Mekhatlohomokhoa oa ho qapa, kalafo mocheso ke sehokelo bohlokoa ka ho fetisisa, mocheso kalafo kaba annealing, normalizing, quenching le tempering dithulaganyo tse 'nè tsa motheo, ka tloaelo ho tsejoa e le tšepe mocheso kalafo ya "tse nne mollo".

e 'ngoe, kalafo ea mocheso oa tšepe ea mollo - ho koala:
1, annealing ke ho futhumatsa workpiece ho mocheso o loketseng, ho ea ka thepa le boholo ba workpiece ho sebelisa nako e fapaneng ea ho tšoara, ebe o lieha ho pholisa, sepheo ke ho etsa hore mokhatlo o ka hare oa tšepe o fihle kapa o haufi le boemo ba tekano, ho fumana. ts'ebetso e ntle ea ts'ebetso le ts'ebetso, kapa bakeng sa ho tima hape bakeng sa ho lokisoa ha lisele.
2, morero oa ho anneal:

① Ho ntlafatsa kapa ho felisa tšepe ts'ebetsong ea ho lahla, ho fereka, ho roala le ho cheselletsa ho bakoang ke mefokolo e fapaneng ea mokhatlo le khatello e setseng, ho thibela ho senyeha ha sesebediswa, ho phatloha.

② Nolofatsa mosebetsi oa ho seha.

③ Hloekisa lijo-thollo le ho ntlafatsa sebopeho ho ntlafatsa thepa ea mochini oa workpiece. (4) Lokisetsa phekolo ea ho qetela ea mocheso (ho tima, ho futhumatsa).
Tse peli, phekolo ea mocheso oa tšepe ea mollo oa bobeli - ho tloaeleha:
1, normalizing ke ho futhumatsa workpiece ho mocheso o loketseng ka mor'a ho pholile moeeng, phello ea normalizing e tšoana le annealing, empa mohaho o motle, o atisa ho sebelisoa ho ntlafatsa ts'ebetso ea lisebelisoa, empa hape ka linako tse ling e sebelisetsoa likarolo tse ling. ka litlhoko tse tlase joalo ka kalafo ea ho qetela ea mocheso.
2, sepheo sa ho tloaeleha:
① E ka felisa sebopeho sa lijo-thollo tse chesang haholo le sebopeho sa li-widnell tsa likarolo tsa ho lahla, tsa forging le welding, le sebopeho se tlanngoeng ka har'a thepa e roalang; Ntlafatso ea lijo-thollo; 'Me e ka sebelisoa e le phekolo ea pele ho mocheso pele e tima.
② E ka felisa cementite ea bobeli ea marang-rang, 'me ea hloekisa pearlite, eseng feela ho ntlafatsa thepa ea mochine, empa hape e thusa nakong e tlang ea spheroidizing annealing.
③Semente ea mahala moeling oa lijo-thollo e ka tlosoa ho ntlafatsa ts'ebetso e tebileng ea ho taka.
Tse tharo, phekolo ea mocheso oa tšepe ea mollo oa boraro - ho tima:
1, quenching ke ho futhumatsa workpiece ka mor'a ho boloka mocheso, ka metsing, oli kapa matsoai a mang a sa tsitsang, tharollo ea metsi a manyolo le pholileng e meng ea ho tima ka potlako. Ka mor'a ho tima, tšepe e ba thata, empa ka nako e ts'oanang e fetoha brittle.
2. Sepheo sa ho tima:
① Ntlafatsa thepa ea mochini ea lisebelisoa tsa tšepe kapa likarolo. Ka mohlala: ntlafatsa ho thatafala le ho roala ho hanyetsa ha lisebelisoa, li-bearings, joalo-joalo, ntlafatsa moeli o tsitsitseng oa liliba, ntlafatsa thepa e pharaletseng ea likarolo tsa shaft, joalo-joalo.
②, ntlafatsa thepa ea thepa kapa lik'hemik'hale tsa tšepe e itseng e khethehileng. Joalo ka ho ntlafatsa ho hanyetsa ha kutu ea tšepe e sa hloekang, eketsa magnetism e sa feleng ea tšepe ea tšepe, jj.
Tse 'nè, phekolo ea mocheso oa tšepe ea mollo oa bone - ho futhumatsa:
1, tempering e le ho fokotsa brittleness ea tšepe, ho tima tšepe ka mocheso o itseng o loketseng ka holim'a mocheso oa kamore le ka tlase ho 710 ℃ ka nako e telele, ebe ho pholile, mokhoa ona o bitsoa tempering.
2, sepheo sa ho futhumatsa:
①, ho fokotsa khatello ea maikutlo le ho fokotsa bofokoli, ho na le khatello ea maikutlo e ngata le bofokoli ba likarolo tse timang, joalo ka ho se bebofale ka nako hangata ho hlahisa deformation esita le ho phatloha.
② Fetola sebopeho sa mochini oa mosebetsi. Ka mor'a ho tima, workpiece e na le boima bo phahameng le brittleness. E le ho finyella litlhoko tse fapaneng tsa ts'ebetso ea li-workpiece tse fapaneng, ho thatafala, matla, polasetiki le ho thatafala ho ka fetoloa ka ho futhumatsa.
③, tsitsisa boholo ba workpiece. Ka ho futhumatsa, sebopeho sa metallographic se ka tsitsisoa ho netefatsa hore deformation e ke ke ea etsahala ts'ebetsong ea ts'ebeliso e tlang.
④, ntlafatsa ts'ebetso ea tšepe ea alloy e itseng.
