Ungawakha Kanjani Amathuluzi Okusika I-Tungsten Carbide

I-brazing yamathuluzi okusika i-carbide enosimende ithinta ikhwalithi yethuluzi. Ngaphezu kokuthi isakhiwo samathuluzi silungile futhi ukukhethwa kwezinto zamathuluzi kufanelekile, esinye isici esibalulekile sincike ekulawuleni izinga lokushisa lokushisa.

Ngesikhathi sokukhiqiza, kunezindlela eziningi zokubhula zamathuluzi okusika i-tungsten carbide, nezici zabo ze-brazing nezinqubo nazo zihlukile. Izinga lokushisa linomthelela obalulekile kwikhwalithi yokubhula. Ukushisa okusheshayo kungabangela ukuqhekeka kanye ne-braze engalingani ekufakweni kwe-carbide. Kodwa-ke, uma ukushisa kuhamba kancane, kuzodala i-oxidation ye-welding surface, okuholela ekwehleni kwamandla okubhula.

Lapho brazing amathuluzi okusika i-carbide, ukushisa okufanayo kwe-shank yamathuluzi kanye nethiphu ye-carbide kungenye yezimo eziyisisekelo zokuqinisekisa ikhwalithi yokubhoboza. Uma izinga lokushisa lokushisa kwephuzu le-carbide liphakeme kune-shank, i-solder encibilikile imanzisa i-carbide kodwa hhayi i-shank. Kulokhu, amandla okubhula ayancipha. Lapho ithiphu le-carbide ligundwa eceleni kwesendlalelo se-solder, i-solder ayilimazi kodwa ihlukaniswa nethiphu ye-carbide. Uma isivinini sokushisisa sishesha kakhulu futhi izinga lokushisa lebha yamathuluzi liphakeme kunethiphu ye-carbide, into ephambene izokwenzeka. Uma ukushisa kungenakufaniswa, ezinye izingxenye ziboshwe kahle, kanti ezinye izingxenye azigxiliwe, okunciphisa amandla okubamba. Ngakho-ke, ngemva kokufinyelela ekushiseni kwe-brazing, ngokusho kobukhulu bethiphu ye-carbide, kufanele igcinwe imizuzwana engu-10 kuya kwezingu-30 ukwenza izinga lokushisa endaweni yokushisa iyunifomu.

Ngemuva kokubhula, izinga lokupholisa lethuluzi libuye libe nobudlelwano obuhle nekhwalithi yokubhula. Lapho ukupholisa, ukucindezeleka okuqinile okusheshayo kukhiqizwa phezu kwethiphu ye-carbide, futhi ukumelana kwe-tungsten carbide ekucindezelekeni okuqinile kubi kakhulu kunokucindezeleka okucindezelayo.

Ngemuva kokuthi ithuluzi le-tungsten carbide liboshwe, ligcinwa lifudumele, lipholile, futhi lihlanzwa nge-sandblasting, bese uhlola ukuthi i-carbide efakwe ifakwe ngokuqinile kumphathi wamathuluzi, noma ngabe kukhona ukuntuleka kwethusi, isiphi isikhundla se-carbide. faka ku-slot, nokuthi i-carbide insert inemifantu.

Hlola ikhwalithi ye-braze ngemva kokulola ingemuva lethuluzi ngesondo le-silicon carbide. Engxenyeni yethiphu ye-carbide, i-solder enganele kanye nokuqhekeka akuvunyelwe.

Kusendlalelo sokubhula, igebe elingagcwalisiwe nge-solder akufanele libe likhulu kune-10% yobude obuphelele be-braze, ngaphandle kwalokho, kufanele lidayiswe kabusha. Ubukhulu bengqimba ye-welding akufanele budlule u-0.15 mm.

Hlola ukuthi indawo yokufaka i-carbide endaweni yokufaka i-welding iyahlangabezana yini nezidingo zobuchwepheshe.

Ukuhlola amandla okubrawuza ukusebenzisa into yensimbi ukushaya ibha yamathuluzi ngokuqinile. Lapho ushaya, i-blade akufanele iwe kubha yamathuluzi.

Ukuhlolwa kwekhwalithi ye-Carbide yokusika ikhwalithi ukuqinisekisa impilo yesevisi ye-carbide blade, futhi kuyisidingo sokusebenza okuphephile.

Uma uthanda amathuluzi okusika i-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-MEyili ezansi ekhasini.
