Mashiinka qallafsan ee duubista

Daawaynta kulaylka ee duubabka shaqada ee duuban waxay badiyaa qabataa deminta & heerkulka hoos u dhaca, hababka deminta sida deminta dusha sare ee induction iyo deminta kuleylka isku dhafan. Ujeedada ayaa ah in la hagaajiyo caabbinta xidhashada iyo iska caabinta diirka ee duubka. Duubka kulul wuxuu inta badan ka shaqeeyaa jawi heerkul sarreeya oo ah 700-800 ° C, dusha sarena wuxuu u baahan yahay inuu u adkeysto khilaafka xooggan ee alaabta duuban iyo kuleyliyaha soo noqnoqda, iyo sidoo kale daalka kulaylka sababtoo ah isbeddelka weyn ee heerkulka qaboojinta ee biyo qaboojin. Ka dib horumarinta duubabka kulul, birta-chromium-sare ee birta-xawaaraha sare-sare iyo birta-xawaaraha sare ayaa loo doortay qalabkooda.
