kutentha mankhwala carburizing
kutentha mankhwala carburizing
1. Tanthauzo: Pofuna kuonjezera carbon zili pamwamba wosanjikiza workpiece ndi kupanga ena carbon content gradient mmenemo, otsika mpweya zitsulo ndi kutenthedwa ndi kukhala otentha mu carburizing sing’anga mu carburizing ng’anjo, kotero kuti maatomu carbon. kulowa pamwamba pa workpiece, ndiyeno kuzimitsa ikuchitika. mankhwala kutentha mankhwala ndondomeko.
2. Cholinga: kuonjezera carbon zili pamwamba wosanjikiza zitsulo otsika mpweya zitsulo 0.85-1.10%, ndiyeno kuzimitsa ndi kupsa mtima pa kutentha otsika kuthetsa nkhawa ndi kukhazikika dongosolo, kotero kuti wosanjikiza pamwamba pa chitsulo ndi kuuma mkulu. (HRc56-62) , onjezerani kukana kwa mavalidwe ndi mphamvu ya kutopa. Mtima umasungabe pulasitiki yake yoyambirira ndi kulimba.
3. Ntchito: Carburizing imagwiritsidwa ntchito pazitsulo zokhala ndi mpweya wochepa monga 15Cr ndi 20Cr. Kuzama kwa carburizing wosanjikiza ndi kosiyana malinga ndi zofunikira za zigawozo, nthawi zambiri 0.2 mpaka 2 mm.
Zakuthupi ndi kuya kwa carburizing kumatha kusankhidwa molingana ndi kukula kwa workpiece ndi zofunikira zamphamvu pakupanga.
Kusankhidwa kwa kuya kwa carburized layer kuyenera kupangidwa molingana ndi zosowa zenizeni kuti mupulumutse ndalama.
Kuwonjezeka kwa kuya kwa wosanjikiza kumatanthauza kukulitsidwa kwa nthawi ya carburizing, ndipo kuya kwa giya nthawi zambiri kumapangidwa molingana ndi njira yoyeserera.
