Nidaamka dhalaalidda, sababtoo ah qiyaasta aan habooneyn ama lacag-bixinta iyo decarbonization xad-dhaaf ah iyo sababo kale, mararka qaarkood kaarboonka ku jira birta ama birta ma buuxinayo shuruudaha la filayo, ka dibna waxaa lagama maarmaan ah in la karsado birta ama birta dareeraha ah.Maaddooyinka ugu muhiimsan ee sida caadiga ah loo isticmaalo carburizing waa budada anthracite, birta doofaarka ee karbuunta, budada electrode, budada kookaha batroolka, kookaha asphalt, budada dhuxusha iyo budada kookaha.Shuruudaha carburizer-ku waa in kaarboonka joogtada ah ee sarreeya, uu ka sii fiicnaado, oo uu hoos u dhigo maadada wasakhda waxyeelada leh sida dambaska, walxaha isbedbeddelaya iyo baaruudka, si fiican, si aanay u wasakheynin birta.
Dhalista tuurista waxay isticmaashaa recarburizer tayo sare leh ka dib markii la dubay heerkul sare ee kookaha batroolka oo leh wasakh yar, taas oo ah xidhiidhka ugu muhiimsan ee habka karburinta.Tayada recarburizer-ka ayaa go'aamisa tayada birta dareeraha ah, sidoo kale waxay go'aamisaa in saameynta garaafyada la heli karo.Marka la soo koobo, yaraynta birta dib-u-burburiyaha ayaa door muhiim ah ka ciyaara.
Marka dhammaan birta qashinka lagu dhalaaliyo foornada korantada, recarburizer-ga la sawiray ayaa la door bidaa, iyo recarburizer-ga lagu sawiray heerkulka sare wuxuu beddeli karaa atamka kaarboonka qaabkii asalka ahaa ee khalkhalsanaa una beddelo habaynta xaashida, iyo garaafyada xaashida waxay noqon kartaa tan ugu fiican. xudunta u ah nucleation garaafyada si kor loogu qaado garaafka.Sidaa darteed, waa in aan dooranaa recarburizer kaas oo lagu daaweeyay garaafaynta heerkul sare.Sababtoo ah daawaynta garaafaynta heer-kulka sare, waxa ku jira baaruuddu waxa ay dhalisaa baxsashada gaaska SO2 oo ay yarayso.Sidaa darteed, maadada baaruudda ee recarburizer tayo sare leh ayaa aad u hooseysa, guud ahaan wax ka yar 0.05%, iyo ka wanaagsan xitaa wax ka yar 0.03%.Isla mar ahaantaana, tani sidoo kale waa tilmaame aan toos ahayn oo ah in lagu daaweeyay garaafaynta heer-kulka sare iyo haddii garaafaynta ay wanaagsan tahay.Haddii recarburizer la doortay aan graphitized heerkulka sare, awoodda nucleation ee graphite si weyn u dhimay, iyo awoodda graphitization waa la wiiqay, xataa haddii xaddi isku mid ah oo kaarboon waa la gaari karaa, laakiin natiijada gabi ahaanba ka duwan.
Waxa loogu yeero recarburizer waa in si wax ku ool ah loo kordhiyo kaarboonka ku jira birta dareeraha ah 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, waxaad u baahan tahay inaad ku darto alaab ka badan kan sare. -Carbon recarburizer, kaas oo shaki la'aan kordhiya qadarka walxaha kale ee aan fiicnayn ee karburiyaha, si aanay birta dareeraha ahi si fiican u soo noqon.
Baaruud hooseeya, nitrogen iyo curiyeyaasha hydrogen ayaa fure u ah si looga hortago soo saarista daloolada nitrogen ee shubka, sidaa darteed maadada nitrogen ee recarburizer-ka ayaa looga baahan yahay inay hoos u dhigto sida ugu macquulsan.
Tilmaamayaasha kale ee recarburizer-ga, sida qadarka qoyaanka, dambaska, qulqulaya, hoos udhaca qadarka kaarboonka go'an, tirada sare ee kaarboonka go'an, sidaas darteed qadarka sare ee kaarboonka go'an, waxyaabaha ku jira qaybahan waxyeellada leh waa inaysan noqon sare
Hababka kala duwan ee dhalaalidda, noocyada foornada iyo xajmiga foornada dhalaalka, waxa kale oo muhiim ah in la doorto xajmiga qaybta saxda ah ee recarburizer, kaas oo si wax ku ool ah u wanaajin kara heerka nuugista iyo nuugista recarburizer ee birta dareeraha ah, oo iska ilaali oksaydhka iyo gubasho luminta karburiyaha oo ay sababtay cabbirka walxaha aad u yar.Xajmiga qaybtiisa ayaa ugu fiican: 100kg foornada ayaa ka yar 10mm, 500kg foornada waxay ka yar tahay 15mm, foornada 1.5 tan waxay ka yar tahay 20mm, 20 tan foornada waxay ka yar tahay 30mm.Dhalista beddelka, marka birta kaarboonka sare la isticmaalo, recarburizer ka kooban wasakh yar ayaa la isticmaalaa.Shuruudaha dib-u-carbiyaha loo isticmaalo samaynta birta-beddelaha sare ee la afuufay waa kaarboon go'an oo sarreeya, maadada hoose ee ash, kacsan iyo baaruud, fosfooraska, nitrogen iyo wasakhyada kale, iyo qalalan, nadiif ah, cabbir dhexdhexaad ah.Kaarboonkeeda go'an C≥96%, content kacsan ≤1.0%, S≤0.5%, qoyaan ≤0.5%, cabbirka qayb ee 1-5mm.Haddii xajmigu aad u fiican yahay, way fududahay in la gubo, haddii ay aad u qallafsan tahayna, waxay dul sabbaysaa birta dareeraha ah oo aanay fududayn in ay nuugaan birta dhalaalaysa.Cabbirka walxaha foornada induction ee 0.2-6mm, kaas oo birta iyo birta kale ee birta madow ee 1.4-9.5mm, birta kaarboonka sare waxay u baahan tahay nitrogen hooseeya, cabbirka walxaha 0.5-5mm iyo wixii la mid ah.Baahida gaarka ah si waafaqsan nooca foornada gaarka ah nooca workpiece dhalaalidda iyo faahfaahinta kale xukun gaar ah iyo doorashada.
