6. Hanyar quenching mahadi
Hanyar quenching mahadi: da farko quench da workpiece zuwa kasa Ms don samun martensite tare da wani juzu'i juzu'i na 10% zuwa 30%, sa'an nan kuma isotherm a cikin ƙananan bainite zone don samun martensite da bainite Tsarin for girma giciye-sashe workpieces. Ana amfani da Alloy kayan aiki karfe workpieces.
7. Precooling da isothermal quenching Hanyar
Pre-sanyi isothermal quenching Hanyar: wanda kuma ake kira dumama isothermal quenching, da sassa da aka fara sanyaya a cikin wani wanka tare da ƙananan zafin jiki (mafi girma fiye da Ms), sa'an nan kuma canjawa wuri zuwa wani wanka tare da mafi girma zafin jiki don sa austenite ya fuskanci isothermal canji. Ya dace da sassa na karfe tare da rashin ƙarfi mara ƙarfi ko manyan kayan aikin da dole ne a cire su.
8. Hanyar kwantar da hankali da jinkiri
Hanyar kwantar da jinkiri: An fara sanyaya sassan a cikin iska, ruwan zafi, ko wankan gishiri zuwa zafin jiki da ya fi Ar3 ko Ar1, sannan a yi kashe matsakaicin matsakaici. Ana amfani da shi sau da yawa don sassa masu hadaddun sifofi da kauri daban-daban a sassa daban-daban kuma suna buƙatar ƙananan nakasu.
9. Hanyar kashewa da zafin kai
Hanyar kashewa da zafin kai: Duk aikin da za a sarrafa yana mai zafi ne, amma yayin quenching, kawai ɓangaren da ake buƙatar taurare (yawanci ɓangaren aiki) ana nutsar da shi cikin ruwa mai kashewa kuma a sanyaya. Lokacin da launin wuta na ɓangaren da ba a nutse ba ya ɓace, nan da nan cire shi a cikin iska. Matsakaici tsarin kwantar da hankali. Hanyar quenching da zafin kai yana amfani da zafi daga ainihin wanda ba a sanyaya gaba ɗaya ba don canjawa wuri zuwa saman don fushi. Kayayyakin da aka saba amfani da su don jure tasiri kamar su chisels, naushi, guduma, da sauransu.
10. Hanyar kashewa
Hanyar kashewa: Hanyar kashewa wanda ake fesa ruwa akan kayan aikin. Ruwan ruwa na iya zama babba ko ƙarami, dangane da zurfin da ake buƙata na quenching. The fesa quenching Hanyar ba ta samar da wani tururi film a saman na workpiece, don haka tabbatar da zurfin taurare Layer fiye da ruwa quenching. Anfi amfani dashi don quenching na gida.
