Nzira yekuisa vira
Mushonga wekabhoni wakakodzera kunyungudutsa muchoto che induction, asi mashandisirwo chaiwo haana kufanana zvichienderana nezvinodiwa pakuita.
(1) Muchitofu chinonyunguduka chepakati nepakati uchishandisa carburizing agent, zvichienderana nechiyero kana zvinodiwa zvakaenzana nekabhoni nezvinhu zvakawedzerwa kuchikamu chezasi chechoto, mwero wekudzoreredza unogona kusvika kupfuura 95%;
(2) kunyunguduka kwesimbi yemvura kana huwandu hwekabhoni husina kukwana kugadzirisa nguva yekabhoni, tanga watamba slag yechoto, wobva wawedzera carburizing agent, kuburikidza nekupisa kwesimbi yemvura, electromagnetic stirging kana artificial stirging kuti inyungudise carbon absorption, chiyero chekupora chinogona kunge chiri madhigirii 90, kana maitiro ecarburizing ekupisa kwepasi, kureva kuti, chaji inonyungudutsa chikamu chetembiricha yesimbi yakanyungudutswa yakaderera, carburizing agent yese kana yawedzerwa kusimbi yemvura, Panguva imwe chete, inodzvanywa musimbi yemvura ine chaji yakasimba kuti irege kubva pamusoro pesimbi yemvura. Nzira iyi inogona kuwedzera carburizing yesimbi yemvura neinopfuura 1.0%.
Kushandisa zvakanaka carburizing agent mu induction oven
1, kushandiswa kwechoto chemagetsi che5T kana kupfuura, zvinhu zvakagadziriswa hazvina kuomarara, tinokurudzira nzira yekuwedzera zvinhu zvakasiyana-siyana. Zvichienderana nezvinodiwa zvekabhoni, zvichienderana nehuwandu hwezvinhu zvinoshandiswa, carburizing agent uye simbi chaji nebhechi rega rega rezvinhu kuti zvibatanidzwe muchoto muchikamu chezasi, jira resimbi chaji imwe jira recarburizing agent, mwero wekunyungudutsa kabhoni unogona kusvika 90%-95%, carburizing agent mu kunyunguduka haitsvedze, kana zvisina kudaro zviri nyore kuputirwa mutsvedza, zvichikanganisa kunyunguduka kwekabhoni;
2. Chitofu chepakati nepakati che induction chinosvika 3T chinoshandiswa, uye zvinhu zvakagadziriswa hazvina kusimba uye zvakagadzikana. Tinokurudzira nzira yekuwedzera zvinhu pakati. Kana simbi yakanyungudutswa ikanyanya kunyungudutswa kana kusiyiwa muchoto, chinhu chinonyungudutswa chinowedzerwa pamusoro pesimbi yakanyungudutswa kamwe chete, uye simbi inowedzerwa ipapo ipapo. Chinhu chinonyungudutswa chinodzvanywa musimbi yakanyungudutswa, kuitira kuti chinhu chinonyungudutswa chive chakabatana nesimbi yakanyungudutswa, uye mwero wekunyungudutswa kwechinhu unopfuura 90%;
3, kushandiswa kwechoto chemagetsi chidiki chepakati nepakati, zvinhu zvakagadzirwa nesimbi yenguruve nezvimwe zvinhu zvine kabhoni yakawanda, tinokurudzira kugadzirisa zvakanaka kabhoni. Mushure mekunyunguduka kwesimbi/simbi yakanyungudutswa, gadzirisa huwandu hwekabhoni, inogona kuwedzerwa pamusoro pesimbi/simbi yakanyungudutswa, kuburikidza nekukurunga kwesimbi (simbi) nemvura kana kukurunga kwekugadzira kuti inyunguduke uye inyere chigadzirwa, mwero wekunyunguduka kwekabhoni ungangoita 93%.
Nzira yekuisa carbon dioxide muchoto chekunze
1. Pfapfaidza upfu hwegirafiti mukati mebhegi
Upfu hweGraphite semushonga wecarburizing, unopfuta huwandu hwe40kg/t, hunogona kutarisirwa kuita kuti huwandu hwekabhoni musimbi yemvura hubve pa2% kusvika pa3%. Sezvo huwandu hwekabhoni musimbi yemvura huchiwedzera zvishoma nezvishoma, mwero wekushandiswa kwekabhoni wakaderera. Tembiricha yesimbi yemvura isati yaiswa carburizing yaive 1600℃, uye avhareji yekupisa mushure mecarburizing yaive 1299℃. Carburizing yeGraphite powder, inowanzo shandiswa nitrogen semutakuri, asi mumamiriro ekugadzirwa kwemaindasitiri, mhepo yakamanikidzwa iri nyore, uye okisijeni iri mumhepo yakamanikidzwa inobvira kugadzira CO2, kupisa kwemakemikari kunogona kutsiva kudonha kwetembiricha, uye mhepo yekuderedza CO2 inobatsira kuvandudza mhedzisiro yecarburizing.
2, kushandiswa kwesimbi inogadzirisa kabhoni
Mushonga we graphite upfu hwe 100-300 carburizing unogona kuiswa mupakeji, kana kubva mudura resimbi rinobuda nekupinda, mushure mekunge simbi yabuda mumvura yanyatsokukurwa, kusvika pazvinogoneka kunyungudutsa kabhoni, mwero wekupora kabhoni ungasvika 50%.
Mukushandisa carburizing agent, unofanira kunyatsoteerera dambudziko iri
Kana nguva yekuwedzera yemushonga wekaburitsi yakanonoka, zviri nyore kuibatanidza pedyo nepasi pechoto, uye mushonga wekaburitsi wakasungirirwa pamadziro echoto hausi nyore kuubatanidza nesimbi yemvura. Kusiyana neizvi, kuwedzera nguva yakanonoka, kucharasikirwa nemukana wekuwedzera kabhoni, zvichikonzera kunyunguduka, nguva yekupisa inononoka. Izvi hazvingononotsi nguva yekuongorora nekugadzirisa makemikari chete, asiwo zvinoisawo njodzi yekukuvara kunokonzerwa nekudziya kwakanyanya. Saka, mushonga wekaburitsi wakaiswa kana uri mukuita kwekuwedzera simbi charge zvishoma nezvishoma kuti ubatanidzwe.
Sekunge kana paine huwandu hwakawanda hwekuwedzera, inogona kusanganiswa nechoto cheinduction kana iron yemvura ichipisa zvakanyanya pamwe chete nekufunga, kuve nechokwadi chekuti nguva yekunyudzwa kwesimbi yemvura muiron ye10Min, kune rumwe rutivi kuburikidza nemhedzisiro yemagetsi yekusanganisa yecarburizer yakazara nekunyudzwa, kuve nechokwadi chekuti mhedzisiro yekunyudzwa inotorwa. Kune rumwe rutivi, huwandu hwenitrogen hunounzwa mucarburizer hunogona kuderedzwa.
Usawedzera kamwe chete, wedzera muzvikamu, wozopedzisira wanyungudutsa chikamu, isa chikamu chesimbi inopisa (inenge paki) mubhegi, wozodzosera kucarburizer yefurnace ka1-2, wozoisa slag, woisa alloy.
Pane zvinhu zvakati wandei zvekutarisisa:
1. Carburizing agent inonetsa kunyudza (isina calcination);
2, kugoverwa kwezvikamu zvemadota emushonga we carburizing hakuna kufanana;
3. Kupinda kwanonoka;
4. Nzira yekubatanidza haina kunaka, uye kubatanidza kwakapetwa kunoshandiswa. Dzivisa girazi resimbi rine mvura uye tsvina yakawandisa kana yawedzerwa;
5. Edza kusashandisa zvinhu zvine ngura zvakanyanya.
Hunhu hwemushonga wepamusoro-soro we carburizing
1, saizi yechinhu ichi iri pakati nepakati, porosity yakakura, kumhanya kwekunyudzwa kwayo kunokurumidza.
2. Kuumbwa kwemakemikari akachena, kabhoni yakawanda, sarufa shoma, zvikamu zvidiki zvinokuvadza, mwero wepamusoro wekunyudzwa kwemvura.
3, chimiro chegirazi regirafiti chezvigadzirwa chakanaka, chinovandudza kugona kwesimbi yemvura yekutanga. Wedzera huwandu hwemapfundo esimbi ane maburi mukubaya, uye wedzera nucleus yegirafiti musimbi yemagetsi yemoto. Kunatsa uye kuenzana kwekupararira kweinki yefossil muma castings.
4. Kushanda zvakanaka uye kugadzikana.
Kusarudzwa kwemushonga wekaburisheni wakakodzera kunobatsira kuderedza mari yekugadzira simbi yekunyungudutsa, kuvandudza mhando yesimbi yekunyungudutsa uye simbi dzinonyungudutsa, kuitira kuti fekitari yekunyungudutsa, simbi dzinonyungudutsa
