Carburizing agent, inoshandiswa muindasitiri yesimbi uye yekukandira, yecarburizing, desulfurization uye zvimwe zvinhu zvinobatsira. Iyo inonyanya kushandiswa muindasitiri yekunyungudutsa simbi uye simbi ndeyekugadzira iyo kabhoni yemukati yakapiswa mukuita kwesimbi nesimbi kunyunguduka uye kuwedzera kwekabhoni-ine zvinhu.
Mukunyungudutsa kwesimbi nesimbi zvigadzirwa, kazhinji nekuda kwekunyunguduka kwenguva, kubata nguva, nguva yekupisa uye zvimwe zvinhu, kunyunguduka kwekabhoni zvinhu muiron yemvura kunowedzera, zvichikonzera kudzikira kwekabhoni yemvura yesimbi, zvichikonzera iyo kabhoni yemukati yesimbi yemvura haigone kusvika kune inotarisirwa kukosha kwekunatsa. Naizvozvo, zvinodikanwa kuwedzera zvigadzirwa zvecarburizing kugadzirisa kabhoni yesimbi, inova yakakosha yekuwedzera yekuwedzera mukugadzirwa kwesimbi yemhando yepamusoro.
Carburizing agent zvinoenderana nekugadzirwa kwezvinhu zvakabikwa zvinogona kukamurwa kuita: huni kabhoni, marasha kabhoni, coke kabhoni, graphite.
1. Wood carbon
2. Coal type carbon
* General calcining marasha carburizer: Icho chigadzirwa cheyakaderera dota uye yakaderera sarufa yakanaka yekuwachisa anthracite muchoto checalcination mushure menge 1250 ℃ yakanyanya tembiricha calcination, inonyanya kugadzirwa muNingxia, Inner Mongolia. Iyo yakawanda kabhoni yemukati ndeye 90-93%. Inonyanya kushandiswa mumabhizinesi ekugadzira simbi, uye mamwe mabhizinesi ekukanda anoshandiswa mune grey cast iron. Nekuda kweiyo compact dhizaini yayo kabhoni mamorekuru, kupisa kunyura maitiro kunononoka uye nguva yakareba.
* Asphalt coking carburizer: chigadzirwa chemarasha tar hydrogenation kugadzira mafuta. Iyo yakakwira kabhoni, yakaderera sarufa uye yakaderera nitrogen carburizer yakabviswa mutara. Iyo kabhoni yemukati iri pakati pe96-99.5%, iyo inovhuvhuta yemukati yakadzikira, chimiro chakaonda, simba remakanika uye kupfeka kuramba kwezvimedu zvakakwirira, zviri nyore graphitization.
* Metallurgical coke carburizing agent: coking marasha kupfuta, kazhinji kacho ine coke hombe, mukuwedzera pakunyungudutsa, asi zvakare inoshandiswa simbi yekuchaja carburizing.
3. Coke (petroleum coke) carbon
* Calcined coke carburizer: Icho chigadzirwa chakagadzirwa nechepasi-sarufa petroleum coke seyakabikwa, iyo inogadziriswa muchoto checalcination pa1300-1500 madhigirii mushure mekubvisa hunyoro, kuvhuvhuta uye kusvibiswa. Yayo yakagadziriswa kabhoni yemukati kazhinji yakagadzikana pane inosvika 98.5%, uye yayo sarufa yakawanda isingasviki 0.5% kana 1%. Density yaro compact, haisi nyore kuora, uye nguva yekushandisa kwayo iri pakati. Kugadzirwa kunonyanya kuiswa muShandong, Liaoning, Tianjin. Nekuda kwemutengo wayo uye kupa muzvikamu zvakawanda zve carburizing agent ine mukana, musika unonyanya kushandiswa.
* Graphitic petroleum coke carburizing agent: petroleum coke muchoto chekunyungudutsa graphitic mushure me3000 madhigirii ekushisa kwakanyanya kugadzirwa kwezvigadzirwa zvegraphitic, nekukurumidza kunyura, yakakwira kabhoni uye yakaderera sarufa zvakanakira. Iyo kabhoni yemukati ndeye 98-99%, sulfur yemukati index yakaderera pane 0.05% kana 0.03%, nzvimbo dzekugadzira dzakaiswa muInner Mongolia, Jiangsu, Sichuan zvichingodaro. Imwe nzira inobva kune graphite electrode yekucheka tsvina, nokuti graphite electrode pachayo pashure graphitization kurapwa, tsvina inogonawo kushandiswa secarburizing agent yesimbi zvigayo.
* Semi-graphitic petroleum coke carburizer: graphitic tembiricha haina kukwira senge graphitic carburizer, kabhoni yemukati kazhinji yakakura kupfuura 99.5, sulfur yemukati yakakwira kupfuura graphitic carburizer, pazasi 0.3%.
4. Graphite mhando
* Earth-senge graphite carburizing agent: iko kushandiswa kwepasi-senge graphite musimbi nesimbi kunyunguduka kana kukanda carburizing, nzvimbo yayo huru yekugadzira muHunan, iko kushandiswa kwakananga kwepasi-senge graphite poda, kazhinji kabhoni yemukati mu75-80. %, inogona kucheneswa kuwedzera chigadzirwa kabhoni.
* Natural graphite carburizing agent: kunyanya kuflake graphite, kabhoni yemukati mu65-99%, kudzikama kwakadzika, kunowanzo shandiswa mumagetsi esimbi.
* Composite carburizing agent: graphite poda, coke poda, petroleum coke uye zvimwe zvinhu zvetsoka, kuwedzera akasiyana mabhaidhi nemuchina anogona kudzvanywa kuita chimiro, kune tsvimbo granular. Iyo kabhoni yemukati kazhinji iri pakati pe93 ne97%, uye iyo sarufa yemukati haina kugadzikana zvakanyanya, kazhinji pakati pe0.09 ne0.7.
