Izitini ze-alumina eziphakeme

Izinzuzo zomkhiqizo: ukuphindaphinda okuphezulu nokushisa kokunciphisa umthwalo, ngokwanda kokuqukethwe kwe-Al2O3, ukusebenza kwe-slag ukumelana kuthuthukiswa kakhulu.

Isicelo soMkhiqizo: Isetshenziselwa ikakhulukazi ulwelwesi lwamafutha wokuqhuma, iziko elishisayo lokushisa, izithando zomlilo kagesi, iziko lokuqhuma, iziko lokubuyisa, namakhoyili wokujikeleza. Ngaphezu kwalokho, izitini eziphakeme ze-alumina nazo zisetshenziswa kabanzi njengezitini ezihlola imigwaqo evulekile, amapulagi wokuthela izinhlelo, izitini zombhobho, njll.

incazelo yomkhiqizo

Ukufakwa kwezitini eziphakeme ze-alumina emlilweni ubuchwepheshe obubucayi kakhulu, ikakhulukazi ezindaweni ezinezakhiwo eziyinkimbinkimbi, izinguquko ezinkulu ekugobekeni nasezingxenyeni ze-arched ophahleni lwesithando somlilo. Ukufakwa kabi kwezitini eziphakeme ze-alumina kungaholela ekushiseni okuphezulu noma ngomlilo. Izitini ezijwayelekile zokuphikisa zizoletha ubunzima obukhulu ekwakhiweni. Ngakho-ke, kuyadingeka ukwenza ngezifiso izitini eziphakeme ezikhethekile ezimise okwe-alumina, ezinganciphisa ubunzima bokwakha nokuqeda izikhala ezingenzeka ngenxa yobunzima bokwakha lapho usebenzisa izitini ezisezingeni eliphakeme ze-alumina. Impilo yomlilo.

Ikhwalithi yokuma kwezitini ze-alumina eziphakeme ezikhethekile kufanele zihlangabezane nalezi zidingo ezilandelayo:

(1) Ukubekezelelana okukodwa: ukuphakama ukubekezelelana ± 2%; ubuso obunjenge-wedge obukhulu nokubekezelelana kwekhanda ububanzi ± 2mm; usayizi umehluko ukubekezelelana ± 1mm; ubude ukubekezelelana ± 1%. Izitini eziphakeme ezenziwe nge-alumina ezenziwe ngokwezifiso, umehluko ngu-2mm.

(2) Ukulahleka komphetho. Vumela uhlangothi olushisayo noma olubandayo ukuthi izinhlangothi ezimbili zilimale kuze kufike ku-40mm ubude no-5mm ukujula; kepha akuvunyelwe ukudlula.

(3) Ukulahleka kwe-Angular. Munye kuphela umonakalo ekhoneni owenziwe ngezifiso izitini eziphakeme ze-alumina ezindaweni ezishisayo nezibandayo, futhi ubude obuphelele bemiphetho emithathu yomonakalo wekhoneni akufanele bungeqi ku-50mm. Ukulahleka kwe-engela okungadluli u-20mm akubhekwa.

(4) Ukuqhekeka. Ubuso besitini buvunyelwe ukuthi bunemifantu emincane enjengezinwele; akukho imifantu ehambisana nendawo egqokiwe evunyelwe; eminye imifantu engekho ngaphezu kuka-40mm futhi ingabi banzi kuno-0.2mm ivunyelwe.

(5) Imigodi, amamaki ancibilikayo nama-bulges. Imigodi evumelekile namamaki ancibilikayo anobubanzi obungu-10mm nobubanzi obungu-10mm; i-bulge ingu-0.5mm. Izitini eziphakeme ze-alumina ezinemiphetho ehlukahlukene enenqwaba yezitini akumele zeqe ngama-70% esiphelele.
