Marka hore, isticmaalka wakiilka carburizing ee habka carburizing foornada

1. Kaarboon, oo ah mid ka mid ah walxaha ugu muhiimsan ee ku jira birta shubka, way ka adag tahay in la hagaajiyo marka loo eego walxaha kale.Sababtoo ah kaarboonku aad ayuu uga cufan yahay birta dareeraha ah, waxtarka nuugista aad ayuu u hooseeyaa iyada oo aan kicin xoog leh lahayn.Sida caadiga ah ee dufanka, carbon sida waafaqsan xadka sare ee shuruudaha nidaamka, oo tixgeli habka dhalaalidda ee gubasho gubasho carbon, markaa sug ilaa kharashka birta cad, cadadka kaarboon waa asal ahaan in kala duwan ee habka, xataa wax yar ka baxsan sare ee sare. Xadka waxa kale oo loo isticmaali karaa in lagu daro xaddi yar oo qashinka (nadiif ah, qalalan) waa sahlan tahay in la soo dejiyo, foornada korontada ku dhalaalaysa kaarboonka marka loo eego hawlgalka carburizing ayaa aad uga fudud.

2. Habka quudinta

Talaabada 1: Marka hore waxaad dhigtaa qadar yar oo lacag celin ah (ama hadhaaga qadar yar oo bir dareere ah) xagga hoose ee foornada, si walxaha cusub loogu dhex geliyo birta dareeraha ah, hoos u dhig oksaydhka.

Talaabada 2: Marka hore ku dar birta qashinka ah, ka dibna ku dar wakiilka carburizing.Waqtigan xaadirka ah, barta dhalaalka ee birta dareeraha ah ayaa hooseysa, taas oo si dhakhso ah loo dhalaali karo si loo hagaajiyo dhererka heerka dareeraha, sidaas darteed wakiilka carburizing wuxuu ku dhex jiraa birta dareeraha ah.Isku-dubbaridka carburizing iyo dhalaalidda birta ma kordhiso wakhtiga dhalaalka waxayna isticmaashaa awood yar.Sababtoo ah hoos u dhigista awoodda FeO ee C way ka sarraysaa kan Si iyo Mn, luminta gubanaya ee Si iyo Mn waa la dhimi karaa iyada oo lagu daro karburiyaha heerkulka hooseeya.Isku day inaad isticmaashid bacaha baakadaha oo ay ka buuxaan walxaha carburizing foornada korontada, ha u isticmaalin qanjaruufo foornada korontada ah, si aad uga fogaato qaybo yaryar oo uu nuugo boodhka ururiyaha.

Talaabada 3: Iskaraabka qayb ayaa dhalaalay waxaana lagu darayaa kharashka soo celinta.Si loo hubiyo in wakiilka carburizing uu si buuxda u nuugay ka hor inta aan la jarin, wakhtigan, foornada korontada ee awoodda sare leh (> 600kW / t) ayaa si gaar ah muhiim u ah sababtoo ah wakhtiga loo baahan yahay dhalaalidda walxaha ayaa laga yaabaa in ka yar wakhtiga loo baahan yahay nuugista dhamaystiran karburiyaha.Isla mar ahaantaana, shaqada kicinta ee foornada korantada waa in loo isticmaalo ilaa xadka ugu badan ee habka nuugista wakiilka carburizing.

Tallaabada 4: Haddii heerka soo kabashada ee wakiilka carburizing iyo xakamaynta kaarboonka ee birta dareeraha ah ayaa hubaal ah, wakiilka carburizing waxaa lagu dari karaa qashinka hal mar. Haddii aan la hubin waxay ka tagi kartaa 5% ~ 10% wakiilka carburizing si uu ugu biiro laba jeer.Ku darida labaad ee wakiilka carburizing waa kaarboon-habboon (ama kaarboon gubtay), waa in lagu daraa ka dib dareeraha birta, ka hor inta aan lagu biirin dareeraha dusha sare ee birta ee nadiifka ah, ilaa inta suurtogalka ah si looga fogaado wakiilka carburizing ee ku lug leh slag, ka dibna koronto awood sare leh iyadoo la isticmaalayo foornada korontada ku shaqeysa kicinta si loo hagaajiyo heerka nuugista.

Talaabada 5: Ku dar ferrosilicon iyo alloys kale, falanqayn muunad, hagaajin halabuurka, ka soo bax foornada.Iska ilaali inaad ku kaydiso birta dareeraha ah heerkul sare muddo dheer.Kaydinta muddada-dheer ee birta dareeraha ah heerkulka sare (gaar ahaan dahaarka muddada-dheer ee ka sarreeya 1450 ℃) waa sahlan tahay in ay horseeddo oksaydhka kaarboonka, korodhka maadada silikoon (silicon dioxide waa la dhimay) iyo luminta nuclei crystal ee birta dareeraha ah. .

Labo, isticmaalka wakiilka carburizing ee habka baakadaha xirmada

Haddii ay lagama maarmaan tahay in lagu karsado baakadka, xajmiga walxaha 100 ~ 300 ujeedka wakiilka carburizing waxaa lagu dhejin karaa gunta hoose ee xirmada, iyo birta dareeraha heerkulka sare ayaa si toos ah loogu daadiyaa wakiilka carburizing (ama lagu daro birta dareeraha ah. socodka), birtana si buuxda ayaa loo kiciyay ka dib kala dirida iyo nuugista kaarboonka.Saamaynta carburizing ee xirmada ma aha mid u fiican sida foornada, iyo heerka nuugista way adag tahay in la xakameeyo.Iyadoo aan loo eegin isticmaalka wakiilka carburizing ama habka carburizing waa in lagu go'aamiyaa iyada oo loo marayo habka tijaabada wax soo saarka iyo habka nuugista marka la go'aamiyo, si fudud ha u bedelin nooca wakiilka carburizing iyo asalka, haddii aad rabto inaad bedesho waa in ay gudubtaa xaqiijinta wax soo saarka. mar kale.
