Isticmaalka Recarburizer

1. Habka gelinta foornada:

Recarburizer-ku wuxuu ku habboon yahay in lagu dhalaaliyo foornada induction, laakiin isticmaalka gaarka ah maaha mid la mid ah marka loo eego shuruudaha habka.
(1) Isticmaalka recarburizer ee dhexdhexaadinta foornada korontada ee dhexdhexaadka ah waxaa lagu dari karaa qaybaha dhexe iyo hoose ee foornada korontada iyadoo loo eegayo saamiga ama shuruudaha u dhigma kaarboon, iyo heerka soo kabashada wuxuu gaari karaa in ka badan 95%;
(2) birta dhalaalaysa haddii qadarka kaarboonku ku filnaado in lagu hagaajiyo wakhtiga kaarboonka, marka hore nadiifi dhalaalka foornada, ka dibna ku dar recarburizer, iyada oo loo marayo kuleylka dareeraha birta, walaaqaya elektromagnetic ama walaaqin macmal ah si loo milo nuugista kaarboonka, heerka soo kabashada waxay noqon kartaa oo ku saabsan 90, haddii habka carburizing heerkulka hoose, taas oo ah, kharashka kaliya dhalaali qayb ka mid ah heerkulka birta dhalaalaysa waa yar yahay, dhammaan wakiilka carburizing waxaa lagu daraa birta dareere ah hal mar.Isla mar ahaantaana, waxaa lagu riixaa dareeraha birta oo leh lacag adag si aysan u soo bandhigin dusha dareeraha birta.Carburization ee birta dareeraha ah ee habkan waxay gaari kartaa in ka badan 1.0%.

2. Gawaarida foornada oo ka baxsan:

(1) Xirmooyinka waxaa lagu buufiyaa budada garaafka, budada graphite waxaa loo isticmaalaa dib-u-kicinta, qadarka afuufkuna waa 40kg/t, kaas oo la filayo inuu kordhiyo kaarboonka birta dareeraha ah 2% ilaa 3%.Marka maadada kaarboonka ee birta dareeraha ah ay si tartiib tartiib ah u korodhay, heerka isticmaalka kaarboonku wuu yaraaday.Heerkulka birta dareeraha ah ka hor carburization wuxuu ahaa 1600 ℃, celceliska heerkulka kaarburization ka dib wuxuu ahaa 1299 ℃.Carburization budada Graphite, guud ahaan isticmaalka nitrogen sida side, laakiin xaaladaha wax soo saarka warshadaha, hawada cadaadisku waa mid aad u habboon, iyo ogsijiinta ee gubashada hawada cadaadisay si ay u soo saaraan CO, kulaylka falcelinta kiimikada magdhabi kara qayb ka mid ah heerkulka hoos u dhaca, iyo CO dhimista. jawigu wuxuu ku habboon yahay hagaajinta saameynta carburization.
(2) Isticmaalka recarburizer marka birta, waxay noqon kartaa 100-300mesh graphite budada recarburizer galay baakadka, ama ka weel birta la socodka galay, ka dib markii dareeraha birta si buuxda u walaaqay, ilaa inta suurtogalka ah si ay u milaan nuugista carbon, carbon heerka soo kabashada ilaa 50%.
