Recarburizeryekugadzira simbi ine recarburizer (ferrous metallurgy industry standard yePeople's Republic of China, YB/T 192-2001 steelmaking ine recarburizer) uye simbi yakakandwa ine recarburizer, uye zvimwe zvimwe zvinhu zvakawedzerwa zvinobatsirawo kudzoreredza, senge brake pad ine additives, semidziyo yekukwesha.Recarburizer ndeyekunze kugadzira simbi, ironmaking recarburizer raw materials.High quality recarburizer chinhu chinokosha chekuwedzera mukugadzira simbi yemhando yepamusoro.

Kushandisa carbon agent:

Mukuita kunyungudutsa, nekuda kwekutadza kubheta kana kubhadharisa uye yakawandisa decarburization uye zvimwe zvikonzero, dzimwe nguva zvakakonzerwa musimbi kabhoni yemukati haina kusangana nezvinodiwa zvenguva yepamusoro, ipapo kune yemvura simbi carburization.Inowanzo shandiswa carburizing agent carburizing yenguruve iron, electrode hupfu, petroleum coke powder, charcoal powder uye coke powder.Converter smelting medium and high carbon steel, kushandiswa kwepetroleum coke ine tsvina shoma se carburizing agent.Zvinodiwa recarburizer for top blown converter steelmaking i high fixed carbon, low content of ash , volatiles, sulfur, phosphorus, nitrogen nezvimwe zvitsvina, yakaoma, yakachena, uye ine mwero particle size.

Iyo yakagadziriswa kabhoni boka rakakamurwa kuita:

w (C)> 96%, nyaya inoputika ≤1.0%, W (S) ≤0.5%, W (unyoro) ≤0.55%, particle size ye1 kusvika ku5mm.

Kana iyo particle size yakanyanya kunaka, zviri nyore kupisa.Kana yakanyanya kukora, inoyangarara pamusoro pesimbi yakanyungudutswa uye haisi nyore kutorwa nesimbi yakanyungudutswa.Pakukura kwechikamu chechoto chekupinza mu 0.2-6mm, simbi uye humwe hukuru hwesimbi nhema mu1.4-9.5mm , yakakwira kabhoni simbi inoda yakaderera nitrogen, particle saizi mu 0.5-5mm, uye zvichingodaro pane chaiyo inodiwa zvinoenderana nechoto chainyungudutsa workpiece mhando uye zvichingodaro pamusoro peiyo chaiyo kutonga uye kusarudzwa.

1, nzira yekupinda muchoto:

Recarburizer inokodzera kunyungudutswa muchoto chemukati, asi iyo chaiyo yekushandisa haina kufanana zvinoenderana nezvinodiwa nemaitiro.

(1) kushandiswa kwerecarburizer mune yepakati frequency yemagetsi muchoto kunyunguduka, zvinoenderana nechiyero kana kabhoni yakaenzana zvinodiwa nechinhu chakawedzerwa kune chikamu chezasi chevira remagetsi, chiyero chekudzoreredza chinogona kusvika kupfuura 95%;

(2) kana kushaikwa kwekabhoni kugadziridzwa, gumi nemaviri ekutanga net choto slag, pamwe necarburant, nekusimudza tembiricha yesimbi yakanyungudutswa, kana artificial electromagnetic inomutsa kunyungudutsa kabhoni absorption, chiyero chekudzoreredza chinenge 90%, kana yakaderera-tembiricha. carbonization process, iyo yakanyunguduka choto inochaja chikamu chete chemvura yakanyungudutswa pasi pemamiriro ekupisa kwakadzika, zvese zvinodzoreredza kamwe-kamwe musimbi yemvura, Panguva imwecheteyo, inotsikirirwa musimbi yakanyungudutswa ine chaji yakasimba kuti isaite. fumura pamusoro pesimbi yakanyungudutswa.Nenzira iyi, iyo carburization yesimbi yemvura inogona kusvika kupfuura 1.0%.

2, kunze kwechoto carburizing:

(1) pfapfaidza graphite poda mubhegi

Uchishandisa graphite poda se recarburizer, vhoriyamu yejekiseni i40kg/t, uye kabhoni yesimbi yemvura inotarisirwa kuwedzera kubva pa2% kuenda pa3%.Tembiricha yesimbi yakanyungudutswa isati yaitwa carburization yaive 1600 ℃, uye avhareji tembiricha mushure mecarburization yaive. 1299 ℃.Jet graphite poda carburization, kazhinji inoshandisa nitrogen semutakuri, asi pasi pemamiriro ekugadzirwa kwemaindasitiri, nemhepo yakamanikidzwa iri nyore, uye kupisa kweokisijeni mumhepo yakamanikidzwa kuburitsa CO, kemikari inopisa kupisa inogona kubhadhara chikamu chekudonha kwekushisa, uye CO inoderedza mamiriro ekunze kuvandudza mhedzisiro yecarburization.

(2) kushandiswa kwe recarburizer kana iron

100-300 zvinangwa zve graphite poda carburizer inogona kuiswa mubhegi, kana kubva mutangi resimbi nekuyerera mukati, mushure meiyo simbi yemvura yamutswa zvizere, sekugona kunyungudutsa carbon absorption, iyo yekudzoreredza kabhoni ingangoita 50% .

Inoshandiswa kukanda, simbi yakakandwa, simbi yakakandwa, yakakandwa ichave nezvinodiwa zvekabhoni, carburant sezvinoreva zita rayo kuwedzera kabhoni yemukati musimbi yemvura, uye, semuenzaniso, inowanzoshandiswa mukunyungudutsa choto kubhadharisa simbi yenguruve, zvimedu. simbi, kudzoka kuchoto chekuchajisa, iron kabhoni yemukati yakakwira, asi mutengo wekutenga zvimedu wakakwira chikamu, saka wedzera kupihwa kwezvirasa, kuderedza huwandu hwesimbi yakakandwa, Kuwedzerwa kwerecarburizer kunogona kuderedza mutengo wekukanda kusvika pamwero wakati.
