Hababka looga hortago decarburization oksaydhiyaha ee workpieces foornada korontada tijaabo ah
Hababka looga hortago decarburization oksaydhiyaha ee foornada korontada ee tijaabada ah workpieces
1. koollada dahaarka dusha sare
Habka koollada dahaarka dusha sare ee workpiece waa yar yahay ee kharashka, hawl fudud, oo uma baahna qalab gaar ah.
Inkasta oo habka loo isticmaalo koollada uu yahay mid fudud oo ku habboon, waxaa jira khatar ah dildilaaca iyo diirinta koollada inta lagu jiro habka kuleylka, taas oo laga yaabo inay weli keento oksaydhka maxalliga ah iyo decarburization. Isla mar ahaantaana, koollada ayaa ka jira dusha sare ee shaqada, taas oo saameyn doonta tayada deminta, iyo shaqada la demiyo ma fududa in la nadiifiyo. Iyo, qaybta shaqada ee lagu daboolay koollada ayaa dhalin doonta qiiq badan marka la kululeeyo, taas oo saameyn doonta isticmaalka foornada korontada.
2. Daboolista budada dhuxusha
Isticmaal budada dhuxusha, ama ku dar qadarka saxda ah ee feylasha birta ah iyo slag (xajmiga hadhuudhka 1 ~ 4mm) budada dhuxusha sida wakiilka ilaalinta, dabool shaqada oo kuleyli foornada, taas oo si wax ku ool ah uga hortagi karta shaqada ka soo horjeeda falcelinta decarburization. Habkani waa mid sahlan oo sahlan in la hirgeliyo, kharashkuna waa yar yahay, laakiin wakhtiga kuleylka ayaa loo baahan yahay in si habboon loo kordhiyo.
3. Ka-hortagga qalabka shaqada ee qaabka gaarka ah
Qaar ka mid ah qaybaha shaqada ee qaabaysan, way adag tahay in laga hortago decarburization oksaydhative by daahan koollada ama daahan budada dhuxusha. Waqtigaan, qadar gaar ah oo budada dhuxusha ah ayaa lagu dhejin karaa foornada oo leh saxan, ka dibna heerkulka foornada ayaa la kordhin karaa heer sare. Heerkulka wuxuu u baahan yahay inuu ka sarreeyo 30 ~ 50 ℃, sidaas darteed dhuxushu waxay la falgashaa hawada si ay u dhaliso qadar ku filan oo kaarboon ah, si gaaska foornada uu ku jiro xaalad dhexdhexaad ah, ka dibna qaybo gaar ah ayaa la soo dhejiyaa, taas oo yareyn karta ama ka hortagga ifafaale decarburization oksaydhiyaha.
