Insimbi engagqwali isakazwa ngokuyinhloko ngokusakazwa kwe-wax elahlekile ngoba ingafinyelela endaweni ephakeme enembe nobukhulu.
Ukutshala imali nomaukukhishwa kwe-wax elahlekileiyindlela yokunemba kokuphonsa imininingwane eseduze yomumo we-net usebenzisa ukuphindaphinda kwamaphethini we-wax. Ukutshala imali noma i-wax elahlekile kuyinqubo yokwenza insimbi ngokuvamile esebenzisa iphethini ye-wax ezungezwe igobolondo le-ceramic ukwenza isikhunta se-ceramic. Lapho igobolondo loma, ingcina iyancibilika, kusale isikhunta kuphela. Khona-ke ingxenye yokuphonsa ikhiwa ngokuthululela insimbi encibilikisiwe esikhunjini se-ceramic.
Izinto ezisetshenziswa kakhulu zensimbi engagqwali ikakhulukazi zihlanganisa (kodwa azikhawulelwe): Insimbi Engagqwali: AISI 304, AISI 304L, AISI 316, AISI 316L, 1.4404, 1.4301 kanye nezinye izigaba zensimbi engagqwali.
Insimbi engagqwali inokuqukethwe kwe-chromium okungenani okungu-10.5%, okuyenza imelane kakhulu nezindawo zoketshezi ezibolayo kanye ne-oxidation. Iyakwazi ukumelana nokugqwala futhi imelana nokugqokwa, ihlinzeka ngokusebenza kahle kakhulu, futhi yaziwa kakhulu ngokubukeka kwayo kobuhle. Ukulingwa kwensimbi engagqwali "ayikwazi ukugqwala" uma kusetshenziswa ezindaweni eziwuketshezi nezihwamuko ezingaphansi kuka-1200°F (650°C) kanye "nokumelana nokushisa" uma kusetshenziswa ngaphezu kwaleli zinga lokushisa.
Izinto eziyisisekelo zealloy zanoma iyiphi isisekelo se-nickel-base noma insimbi engagqwali i-chromium, i-nickel, ne-molybdenum (noma "i-moly"). Lezi zingxenye ezintathu zizonquma ukwakheka okusanhlamvu kokulingisa kanye nezici zokuwumshini futhi zizoba wusizo ekhonweni lokusakaza lokulwa nokushisa, ukuguga, nokugqwala.
Eyethui-wax casting foundry elahlekileingakhiqiza isikoinsimbi engagqwali utshalomali castingsehambisana ncamashi nencazelo yedizayini yakho. Ezingxenyeni ezisukela kumashumi amagremu kuya kumashumi amakhilogremu noma ngaphezulu, sinikeza ukubekezelelana okuqinile kanye nengxenye engaguquki ukuya kokuphindaphindeka kwengxenye.
Ngokujwayelekile, insimbi engagqwali kufanele iphonswe yinqubo yokufaka ngokunemba kokutshala imali nge-silica sol njengebhondi. I-stainless steel silica sol castings inebanga eliphezulu kakhulu lokunemba kwendawo nokusebenza.
Ngenxa yezakhiwo zayo ezibonakalayo eziyingqayizivele, ukulingwa kwensimbi engagqwali kudumile ezinhlobonhlobo zezinhlelo zokusebenza, ikakhulukazi lezo ezisezindaweni ezinokhahlo. Izimakethe ezivamile zokutshala izimali zensimbi engagqwali zihlanganisa uwoyela negesi, amandla oketshezi, ezokuthutha, amasistimu asebenza ngamanzi, imboni yokudla, ihadiwe kanye nezingidi, ezolimo...njll.
Inqubo ifanele ukukhiqizwa okuphindaphindekayo kwezingxenye zomumo wenetha kusuka ezinhlobonhlobo zezinsimbi ezihlukene kanye nama-alloys asebenza kahle. Nakuba ngokuvamile isetshenziselwa ukulingisa okuncane, le nqubo isetshenziselwe ukukhiqiza amafreyimu eminyango yendiza ephelele, enensimbi efika ku-500 kgs kanye nokusakazwa kwe-aluminium kufika ku-50 kgs. Uma kuqhathaniswa nezinye izinqubo zokulingisa ezifana ne-die casting noma ukwenza isihlabathi, kungaba inqubo ebizayo. Kodwa-ke, izakhi ezingakhiqizwa kusetshenziswa ukufakwa kwe-investimenti zingahlanganisa amakhonsathi ayinkimbinkimbi, futhi ezimeni eziningi izingxenye ziphonswa eduze komumo wengqikithi, ngakho-ke zidinga ukusetshenzwa kabusha okuncane noma zingasasebenzi lapho kwasakazwa.
Inqubo ye-silica sol casting iyinqubo eyinhloko yokutshala imali yensimbi ye-RMC yokufaka isisekelo sokutshala imali. Besilokhu sakha ubuchwepheshe obusha bezinto zokunamathela ukuze sifinyelele izinto zokunamathela ezinokonga kakhulu futhi ezisebenzayo ukuze kwakhiwe igobolondo le-slurry. Kuwumkhuba omangalisayo ukuthi inqubo ye-Silica sol casting ingena esikhundleni senqubo yengilazi yamanzi esezingeni eliphansi, ikakhulukazi yokusakazwa kwensimbi engagqwali kanye nokusakazwa kwensimbi yengxubevange. Ngaphandle kwempahla yokubumba esunguliwe, inqubo ye-silica sol casting nayo iye yasungulwa ukuze izinze futhi ikhulise ukushisa okuncane.
