Akwai hanyoyin kashe wuta guda goma da aka saba amfani da su a cikin hanyoyin magance zafi, wato matsakaici ɗaya (ruwa, mai, iska) quenching; Sau biyu matsakaici quenching; quenching na martensite; Matsakaicin quenching na martensite a ƙasan ma'anar Ms; Bainite isothermal quenching Hanyar; Hanyar quenching hade; Pre sanyaya hanyar isothermal quenching; Hanyar kashewa mai jinkiri; Hanyar kashewa da zafin kai; Hanyar kashewa, da sauransu.

1、 Matsakaicin matsakaici (ruwa, mai, iska) quenching

Matsakaici guda ɗaya (ruwa, mai, iska) quenching: Quenching workpieces waɗanda aka yi zafi zuwa quenching zafin jiki a cikin quenching matsakaici don kwantar da su gaba daya. Wannan ita ce hanya mafi sauƙi quenching, fiye da amfani da carbon karfe da gami karfe workpieces tare da sauki siffofi. Za a zaɓi matsakaicin quenching bisa ga ƙimar canja wurin zafi, ƙarfin ƙarfi, girman, siffar, da sauransu na ɓangaren.

3、 Mataki quenching na martensite Mataki quenching na martensite: karfe ne austenitized, sa'an nan kuma a nutsar da shi a cikin ruwa matsakaici (gishiri wanka ko alkali bath) tare da zafin jiki dan kadan sama ko žasa fiye da babba martensite batu na karfe, da kuma ajiye don dace lokaci. . Lokacin da yadudduka na ciki da na waje na sassan karfe sun kai matsakaicin zafin jiki, ana fitar da su don sanyaya iska, kuma austenite da ba a sanyaya ba a hankali ya canza zuwa martensite. Kullum amfani da kananan workpieces tare da hadaddun siffofi da kuma m nakasawa bukatun, wannan hanya kuma fiye amfani da quenching high-gudun karfe da kuma high gami karfe molds. 4、 Matsakaicin quenching na martensite a ƙasan Ms point yana da darajar quenching na martensite a ƙarƙashin ma'anar Ms: lokacin da zafin wanka ya yi ƙasa da Ms na ƙarfe da aka yi amfani da shi don aikin aikin amma sama da Mf, aikin aikin yana yin sanyi da sauri a cikin wanka, kuma sakamakon iri ɗaya na iya har yanzu. a samu lokacin da girman ya fi girma. Yawanci amfani da manyan-sized low hardenability karfe workpieces. 5、 Bainite isothermal quenching Hanyar Bainite isothermal quenching Hanyar: quench da workpiece a cikin wani wanka a ƙananan bainite zafin jiki na karfe zuwa isothermal, sabõda haka, zai iya jurewa da ƙananan bainite canji, kuma kullum ajiye shi a cikin wanka na 30 ~ 60min. Tsarin bainite isothermal quenching yana da matakai guda uku: ① austenitizing; ② Jiyya na kwantar da hankali bayan autnitization; ③ Bainite isothermal magani; Yawanci ana amfani da shi a cikin gami karfe, babban carbon karfe ƙananan sassa, da simintin ƙarfe na ductile. 6、 Hanyar quenching composite

Hanyar quenching mahadi: workpiece ne quenched zuwa kasa Ms don samun martensite tare da juzu'i juzu'i na 10% ~ 30%, sa'an nan kuma isothermal a cikin ƙananan bainite zone don samun martensite da bainite Tsarin ga workpieces tare da manyan giciye sassan, wanda aka saba amfani da su. gami kayan aiki karfe workpieces. 7、 Precooling Isothermal Quenching Method Precooling Isothermal Quenching Method: Har ila yau aka sani da Temperature Rise Isothermal Quenching, an fara sanyaya sassa a cikin ƙananan zafin jiki (fiye da Ms) wanka, sannan a canza shi zuwa wanka mai zafi mai zafi don yin canjin isothermal na austenite. Ya dace da sassan karfe tare da rashin ƙarfi mara ƙarfi ko kayan aiki tare da manyan girma waɗanda ke buƙatar quenching isothermal.

8、 Hanyar kashewa mai jinkiri

Hanyar kashewa mai jinkiri: An riga an sanyaya sassan zuwa yanayin zafi sama da Ar3 ko Ar1 a cikin iska, ruwan zafi, ko wankan gishiri, sannan a huda da matsakaitan matsakaici guda ɗaya. Yawanci ana amfani da shi don sassa masu hadaddun sifofi, kauri daban-daban a sassa daban-daban, kuma suna buƙatar ƙarancin lalacewa.

9, . Hanyar rage zafin kai: Zazzage duk kayan aikin da aka sarrafa, amma a lokacin quenching, kawai sassan da ake buƙatar taurare (yawanci sassan aiki) ana nutsar da su cikin maganin kashewa don sanyaya. Jira har sai sassan da ba a nutse ba sun ɓace, kuma nan da nan cire su don sanyaya a cikin iska. Hanyar quenching da yanayin zafin jiki na amfani da zafin da ba a sanyaya gaba ɗaya ta cikin ainihin don canjawa zuwa saman, yana haifar da yanayin zafi. Kayayyakin da aka saba amfani da su don jure tasiri, kamar guntu, naushi, guduma, da sauransu. 10、 Fesa quenching Hanyar: Hanyar quenching a cikin abin da ake fesa ruwa a kan workpiece, da kuma ruwan kwarara iya zama babba ko karami, dangane da ake bukata zurfin quenching. Hanyar kashewa ba ta samar da fim ɗin tururi a saman kayan aikin ba, wanda ke tabbatar da cewa an sami ƙaramin ƙarfi mai zurfi fiye da quenching a cikin ruwan Xitong. Anfi amfani dashi don quenching na gida.
