Carburizing agent, e faʻaaogaina i le uamea ma le tuʻuina atu o alamanuia, mo le faʻapalapala, desulfurization ma isi mea fesoasoani. O le faʻaaogaina lautele i le uʻamea ma le uʻamea uʻamea uʻamea o le faʻaogaina lea o le carbon content mu i le faagasologa o le uʻamea ma le uamea faʻafefe ma le faʻaopoopoga o mea o loʻo i ai carbon.
I le faʻafefeteina o le uʻamea ma oloa uʻamea, e masani lava ona o le taimi faʻafefeteina, taimi taofi, taimi faʻafefeteina ma isi mea, o le faʻafefeteina o elemene kaponi i totonu o le uʻamea vai e faʻateleina, e mafua ai le faʻaitiitia o le carbon content o le uʻamea vai, e mafua ai. e le mafai ona ausia e le carbon anotusi o le u'amea vai le taua theoretical faamoemoeina o le faamamaina. O le mea lea, e manaʻomia le faʻaopoopoina o oloa faʻapipiʻi e faʻafetaui ai le carbon content of steel, lea o se faʻaopoopoga fesoasoani taua mo le gaosiga o le sila maualuga.
Carburizing sui e tusa ai ma le gaosiga o mea mata e mafai ona vaevaeina i: laupapa carbon, koale carbon, coke carbon, graphite.
1. Wood carbon
2. Kaponi ituaiga koale
* General calcining carburizer koale: O se oloa o le maualalo lefulefu ma le maualalo sulfur fufulu lelei anthracite i calcination ogaumu pe a ma le 1250 ℃ maualuga vevela calcination, e masani ona gaosia i Ningxia, Inner Mongolia. Ole mea masani ole carbon e 90-93%. E masani ona faʻaaogaina i pisinisi e faia ai le uamea, ma o nisi o faʻasalalauga e faʻaaogaina i le uʻamea efuefu. Ona o le faʻapipiʻi faʻapipiʻi o ona mole mole kaponi, o le faʻaogaina o le vevela e telegese ma umi le taimi.
* Mea fa'amea fa'a'ala'au fa'a'asala: ose mea e maua mai i le fa'asa'oina o le ta koale e maua ai le suau'u. O le kaponi maualuga, maualalo le sulfur ma le maualalo o le nitrogen carburizer e maua mai le ta. O le carbon anotusi o loʻo i le va o le 96-99.5%, o le mea e faʻafefeteina e maualalo, o le fausaga e mafiafia, o le malosi faʻainisinia ma le faʻaogaina o le faʻaogaina o vaega e maualuga tele, faigofie graphitization.
* Metallurgical coke carburizing agent: coking coal firing, e masani lava cupola ma coke lapopoa, e faaopoopo atu i le smelting, ae faaaoga foi mo uʻamea tau carburizing.
3. Coke (petroleum coke) carbon
* Calcined coke carburizer: O se oloa e faia i le suauʻu suauʻu sulfur coke e pei o mea mata, lea e gaosia i totonu o se ogaumu calcination i le 1300-1500 tikeri pe a uma ona aveese le susu, volatiles ma mea leaga. O lona anotusi fa'amautu kaponi e masani ona mautu pe a ma le 98.5%, ma o lona sulfur anotusi e tele lava ina itiiti ifo i le 0.5% po'o le 1%. O lona mafiafia e laititi, e le faigofie ona pala, ma o lona taimi fa'aoga e feololo. O gaosiga o lo'o fa'atumauina i Shandong, Liaoning, Tianjin. Ona o lona tau ma sapalai i le tele o vaega o le carburizing agent e iai se avanoa, o le maketi e sili atu ona faʻaaogaina.
* Graphitic suauu coke carburizing sui: suauu coke i graphitic smelting ogaumu ina ua mavae 3000 tikeri o le vevela maualuga gaosiga o oloa graphitic, ma absorption vave, maualuga carbon ma le sulfur tulaga lelei. O lona anotusi carbon o le 98-99%, o le sulfur content index e maualalo ifo nai lo le 0.05% poʻo le 0.03%, o le gaosiga o vaega o loʻo faʻatumauina i totonu Mongolia, Jiangsu, Sichuan ma isi. O le isi auala e sau mai le graphite electrode tipi otaota, ona o le graphite electrode lava ia ina ua uma togafitiga graphitization, e mafai foi ona faaaoga otaota e avea o se sui carburizing mo uʻamea uʻamea.
* Semi-graphitic petroleum coke carburizer: graphitic vevela e le maualuga e pei o graphitic carburizer, carbon anotusi e masani lava sili atu nai lo 99.5, sulfur anotusi e maualuga atu nai lo graphitic carburizer, i lalo ole 0.3%.
4. Ituaiga graphite
* Eleele-pei graphite carburizing sui: o le faaaogaina o le eleele-pei graphite i uʻamea ma uʻamea smelting po o le lafo carburizing, lona nofoaga autu gaosia i Hunan, o le faaaogaina tuusao o le eleele-pei o le pauta graphite, e masani lava carbon i totonu 75-80 %, e mafai ona faʻamamāina e faʻateleina ai le oloa carbon content.
* Fa'alenatura graphite carburizing sui: e masani lava i flake graphite, carbon i totonu o le 65-99%, maualalo mautu, e masani ona faʻaaogaina i fale uʻamea.
* Su'esu'ega fa'apipi'i: graphite powder, coke powder, petroleum coke ma isi mea vae, fa'aopoopo mea fa'apipi'i eseese ma le masini e mafai ona oomi i foliga, mo le to'oto'o granular. O le kaponi o lo'o i totonu e masani lava i le va o le 93 ma le 97%, ma o le sulfur i totonu e matua le mautu, masani i le va o le 0.09 ma le 0.7.
