Yiziphi izidingo ze- impahla ye-lining yodonga lwesithando somlilo we-induction?

1. I-refractoriness eyanele

Izinto ezine-refractoriness ephakeme kuno-1580°C zibizwa nge-refractory materials. Izinga lokushisa lokusebenza kolwelwesi lwesithando somlilo ngokuvamile liphansi kunezinga lokushisa lensimbi encibilikisiwe. Kodwa-ke, ngokuya ngezidingo zempilo yolayini lwesithando somlilo, izinga lokushisa elenziwe ngengozi noma elivamile lechibi elincibilikisiwe kanye nechibi elincibilikisiwe kufanele kubhekwe. I-refractoriness esetshenziswa esithandweni sokungeniswa kwe-iron kanye nezinto ezinezinga lokushisa eliphansi lokuthambisa ngokuvamile aziphephile. Njengeshaja yesithando somlilo sikagesi yesithando somlilo esisansimbi,

I-refractoriness yayo kufanele ibe ngu-1650 ~ 1700 ℃, futhi izinga lokushisa layo elithambile kufanele libe ngaphezu kuka-1650 ℃.

2. Ukuzinza okuhle kokushisa

Isithando somlilo sokungeniswa sincike ekwenziweni kwe-electromagnetic ukushintshanisa amandla. Ukuze kuqinisekiswe ukuthi isithando somlilo sisebenza kahle kakhulu kagesi, lokhu kwenza ulayini lwesithando somlilo lusebenze nge-gradient enkulu ye-radial lokushisa. Ngaphezu kwalokho, izinga lokushisa lomlilo wesithando somlilo lihlala lishintsha ngenxa yethonya lokushaja, ukuthepha, nokuvalwa kwesithando somlilo ngesikhathi sokusebenza kwesithando somlilo, futhi uhlaka lwesithando somlilo luvame ukuqhekeka ngenxa yokushisa okungalingani, okunciphisa impilo yesevisi. yolwelwesi lwesithando somlilo. Ngakho-ke, njenge-refractory yezithando zikagesi, kufanele ibe nokuzinza okuhle kakhulu kokushisa.

3. Ukuzinza okuhle kwamakhemikhali

Ukuzinza kwamakhemikhali wezinto ezibonakalayo kuhlobene eduze nempilo yomugqa wesithando somlilo. Impahla ye-lining akufanele ifakwe i-hydrolyzed futhi ihlukaniswe emazingeni okushisa aphansi, futhi akufanele ibole kalula futhi yehliswe emazingeni okushisa aphezulu. Akufanele kube lula ukwenza izinto ezincibilika kancane nge-slag ngesikhathi senqubo yokuncibilika, futhi akufanele isabele ngamakhemikhali ngezixazululo zensimbi nezithasiselo, futhi ngeke zingcolise izixazululo zensimbi.

4. I-coefficient encane yokwandisa ukushisa

Ivolumu kufanele izinze ngokuqhathaniswa nokushintsha kwezinga lokushisa, ngaphandle kokukhula okusheshayo nokuncipha.

5. Inezakhiwo ezisezingeni eliphezulu,

Kumelwe ikwazi ukumelana nokukhishwa kwenkokhelo yangaphakathi lapho insimbi isesimweni sokushisa esiphansi; lapho insimbi isesimweni sokuncibilika kwezinga lokushisa eliphezulu, kufanele ikwazi ukumelana nokucindezela okumile kwensimbi encibilikisiwe kanye nomthelela onamandla kagesi onyakazayo; ukumelana nokugqoka kanye nokumelana nokugqwala ngaphansi kokuguguleka kwesikhathi eside kwensimbi encibilikisiwe.

6. I-insulation enhle

Ilayini yesithando somlilo akufanele iqhube ugesi ngaphansi kwezimo zokushisa eziphezulu, ngaphandle kwalokho izobangela ukuvuza kanye namasekethe esikhashana, okuholela ezingozini ezimbi.

7. Ukusebenza kokwakhiwa kwempahla kuhle, kulula ukulungisa, okungukuthi, ukusebenza kwe-sintering kungcono, futhi ukwakhiwa nokugcinwa kwesithando somlilo kulula.

8. Izinsiza eziningi namanani aphansi.

Akunzima ukubona ukuthi izidingo zezinto eziphikisayo zezithando zokungeniswa ziqinile, futhi cishe akukho mpahla yemvelo ephikisayo engahlangabezana nalezi zidingo ezingenhla. Lokhu kudinga ukukhethwa kwezinto ezifanele zokuphikisa ngokuvumelana nezimo ezihlukahlukene zokusetshenziswa. Ngesikhathi esifanayo, imithombo yamaminerali yemvelo kufanele ihlanzwe, ihlanganiswe futhi iphinde icutshungulwe ukuze yenze ukusebenza kwayo kuhlangabezane nezidingo zomlilo wokungeniswa.
