Uvavanyo lwe-decarburization yeebholithi

Kubalulekile ukuba umzi-mveliso ube nomatshini wovavanyo onokuvavanya ukuba ngabaiibholiti zamandla aphezulu zenziwa decarburized

1, Intshayelelo yovavanyo lwe-decarburization yeebholithi

Uvavanyo lwe-Bolt decarburization yindlela yokuvavanya kunye nokuhlola izixhobo zetsimbi, ngakumbi ukufumanisa ukuba kukho i-decarburization phenomenon kumphezulu weebholiti kunye namanye amalungu afanayo. I-Decarbonization yinto yokunciphisa i-carbon okanye ukunyamalala kwiindawo zetsimbi, ezinokuthi zibe nempembelelo enkulu ekusebenzeni kwezixhobo. Ke ngoko, uvavanyo lwe-bolt decarburization lubalulekile ukuqinisekisa umgangatho wemveliso kunye nokhuseleko.

2, Amaxabiso asemgangathweni ovavanyo lwe-bolt decarburization

Ixabiso eliqhelekileyo lovavanyo lwe-bolt decarburization ikakhulu libhekisa kubunzulu be-decarburization obuchazwe kwimigangatho efanelekileyo. Ngokwezinto ezahlukeneyo kunye neemfuno zesakhiwo, amaxabiso asemgangathweni ovavanyo lwe-bolt decarburization nawo ayahluka. Umzekelo, GB/T 6178-2006 "Ibakala eliqhelekileyoiibholiti zehexagon kunye namandongomane" imisela ukuba kwindawo yovavanyo oluchaziweyo lwebholithi, ubunzulu be-decarburization kumphezulu webholithi akufunekanga bugqithe kwi-10% yobude bomsonto.

3, Umda wokusetyenziswa kwamaxabiso asemgangathweni wovavanyo lwe-bolt decarburization

Umda wokusetyenziswa kwamaxabiso asemgangathweni wovavanyo lwe-decarburization yeebholithi kubandakanya iibholithi zentsimbi ezahlukeneyo, njengentsimbi, i-aluminium, i-nickel alloys, njl. njl. Kumsebenzi osebenzayo, kuyafuneka ukuba ukhethe iindlela ezifanelekileyo zokuvavanya i-bolt decarburization kunye namaxabiso asemgangathweni ngokusekwe kwimeko ethile yeebholiti.

4. Inkqubo yokusebenza yovavanyo lwe-bolt decarburization

Inkqubo yokusebenza yovavanyo lwe-bolt decarburization yahlulwe ngamanyathelo amathathu alandelayo:

1. Khetha indawo yokuvavanya kunye nokucoca ibholithi: Khetha indawo yovavanyo echaziweyo, coca indawo yebholithi, kwaye uqinisekise ukucoceka.

2. Ukufudumeza kunye nokupholisa: Fudumeza ibholiti kwiqondo lokushisa eliphezulu le-270 ° C-300 ° C kwiiyure ezingama-3-4, uze uyicime kwioli kwaye uyipholise kakuhle kwiqondo lokushisa.

3. Ukulinganisa ubunzulu be-decarburization: Sebenzisa izixhobo ezifana ne-optical microscope okanye i-metallographic microscope ukulinganisa ubunzulu be-decarburization kumphezulu webholithi kwindawo yovavanyo.

5. Imiqathango

Ngaphambi kokwenza uvavanyo, kuyimfuneko ukuqonda imeko ethile yemathiriyeli yovavanyo kunye nemigangatho yovavanyo, kwaye ukhethe indlela efanelekileyo yovavanyo.

2. Iibholithi zezinto ezahlukeneyo kunye nezakhiwo, iamaxabiso omgangatho wovavanyozinokwahluka, kwaye amaxabiso omgangatho wovavanyo afanelekileyo kufuneka akhethwe ngokusekelwe kwiimeko ezithile.

Ngexesha lenkqubo yokuvavanya, kuyimfuneko ukulandela ngokuthe ngqo iinkqubo zokuvavanya ezifunekayo ukuqinisekisa ukuchaneka nokuthembeka kweziphumo zovavanyo.

Emva kokuba uvavanyo lugqityiwe, kuyimfuneko ukuhlalutya kunye nokuvavanya iziphumo zovavanyo, kunye nokucoca nokugcina izixhobo zokuvavanya kunye neebholithi.

【 Isiphelo 】

Uvavanyo lwe-decarburization ye-bolts ludlala indima ebalulekileyo kuvavanyo lomgangatho kunye nokuhlolwa kokhuseleko lwezixhobo, kwaye ixabiso lomgangatho wovavanyo yenye yeendlela ezibalulekileyo zokugweba ukusebenza kwezinto. Xa usenza uvavanyo lwe-decarburization kwiibholiti, kuyafuneka ukuba uqonde ngononophelo amaxabiso asemgangathweni ovavanyo, iindlela zovavanyo kunye nezilumkiso, kwaye ulandele ngokungqongqo inkqubo yovavanyo efunekayo ukuze uqinisekise ukuchaneka kunye nokuthembeka kweziphumo zovavanyo.

Njengokwenza iibholithi zeminyaka engama-20, ewe, sinomatshini onjalo wokuhlola ukuvavanya iimveliso zethu.
