Mukuita kunyungudutsa, nekuda kwekusina kufanira dosing kana kubhadharisa uye yakawandisa decarbonization uye zvimwe zvikonzero, dzimwe nguva kabhoni yemukati musimbi kana simbi haizadzise zvinotarisirwa zvinodiwa, saka zvinodikanwa carburize simbi kana mvura simbi.Zvinhu zvikuru zvinowanzoshandiswa kugadzira carburizing ianthracite powder, carburized pig iron, electrode powder, petroleum coke powder, asphalt coke, charcoal powder uye coke powder.Zvinodiwa zve carburizer ndezvokuti iyo yakakwirira yakagadziriswa kabhoni, zviri nani, uye yakadzika iyo inokuvadza tsvina yakadai sedota, zvinhu zvinoputika uye sulfuri, zviri nani, kuitira kuti usasvibisa simbi.
Iko kunyungudutswa kwekukandira kunoshandisa yemhando yepamusoro recarburizer mushure mekupisa kwakanyanya kwepetroleum coke ine tsvina shoma, inova ndiyo inonyanya kukosha chinongedzo mukuita carburizing.Hunhu hweiyo recarburizer hunosarudza mhando yesimbi yemvura, uye zvakare inotarisisa kana iyo graphitization mhedzisiro inogona kuwanikwa.Muchidimbu, kudzikisa iron shrinkage recarburizer inoita basa rakakosha.
Kana simbi yese yakanyungudutswa muchoto chemagetsi, iyo recarburizer yakange yavezwa inofarirwa, uye recarburizer iyo yakave negraphitized pakupisa kwepamusoro inogona kushandura maatomu ekabhoni kubva pakurongeka kwekutanga kurongeka kuita pepa, uye sheet graphite inogona kuve yakanyanya kunaka. musimboti wegraphite nucleation kukurudzira graphitization.Naizvozvo, isu tinofanirwa kusarudza recarburizer iyo yakabatwa nepamusoro tembiricha graphitization.Nekuda kweiyo yakanyanya tembiricha graphitization kurapwa, iyo sulfur yemukati inogadzirwa SO2 gasi kupukunyuka uye kuderedza.Naizvozvo, iyo sulfur yemukati yemhando yepamusoro recarburizer yakadzikira, kazhinji isingasviki 0.05%, uye zvirinani zvakatoderera kupfuura 0.03%.Panguva imwecheteyo, iyi zvakare chiratidzo chisina kunanga chekuti yakabatwa nepamusoro tembiricha graphitization uye kana graphitization yakanaka.Kana iyo yakasarudzwa recarburizer isina graphitized pakupisa kwakanyanya, iyo nucleation kugona kwegraphite inoderedzwa zvakanyanya, uye kugona kwegraphitization kwakadzikira, kunyangwe iyo yakaenzana kabhoni inogona kuwanikwa, asi mhedzisiro yakasiyana zvachose.
Iyo inonzi recarburizer ndeyekunyatso wedzera kabhoni yemukati mune yemvura iron mushure mekuwedzera, saka iyo yakagadziriswa kabhoni yemukati yerecarburizer haifanirwe kunge yakadzikira, zvikasadaro kuti uwane imwe kabhoni yemukati, unofanirwa kuwedzera zvimwe zvigadzirwa kupfuura zvakakwirira. -carbon recarburizer, iyo pasina mubvunzo inowedzera huwandu hwezvimwe zvisingafadzi zvinhu mu carburizer, kuitira kuti simbi yemvura isawane kudzoka kuri nani.
Yakaderera sarufa, nitrogen uye hydrogen zvinhu ndiyo kiyi yekudzivirira kugadzirwa kwenitrogen pores mukukanda, saka iyo nitrogen yemukati yerecarburizer inofanirwa kuve yakaderera sezvinobvira.
Zvimwe zvinongedzo zveiyo recarburizer, senge huwandu hwehunyoro, dota, kuvhuvhuta, iyo yakaderera iyo yakagadziriswa kabhoni, iyo yakakwira huwandu hweyakagadzika kabhoni, saka iyo yakawanda yakagadziriswa kabhoni, zviri mukati meizvi zvinokuvadza hazvifanirwe kuve. high.
Kune dzakasiyana nzira dzekunyungudika, mhando dzechoto uye saizi yechoto chinonyunguduka, zvakakoshawo kusarudza iyo chaiyo recarburizer particle size, iyo inogona kunyatso kuvandudza chiyero chekunyudza uye kunyudzwa kweiyo recarburizer musimbi yemvura, uye kudzivirira iyo oxidation uye. kupisa kurasikirwa kwe carburizer kunokonzerwa nediki diki saizi.Saizi yaro yepakati ndiyo yakanyanya kunaka: 100kg choto ishoma pane 10mm, 500kg choto iri pasi pe15mm, 1.5 tani choto iri pasi pe20mm, 20 tani choto iri pasi pe30mm.Mukushandura kunyungudutsa, kana yakakwira kabhoni simbi inoshandiswa, recarburizer ine tsvina shoma inoshandiswa.Izvo zvinodikanwa zveiyo recarburizer inoshandiswa mune yepamusoro inoputika inoshandura simbi yakakwira yakagadziriswa kabhoni, yakaderera yemukati yemadota, inoputika uye sarufa, phosphorus, nitrogen uye kumwe kusvibiswa, uye yakaoma, yakachena, ine mwero particle size.Yayo yakagadziriswa kabhoni C≥96%, inoshanduka-shanduka ≤1.0%, S≤0.5%, mwando ≤0.5%, particle size mu 1-5mm.Kana saizi yechikamu ichi yakanyanya kunaka, iri nyore kupisa, uye kana yakanyanya kukwasha, inoyangarara pamusoro pemvura yesimbi uye haisi nyore kunyudzwa nesimbi yakanyungudutswa.Kune induction yevira particle size mu 0.2-6mm, iyo simbi uye imwe dema simbi particle size mu 1.4-9.5mm, high carbon steel inoda yakaderera nitrogen, particle size mu 0.5-5mm zvichingodaro.Iyo chaiyo inodiwa zvinoenderana nechoto chechoto mhando yekunyungudutsa workpiece mhando uye mamwe mashoko chaiwo kutonga uye kusarudzwa.
