Life and surface decarburization ofphala e potolohangke sehokelo e tobileng, haeba ka morao holim'a decarbonization, matla a spiral le ho apara ho hanyetsa ho tla fokotsa tšusumetso e tobileng ho spiral ea bophelo.Haeba carbon lera holim'a spiral tšepe phala e sa hloekang, spiral holim'a lera boima ba 'mele le ho apara ho hanyetsa tla fokotswa ka tsela e loketseng,' me thulaganyou e thatafatsa, ka lebaka la ho fetoha ha bophahamo ba modumo e bakoang ke bokaholimo ba ka ntle workpiece ho thehoa ha mapetsong.

Mokhoa oa ho thibela spiral of decarbonization, karabo ke ena:

Ho rarolla bothata ba ho tlosoa ha carbonization holim'a metsi, haholo-holo ho phekoloa bakeng sa ts'ebetso ea phekolo ea mocheso, hobane oxidation le decarbonization le spiral ke ka nako e le 'ngoe, kahoo nakong ea phekolo ea mocheso, re lokela ho leka ho boloka li-coil le moea, Sena se ntlafatsa ketsahalo ea decarburization.

Sephetho sa spiral holim'a decarbonization mecha ea litaba haholo-holo oksijene, mouoane oa metsi le carbon dioxide le likhase tse ling tsa oxidizing, ha likhase tsena le ho kopana ha spiral ho ka etsa hore ho be le oxidation le decarbonization spiral, ka hona, ho laola sebōpi le carbon dioxide carbon monoxide ratio le tsona ke tsa bohlokoa haholo.

Ha e le hantle, ha e eketsoa ho spiral forging forging furnace nitrogen protective gas nitrogen e sebetsa haholo, nitrogen e ka leleka e 'ngoe ea khase ea oxidizing, e fokotsa spiral of decarbonization phenomenon.
