Babban bambanci tsakanin annealing da normalizing:

1. Adadin sanyaya na al'ada yana da ɗan sauri fiye da na annealing, kuma digiri na supercooling ya fi girma.
2. Tsarin da aka samu bayan al'ada yana da kyau sosai, kuma ƙarfi da taurin sun fi girma fiye da na annealing.

Zaɓin annealing da normalizing:

1. Don ƙananan bututun ƙarfe maras sumul tare da abun ciki na carbon ƙasa da 0.25%, ana amfani da al'ada yawanci maimakon annealing. Saboda saurin sanyaya adadin zai iya hana ƙananan bututun ƙarfe maras sumul daga hazo na siminti na sakandare kyauta tare da iyakar hatsi, don haka inganta aikin nakasar sanyi na sassan stamping; normalizing zai iya inganta taurin karfe da kuma yanke aikin ƙananan bututun ƙarfe maras nauyi. ; Lokacin da babu wani tsarin kula da zafi, daidaitawa zai iya tsaftace hatsi da inganta ƙarfin ƙananan bututun ƙarfe maras nauyi.

2. Matsakaicin carbon sanyi-janye bututun ƙarfe maras sumul tare da abun ciki na carbon tsakanin 0.25% da 0.5% shima ana iya daidaita shi maimakon annealing. Ko da yake matsakaici-carbon karfe sanyi-jawo sumul karfe bututu tare da carbon abun ciki kusa da babba iyaka yana da high taurin bayan normalizing, shi ne har yanzu Ana iya yanke, da normalizing kudin ne low da yawan aiki ne high.

3. Cold-zana sumul karfe bututu tare da carbon abun ciki tsakanin 0.5 da kuma 0.75%, saboda high carbon abun ciki, da taurin bayan normalizing ne muhimmanci mafi girma fiye da na annealing, kuma yana da wuya a yi yankan aiki, don haka cikakken annealing ne. gabaɗaya ana amfani da su don rage Tauri da ingantattun injina.

4. High carbon ko kayan aiki karfe tare da carbon abun ciki> 0.75% na sanyi kõma sumul karfe bututu kullum rungumi dabi'ar spheroidizing annealing a matsayin farko zafi magani. Idan akwai siminti na biyu meshed, ya kamata a fara daidaita shi. Annealing tsari ne na maganin zafi wanda sanyin bututun ƙarfe mara nauyi ya zana zuwa yanayin zafin da ya dace, a ajiye shi na wani ɗan lokaci, sannan a sanyaya a hankali. Sannu a hankali shine babban fasalin annealing. Bututun bututun ƙarfe maras ɗin sanyi wanda aka zana sanyi gabaɗaya ana sanyaya su zuwa ƙasa da 550 ℃ tare da tanderun da aka sanyaya. Annealing magani ne da ake amfani dashi sosai. A cikin tsarin masana'antu na kayan aiki, gyare-gyare ko sassa na inji, da dai sauransu, ana shirya shi azaman maganin zafi na farko bayan yin simintin gyare-gyare, ƙirƙira da walda, kuma kafin yanke (m) sarrafa don kawar da wasu matsalolin da tsarin baya ya haifar. lahani, da kuma shirya don ayyuka na gaba.

Manufar Annealing:

① Inganta ko kawar da daban-daban tsarin lahani da kuma saura danniya lalacewa ta hanyar karfe a kan aiwatar da simintin gyaran kafa, ƙirƙira, mirgina da walda, da kuma hana nakasawa da fatattaka na workpiece;
② taushi da workpiece don yankan;
③ Tace hatsi da inganta tsarin don inganta kayan aikin injiniya na kayan aiki;
④ Shirya ƙungiyar don maganin zafi na ƙarshe (quenching, tempering).
