Iko kushandiswa kweakasiyana recarburizers
Carburizer ikemikari zvinhu zvinogona kunyatso vandudza carbonization mhedzisiro yezvinhu uye nharaunda yesimbi.Kune akawanda carburizer anoshandiswa muindasitiri yesimbi nesimbi.Akasiyana recarburizers ezvinangwa zvakasiyana ane akasiyana mhedzisiro.
1. Artificial graphite recarburizer
Iyo huru yakasvibirira yeartificial graphite iupfu calcined petroleum coke, umo pitch (kana pure organic pregelatinization) inowedzerwa sebinder, uye zvishoma zvezvimwe zvinhu zvinobatsira zvinowedzerwa.Nezvinhu zvakasiyana-siyana zvakasvibirira, inotsikirirwa uye inoumbwa, uye inogadziriswa mumhepo isina-oxidizing pa 2500-3000 ° C kuti iite graphitized.Mushure mekupisa kwakanyanya kurapwa, zviri mukati madota, sarufa uye gasi zvakaderedzwa zvakanyanya.
Nekuda kwemutengo wepamusoro wezvigadzirwa zvekugadzira magirafu, mazhinji eanowanzo shandiswa ekugadzira graphite recarburizers anoshandisa zvinhu zvakadzokororwa senge machipisi, tsvina electrodes uye magraphite blocks pakugadzira magraphite electrode munzvimbo dzekuwana kuderedza mutengo wekugadzira.Paunenge uchinyungudutsa ductile iron, kuitira kuti iyo metallurgical yemhando yesimbi yakakandwa iwedzere, iyo recarburizer inofanirwa kunge iri yekugadzira graphite.
Kushandiswa kwegraphite recarburizer: Graphite recarburizer inogona kuvandudza iyo metallographic chimiro chekukandira, nekukurumidza kugadzira graphite musimboti musimbi yakakandwa, kupfupisa iyo carbonization nguva, uye kugadzirisa iyo carbonization maitiro.
2. Petroleum coke recarburizer
Petroleum coke irecarburizer inoshandiswa zvakanyanya, uye petroleum coke ndeye-chigadzirwa chekunatsa mafuta asina kuchena.Oiri yakasara uye petroleum pitch inowanikwa nekumanikidzwa kana vacuum distillation inogona kushandiswa seyakagadziriswa kugadzirwa kwepetroleum coke, uye petroleum coke inogona kuwanikwa mushure mekubika.Kubuda kwepetroleum coke yakasvibirira ishoma pane huwandu hwemafuta asina kuchena, uye kusachena kwemafuta epetroleum coke kwakakwira, saka haigone kushandiswa zvakananga se carburizer uye inofanira kutanga yaverengerwa.Green petroleum coke ine spongy, tsono, granular uye fluid maumbirwo.
Kushandiswa kwepetroleum coke recarburizer: Petroleum coke recarburizer inogona kunyatso kuwedzera tembiricha yechoto, haingogone chete kuwedzera tembiricha yechoto, asi zvakare kugadzirisa goho resimbi, kuvandudza nekuvandudza hutsinye hwesimbi.
3. Coke uye Anthracite
Mune yemagetsi arc furnace steelmaking process, coke kana anthracite inogona kuwedzerwa se recarburizer.Induction furnace inonyungudutsa simbi yakakandwa haiwanzo kushandiswa serecarburizer nekuda kwedota rayo rakawanda uye kuparara kwemukati.Iyo calciner inoverengerwa ne anthracite, uye tembiricha yecalcination ndeye 1200-1300.Black granular, simbi inopenya, yakagadziriswa kabhoni 85-93, ine mwero sarufa uye nitrogen yemukati.
Kushandisa calcined marasha recarburizer: Chinangwa che calcined marasha recarburizer ndechekuwedzera kabhoni uye kupfupisa iyo carbonization nguva.Iko kushandiswa kwe calcined marasha recarburizer kunogona kunyatso kuchengetedza nguva.
