthracite na calcination ọkụ mgbe ihe dị ka 1250 ℃ elu okpomọkụ calcination, tumadi emepụtara na Ningxia, Inner Mongolia. Ọdịnaya carbon n'ozuzu bụ 90-93%. A na-ejikarị ya eme ụlọ ọrụ na-emepụta ígwè, na ụfọdụ ụlọ ọrụ nkedo na-eji ígwè nkedo isi awọ. N'ihi nhazi kọmpat nke mkpụrụ ndụ carbon ya, usoro mmịpụta okpomọkụ na-adị ngwa ngwa na oge dị ogologo.
* Asphalt coking carburizer: ngwaahịa sitere na coal tar hydrogenation iji mepụta mmanụ. Ọ bụ carbon dị elu, sọlfọ dị ala na obere nitrogen carburizer ewepụtara na tar. Ọdịnaya carbon dị n'etiti 96-99.5%, ọdịnaya na-agbanwe agbanwe dị ala, ihe owuwu ahụ dị oke, ike igwe na iyi nguzogide nke ahụ dị oke elu, eserese dị mfe.
* Metallurgical coke carburizing gị n'ụlọnga: coking coal firing, na-abụkarị cupola na nnukwu coke, na mgbakwunye na agbaze, ma na-eji metal ụgwọ carburizing.
3. Coke (petroleum coke) carbon
* Carburizer Coke Calcined: Ọ bụ ngwaahịa nke coke petroleum sọlfọ dị ala, nke a na-edozi n'ime ọkụ calcination na ogo 1300-1500 mgbe ọ wepụsịrị mmiri, adịghị ike na adịghị ọcha. Ọdịnaya carbon ya kwụsiri ike na ihe dịka 98.5%, yana sọlfọ ọdịnaya ya na-erughị 0.5% ma ọ bụ 1%. Njupụta ya bụ kọmpat, ọ dịghị mfe ire ere, na oge iji ya bụ ọkara. A na-etinyekarị mmepụta na Shandong, Liaoning, Tianjin. N'ihi ọnụahịa ya na ọkọnọ ya n'ọtụtụ ụdị nke onye na-ahụ maka carburizing nwere uru, a na-ejikarị ahịa ahụ eme ihe.
* Onye na-ahụ maka mmanụ ụgbọ ala coke carburizing: mmanụ ala coke na graphitic agbaze ọkụ mgbe ogo 3000 nke mmepụta okpomọkụ dị elu nke ngwaahịa eserese, yana nnabata ngwa ngwa, carbon dị elu na uru sọlfọ dị ala. Ọdịnaya carbon ya bụ 98-99%, sọlfọ ọdịnaya index bụ ala karịa 0.05% ma ọ bụ 0.03%, na-emepụta ebe na-lekwasị na Inner Mongolia, Jiangsu, Sichuan na na. Ụzọ ọzọ na-abịa site graphite electrode ọnwụ n'efu, n'ihi na graphite electrode onwe ya mgbe graphitization ọgwụgwọ, ihe mkpofu nwekwara ike-eji dị ka a carburizing gị n'ụlọnga maka ígwè igwe nri.
* Semi-graphitic petroleum coke carburizer: graphitic okpomọkụ adịghị elu dị ka graphitic carburizer, carbon ọdịnaya n'ozuzu karịa 99.5, sọlfọ ọdịnaya dị elu karịa graphitic carburizer, n'okpuru 0,3%.
4. Ụdị eserese
* Onye na-arụ ọrụ graphite dị ka ụwa: bụ ngwa nke graphite dị ka ụwa na ígwè na nchara nchara ma ọ bụ nkedo carburizing, ebe bụ isi na-emepụta ya na Hunan, bụ ngwa ngwa nke ntụ ntụ graphite nke ụwa, na-abụkarị ọdịnaya carbon na 75-80. %, enwere ike sachaa ya ka ọ mụbaa ọdịnaya carbon nke ngwaahịa.
* Onye na-ahụ maka graphite eke eke: tumadi iji flake graphite, ọdịnaya carbon na 65-99%, nkwụsi ike dị ala, nke a na-ejikarị na igwe igwe igwe.
* Ngwakọta carburizing mejupụtara: graphite ntụ ntụ, coke ntụ ntụ, petroleum coke na ihe ndị ọzọ ụkwụ, na-agbakwunye dị iche iche binders na igwe nwere ike pịa n'ime udi, n'ihi na mkpanaka granular. Ọdịnaya carbon na-adịkarị n'etiti 93 na 97%, na sọlfọ ọdịnaya adịghị akwụsi ike, n'ozuzu n'etiti 0.09 na 0.7.
