Ukwelashwa ukushisa ensimbi - obalulekile metal inqubo ukukhiqizwa

ukwelashwa ukushisa ensimbi - kuba ebalulekile yensimbi ingxubevange yokukhiqiza inqubo, esiza ukuthuthukisa izakhiwo wabo ozuzisayo. Namuhla, le nqubo isetshenziselwa ukuguqula izici zemvelo imikhiqizo kakhulu metal.

ukwelashwa ukushisa ka lezinsimbi kuhilela ukuqaliswa esingaguquguquki izigaba ezintathu:

1. Amalahle ingxubevange yensimbi lokushisa oyifunayo.
2. Exposure babe ngokuhamba kwesikhathi.
3. Cooling.

Kwenzakalani ingxubevange yensimbi nge inqubo enjalo?

ukwelashwa ukushisa siqukethe izinyathelo ezilandelayo:

1. Annealing. Le nqubo ibizwa ikakhulukazi esetshenziselwa Reflux, kweqa futhi ekwakheni. Le nqubo kuyadingeka ukunciphisa ubulukhuni noma ukunciphisa ukucindezeleka okungajwayelekile yangaphakathi zidalwe e umkhiqizo eziphothene. Ngaphezu kwalokho, annealing isetshenziselwa ukulungiswa isakhiwo sensimbi ezishisayo post-ukwelashwa imvelo ukuze sithuthukise heterogeneity yayo. Kule ndlela kuhlanganisiwe ukushisa ekwelapheni steel 45, 45H, 40XC, 40XH nezinye izimpawu yensimbi ingxubevange.

2. Kokulinganisa. Le nqubo ihlukile inqubo yangaphambilini, ubunjalo ukudlula esigabeni lwaluyophola. Isinyathelo sokugcina Kwenziwa emva ubambe izingxenye. Ngokukhethekile ikhokhelwa lokushisa kusengaphambili. Kulesi simo steel etholwe nge ubulukhuni ongaphakeme kodwa ephakeme. Isakhiwo mikhiqizo okuncane. Ngakho, ukuzinza sasidingeka ukulungisa indlela yokwakheka le weld, futhi ukuthola ukucushwa oyifunayo.

3. ukuqina. Lesi sinyathelo elihlobene ne ukucutshungulwa steel, isetshenziswa Forgings, Castings, stampings, kanye nemininingwane iphathwa athutha ukuze andise amandla, ubulukhuni, ukugqwala ukumelana, ukugqoka ukumelana, kanye nezinye izici ezibalulekile. Lokhu kuhilela amalahle ingxubevange yensimbi lokushisa ngenhla noma ngaphakathi ushintsho yayo efanayo. Khiphela nge enjalo steel termopokazatele kanye nokupholisa okwalandela Kwenziwa ngokuvamile ngesivinini ethe xaxa. Ngenxa yale njongo kuvame kakhulu ukuba kusetshenziswe NaOH aqueous usawoti izixazululo, amafutha, kanye emoyeni. Ngakho, ngokwesibonelo, ukwelashwa ukushisa of okuhlinza 40X kulesigaba wenziwa uwoyela. Izimo zethu zihluke kakhulu ezingavamile usayizi enkulu izingxenye lukhuni emanzini kulandela ngokushesha nge ukukhululwa ongaphakeme. Ngokuvamile imikhiqizo yalesi brand yensimbi ingxubevange ukudlula lesi sinyathelo ngokubeka amalahle imisinga ephezulu imvamisa. Imiphumela iba yinhlanganisela yokukhandleka ebusweni okusezingeni eliphezulu okuqinile.

4. Shiya. Le nqubo liqukethe Ukushisa steel lukhuni lokushisa ethile. Okulandelayo, ukuchayeka metal sihamba, kanye nokupholisa. Isinyathelo sokugcina Kwenziwa ngokuvamile emoyeni.

5. Ukuguga. Lesi sinyathelo iqukethe ekugcineni yensimbi ingxubevange nge isakhiwo metastable isikhathi eside. Temperature akufanele kube ngezansi ekamelweni lokushisa. Le nqubo ivumela isakhiwo metal kancane ukuhambisa kusimo uzinze ngokushintsha izindawo zabo mechanical ngokomzimba.

6. ukuphathwa Cold. Lesi sinyathelo iwukuqhutshwa Ningamcimi Ukupholisa, yalengiswa at Igumbi lokushisa. Inkomba ye-metal akuyona ezingeni esibucayi.

Izicelo yensimbi ingxubevange

Njengoba steel ukushisa ekwelapheni inqubo kungaba ngokuphawulekayo ngcono izici izingxenye ezenziwe kusukela ingxubevange yensimbi lemikhiqizo ezahlukene, kuba bayindlala kakhulu kuzo zonke izindawo mboni. Iyathinteka kakhulu nekhono lokushintsha izakhi, ukwakhiwa izindiza, ithangi wokwakha, ukukhiqizwa kwemikhiqizo ngokhonkolo. Imikhiqizo, ukushisa kabi, ingasetshenziswa ngaphansi anda umthwalo ashukumisayo vibration. Ngaphezu kwalokho, yensimbi Alloys asetshenziswa ekwakhiweni namabhilidi, izimboni kanye namabhuloho.
