Dulmar guud oo ku saabsan habka deminta heerka-sare ee daaweynta kulaylka ee mindiyaha goynta dharka korontada
Dulmar guud oo ku saabsan habka daminta-soo noqnoqda sare ee lagu daweynayo kulaylka ee mindiyaha goynta dharka korontada
Mindi goynta maro koronto waa kulayl lagu daaweeyaa mishiin deminta soo noqnoqda. Kadib kulaylka daaweynta kulaylka ee 550 °C, waxaa loo wareejiyaa 860-880 °C dib u kululaynta daaweynta kulaylka. Heerkulka kuleylku wuu kala duwan yahay iyadoo loo eegayo darajooyinka birta ee kala duwan. 1250-1260°C, 1190-1200°C, 1200-1210°C, 1150-1160°C, siday u kala horreeyaan. Cabbirka hadhuudhka waxaa lagu xakameynayaa 10.2-11 fasal. Ugu dambeyntii, daawaynta kulaylka heerkulka 550-560 ° C ayaa la sameeyaa.
Hubi adayga ka dib marka la kululeeyo, haddii ay ka badan tahay 64HRC, waa in la kordhiyaa ilaa 580 ℃ heerkulka. Mid mid u eeg toosnaanta. Haddii dulqaadka la dhaafo, sii wad xajinta iyo xanaaqa, laakiin kulaylka lama ogola.
