(1) Imifantu iyisici esivame kakhulu samabhodlela engilazi. Imifantu mihle kakhulu, kanti eminye ingatholakala kuphela ekukhanyeni okuveziwe. Izingxenye lapho zivame ukwenzeka khona umlomo webhodlela, ibhodlela nehlombe, kanti umzimba webhodlela kanye naphansi kuvame ukuba neminkenke.
(2) Ubukhulu obungalingani Lokhu kubhekisela ekusabalaleni okungalingani kwengilazi ebhodleleni lengilazi. Ngokuyinhloko kungenxa yokushisa okungalingani kwamaconsi engilazi. Ingxenye yokushisa ephezulu ine-viscosity ephansi, futhi ukucindezela okushayayo akwanele, okulula ukushaya okuncane, okuholela ekusabalaliseni kwezinto ezingalingani; ingxenye yokushisa ephansi inokumelana okuphezulu futhi ishubile. Izinga lokushisa lesikhunta alilingani. Ingilazi ohlangothini lwezinga lokushisa eliphezulu ipholisa kancane futhi kulula ukuyiphephetha ibe izacile. Uhlangothi lwezinga lokushisa eliphansi lushaywa umoya ngoba ingilazi ipholisa ngokushesha.
(3) Ukuguquguquka Izinga lokushisa lamaconsi kanye nezinga lokushisa lokusebenza kuphezulu kakhulu. Ibhodlela elikhishiwe esikhunjeni esakhayo alikakakhiwa ngokugcwele futhi livame ukugoqa futhi libe nokukhubazeka. Ngezinye izikhathi ibhodlela eliphansi lisathambile futhi lizonyatheliswa ngemikhondo yebhande lokuhambisa, okwenza ibhodlela lingalingani.
(4) Izinga lokushisa lamaconsi elingaphelele liphansi kakhulu noma isikhunta sibanda kakhulu, okuzokwenza ukuthi umlomo, ihlombe nezinye izingxenye zishaywe umoya zingaphelele, okubangela izikhala, ukucwila kwamahlombe namaphethini angacacile.
(5) Izindawo ezibandayo Iziqephu ezingalingani endaweni yengilazi zibizwa ngokuthi izindawo ezibandayo. Isizathu esiyinhloko salesi sici ukuthi izinga lokushisa lomodeli libanda kakhulu, elivame ukwenzeka lapho uqala ukukhiqiza noma umisa umshini wokukhiqiza kabusha.
(6) Ama-protrusions Ukonakala komugqa womthungo webhodlela lengilazi ophumela ngaphandle noma unqenqema lomlomo ophumela ngaphandle. Lokhu kubangelwa ukwenziwa okungalungile kwezingxenye zemodeli noma ukufakwa okungafanele. Uma imodeli yonakalisiwe, kukhona ukungcola ebusweni bomthungo, umgogodla ophezulu uphakanyiswa sekwephuzile kakhulu futhi impahla yengilazi iwela ekubunjweni okuyinhloko ngaphambi kokungena endaweni, ingxenye yengilazi izocindezelwa ngaphandle noma ikhishwe ngaphandle kwegebe.
(7) Imibimbi inokuma okuhlukahlukene, eminye igoqekile, kanti eminye imibimbi emihle kakhulu emashidini. Izizathu eziyinhloko zemibimbi ukuthi i-droplet ibanda kakhulu, i-droplet yinde kakhulu, futhi i-droplet ayiwi phakathi kwesikhunta esiyinhloko kodwa ibambelela odongeni lwe-mold cavity.
(8) Ukonakala kwendawo Ubuso bebhodlela bumahhadlahhadla futhi alilingani, ikakhulukazi ngenxa yamaholoholo omgodi wokukhunta. Amafutha okugcoba angcolile kusikhunta noma ibhulashi elingcolile azophinde anciphise izinga eliphezulu lebhodlela.
9
(10) Amamaki esikele Imikhondo esobala esele ebhodleleni ngenxa yokugunda kabi. Iconsi lempahla livamise ukuba namamaki esikere amabili. Uphawu lwesikelo olungaphezulu lushiywe ngezansi, luthinta ukubukeka. Uphawu lwesikelo olungezansi lushiywa emlonyeni webhodlela, okuvame ukuba wumthombo wokuqhekeka.
(11) Ama-Infusibles: Izinto ezingezona ingilazi eziqukethwe engilazini zibizwa ngokuthi ama-infusibles.
1. Isibonelo, i-silica engancibilikisiwe iguqulwa ibe i-silica emhlophe ngemva kokudlula ku-clarifier.
2. Izitini eziphikisayo ku-batch noma i-cullet, njenge-fireclay nezitini eziphakeme ze-Al2O3.
3. Izinto zokusetshenziswa ziqukethe ukungcola okungasuleki, okufana ne-FeCr2O4.
4. Izinto eziphikisayo esithandweni somlilo ngesikhathi sokuncibilika, njengokucwecwa nokuguguleka.
5. I-Devitrification yengilazi.
6. Ukuguguleka nokuwa kwezitini ezenziwe ngogesi ze-AZS.
(12) Izintambo: Ukungahlangani kwengilazi.
1. Indawo efanayo, kodwa enomehluko omkhulu wokwakheka, ibangela izimbambo ekubunjweni kwengilazi.
2. Akukhona nje kuphela ukuthi izinga lokushisa alilingani; ingilazi ipholiswa ngokushesha futhi ngokungalingani ekushiseni okusebenzayo, ukuxuba ingilazi eshisayo nebandayo, ethinta indawo yokukhiqiza.
