Recarburizer kugadzira maitiro uye zvigadzirwa
A recarburizer chinhu chine kabhoni.Carburizers inowedzerwa panguva yekunyungudutsa kuti iwedzere kabhoni yakarasika panguva yekunyungudutswa kwesimbi.Isu tinoziva kuti kune akawanda marudzi ezvekudzoreredza, senge petroleum coke recarburizers, artificial graphite recarburizers, nezvimwe, saka izvo mbishi zvinhu zvinodiwa kune recarburizers zvakare zvakasiyana, saka ndezvipi zvimisikidzo zvezvigadziriso?Iyo process ye recarburizers ndeye Chii?Xiaobian ichakuudza nezve zvigadzirwa uye maitiro anodiwa kune recarburizer.
Raw zvinhu zvinodiwa recarburizers
Kune akawanda marudzi emhando yezvigadzirwa zvemarecarburizer, anosanganisira marasha, marasha-akavakirwa kabhoni, coke, graphite, mbishi petroleum coke, nezvimwe, izvo kune akawanda madiki mapoka uye akasiyana siyana.
Parizvino, mazhinji evanodzoreredza pamusika, anosanganisira graphite electrodes, graphitized petroleum coke, nezvimwewo, shandisa mbishi petroleum coke.Crude petroleum coke inowanikwa nekukokwa kwemafuta akasara uye petroleum pitch inowanikwa nekunyungudutswa kwemafuta asina kuchena pasi pemhepo yemhepo kana vacuum.Raw petroleum coke ine hutsvina hwepamusoro uye haigone kushandiswa zvakananga seyakagadziriswazve.Inofanirwa kuve yakaverengerwa kana graphitized.Yepamusoro-mhando recarburizers kazhinji inoda graphitization.Pasi pemamiriro ekushisa kwepamusoro, kurongeka kwekabhoni maatomu ari mu microscopic chimiro che graphite, saka inonzi graphitization.Graphitization inogona kuderedza zvirimo zvetsvina mune recarburizer, kuwedzera kabhoni yemukati meiyo recarburizer, uye kuderedza iyo sulfur yemukati.Recarburizers inoshandiswa kukanda, iyo inogona kuwedzera zvakanyanya kuwanda kwesimbi, kuderedza huwandu hwenguruve iron kana kuchengetedza simbi yenguruve.
Carburizer Process
Nekuda kweakasiyana-siyana ezvigadzirwa zvemarecarburizers, maitiro acho akasiyana, asi pane kunyanya anotevera matatu:
1. Calcination
Carbonaceous raw materials yakaverengerwa patembiricha yepamusoro ye1200-1500 °C pasina mweya.Calcination inokonzeresa shanduko muchimiro uye physicochemical zvimiro zveakasiyana mbishi zvinhu.Ndiyo nzira yekupisa yekupisa ye recarburizer.Ose anthracite nepetroleum coke ane humwe huwandu hwezvinhu zvinoshanduka uye zvinoda calcination.Zvisinei, kana petroleum coke nepitch coke zvasanganiswa uye zvoshandiswa kusati kwabikwa, zvinofanira kutumirwa kumucheni wemoto kunoongororwa pamwe chete nepetroleum coke.
2. Kugocha
Kugocha inzira yekurapa kupisa umo iyo yakatsikirirwa chikafu chakasvibirira chinopisa pane imwe yekupisa mwero mumudziyo wekudzivirira muchoto chekupisa pasi pemamiriro ekuparadzanisa mweya.
Chinangwa chekugocha ndechekubvisa kuputika.Kazhinji, dzinenge gumi marudzi ezvinoputika anoburitswa mushure mekugochwa.Naizvozvo, goho rekugochwa rinowanzoita makumi mapfumbamwe;iyo binder yakabikwa, uye chigadzirwa chinogochwa maererano nemamwe maitiro ekugadzirisa, kuitira kuti binder ivhare, uye coke network inoumbwa pakati pezvinhu zvakasvibirira, izvo zvinonyatsobatanidza zvinhu zvose zvakasvibiswa nehukuru hwakasiyana-siyana pamwe chete.Ita # # zvigadzirwa zvive nezvimwe zvemuviri uye zvemakemikari zvimiro.Pasi pemamiriro akafanana, iyo yakakwirira yekubika kubika, zviri nani kunaka;munyaya ye geometry yakagadziriswa, chigadzirwa chichanyorova uye binder ichatama panguva yekubika.Sezvo kutonhora kunowedzera, coking network inoumbwa, iyo inoomesa chigadzirwa.Nokudaro, chimiro chayo hachichinje sezvo kutonhora kunowedzera.
3. Extrusion
Chinangwa che extrusion process ndechekuita kuti iyo yakasvibira ipfuure nemuforoma yeimwe chimiro pasi pekumanikidzwa, uye kuva billet ine imwe chimiro uye saizi mushure mekuumbwa uye kukanganiswa kwepurasitiki.Iyo extrusion molding process inonyanya kuve yepurasitiki deformation maitiro epaste.Iyo extrusion process inoitika mukamuri yemidziyo uye nemuromo wakakombama.Zvinhu zvinopisa zviri mukamuri zvinosundirwa nepirunger huru kumashure.Kumanikidzwa kuenderera mberi kubviswa kwegasi kubva kune yakasvibirira, kuenderera kusungirirwa kweiyo mbishi, uye panguva imwe chete kufamba kweiyo mbishi kuenda mberi.Kana iyo mbishi inofamba mu cylindrical chikamu chekamuri yemidziyo, iyo mbishi inogona kutorwa seyekuyerera yakagadzikana, uye yega yega chidimbu layer inofamba ichienderana.Kana iyo yakasvibirira ichipinda mumuromo weextrusion uye iine arc-yakaita deformation, iyo mbishi padyo nemadziro emadziro inosangana nekupokana kwakanyanya painofambira mberi, uye iyo layer yechinhu inotanga kukotama.Iyo yakasvibira ine akasiyana ekufambira mberi kumhanya, uye yemukati mbishi zvinhu inofambira mberi.Naizvozvo, kuwanda kwechigadzirwa pamwe neiyo radial gwara haina yunifomu, nekudaro ichiunza kushushikana kwemukati kunokonzerwa nekuyerera kwakasiyana kwemazinga emukati uye ekunze akaturikidzana mune yakawedzera block.Mushure mekunge paste inopinda mukati yakatwasuka deformation chikamu, inowedzerwa uye inoumbwa.
Iyo extrusion nzira inoda kuwedzera yakawandisa binder yekuumba, uye iyo kabhoni yemukati kazhinji haizadzise zvinodiwa zvemhando yepamusoro recarburizers.Yakadzvanywa graphite poda, nekuti ibhuroka yakasimba, haina porous chimiro, saka iyo yekunyudza kumhanya uye kunyudza mwero haina kunaka seyakaverengerwa uye calcined recarburizers.
