Ama-Castable Angaguqukiyo Okwakha I-Simente Rotary Kiln

Ama-Castable Angaguqukiyo Okwakha I-Simente Rotary Kiln

1. Izinto zokusika eziqinisiwe zensimbi eziqinisiwe ze-fibre ye-samente
Ama-castable aqiniswe ngefayibha yensimbi afaka kakhulu imicu yensimbi engagqwali engamelani nokushisa entweni, ukuze into ibe namandla aphezulu kanye nokumelana nokushaqeka kokushisa, ngaleyo ndlela yandise ukumelana nokuguguleka kanye nokuphila kwesikhathi senkonzo yento. Le nto isetshenziselwa kakhulu izingxenye ezingaguguleki ezishisa kakhulu njengomlomo wesitofu, umlomo wokudla, i-pier engaguguleki kanye nolwelwesi lwebhoyila yesitshalo samandla.

2. Izinto zokulahla eziphansi ze-samente ezingasebenzi kahle ze-samente kiln
Ama-castable angenasimende esiphansi ahlanganisa kakhulu ama-castable angenasimende esino-alumina ophezulu, i-mullite kanye ne-corundum. Lolu chungechunge lwemikhiqizo lunezici zamandla aphezulu, ukulwa nokukhuhla, ukumelana nokuguguleka kanye nokusebenza okuhle kakhulu. Ngesikhathi esifanayo, izinto zingenziwa ama-castable angenasiphepho abhaka ngokushesha ngokwezidingo zesikhathi sokubhaka somsebenzisi.

3. Izinto zokulahla eziqinile ezimelana ne-alkali zehhavini likasimende
Ama-castable aqinile amelana ne-alkali amelana kahle nokuguguleka yigesi ye-alkali kanye ne-slag, futhi ahlala isikhathi eside. Lokhu okubalulekile kusetshenziselwa kakhulu izembozo zeminyango ye-oven, ama-oven abola, izinhlelo ze-preheater, izinhlelo zokuphatha, njll. kanye nezinye izintambo ze-oven zezimboni.

Indlela yokwakha i-castable ye-aluminium ephezulu enosimende ophansi we-rotary kiln
Ukwakhiwa kwe-castable ye-aluminium ephezulu enosimende ophansi ye-rotary kiln kudinga ukunakwa okukhethekile kulezi zinqubo ezinhlanu ezilandelayo:

1. Ukunqunywa kwamalunga okunwebeka
Ngokusekelwe kokuhlangenwe nakho kwangaphambilini kokusebenzisa ama-castable e-aluminium ephezulu ane-cement encane, ama-expansion joints ayisici esibalulekile esithinta impilo yesevisi yama-linings e-rotary kiln castable. Ama-expansion joints ngesikhathi sokuthululwa kwama-linings e-rotary kiln anqunywa kanje:

(1) Amalunga ajikelezayo: Izingxenye ezingama-5m, i-aluminium silicate fiber felt engu-20mm ibekwe phakathi kwezinto ezifakwayo, futhi imicu iyahlanganiswa ngemva kokunwetshwa ukuze ivimbele ukucindezeleka kokunwetshwa.

(2) Amajoyinti ayisicaba: Yonke imicu emithathu ye-castable ihlanganiswa ne-plywood ejulile engu-100mm ohlangothini olujikelezayo lwangaphakathi, bese kushiywa ijoyinti ekugcineni kokusebenza, ukuze kube nemicu engu-6 iyonke.

(3) Ngesikhathi sokuthulula, kusetshenziswa izikhonkwane zokukhipha umoya ezingu-25 ngemitha yesikwele ukukhulula inani elithile lokucindezeleka kokukhulisa ngenkathi kuqedwa isitofu.

2. Ukunqunywa kwezinga lokushisa lokwakha
Izinga lokushisa elifanele lokwakha lama-castable e-aluminium ephezulu ane-cement ephansi lingu-10~30℃. Uma izinga lokushisa elizungezile liphansi, kufanele kuthathwe izinyathelo ezilandelayo:

(1) Vala indawo yokwakha ezungezile, engeza izindawo zokushisa, futhi uvimbele ngokuqinile ukubanda.

(2) Sebenzisa amanzi ashisayo ku-35-50℃ (okunqunywa ukudlidliza kokuhlola okuthululwa endaweni) ukuxuba izinto.

3. Ukuxuba
Nquma inani lokuxuba ngesikhathi esisodwa ngokwekhono lomxube. Ngemva kokuba inani lokuxuba selinqunyiwe, engeza izinto zokubumba esikhwameni kanye nezithasiselo ezincane zephakheji esikhwameni kumxube ngesikhathi esifanayo. Qala ngokuxuba ukuze womise imizuzu emi-2 kuya kwemi-3, bese ufaka u-4/5 wamanzi alinganisiwe kuqala, uvuselele imizuzu emi-2 kuya kwemi-3, bese unquma u-1/5 wamanzi asele ngokwe-viscosity yodaka. Ngemva kokuxuba ngokuphelele, kwenziwa ukuhlolwa kokuthululwa, futhi inani lamanzi engeziwe linqunywa ngokuhambisana nesimo sokudlidliza kanye nokulunywa. Ngemva kokuba inani lamanzi engeziwe selinqunyiwe, kumele lilawulwe ngokuqinile. Ngenkathi kuqinisekiswa ukuthi ulunywa lunganyakaziswa, kufanele kwengezwe amanzi amancane ngangokunokwenzeka (inani lokwengeza amanzi elibhekiselwe kulokhu okuthululwayo lingu-5.5%-6.2%).

4. Ukwakhiwa
Isikhathi sokwakhiwa kwe-castable ye-aluminium ephezulu enosimende ophansi cishe imizuzu engama-30. Izinto eziphelelwe amanzi noma ezihlanganisiwe azikwazi ukuhlanganiswa namanzi futhi kufanele zilahlwe. Sebenzisa induku edlidlizayo ukuze udlidlize ukuze ufinyelele ukuqina kwe-slurry. Induku edlidlizayo kufanele igcinwe ukuze kuvinjelwe induku eyisipele ukuthi isebenze lapho induku edlidlizayo yehluleka.
Ukwakhiwa kwezinto eziphoswayo kufanele kwenziwe ngemichilo eceleni kwe-axis yesithando esijikelezayo. Ngaphambi kokuthululwa kwestrip ngayinye, indawo yokwakha kufanele ihlanzwe futhi kungabikho uthuli, i-welding slag kanye nezinye izinsalela okufanele zishiywe. Ngesikhathi esifanayo, hlola ukuthi ngabe ukushintshwa kwe-anchor kanye nopende we-asphalt ongaphezulu kuyasebenza yini. Ngaphandle kwalokho, kufanele kuthathwe izinyathelo zokulungisa.
Ekwakhiweni komcu, ukwakhiwa komzimba wokubumba umcu kufanele kuthululwe obala kusukela emsileni wesithando kuya ekhanda lesithando phansi komzimba wesithando. Ukusekelwa kwesifanekiso kufanele kwenziwe phakathi kwe-anchor nepuleti lensimbi. Ipuleti lensimbi ne-anchor kufakwe ngokuqinile ngamabhulokhi enkuni. Ukuphakama kwefomu lokusekela kungu-220mm, ububanzi bungu-620mm, ubude bungu-4-5m, kanti i-engeli ephakathi ingu-22.5°.
Ukwakhiwa komzimba wesibili wokubumba kufanele kwenziwe ngemva kokuba umugqa usuqediwe futhi isikhunta sesisusiwe. Ngakolunye uhlangothi, ithempulethi elimise okwe-arc lisetshenziselwa ukuvala ukubumba kusukela ekhanda lesithando kuya emsileni wesithando. Okunye kuyafana.
Uma izinto zokubumba zinyakaziswa, udaka oluxubile kufanele lufakwe esikhumbeni sethayi ngenkathi lunyakaziswa. Isikhathi sokudlidliza kufanele silawulwe ukuze kungabikho amabhamuza asobala ebusweni bomzimba wokubumba. Isikhathi sokubumba kufanele sinqunywe izinga lokushisa elizungezile lendawo yokwakha. Kubalulekile ukuqinisekisa ukuthi ukubunjwa kwenziwa ngemva kokuba izinto zokubumba sezilungisiwe futhi zinamandla athile.

5. Ukubhaka indwangu
Ikhwalithi yokubhaka ye-rotary kiln ye-rotary kiln ithinta ngqo impilo yokusebenza ye-lining. Enqubweni yokubhaka yangaphambilini, ngenxa yokuntuleka kolwazi oluvuthiwe kanye nezindlela ezinhle, indlela yokufaka uwoyela osindayo wokushisa yayisetshenziswa ezinqubweni zokubhaka ezisezingeni eliphansi, ezisezingeni eliphakathi kanye nezisezingeni eliphezulu. Izinga lokushisa kwakunzima ukulilawula: lapho izinga lokushisa lidinga ukulawulwa ngaphansi kuka-150℃, uwoyela osindayo akulula ukuwushisa; lapho izinga lokushisa liphakeme kuno-150℃, isivinini sokushisa sishesha kakhulu, futhi ukusatshalaliswa kwezinga lokushisa ku-kiln akulingana kakhulu. Izinga lokushisa le-lining lapho kushiswa khona uwoyela osindayo liphakeme cishe ngo-350~500℃, kuyilapho izinga lokushisa lezinye izingxenye liphansi. Ngale ndlela, i-lining kulula ukuyiqhuma (i-lining yangaphambilini engasetshenziswa iqhume ngesikhathi senqubo yokubhaka), okuthinta impilo yokusebenza ye-lining.
