Izitini Zobumba
IMIKHIQIZO
SK32-36 Clay Blacks
Incazelo Eningiliziwe
Ukwakhiwa kwamaminerali ezitini zobumba ikakhulukazi i-kaolinite (Al2O3 · 2SiO2 · 2H2O) kanye nokungcola okungu-6% ~ 7% (i-potassium, i-sodium, i-calcium, i-titanium, i-iron oxides). Inqubo yokudubula yezitini zobumba ngokuyinhloko inqubo ye-kaolinite yokubola nokwenza amakristalu e-mullite (3Al2O3 · 2SiO2) ngokusebenzisa ukuphelelwa amandla kwamanzi okuqhubekayo. Phakathi nenqubo yokudubula, i-SiO2 ne-Al2O3 ezitini zobumba zakha i-eutectic low-melting silicates enokungcola, ezungeze amakristalu e-mullite.
Izitini ze-clay refractory zihlukaniswe kakhulu zibe izitini zobumba eziphikisayo zokushisa iziqhumane, izitini zobumba eziphikisayo zokushisa okushisayo, kanye nezitini ezinkulu zobumba eziphikisayo zokushisa ingilazi ngokuvumelana nokusetshenziswa kwazo.
Izitini ze-clay refractory ze-blast furnaces
Izitini ze-clay refractory ze-blast furnaces ziyizitini zobumba ezenziwe ngobumba oluphikisayo njengezinto ezingavuthiwe futhi ezisetshenziselwa ukwakha amalayini omlilo oqhumayo. Izitini zobumba eziphikisayo zomlilo eziqhumayo zisetshenziselwa umphimbo, umzimba, iziko, phansi kwezingqimba ezincane zesithando somlilo kanye nomzimba wezithando zomlilo ezinkulu.
Izitini ze-clay refractory ze-blast furnaces zidinga amandla aphezulu okuphikisa ekamelweni lokushisa futhi zingamelana nokusebenza isikhathi eside nokuguga kwenkokhelo; ukuncipha kwevolumu encane ngaphansi kokushisa okuphezulu nokusebenza isikhathi eside, okulungele ukugcina ubuqotho be-lining; i-porosity ebonakalayo ephansi kanye ne-Fe:O. Okuqukethwe okuphansi, ukunciphisa i-carbon deposition kuma-pores, ukugwema ukunwetshwa nokuxegiswa kwezitini eziphikisayo ngesikhathi sokusetshenziswa nokulimala; kwakheka izinto ezincibilika kancane. Izitini eziphikisayo zobumba zeziko eziqhumayo zisebenza kangcono kunezitini zobumba ezijwayelekile. [2]
Izitini ze-clay refractory zezindawo zokushisa ezishisayo
Izitini zobumba zezithando zomlilo ezishisayo zenziwe ngobumba oluphikisayo futhi zisetshenziselwa ukwakha amafunu omlilo ashisayo. Izitini zobumba zezindawo zokushisa ezishisayo zisetshenziswa ezithandweni ezishisayo, emakamelweni okugcina ukushisa kanye nezindonga zokuhlukanisa. Izitini zobumba zezithando zomlilo ezishisayo ziyadingeka ukuze zibe nokumelana nokushaqeka okuhle kokushisa, izinga lokushisa eliphezulu lokuthambisa umthwalo kanye nokukhasa okuncane.
I-China 3) Izitini ze-clay refractory ze-hot blast furnaces zihlukaniswa ngamamaki amathathu ngokusho kwezinkomba zomzimba namakhemikhali: i-RN-42, RN-40 ne-RN-36. Izinkomba zomzimba namakhemikhali kanye nokubekezelelana kwe-dimensional zimi kanje:
(1) Lapho ububanzi bokuqhekeka kongqimba bungekho ngaphezu kuka-0.25mm, ubude abunqunyelwe;
(2) Lapho ububanzi bokuqhekeka kongqimba bungu-0.26-0. 50mm, ubude abukho ngaphezu kuka-30mm;
(3) Uma ububanzi bokuqhekeka kongqimba bukhulu kuno-0.50mm, abufanelekile. [3]
Izitini ezinkulu zobumba eziphikisayo zokushisa ingilazi
Izitini ezinkulu zobumba eziphikisayo zokokhela izingilazi ziyizitini ezinobumba ezinesisindo esingekho ngaphansi kuka-50kg ezisetshenziselwa ukwakha ooko bezingilazi.
