Ho na le mekhoa e leshome e sebelisoang hangata ea ho tima lits'ebetsong tsa kalafo ea mocheso, e leng mokhoa o le mong (metsi, oli, moea) ho tima; Ho tima habeli ho mahareng; Ho tima martensite ka mekhahlelo; Ho tima martensite ka maemo ka tlase ho Ms ntlha; Bainite isothermal quenching mokhoa; Mokhoa oa ho tima o kopantsoeng; Mokhoa oa ho tima pele ho pholile oa isothermal; Mokhoa oa ho tima mohatsela o liehang; Mokhoa oa ho ikoetlisa le oa ho itšireletsa; Mokhoa oa ho tima ho fafatsa, joalo-joalo.

1、 Mokhoa o le mong (metsi, oli, moea) o tima

Mocheso o le mong (metsi, oli, moea) quenching: Ho tima lisebelisuoa tsa mosebetsi tse futhusitsoeng ho isa mochesong o timang ho li pholisa ka botlalo. Ona ke mokhoa o bonolo oa ho tima, o atisang ho sebelisoa bakeng sa tšepe ea carbon le alloy steel workpieces ka libopeho tse bonolo. Mokhoa oa ho tima o tla khethoa ho ea ka mocheso oa mocheso oa mocheso, boima, boholo, sebōpeho, joalo-joalo.

3、 Mohato quenching ea martensite Mohato quenching ea martensite: tšepe e austenitized, 'me joale qoelisoa ka seaplane mokelikeli (letsoai bate kapa alkali bath) le mocheso o phahameng hanyenyane kapa ka tlaase ho feta e ka holimo martensite ntlha ea tšepe,' me bolokoa ka nako e loketseng. . Ha likarolo tse ka hare le tse ka ntle tsa likarolo tsa tšepe li fihla mocheso o bohareng, li ntšoa bakeng sa ho pholisa moea, 'me austenite e sa pholileng e fetoha martensite butle-butle. Ka kakaretso e sebelisoa bakeng sa li-workpieces tse nyane tse nang le libopeho tse rarahaneng le litlhoko tse thata tsa deformation, mokhoa ona o boetse o sebelisoa hangata bakeng sa ho tima tšepe e phahameng ka lebelo le liforomo tse phahameng tsa tšepe. 4、 Gradeed quenching ea martensite tlase Ms ntlha ke graded quenching ea martensite tlase Ms ntlha: ha mocheso bath e ka tlaase ho feta Ms ea tšepe sebelisoa bakeng sa workpiece empa e phahameng ho feta Mf, workpiece pholile ka potlako ka bateng, 'me liphello tse tšoanang li ntse li ka khona. ho fumanwa ha boholo bo le boholo. Hangata e sebelisoa bakeng sa lisebelisoa tsa tšepe tse nang le boholo bo boholo bo tlase. 5、 Bainite isothermal quenching mokhoa Bainite isothermal quenching Mokhoa oa ho tima: tima sesebedisoa ka bateng ka mocheso o tlase oa tšepe ho isa ho isothermal, e le hore e ka kena phetohong e tlase ea bainite, 'me ka kakaretso e boloke ka bateng bakeng sa 30~60min. The bainite isothermal quenching process e na le mehato e meraro ea mantlha: ① austenitizing; ② phekolo e pholileng ka mor'a hore austenitization; ③ kalafo ea isothermal ea Bainite; Hangata e sebelisoa ka tšepe ea alloy, tšepe e phahameng ea carbon steel likarolo tse nyane, le li-castings tsa tšepe tsa ductile. 6、 Mokhoa o kopanetsoeng oa ho tima

Mokhoa oa ho tima: "workpiece" e tingoa ka tlase ho Mme ho fumana martensite e nang le karoloana ea 10% ~ 30%, ebe isothermal sebakeng se tlase sa bainite ho fumana meaho ea martensite le bainite bakeng sa lisebelisoa tse nang le likarolo tse kholo tsa sefapano, tse sebelisoang hangata lisebelisoa tsa tšepe tsa motsoako oa tšepe. 7、 Precooling Isothermal Quenching Method Precooling Isothermal Quenching Method: E boetse e tsejoa e le Temperature Rise Isothermal Quenching, likarolo li qala ho pholile ka mocheso o tlase (o moholo ho feta Ms) bate, ebe li fetisetsoa sebakeng sa ho hlapa mocheso o phahameng ho kena phetoho ea isothermal ea austenite. E loketse likarolo tsa tšepe tse nang le boima bo fokolang kapa li-workpieces tse nang le litekanyo tse kholo tse hlokang ho tima isothermal.

8、 Mokhoa oa ho tima mohatsela o liehang

Mokhoa oa ho tima pholileng o liehang ho feta: Likarolo li pholile ho fihlela mocheso o phahame hanyane ho feta Ar3 kapa Ar1 moeeng, metsi a chesang, kapa bateng ea letsoai, ebe li kenngoa ka mokhoa o le mong oa ho tima. E sebelisoa ka tloaelo bakeng sa likarolo tse nang le libopeho tse rarahaneng, tse fapaneng botenya likarolong tse fapaneng, 'me li hloka deformation e fokolang.

9 Mokhoa oa ho tima: Chesa lisebelisoa tsohle tse sebetsitsoeng, empa nakong ea ho tima, ke likarolo feela tse hlokang ho thatafatsoa (hangata likarolo tse sebetsang) li qoelisoa ka tharollo ea ho tima bakeng sa pholiso. Emela ho fihlela likarolo tse sa qoelisoang li nyamela, 'me hang-hang u li tlose bakeng sa ho pholile moeeng. Mokhoa oa ho tima le ho itšebetsa o sebelisa mocheso o sa pholisoeng ka ho feletseng ho tloha bohareng ho fetela holimo, ho etsa hore bokaholimo bo kokobele. Lisebelisoa tse atisang ho sebelisoa ho mamella tšusumetso, joalo ka lichesele, litebele, lihamore, joalo-joalo 10、 Mokhoa oa ho tima: Mokhoa oa ho tima oo metsi a fafatsoang holim'a sesebelisoa, 'me metsi a phallang a ka ba a maholo kapa a manyenyane, ho itšetlehile ka botebo bo hlokahalang ba ho tima. Mokhoa oa ho tima spray ha o thehe filimi ea mouoane holim'a sebaka sa mosebetsi, se tiisang hore ho fumanoa lera le thata ho feta ho tima metsing a Xitong. E sebedisoang haholo bakeng sa ho tima bokahodimo ba lehae.
