Izitini ze-CCEFIRE® DEM Series Mullite ezibonakala ngokuphikiswa okuphezulu okungafinyelela ngaphezu kuka-1790C. Izinga lokushisa lokuthambisa umthwalo liphakathi kuka-1600 ~ 1700℃. Amandla okucindezela ekushiseni okujwayelekile angama-70 ~ 260MPa. Ukumelana okuhle nokushaqeka kokushisa.
Ikhwalithi Yomkhiqizo Ezinzile
Ukulawulwa okuqinile kwezinto zokusetshenziswa
Lawula okuqukethwe kokungcola, qinisekisa ukuncipha kokushisa okuphansi, futhi uthuthukise ukumelana nokushisa
1. Unesisekelo esikhulu se-ore, imishini yokumba yobungcweti, kanye nokukhethwa okuqinile kwezinto zokusetshenziswa.
2. Izinto zokusetshenziswa ezingenayo ziyahlolwa kuqala, bese izinto zokusetshenziswa ezifanele zigcinwa endaweni yokugcina impahla eluhlaza ekhethiwe ukuqinisekisa ubumsulwa bazo.
Ukulawulwa kwenqubo yokukhiqiza
Nciphisa okuqukethwe kwamabhola e-slag, qinisekisa ukuthi ukushisa kuphansi, futhi uthuthukise ukusebenza kokushisa
1. Kukhona i-mullite ehlanganisiwe kanye nezitini ze-mullite ezihlanganisiwe.
2. Izinto eziyinhloko zokusetshenziswa kwezitini ze-mullite ezisikiwe yi-clinker ene-bauxite ephezulu ngokufaka inani elincane lobumba noma i-bauxite eluhlaza njenge-binder eyenziwe ngokubumba nokusikwa.
3. Izinto ezisetshenziswa kakhulu zezitini ze-mullite ezihlanganisiwe yi-bauxite ephezulu, i-alumina kanye nobumba oluyi-refractory, ngokufaka ama-charcoal noma ama-coke fines njenge-reducing agent. Ngemva kokubumba kusetshenziswa indlela yokunciphisa ukukhiqiza.
4. Ukwakheka kwe-mullite ehlanganisiwe kukhulu kune-mullite ehlanganisiwe futhi ukumelana nokushaqeka kokushisa kungcono kunemikhiqizo ehlanganisiwe.
5. Ukusebenza kwezinga lokushisa eliphezulu kuncike kakhulu enanini lokuqukethwe kwe-alumina kanye nokufana kokusatshalaliswa kwe-mullite nengilazi.
Ikhwalithi yokulawula
Qinisekisa ubuningi obukhulu futhi uthuthukise ukusebenza kokuvikela ukushisa
1. Ukuthunyelwa ngakunye kunomhloli wekhwalithi ozinikele, futhi kunikezwa umbiko wokuhlola ngaphambi kokuhamba kwemikhiqizo efektri ukuqinisekisa ikhwalithi yokuthunyelwa ngakunye kwe-CCEFIRE.
2. Ukuhlolwa komuntu wesithathu (njenge-SGS, i-BV, njll.) kuyamukelwa.
3. Ukukhiqizwa kuhambisana ngokuqinile nesitifiketi sohlelo lokuphathwa kwekhwalithi ye-ASTM.
4. Iphakheji yangaphandle yebhokisi ngalinye yenziwe ngezingqimba ezinhlanu zephepha lokubhaka, kanye nephakheji yangaphandle + iphalethi,, efanelekile ukuthuthwa ibanga elide.
Izici Ezivelele
Izici ze-CCEFIRE DEM Series Mullite Brick:
Kukhona i-mullite ehlanganisiwe kanye nezitini ze-mullite ezihlanganisiwe. Izinto eziyinhloko zokusetshenziswa kwezitini ze-mullite ezihlanganisiwe yi-clinker ye-bauxite ephezulu ngokufaka inani elincane lobumba noma i-bauxite eluhlaza njenge-binder eyenziwe ngokubumba nokubumba. Izinto eziyinhloko zokusetshenziswa kwezitini ze-mullite ezihlanganisiwe yi-bauxite ephezulu, i-alumina kanye nobumba oluphikisayo, ngokufaka amalahle noma ama-coke fines njenge-ejenti yokunciphisa. Ngemva kokubumba kusetshenziswa indlela yokunciphisa ukukhiqiza. Ukwakheka kwe-mullite ehlanganisiwe kukhulu kune-mullite ehlanganisiwe futhi ukumelana nokushaqeka kokushisa kungcono kunemikhiqizo ehlanganisiwe. Ukusebenza kwezinga lokushisa eliphezulu kuncike kakhulu enanini lokuqukethwe kwe-alumina kanye nokufana kokusatshalaliswa kwe-mullite nengilazi.
Isicelo se-CCEFIRE DEM Series Mullite Brick:
Isetshenziswa kakhulu phezulu kwesitofu esishisayo, umzimba wesitofu esishisayo kanye nesisekelo sesithando, i-regenerator yesithando seglasi, isitofu esishisayo, kanye nohlelo lokufaka uphethiloli ekhoneni.
Ukwakheka okuhle kanye nokuhlanzeka okuphezulu kwezitini ze-mullite kwenza zitholakale ukuze zisetshenziswe ezimweni ezimbi kakhulu. Izinhlelo ezinjalo zilandelayo:
Imboni yamakhemikhali,
Imboni yengilazi,
Isishisi: singcoliswe kakhulu yimfucuza negesi.
Siza ukuthi ufunde izinhlelo zokusebenza ezengeziwe
