Insimbi Engagqwali ikakhulu isakaza ngokulahleka kwe-wax ekubunjweni ngoba ingafinyelela endaweni ephezulu nenembile.
Ukutshalwa kwezimali noma ukulahlwa kwe-waxkuyindlela yokucacisa ukusakaza imininingwane eyinkimbinkimbi eseduze-net-shape kusetshenziswa ukuphindaphindeka kwamaphethini we-wax. Ukutshalwa kwezimali noma i-wax elahlekile kuyinqubo yokwakha insimbi esebenzisa iphethini ye-wax ezungezwe yigobolondo le-ceramic ukwenza isikhunta sobumba. Lapho igobolondo loma, i-wax iyancibilika, kushiye isikhunta kuphela. Lapho-ke isakhi sokusakaza sakhiwa ngokuthela insimbi encibilikisiwe kusikhunta sobumba.
Izinto ezisetshenziswa kakhulu zensimbi engagqwali zifaka phakathi (kepha azikhawulelwanga): Insimbi Engagqwali: I-AISI 304, i-AISI 304L, i-AISI 316, i-AISI 316L, i-1.4404, i-1.4301 kanye nezinye ibanga lensimbi engagqwali.
Insimbi engenalutho inokuqukethwe okuncane kwe-chromium okungu-10.5%, okwenza ikwazi ukumelana kakhulu nezindawo zoketshezi ezonakalisayo kanye ne-oxidation. Kuyinto ukumelana ukugqwala kakhulu futhi ukugqoka nemithi, inikeza machinability omuhle, futhi waziwa kahle ukubukeka kwalo yobuhle. Ukufakwa kwezinsimbi ezingenasici "kungamelana nokugqwala" uma kusetshenziswa ezindaweni eziwuketshezi nemiphunga engaphansi kwe-1200 ° F (650 ° C) kanye "nokungamelana nokushisa" uma kusetshenziswe ngaphezu kwaleli zinga lokushisa.
Izingxenye ze-base alloy zanoma yikuphi ukusakazwa kokutshalwa kwemali kwe-nickel-base noma insimbi engagqwali yi-chromium, i-nickel, ne-molybdenum (noma i- "moly"). Lezi zingxenye ezintathu zizonquma ukwakheka kokusanhlamvu nokwakhiwa kwemishini futhi kuzoba usizo kakhulu ekubunjweni kokushisa, ukugqoka nokugqwala.
Okwethu ilahlekile i-wax ekubunjweni kwesisekelo ingaveza isiko elingenasici insimbi yokutshala imaliehambelana nemininingwane yakho ngqo yokuklama. Ezingxenyeni ezisukela emashumini amagremu kuya kumashumi amakhilogremu noma ngaphezulu, sinikeza ukubekezelelana okuqinile nengxenye engaguquguquki ekuphindaphindweni kwengxenye.
Imvamisa, insimbi engagqwali kufanele iphonswe ngenqubo yokukhipha imali ngokunemba nge-silica sol njengesibopho. I-castings ye-silica sol castings inebanga eliphakeme kakhulu lobuso nokusebenza ngokunembile.
Ngenxa yezakhiwo zayo ezihlukile zomzimba, ukusakazwa kwensimbi engagqwali kuyathandwa ezinhlotsheni eziningi zezicelo, ikakhulukazi lezo ezisendaweni enokhahlo. Izimakethe ezijwayelekile zokuphonsa insimbi engagqwali zifaka uwoyela negesi, amandla kagesi, ezokuhamba, amasistimu wokubacindezela, imboni yokudla, ihadiwe kanye nezikhiye, ezolimo ... njll.
Le nqubo ilungele ukukhiqizwa okuphindaphindwayo kwezakhi zomumo wenetha kusuka kuzinsimbi ezahlukahlukene ezahlukahlukene nama-alloys wokusebenza okuphezulu. Yize ijwayele ukusetshenziselwa ukusakaza okuncane, le nqubo isetshenziselwe ukukhiqiza amafreyimu eminyango yendiza ephelele, enezinsimbi ezifinyelela kuma-500 kgs kanye ne-aluminium castings efinyelela kuma-50 kgs. Uma kuqhathaniswa nezinye izinqubo ekubunjweni ezifana die ekubunjweni noma isihlabathi thusi, kungaba inqubo ebizayo. Kodwa-ke, izinto ezingakhiqizwa kusetshenziswa ukusatshalaliswa kotshalo-mali zingafaka imigwaqo eyinkimbinkimbi, futhi ezimweni eziningi izingxenye ziphonswa eduze kwesimo senetha, ngakho-ke zidinga ukuvuselelwa okuncane noma ukungaphindi kwenziwe uma sekuphonsiwe.
Silica sol ekubunjweni inqubo main steel utshalomali thusi inqubo RMC utshalomali thusi Foundry. Besilokhu sithuthukisa ubuchwepheshe obusha bezinto zokunamathisela ukuze kuzuzwe okokunamathela nokonga okuthe xaxa kokwakha igobolondo le-slurry. Kungumkhuba okhandlayo ukuthi inqubo ye-Silica sol casting ingena esikhundleni senqubo yengilazi yamanzi engezansi, ikakhulukazi ekubunjweni kwensimbi engagqwali kanye nasekukhipheni i-alloy steel. Ngaphandle kwezinto ezisunguliwe zokubumba, inqubo yokulingisa i-silica sol nayo isungulwe ukuze ikhule kakhulu futhi kunciphe ukushisa okuncane.
