Sida loo doorto dib-u-caruuriyaha birta-samaynta tayada sare leh

Habka dhalaalidda, sababtoo ah dufan aan habboonayn ama ku dallacaadda iyo decarburization xad-dhaaf ah, mararka qaarkood kaarboonka ku jira birta ama birta ma buuxinayo shuruudaha la filayo.Waqtigaan, kaarboon waa in lagu daraa birta ama birta dhalaalaysa.Alaabta ugu muhiimsan ee sida caadiga ah loo isticmaalo kaarboonization waa budada anthracite, birta doofaarka ee carbonized, budada electrode, budada kookaha batroolka, coke pitch, budada dhuxusha iyo budada kookaha.Shuruudaha dib-u-carbiyeyaasha ayaa ah in kor u kaca kaarboonka go'an, si fiican, iyo hoos u dhigista maadada wasakhda waxyeelada leh sida dambaska, walxaha kacsan iyo baaruudka, si fiican, si aan loo nijaasayn birta.

Dhalista tuurista waxay isticmaashaa recarburizers tayo sare leh ka dib markii heerkulka sare ee kookaha batroolka uu leeyahay wasakh yar, taas oo ah xidhiidhka ugu muhiimsan ee habka recarburization.Tayada recarburizer-ka ayaa go'aamisa tayada birta dhalaalaysa, sidoo kale waxay go'aamisaa in saameyn garaafeed wanaagsan la heli karo.Marka la soo koobo, yaraynta yaraynta birta dhalaalaysa iyo dib-u-carburiyeyaasha ayaa door muhiim ah ka ciyaara.

Marka birta qashinka oo dhan lagu dhalaaliyo foornada korantada, recarburizer-garaafaysan ayaa la door bidaa.Daawaynta garaafka heerkulka sare ka dib, atomiyada kaarboonku waxay ka bedeli karaan habayntii asalka ahayd ee khalkhalka galay una beddelaan qaabaynta flake, iyo garaafiga flake wuxuu noqon karaa garaaf-u eg.Xudunta ugu fiican ee xudunta, si loo fududeeyo horumarinta garaafyada.Sidaa darteed, waa in aan dooranaa recarburizer kaas oo soo maray garaafaynta heerkul sare.Sababtoo ah daawaynta garaafka heerkulku sarreeyo, waxa ku jira baaruuddu waxa ay yaraynaysaa baxsashada gaaska SO2.Sidaa darteed, dib-u-carbiyeyaasha tayada sare leh waxay ka kooban yihiin maaddo baaruud ah oo aad u hooseeya, w(-yada) guud ahaan way ka yar yihiin 0.05%, iyo w(-yada) ka wanaagsan xitaa in ka yar 0.03%.Isla mar ahaantaana, tani sidoo kale waa tilmaame aan toos ahayn si loo xukumo in lagu sameeyay daawaynta garaafaynta heer-kulka sare iyo haddii garaafaynta ay wanaagsan tahay.Haddii recarburizer-ga la doortay aanu marin daawaynta heerkul sare, awoodda nukliyeerka ee garaafyada ayaa si weyn loo dhimi doonaa, awoodda garaafaynta ayaa la daciifin doonaa.Xitaa haddii qadar isku mid ah oo kaarboon ah la gaari karo, natiijadu gebi ahaanba way ka duwan tahay.
Waxa loogu yeero recarburizer waa in si wax ku ool ah loo kordhiyo kaarboonka ku jira birta dhalaalaysa ka dib marka lagu daro, markaa kaarboonka go'an ee recarburizer waa inuusan noqon mid aad u hooseeya, haddii kale si loo gaaro qayb ka mid ah kaarboonka, waxaa lagama maarmaan ah in lagu daro kaarboon aad u sarreeya. nuxurka.Muunado badan oo recarburizer ah ayaa shaki la'aan kordhin doona cadadka walxaha kale ee aan fiicnayn ee ku jira recarburizer-ka, si aanay birta dhalaalaysa u helin faa'iidooyin wanaagsan.
Baaruud hoose, nitrogen iyo curiyayaasha hydrogen ayaa fure u ah ka hortagga daldaloolada nitrogen ee ku jira shubista, sidaa darteed hoos u dhigidda maadada nitrogen ee recarburizer-ka, ayaa ka sii wanaagsan.Tilmaamayaasha kale ee recarburizer-ka, sida qoyaanka, dambaska, iyo walxaha kacsan, hoos u dhaca qadarka kaarboonka go'an, ayaa sarreeya qadarka kaarboonka go'an, sidaas darteed tirada sare ee kaarboonka go'an, waxa ku jira qaybahan waxyeellada leh waa inaysan noqon sare
Marka loo eego hababka dhalaalidda ee kala duwan, noocyada foornada iyo cabbirrada foornooyinka dhalaalka, sidoo kale waa mid aad muhiim u ah in la doorto xajmiga qaybta ku habboon ee recarburizer, kaas oo si wax ku ool ah u wanaajin kara heerka nuugista iyo nuugista birta dhalaalaysa ee recarburizer, oo iska ilaali dhibaatada cabbirka qayb yar oo xad dhaaf ah.Waxaa sababay gubashada oksaydhiyaha ee recarburizers.

Xajmiga qaybtiisa ayaa la door bidaa: 100kg foorno ka yar 10mm, 500kg foorno ka yar 15mm, 1.5 tan foornada ka yar 20mm, 20 tan foornada ka yar 30mm.Dhalista beddelka, marka birta kaarboonka sare la isticmaalo, recarburizer leh wasakh yar ayaa la isticmaalaa.Shuruudaha dib-u-carburiyeyaasha ee birta-beddelaha sare-u-afuufidu waa kaarboon go'an oo sarreeya, dambas hooseeya, kacsan iyo baaruud, fosfooraska, nitrogen iyo wasakhyada kale, qalalan, nadiif ah, iyo cabbir dhexdhexaad ah.Its kaarboon C 96% go'an, arrinta kacsan ≤ 1.0%, S ≤ 0.5%, qoyaan ≤ 0.5%, size qayb 1-5mm.Haddii xajmigu aad u fiican yahay, way fududahay in la gubo, haddii ay aad u qallafsan tahayna, waxay dul sabbaysaa birta dhalaalaysa oo aanay si fudud u nuugin birta dhalaalaysa.Foornooyinka induction, cabbirka qaybtu waa 0.2-6mm, kuwaas oo birta iyo walxaha kale ee dahabka madow ay yihiin 1.4-9.5mm, birta kaarboonka sare waxay u baahan tahay nitrogen hooseeya, cabbirkuna waa 0.5-5mm, iwm. Baahida gaarka ah waxay ku saleysan tahay. nooca foornada gaarka ah si ay u dhalaaliso workpiece ah Noocyada iyo faahfaahinta kale ee xukunka gaarka ah iyo xulashada.
