Ibhola elikhanyayo (ibhola lokugcina ukushisa)
Ibhola elikhanyayo (ibhola lokugcina ukushisa)
1.Ibhola eliphakeme le-alumina linezimpawu zokumelana ne-oxidation okuqinile nokumelana ne-slag. Ibhola lobumba elikhanyayo lingashintshwa futhi lihlanzwe kalula, futhi lingasetshenziswa futhi.
2. Ukucaciswa okuyinhloko kwebhola eliyikhonji: Φ40mm Φ50mm Φ60mm Φ70mm
3. Izinto zokwenziwa zemikhiqizo yebhola elikhanyelayo zehlukaniswe: i-high-aluminium, i-corundum, ne-zirconium corundum.
4. Kunezinhlobo eziningi zamabhola we-refractory, angasetshenziswa kumakhaza okuguqula ukushisa okuphezulu naphansi, ama-reformers, ama-hydrogenation converters, amathangi we-desulfurization, namabhola we-refractory kanye nemishini yokuguqula ukushisa efakwe esikhundleni somlilo oshisayo embonini yensimbi nensimbi .
5. Amabhola we-porcelain wesitoreji sokushisa anezinzuzo zamandla aphezulu nokugqoka ukumelana; ukuqhutshwa okukhulu okushisayo namandla okushisa, ukusebenza kahle kokugcina ukushisa; amabhola we-porcelain wokugcina ukushisa anokuqina okuhle kokushisa futhi akulula ukugqashuka lapho ukushisa kushintsha ngokuzumayo. Ibhola lokugcina ukushisa lilungele ikakhulukazi ukugcwaliswa kwesitoreji sokushisa kwesitoreji sokushisa kwemishini yokuhlukanisa umoya kanye nesithando somlilo sokushisa kwesithando somlilo sensimbi. Ibhola lokugcina ukushisa likuphinda kabili ukushisa kwegesi nomoya, futhi ibhola lokugcina isitoreji sokushisa lenza ukushisa komlilo kufinyelele ngokushesha ensimbi egingqekayo ukushisa i-billet. Izidingo.
6. Amabhola we-alumina aphezulu e-ceramic refractory, okuqukethwe okuphezulu kwe-alumina, ukuminyana okuphezulu, amandla aphakeme womshini, ukumelana nokugqoka okuhle, izakhiwo zamakhemikhali ezizinzile, ukumelana nokushisa okuhle kakhulu, amabhola aphezulu e-alumina ceramic asetshenziswa kabanzi, futhi angasetshenziswa njengokugcwalisa amakhemikhali. Amabhola aphezulu e-alumina ceramic nawo angasetshenziswa njengemidiya yokugaya. Amabhola aphezulu we-alumina ceramic refractory asetshenziswa kabanzi kumakhemikhali, imishini, i-elekthronikhi, ukuvikelwa kwemvelo kanye neminye imikhakha.
1. Ibhola elikhanyayo le-aluminium ephezulu libhekisa kokuqukethwe kwe-Al2O3. Iphuzu elidumile okuqukethwe kwe-aluminium oxide entweni eluhlaza yebhola elikhanyayo. Okuqukethwe kwe-aluminium kunquma izinga lezinye izakhiwo ezahlukahlukene. Ngakho-ke, kuyinkomba yokusebenza eyinhloko yebhola lokuphikisa. Amabhola we-high-aluminium refractory angahlukaniswa abe izinhlobo ezine ngokuya ngokuqukethwe kwe-aluminium: izinga lokuqala lokuqukethwe kwe-aluminium ephezulu 75; amabhola esezingeni eliphakeme e-aluminium ephezulu, i-ZN-65 enokuqukethwe kwe-aluminium okungama-65%; ezingeni lesithathu amabhola e-aluminium aphezulu, nokuqukethwe kwe-aluminium 55% I-ZN-55.
2. Ubuningi besibalo isilinganiso sobunzima obomile bebhola eliyikhonoli ukuya kumthamo walo ophelele, futhi iyunithi lingu-g / cm3. Ubuningi besibalo ikakhulu bukhombisa ukubumbana kwebhola eliyikhonji. Ngokuvamile, ukuminyana kwenqwaba yamabhola aphikisayo kuhlobene kakhulu ne-porosity kanye nokwakheka kwamaminerali. Ebholeni lokuphikisa, ukuphakama kobuningi kuyanda, ngcono ikhwalithi yomkhiqizo. Ubuningi bevolumu yezinhlobo ezine zamabhola aphikisayo yilawa: ibanga lokuqala ibhola eliphakeme le-alumina ≥ 2.5; ibanga lesibili ibhola eliphakeme le-alumina ≥ 2.3; ibanga lesithathu ibhola eliphakeme le-alumina ≥ 2.1.
3. I-porosity ebonakalayo isilinganiso sevolumu yamaphoyinti avulekile ebhola lokuphikisa kuvolumu ephelele. Ngokuvamile, i-slag negesi eyingozi esithandweni idonsa ibhola elikhanyayo uqobo ngokusebenzisa izimbobo ezivulekile. Ngakho-ke, kuyadingeka ukuthi i-porosity ebonakalayo yebhola lokuphikisa incane ngangokunokwenzeka. I-porosity ebonakalayo yezinhlobo ezine zamabhola we-refractory yilezi: ezingeni lokuqala le-high-aluminium balls≤24%; ezingeni lesibili amabhola aphezulu e-aluminium≤26%; ezingeni lesithathu ama-high-alumina balls≤28%.
4. Iyunithi ivezwa ngeKN. Amanani wokumelana nengcindezi ezinhlobo ezine zamabhola we-refractory ekamelweni lokushisa yilezi: ibhola elikhethekile le-aluminium ephezulu ≥ 25; ibanga lokuqala ibhola eliphakeme le-aluminium ≥ 15; ibanga lesibili ibhola eliphakeme le-aluminium ≥ 10; ibanga lesithathu ibhola le-aluminium ephezulu ≥ 8.
5. Ukushisa okuthambisa umthwalo webhola elikhanyelayo kubhekisa ezingeni lokushisa lapho likhubazeka khona ngesikhathi sokusetshenziswa. Ukushisa okuthambisa umthwalo wezinhlobo ezine zamabhola aphikisayo yilawa: amabhola akhethekile ebanga eliphakeme le-aluminium ≥1530 ℃; ibanga lokuqala le-high-aluminium amabhola ≥1480 ℃; amabanga wesibili ephezulu-aluminium amabhola ≥1450 ℃; namabhola ebanga lesithathu ephezulu-aluminium ≥1400 ℃.
6. Ukuqina kokushaqeka okushisayo yikhono lebhola elikhaliphile ukumelana nezinguquko zokushisa ekushiseni okusheshayo nokubanda okusheshayo. Ukukala le nkomba yokusebenza kwebhola eliyikhonji, kuvamise ukuvezwa kaningi ngaphansi kwesimo sokupholisa amanzi okungu-1100 ℃. I ezishisayo ukushaqeka ukuzinza izinhlobo ezine amabhola refractory yilezi: ekhethekile eliphezulu alumina ibhola times izikhathi 10; ibanga lokuqala i-alumina ball ephezulu, ibanga lesibili i-alumina ball ephezulu, nebanga lesithathu i-alumina ball ephezulu times izikhathi eziyi-15.
Izinkomba eziyisikhombisa, zomzimba nezamakhemikhali:
