Dejinta iyo xanaaqa, taas oo ah habka daaweynta kulaylka ee sida caadiga ah lagu fuliyo marxaladda ugu dambeysa ee gabagabada, ayaa go'aamisa sifooyinka farsamada sare.
Sahayda JINDALAIQabow Shaqeyn, Dufan kulul iyo Bir been abuur ah oo loogu talagalay Deminta iyo Heerarka siinta xalal sahayda la habeeyey oo ku salaysan tilmaamo iyo shuruudo kale oo gaar ah si loo daboolo baahida macmiil kasta marka la eego darajooyinka iyo muuqaallada.Shirkadeena, oo leh 10laan-xafiisyadagudahaShiinahaiyo awood qaybin sannadkii oo dhan 200,000 Ton, waa lamaanaha ugu fiican ee balaadhinaya ganacsigaaga.
Waa maxay Quench & Steel
Dhammaan birta waxay ka kooban tahay xoogaa kaarboon ah, taas oo ka dhigaysa mid adag.Kaarboonka badan wuxuu wiiqi karaa daacadnimada birta.Habka deminta iyo xanaaqa ayaa loo isticmaalaa si loo kordhiyo sifooyinka farsamada ee birta kaarboon iyada oo aan lagu darin kaarboon badan.
Birta kaarboon-sare waxay leedahay saamiga kaarboonka 0.60 ilaa 1.00% marka la barbar dhigo saamiga 0.05 ilaa 0.25% ee birta khafiifka ah.Marka birta-kaarboon-ku-sare ay marto habka deminta iyo xanaaqa, sifadeeda makaanikada waxay ka dhigtaa mid adkaysi u leh oo waarta.
Habkani waxa kale oo uu soo bandhigaa kaydka birta qaboojinta degdega ah (deminta) iyo dib u kululaynta iyada oo hab tartiib tartiib ah loo qaboojinayo (xanaajinta).Labada habraac ee deminta iyo xanaaqa ayaa mas'uul ka ah inay ku kordhiyaan xoogga iyo adkaanta birta.
Tallaabooyinka habraaca For Qhurin iyoTboqortooyo
Si loo saameeyo adkaanta iyo xoogga birta, daaweyn kulayl gaar ah, oo loo yaqaan deminta iyo xanaaqa, ayaa la sameeyay.Quensching iyo xanaaqa waxaa loo qaybin karaa saddex tallaabo oo aasaasi ah:
AIsticmaalka → kuleylinta korka khadka GSK ee gobolka austenite
Quenching → qaboojin degdeg ah oo ka hooseeya γγ-αα-isbeddelka
Tempering → dib u kululaynta ilaa heerkul dhexdhexaad ah oo leh qaboojin tartiib ah
