Yiziphi izinto zokwenziwa ezisetshenziswayo ezisetshenziswa ezithandweni ze-aluminium zezimboni?

Izinto zokuphikisa zamakhemikhali ezimboni ze-aluminium ngokuvamile ziyizitini ezinenkani kanye nokukhishwa, kepha ukukhetha kuyehluka kakhulu ngokuya ngezingxenye ezahlukahlukene. Izinkomba zamakhishi ezimboni ze-aluminium zidinga ukuba namandla amakhulu okusika, ubukhulu bepore encane, okuqukethwe okuphansi kwe-SiO2, Na2O, ne-K2O. Ulwelwesi lwesithando somlilo kufanele futhi lube nokusebenza kahle kokuhlwaya kokushisa ku-800 ° C. Umhleli we-Kerui Refractories uqoqe izinto ezijwayelekile zokuphikisa ezithandweni ze-aluminium zezimboni ukuze ubhekisele kuzo kuphela.

Isendlalelo sokufudumeza somlilo we-alumina rotary simbozwe ungqimba lwefayibha elikhanyayo elizwakala kugobolondo lomlilo, bese lakhiwa ngomhlaba o-diatomaceous, izitini zobuhlalu ezintantayo noma izitini zobumba ezikhanyayo, kanti ezinye zazo manje sezithathelwa indawo ngamakhandlela akhanyayo akhanyayo. Ulwelwesi olusebenzayo lwendawo yokufudumeza indawo lakhiwe ngezitini zobumba, futhi izitini eziphakeme ze-alumina noma izitini eziphakeme ze-alumina zisetshenziselwa indawo yokubala ephezulu.

Njengamanje, ama-Refractories angashintshiwe asetshenziswe kabanzi embonini ye-aluminium, njenge-castine ephansi ye-calcium aluminate-ehlanganisiwe ekhonjiwe endaweni yokubala, kanye nensimbi yensimbi eqinisa ukugqokwa okungamelana nemilomo yomlilo, imaskhi yomlilo, nemisila yomlilo.

Isithando somlilo kufakwa izipikili zehange lensimbi ezingamelana nokushisa noma amahange e-ceramic kugobolondo lesithando somlilo, bese sisabalalisa ungqimba lwamafreyimu angama-20mm awugqinsi, futhi ekugcineni uthele ama-castable angama-200-300 aminyene.

Ulwelwesi olusebenzayo lwesithando esiphindaphindayo sesithando sokuncibilikisa i-aluminium lapho sihlangana ne-aluminium encibilikisiwe ngokuvamile sakhiwe ngezitini eziphakeme ze-alumina ngokuqukethwe kwe-Al2O3 okungu-80-85%; lapho kuncibilikiswa insimbi ephezulu ye-aluminium, kusetshenziswa izitini ze-mullite noma izitini ze-corundum. Emthambekeni weziko, faka imfucumfucu i-aluminium nezinye izingxenye ezifuthwe kalula nezigqokile, bese usebenzisa i-silicon nitride ukuhlanganisa nezitini ze-silicon nitride. Imikhombe ye-aluminium egelezayo nezindawo ze-aluminium ziklanywa kanzima yi-aluminium encibilikisiwe. Ngokuvamile, kusetshenziswa izitini zokuzibopha noma i-silicon nitride eboshwe nge-silicon carbide, futhi izitini ze-zircon zisetshenziswa njengama-linings. Ulwelwesi lwesithando somlilo olungathinti i-aluminium encibilikile ngokuvamile lusebenzisa izitini zobumba, izinto zokubumba ezakhiwe ngobumba noma amapulasitiki aphikisayo.

I-induction furnace lining material yokuncibilikisa i-aluminium kanye ne-aluminium alloys imvamisa iyinto ephezulu ye-high-aluminium eyomile, noma i-silicon carbide ingezwa ezintweni ze-alumina dry ramming, ezingajwayele ukuvuza okungamanzi.
