Maitiro ekusarudza emhando yepamusoro steelmaking recarburizer
Mukuita kunyungudutsa, nekuda kwebhengi isina kufanira kana kuchaja uye yakawandisa decarburization, dzimwe nguva kabhoni yemukati musimbi kana simbi haizadzise zvinotarisirwa zvinodiwa.Panguva ino, kabhoni inofanira kuwedzerwa kune simbi kana simbi yakanyungudutswa.Zvinhu zvikuru zvinowanzo shandiswa kugadzira carbonization ianthracite powder, carbonized pig iron, electrode powder, petroleum coke powder, pitch coke, charcoal powder uye coke powder.Zvinodiwa kune recarburizers ndezvokuti iyo yakakwirira yakagadziriswa kabhoni yemukati, zviri nani, uye yakadzika iyo inokuvadza tsvina sedota, inovhuvhuta nyaya uye sarufa, zviri nani, kuitira kuti isasvibisa simbi.
Iko kunyungudutswa kwekukandira kunoshandisa emhando yepamusoro recarburizers mushure mepamusoro-tembiricha calcination yepetroleum coke ine mashoma tsvina, inova ndiyo inonyanya kukosha chinongedzo mukuita recarburization.Hunhu hweiyo recarburizer hunotaridza kunaka kwesimbi yakanyungudutswa, uye zvakare inosarudza kana yakanaka graphitization mhedzisiro inogona kuwanikwa.Muchidimbu, kuderedza simbi yakanyungudutswa shrinkage uye recarburizers inoita basa rakakosha.
Kana iyo yese simbi yakanyungudutswa muchoto chemagetsi, iyo graphitized recarburizer inosarudzwa.Mushure mekupisa kwepamusoro-kupisa graphitization kurapwa, maatomu ekabhoni anogona kushanduka kubva kuhurongwa hwekutanga hwakakanganisika kuenda kuhurongwa hweflake, uye flake graphite inogona kuita senge graphite.Iyo yakanakisa musimboti wepakati, kuitira kufambisa kusimudzirwa kwegraphitization.Naizvozvo, isu tinofanirwa kusarudza recarburizer iyo yakasangana nepamusoro-tembiricha graphitization.Nekuda kweiyo yakanyanya tembiricha graphitization kurapwa, iyo sulfur yemukati inoderedzwa nekupukunyuka kweSO2 gasi.Naizvozvo, emhando yepamusoro recarburizer ane yakaderera kwazvo sulfur zvirimo, w(s) kazhinji isingasviki 0.05%, uye zvirinani w(s) kunyange isingasviki 0.03%.Panguva imwecheteyo, ichi zvakare chiratidzo chisina kunanga chekutonga kana chakaitwa nepamusoro tembiricha graphitization kurapwa uye kana graphitization yakanaka.Kana iyo yakasarudzwa recarburizer isati yaitwa nepamusoro-tembiricha graphitization kurapwa, iyo nucleation kugona kwegraphite ichaderedzwa zvakanyanya, uye kugona kwegraphitization kuchaderedzwa.Kunyange kana huwandu hwekabhoni hunogona kuwanikwa, zvigumisiro zvakasiyana zvachose.
Iyo inonzi recarburizer ndeyekunyatso wedzera kabhoni yemukati musimbi yakanyungudutswa mushure mekuwedzera, saka iyo yakagadziriswa kabhoni yemukati yerecarburizer haifanirwe kunge yakadzikira, zvikasadaro kuti uwane imwe kabhoni yemukati, zvinodikanwa kuwedzera kabhoni yakakwira. content.Mamwe masampuli e recarburizer pasina mubvunzo achawedzera huwandu hwezvimwe zvinhu zvisina kunaka mune recarburizer, kuitira kuti simbi yakanyungudutswa isawane mabhenefiti ari nani.
Yakaderera sarufa, nitrogen uye hydrogen zvinhu ndiyo kiyi yekudzivirira nitrogen pores mucastings, saka iyo yakaderera iyo nitrogen yemukati yerecarburizer, zviri nani.Zvimwe zvinongedzo zveiyo recarburizer, senge mwando, dota, uye zvinhu zvinoshanduka, iyo yakadzikira iyo yakagadziriswa kabhoni, yakakwira huwandu hweyakagadziriswa kabhoni, saka iyo yakakwira iyo yakagadziriswa kabhoni, zviri mukati meizvi zvinokuvadza hazvifanirwe kuve. high.
Zvinoenderana neakasiyana nzira dzekunyungudutsa, mhando dzechoto uye saizi yezviyo zvekunyungudutsa, zvakakoshawo zvakanyanya kusarudza iyo yakakodzera particle saizi ye recarburizer, iyo inogona kunyatso kuvandudza mwero wekunyungudusa uye kunyudza mwero wesimbi yakanyungudutswa kune recarburizer, uye kudzivirira iyo dambudziko rekunyanyisa diki diki saizi.Inokonzerwa ne oxidative burnout ye recarburizers.
Kukura kwayo kwechidimbu kunonyanya kunaka: 100kg choto isingasviki 10mm, 500kg choto isingasviki 15mm, 1.5 tani choto isingasviki 20mm, 20 tani choto isingasviki 30mm.Mukushandura kunyunguduka, kana simbi yakakwira kabhoni inoshandiswa, recarburizer ine tsvina shoma inoshandiswa.Zvinodiwa zvemarecarburizers epamusoro-inofuridza inoshandura simbi yakakwira yakagadziriswa kabhoni, yakaderera dota, inovhuvhuta uye sarufa, phosphorus, nitrogen uye kumwe kusvibiswa, yakaoma, yakachena, uye ine mwero particle size.Yayo yakagadziriswa kabhoni C ≥ 96%, inoputika nyaya ≤ 1.0%, S ≤ 0.5%, unyoro ≤ 0.5%, particle size 1-5mm.Kana saizi yechikamu ichi yakanyanya kunyanyonaka, iri nyore kupisa, uye kana yakanyanya kukwasha, inoyangarara pamusoro pesimbi yakanyungudutswa uye haibatike nyore nesimbi yakanyungudutswa.Pamafuru ekupinza, saizi yechikamu i 0.2-6mm, iyo simbi uye mamwe matema egoridhe zvidimbu 1.4-9.5mm, yakakwira kabhoni simbi inoda yakaderera nitrogen, uye saizi yechikamu i 0.5-5mm, nezvimwewo. Izvo zvinodiwa zvinoenderana iyo chaiyo yevira yemhando yekunyungudutsa workpiece Mhando uye mamwe mashoko ehutongo chaihwo uye kusarudzwa.
