Recarburizerbir-samaynta dib-u-carbiyaha (heerka warshadaha birta ee birta ah ee Jamhuuriyadda Dadka Shiinaha, YB/T 192-2001 birta samaynta recarburizer) iyo birta dib-u-carbiyaha, iyo qaar ka mid ah agabka kale ee lagu daray ayaa sidoo kale faa'iido u leh dib-u-carbiyaha, sida suufka biriiga ee lagu daro, Recarburizer-ku waxa iska leh birta-samaynta dibadda, birta-samaynta recarburizer alaabta ceeriin.

Isticmaalka wakiilka kaarboon:

In geeddi-socodka dhalaalidda, ay sabab u tahay Dufcaddii aan habboonayn ama dallacaadda iyo decarburization xad-dhaaf ah iyo sababo kale, mararka qaarkood sababa in content birta carbon ma buuxin shuruudaha muddada ugu sarreysa, ka dibna si carburization steel dareere ah. Caadi ahaan loo isticmaalo wakiilka carburizing carburizing birta doofaarka, electrode. budada, batroolka kookaha budada, budada dhuxusha iyo kookaha budada kookaha , kacsan, baaruud, fosfooraska, nitrogen iyo wasakh kale, engegan, nadiif ah, iyo cabbirka qayb dhexdhexaad ah.

Kooxda kaarboonka ee go'an ayaa loo qaybiyaa:

w(C)>96%, walxo isbedbeddelaya ≤1.0%, W (S)≤0.5%, W (qoyaanka)≤0.55%, cabbirka walxaha 1 ilaa 5mm.

Haddii cabbirka qaybuhu aad u fiican yahay, way fududahay in la gubo.Haddii ay tahay mid aad u qallafsan, waxay ku dul sabaynaysaa dusha sare ee birta dhalaalaysa mana fududa in lagu nuugo birta dhalaalaysa. Wixii cabbirka walxaha foornada induction ee 0.2-6mm, birta iyo cabbirka walxaha kale ee birta madow ee 1.4-9.5mm , Birta kaarboon sare u baahan nitrogen hoose, size qayb in 0.5-5mm, iyo wixii la mid ah baahida gaarka ah si waafaqsan nooca workpiece dhalaalaysa foornada gaarka ah iyo wixii la mid ah faahfaahinta xukunka gaarka ah iyo doorashada.

1, Habka galinta foornada:

Recarburizer wuxuu ku habboon yahay inuu ku dhalaaliyo foornada induction, laakiin isticmaalka gaarka ah maaha mid la mid ah marka loo eego shuruudaha habka.

(1) isticmaalka recarburizer ee soo noqnoqda dhexdhexaadka ah ee foornada korontada ku dhalaalaysa, marka loo eego saamiga ama shuruudaha u dhigma kaarboonka oo leh walxaha lagu daro qaybta hoose ee foornada korontada, heerka soo kabashada wuxuu gaari karaa in ka badan 95%;

(2) haddii la'aanta hagaajinta kaarboonka, darsinka ugu horreeya ee foornada saafiga ah, oo lagu daray carburant, iyadoo kor loo qaadayo heerkulka birta dhalaalaysa, ama walaaqaya elektromagnetic macmal ah si loo milo nuugista kaarboon, heerka soo kabashada waa qiyaastii 90%, haddii heerkulka hooseeya Habka carbonization, kharashka foornada dhalaalaysa kaliya qayb ka mid ah dareeraha birta dhalaalaysa ee hoos yimaada xaaladda heerkulka hooseeya, dhammaan recarburizer hal mar birta dareeraha ah, Isla mar ahaantaana, waxaa lagu cadaadiyaa birta dhalaalaysa oo leh lacag adag si aysan u dhicin. Soo bandhig dusha sare ee birta dhalaalaysa. Habkan, karburinta birta dareeraha ah waxay gaari kartaa in ka badan 1.0%.

2, ka baxsan foornada carburizing:

(1) ku buufi budada garaafka ee bacda

Isticmaalka budada graphite sida recarburizer, mugga duritaanka waa 40kg/t, iyo content ka carbon ee birta dareere ah ayaa la filayaa in ay ka korodho 2% ilaa 3%. 1299 ℃.Jet graphite budada carburization, guud ahaan loo isticmaalo nitrogen sida side, laakiin xaaladaha wax soo saarka warshadaha, hawada cadaadisku waa ka badan oo ku haboon, iyo gubasho oxygen ee hawada cadaadisay si ay u soo saaraan CO, kulaylka falcelinta kiimikada magdhabi kara qayb ka mid ah hoos u dhaca heerkulka, iyo CO dhimista jawiga si loo hagaajiyo saameynta carburization.

(2) isticmaalka recarburizer marka birta

100-300 ujeeddooyinka carburizer budada graphite waxaa lagu ridi karaa bacda, ama laga bilaabo taangiga birta ee qulqulka, ka dib markii dareeraha birta si buuxda u walaaqay, ilaa inta suurtogalka ah si loo milo nuugista kaarboon, heerka soo kabashada ee kaarboonku waa qiyaastii 50% .

Loo isticmaalo shubista, birta shubka, birta shubka, kabka waxay yeelan doontaa shuruud looga baahan yahay kaarboon, kaarburant sida magaciisa ka muuqata waa in la kordhiyo kaarboonka ku jira birta dareeraha ah, iyo, tusaale ahaan, sida caadiga ah loo isticmaalo kharashka foornada dhalada ee birta doofaarka, qashinka. birta, dib loogu celiyo kharashka foornada, kaarboonka birta ah ayaa sarreeya, laakiin qiimaha iibka qashinka ah waa qayb ka sarreeya, markaa kordhi sahayda qashinka, yareyso tirada birta shubka, Kordhinta recarburizer waxay yarayn kartaa qiimaha shubista ilaa xad.
