Ukwelashwa okushisa ngokweqile kuhlukaniswe izigaba ezimbili: enye ingabe ukwelashwa okushisa ngokweqile nokufudumele, kanti okunye ukwelashwa okushisa kwamakhemikhali. Indlela yokuhlola kanzima imi ngalendlela elandelayo:
1. Ukwelashwa okushisa ngokweqile nomoya ovuthayo
Ukwelashwa okushisa ngokweqile nokufudumala kuvame ukwenziwa ngokufudumeza ukufudumeza noma ukufudumeza kwelangabi. Amapharamitha aphambili obuchwepheshe ubulukhuni obukhulu, ubulukhuni bendawo kanye nokujula kwesendlalelo okuqinile okuvuthiwe. I-Vickers Hardness Tester noma umhloli wobulukhuni we-Rocwell angasetshenziselwa ukuhlolwa kanzima. Ukuhlola amandla okukhethwa kukho okukhethiwe kuhlobene nokujula kwesendlalelo esivuthayo esithuthukile kanye nobulukhuni obukhulu bokusebenza. Kunemishini emithathu yobulukhuni ebandakanyeka lapha.
. Ingasebenzisa amandla okuhlola angu-0.5-100kg ukuvivinya ungqimba oluqinile olukhuni njengelungu elincanyana njenge-0.05mm ubukhulu. Ukunemba kwaso kuphakeme futhi kungahlukanisa izisebenzi eziphathwa ukushisa. Umehluko omncane ngobulukhuni obukhulu, ngaphezu kwalokho, ukujula kwesendlalelo esivuthayo esisebenzayo kutholakala nomhloli we-hardness we-vickers, ngakho-ke kuyadingeka ukuhlomisa ubuqili be-vickers Hardener for aunits noma basebenzise inani elikhulu le-superfreative ukwelashwa kokwelashwa.
. Kunezikali ezintathu ze-Superfac Rocwell Hurneness Tester ongakhetha kuzo. Ingavivinya ama-Workplether ahlukahlukene aqinile aqine aqine aqine avuthiwe ngo-0.1mm. Yize ukunemba kwe-SuperFoull Harvell Testness Aspere akuphezulu kwaleyo enobuqili be-Heater Harvener, kungenzeka ukuthi bahlangabezana nezidingo njengendlela yokutholwa yokuphathwa kwekhwalithi kanye nokuhlolwa kweziqu kweziqu zokuhlola ukushisa izitshalo. .Besusides, futhi inezici zokusebenza okulula, ukusetshenziswa okulula, intengo ephansi, ukukalwa okusheshayo, nokufundwa okuqondile kwamanani elukhuni. Umhloli wobulukhuni obunamandla amakhulu angasetshenziswa ukushesha futhi angekheki abone ama-batches we-superfacted arpieges arpieces ngamunye ngamunye. Kubaluleke kakhulu ekusebenzeni kwensimbi kanye nemishini yokukhiqiza imishini. Lapho ukwelashwa okushisa ngokweqile kwesendlalelo lukhuni, i-Rocwell Hardeness tester nayo ingasetshenziswa. Lapho ukushuba kwe-Heat Treatner Hardness Hardness upredness kungu-0.4-0.8mm, isikali se-HRA singasetshenziswa. Lapho ukujula kwesendlalelo oluqinile lapho kudlula u-0.8mm, isilinganiselo sakwa-HRC singasetshenziswa. Ama-Vickers, ama-rocwell kanye ne-superficial Rocwell Amanani Asezingeni elijwayelekile kathathu angaguqulwa kalula, aguqulwe abe ngamazinga, imidwebo noma amanani alukhuni noma itafula lokuguqula elihambisanayo liku-International Standard ISO. I-American Standard ASTM kanye ne-Chinese ejwayelekile ye-GB / T inikezwe.
. Lapho ukukala, ukunakwa kufanele kukhokhwe endaweni ethile engekho emthethweni kanye nobukhulu obujwayelekile bokusebenza. Le ndlela yokulinganisa ayinawo amaVickers ne-Rocwell Inhloli ye-Hardness inembile, kepha ilungele ukukalwa esizeni efektri.
2 Ukwelashwa okushisa kwamakhemikhali
Ukwelashwa okushisa kwamakhemikhali ukungenelela okungaphezulu kokusebenza kwe-workfice nge-athomu yezakhi eyodwa noma eziningi zamakhemikhali, ngaleyo ndlela kushintsha ukwakheka kwamakhemikhali, ukwakheka kanye nokusebenza kwe-superficial of the workpiepe. Ngemuva kokucimana nokushisa okuphansi okuphansi, okungaphezulu kokusebenza kwendawo yokusebenza kunobulukhuni obuphezulu nokugqoka ukumelana. Futhi thintana nokukhathala, futhi umnyombo wesisebenzi sokusebenza unamandla aphezulu nokuqina. Amapharamitha asemqoka wobuchwepheshe bokushisa kokushisa kwamakhemikhali ukujula kwesendlalelo esilukhuni nobulukhuni obukhulu. Ibanga lapho ubulukhuni behla ku-50hrc luwukujula kwesendlalelo okuthuthukile okuthuthukile. Ukuhlolwa kobulukhuni obukhulu bokushisa okushisayo kwamakhemikhali kufana nokuhlolwa kobulukhuni be-superfled ashited Heat Heat Heatpred Workies. Abahloli bakaHardness Burners, abahloli buka-Burfness abasezingeni eliphakeme noma abahloli buka-Rocwell bangasetshenziswa. Umhloli we-Harveness ukuthola, ukushuba kuphela kwe-nitring mnene nje, ngokuvamile kungabi ngaphezu kwe-0.7mm, khona-ke umhloli wobulukhuni be-Rocwell akakwazi ukusetshenziswa
3. Ukwelashwa kokushisa kwasendaweni
Uma izingxenye zokushisa zokushisa zasendaweni zidinga ubulukhuni obuphakeme bendawo, ukwelashwa okushisa kwasendaweni kungenziwa ngokufudumeza kwe-induction, njll. Inani lezingxenye zendawo ngokuqothula, ithuluzi lokuhlola kanzima lingasebenzisa umhloli wobulukhuni be-HRC ukuvivinya ubulukhuni be-HRC. Uma ukwelashwa okushisa lukhuni ungqimba lukhuni lujulile, umhloli wobulukhuni obunamandla amakhulu angasetshenziswa ukuvivinya inani le-HRN hardness value
