Waxyaabaha saameeya haynta wakhtiga shaqada ee foornada korontada ee tijaabada ah

1. kulaylka heerkulka

Xaaladaha caadiga ah, xogta la taaban karo ayaa inta badan loo isticmaalaa xisaabinta foornooyinka korontada ee tijaabada ah. Tusaale ahaan, birta kaarboon waxaa badanaa lagu xisaabiyaa 1min/1mm, halka birta alloy ay 1.3 ilaa 1.8 jeer ka tahay birta kaarboonka. Sababta ayaa ah in birta daawadu ay leedahay maaddo sare oo ah walxaha alloying. Laakiin heerkulka sare (1000 ℃), haddii dhumucda waxtarka leh ay weyn tahay, xadka hoose ee iskudhafkan ayaa la isticmaalayaa, xadka sare ee dhumucda waxtarka leh waa mid yar.

2. Kala duwanaanshaha darajooyinka birta

Birta kaarboonka iyo birta aluminiumka ah ee hooseeya, waqtiga loo baahan yahay kala dirida carbides iyo homogenization of austenite waa mid aad u gaaban, sidaas darteed marka loo eego xaaladda, “eber” ilaalinta kulaylka ayaa loo isticmaali karaa, taas oo gaabin karta wareegga habka waxayna yareyn kartaa dildilaaca Quenching. Birta daawaha sare leh, kulaylinta deminta iyo wakhtiga haynta waa in si habboon loo kordhiyo si loo hubiyo kala dirida iyo hagaajinta carbides. Waxa lagu qiyaasi karaa 0.5 ilaa 0.8min halkii millimitir ee wakhtiga haynta. Marka xadka sare ee heerkulka deminta uu yahay 0.5min, heerkulka damintu wuxuu ku xiran yahay Qaado 0.8min xadka hoose.
