I-alumina ephezulu imelana nokugqokwa
i-refractory castable

Isetshenziswa kabanzi kuma-thermal kilns ahlukahlukene

I-alumina ephezulu engagqoki engagqoki iyi-amorphous refractory castable enokuqukethwe kwe-aluminium iyonke engaphezu kuka-75%, eyakhiwe ngenhlanganisela ephezulu ye-alumina enokuqukethwe kwe-Al2O3 okungaphezu kuka-75% njengento eluhlaza eyimbudumbudu, ehlanganiswe nempushana ephezulu ye-alumina kanye nezithasiselo. .Ngemuva kokumiswa kokuqala kwe-alumina ephezulu ekwazi ukuphonswa, igcinwa ku-28d ngokwejwayelekile, futhi amandla okucindezela angafinyelela ku-40 ~ 60MPa.Ibonakala ngesivinini esisheshayo se-hydration, amandla aphezulu kanye nokumelana nomlilo okuphezulu esigabeni sakamuva.I-alumina ephezulu ekwazi ukumelana nokugqoka inezici ze-anti permeability, ukumelana nokugqwala komthelela, ukumelana nokugqokwa kanye nezakhiwo ezinhle zemishini Isetshenziswa kabanzi ngaphambili nangemuva kwamakhothamo, iziqongo zesithando somlilo, izindonga zesithando somsila nezinye izingxenye zama-boilers we-utility kanye nezinye izinto zokushisa ezishisayo. .

Ukusetshenziswa komkhiqizo

Izindaba ezidinga ukunakwa

● Yomisa ukuhlanganisa kuqala, bese kuba manzi ukuxuba namanzi.Engeza amanzi anele ukuxutshwa okumanzi ngesikhathi esisodwa.Ungafaki amanzi ngokuthanda kwakho.

● Isikhathi sokuxuba sincike esimweni sokuxuba futhi akumele sibe ngaphansi kunesikhathi esincane esidingekayo sokuxuba.Kuphela ngemva kokuba zonke izinto zixubene ngokugcwele lapho kungafinyelela umphumela wokusetshenziswa ovamile.

● Uma kungekho mixer noma izimo zingavumeli, lapho ukuxuba okwenziwa ngesandla kuyadingeka, isikhathi sokuxuba sizonwetshwa ukuze kuqinisekiswe ukuthi izinto zixutshwe ngokugcwele.

● Sicela usebenzise izinto ezixutshiwe phakathi nemizuzu engama-30.Ngemuva kwemizuzu engama-30, ukusebenza kwempahla kuyashintsha futhi ngeke kusetshenziswe.Sicela ulahle imali eningi.

Ukusetshenziswa kanye nomthamo

● Vula iphakheji, uthele izinto kanye nezixube ku-mixer, uhlanganise owomile bese ugoqa imizuzu engu-1-3 ukuze uhlanganise ngokugcwele.

● Faka amanzi anele (cishe u-10% wamanzi okuphuza agaywayo) ngesikhathi esisodwa, ungafaki amanzi ngokuthanda kwakho, hlanganisa okumanzi imizuzu emi-3-5, bese uwaxuba ngokugcwele.

Lezi zixhumanisi ezine ezibalulekile ezilandelayo kufanele zinakwe ekusetshenzisweni kwe-refractory castable, okungukuthi ukuxuba, ukuthela, ukuphulukisa nokubhaka.

Noma iyiphi inkinga kunoma isiphi isixhumanisi ingase iholele ekonakaleni kokusebenza komkhiqizo noma ekuhlulekeni kokusebenzisa.

Ukuxuba

Ukuxuba kuhlukaniswe ngokuxutshwa kwemishini kanye nokuxuba ngesandla.Njengamanje, izixube eziphoqelelwe noma zodaka zisetshenziswa embonini ukuxuba izinto, futhi ukuxuba ngesandla akusetshenzisiwe Izinsiza namathuluzi: izixube eziphoqelelwe noma zodaka, amabhakede, izikali, izidlidlizi, amafosholo amathuluzi, amatroli, njll.

Ukusetshenziswa kwamanzi okwakhiwa kusekelwe ekusetshenzisweni kwamanzi okukhonjiswe eshidini lokuhlola ikhwalithi yeqoqo lemikhiqizo, futhi kusetshenziswa ngokuqinile ngokuvumelana nezindinganiso zokuzuza ukukalwa okunembile.

Ukuxuba: Hlanganisa owomile kuqala bese umanzi.Faka izinto eziningi ku-mixer bese womisa imizuzu engu-1-3 ngokulandelana kwesikhwama esikhulu kuqala bese ufaka isikhwama esincane ukuze usihlanganise ngokulinganayo.Isisindo sokuxuba ngakunye sinqunywa ngokusho kwemishini kanye nevolumu yokwakha;ngokwesisindo sezinto ezibonakalayo, amanzi adingekayo ekuxubeni ngakunye akalwa ngokunembile ngokusho kokusetshenziswa kwamanzi okucacisiwe, angezwe ezintweni ezomile ezixutshwe ngokulinganayo, futhi ashukunyiswe ngokuphelele.Isikhathi asikho ngaphansi kwe-3min, ukuze sibe noketshezi olufanele, bese impahla ingakhishwa ukuze ithulule.

Ukuthela

Ngaphambi kokuba izinto zokuthulula zakhiwe, kuyadingeka ukuhlola ukuthi amahange ashiselwe ngokuqinile, futhi izipikili ezimelana nokushisa kufanele zisetshenziswe izingxenye ezingaphezu kuka-500C.Ingaphezulu lehange kufanele lipendwe ngopende owugqinsi ongu-0. 5-1mm noma usongwe ngetheyiphu yepulasitiki ukuze unciphise amandla okunweba ngemva kokushisisa nokukhipha udoti esikhunjeni.

I-castable esanda kuxutshwa kufanele ithululwe ngokushesha, ngokuvamile kungakapheli imizuzu engama-20.Thela okuxubekile okuxubekile esikhunjeni, bese ufaka isidlidlizi ku-vibrator ngesikhathi, futhi isidlidlizi kufanele sifane.Lapho ingaphezulu le-castable li-slurried, ama-bubbles ayakhishwa.Lapho ubuso bugcwele, induku yokudlidliza iyasuswa, futhi isivinini esihambayo singu-1-2m/min.Lapho induku edlidlizayo ikhishwa, ijubane lihamba kancane.

Ngaphambi kokuthi ukuqina kuqedwe ngemva kokuthululwa, izinga lokushisa lendawo kufanele ligcinwe lingaphezu kuka-10C(10-30.C).Uma izinga lokushisa lendawo lingaphansi kuka-0'C, kufanele kuthathwe izinyathelo zokushisisa nokugcina ukushisa okuhambisanayo, ngaphandle kwalokho kuzodala ukungasebenzi futhi kuholele ekonakaleni komkhiqizo.

Isondlo

Amathuluzi ayinhloko asetshenziswa ifilimu yepulasitiki ye-polyethylene, izikhwama zotshani, njll. Izidingo zokushisa ezizungezile kanye nokulawula: Izinga lokushisa elipholile lomzimba ophonsa kungcono kakhulu libe phakathi kuka-15-35C. ukusebenza komkhiqizo kuzoncishiswa.

Ngemuva kokuthi i-castable iqinisiwe, kuyadingeka ukumboza ngokushesha ubuso bomzimba wokwakha ngefilimu yepulasitiki ye-polyethylene, bese uyimboza ngesikhwama sotshani esimanzi ukuvimbela ukuhwamuka kwamanzi futhi ukhuthaze ukusebenza kukasimende Ngemva kokuqina, akuvunyelwe ukushaya nokudlidliza ngaphakathi kwesinye. usuku.Ngokusho kwesimo sokuqina, singadilizwa ngemuva kwamahora angama-24-30 wokuqina.

Ngemuva kokudilizwa, kufanele igcinwe izinsuku ezimbili njengoba kudingeka, futhi ifilimu yepulasitiki ye-polyethylene nezikhwama zotshani ezimanzi kufanele zengezwe ngesikhathi sokunakekelwa.Ngemuva kwezinsuku ezintathu zokuphulukisa, susa ifilimu yepulasitiki kanye nesikhwama sotshani.Vumela umzimba oqinile ukuba wome ngokwemvelo emoyeni usuku olulodwa ngaphambi kokubhaka.

Ukubhaka

Ukubhaka kuyisixhumanisi sokugcina esibalulekile ekusetshenzisweni kwama-castable.Njengoba umzimba wokuphonsa uminyene, kwenqatshelwe ngokuphelele ukushisa ngokushesha kakhulu ngesikhathi sokubhaka, ngaphandle kwalokho kuzodala ingozi yokuqhekeka.
