iStainless Steel kunye noTyalo-mali lokuCasa

Phakathi kweenkqubo ezahlukeneyo zokuphosa, isinyithi esingenasici sichithwa ikakhulu ngokutyalwa kotyalo-mali okanyeinkqubo yokulahla i-wax elahlekileyo, kuba inokuchaneka okuphezulu kakhulu kwaye yiyo loo nto i-investment casting ikwabizwa ngokuba yi-precision casting.

Intsimbi estainless sisishunqulelo sentsimbi engenasici kunye ne-asidi-resistant. Ibizwa ngokuba yintsimbi engatyiwayo ekwaziyo ukumelana nezinto ezibuthathaka ezinjengomoya, umphunga namanzi. Intsimbi yokonakala ibizwa ngokuba yintsimbi enganyangekiyo kwiasidi.

Ngenxa yomahluko kukwakheka kweekhemikhali phakathi kwentsimbi eqhelekileyo engenastainless kunye nentsimbi enganyangekiyo ngeasidi, ukuxhathisa kwabo kokubola kwahlukile. Intsimbi yesiqhelo estainless ayixhathisi kwimichiza yemithombo yeendaba, ngelixa intsimbi enganyangekiyo ngeasidi ayidlali. Igama elithi "insimbi engenasici" alibhekiseli kuphela kuhlobo olulodwa lwensimbi engenasici, kodwa libhekisela kwiintsimbi ezingaphezu kwekhulu ze-industrial stainless. Intsimbi nganye engenasici ephuhlisiwe inokusebenza kakuhle kwintsimi yayo yesicelo esithile.

Intsimbi engatyiwayo ihlala yohlulwe ibe yintsimbi ye-martensitic, intsimbi engatyiwa yi-ferritic, intsimbi engatyiwa yi austenitic,i-austenitic-ferritic (i-duplex) insimbi engenasicikunye nemvula eyenza lukhuni intsimbi engatyiwayo ngokwemeko ye-microstructure. Ukongeza, ngokwemixholo yeekhemikhali, inokwahlulwa ibe yintsimbi ye-chromium, i-nickel ye-chromium yensimbi engenasici kunye ne-chromium manganese i-nitrogen yensimbi engenasici, njl.

Kwimveliso yokuphosa, ininzi yensimbi engenasici igqitywe ngokutyalo-mali. Umphezulu wensimbi engenasici eveliswa yi-investment casting ilula kwaye ukuchaneka kwe-dimensional kulula ukulawula. Kakade ke, iindleko zeutyalo-mali lokugalela iinxalenye zentsimbi engenasiciiphezulu kakhulu xa kuthelekiswa nezinye iinkqubo kunye nemathiriyeli.

Ukwenziwa kotyalo-mali, okukwabizwa ngokuba yi-precision casting okanye ukuphoswa kwewax elahlekileyo, isetyenziswa kakhulu njengoko ibonelela nge-asymmetrical casting eneenkcukacha ezihle kakhulu ukuba zenziwe ngexabiso eliphantsi. Inkqubo ibandakanya ukuvelisa intsimbi yesinyithi usebenzisa i-mold refractory eyenziwe kwi-wax replica pattern. Amanyathelo abandakanyekayo kwinkqubo okanye ukulahleka kwe-wax cast ngala:
• Yenza ipateni yewax okanye ikopi
• Hlikihla ipateni yewax
• Tyala ipateni yewax
• Susa ipateni yewax ngokuyitshisa (ngaphakathi kwiziko okanye emanzini ashushu) ukwenza isikhunta.
• Nyanzelisa ukugalela isinyithi esinyibilikisiweyo kumngundo
• Ukupholisa nokuqinisa
• Susa i-sprue kwi-castings
• Gqibezela kwaye upolishe utyalo-mali olugqityiweyo
