Ngakanani udaka oluphikisayo oludingekayo ukwakha izitini ezikhanyisayo?
Ngakanani udaka oluphikisayo oludingekayo ukwakha izitini ezikhanyisayo?
Izitini ezi-Refractory yizinto ezisemqoka ekwakhiweni kwamahhavini ezimboni kanye nama-kilns. Ngaphambi kokubeka izitini ezinenkani, lungisa udengezi olusetshenzisiwe. Usayizi wezinhlayiyana ophelele we-slurry akufanele weqe ama-20% amajoyinti wokwakha. Izici zomzimba nezamakhemikhali zodaka kufanele zihambisane nohlobo nekhwalithi yezitini ezikhombayo. Lapho uthenga izitini ezinenkani, kungcono ukuqoka umenzi ukuthi alungiselele udaka oluhambisanayo lokuvikela ukuvimbela ukuxuba.
Procedures: Izinqubo zokulungisa udaka eziphikisayo
Izidingo ezijwayelekile zokulungiswa kodaka oluphikisayo kufanele lincike ohlotsheni lwamatshe, futhi ukungaguquguquki nokuqukethwe kuketshezi kwesilayidi kufanele kunqunywe ngokususelwa ekuhlolweni. Ngasikhathi sinye, hlola ukuthi izakhiwo zokwakha (isikhathi sokubopha) se-grout ziyahlangabezana yini nezidingo zokwakhiwa kwamatshe. Isikhathi sokubopha se-grout sincike entweni nasosayizi womkhiqizo we-Refractory, ngokuvamile akufanele weqe imizuzu emi-2, futhi inombolo nokuvumelana kwama-grouts ahlukene kukhethwe ngohlobo lwamatshe.
Ukunqunywa kokuqina kodaka kuzokwenziwa ngokuya ngezidingo zenqubo yamanje yomkhakha kazwelonke “Indlela Yokuhlola Yokuqina Kodaka Okuphikisayo”. Isikhathi sokubophela slurry sinqunywa ngokuya ngezidingo zezinga lamanje lomkhakha kazwelonke “Indlela Yokuhlola Yesikhathi Sokuhlanganisa Udaka Esiphikisayo”.
Kunezindlela ezimbili zokulungiselela udaka: inhlanganisela yemvelo yamanzi nokuhlanganiswa kwamakhemikhali. Ekubunjweni kwamathanga ezimboni nezinsika, iningi lazo lilungiswa ngokuhlanganiswa kwamakhemikhali, futhi kufakwa i-coagulant ehambisanayo. Kubonakala ngejubane lokuqina okusheshayo, amandla okusondelana okuphezulu, futhi akukho brittleness ngemuva kokuncibilika ekushiseni okuphezulu. Kodwa-ke, ngemuva kokusetshenziswa kwamatshe odaka oluboshwe ngamanzi, amanzi asezingeni eliphakeme kakhulu kuhhavini avuthisa amandla, ukwakhiwa kodaka kulula ukuba kube brittle, futhi ukwakhiwa kwamatshe akuqinile. Ngaphezu kwalokho, i-slurry ekhanyayo elungiselelwe ngosuku olufanayo kufanele isetshenziswe ngosuku olufanayo.
2: Indlela yokubala yokusetshenziswa kodaka okukhanyelayo
Njengamanje, ayikho indlela enhle yokulinganisa isidingo sodaka oluphikisayo lwaso sonke isithando sezimboni. Ngenxa yezinhlobo ezahlukahlukene zamahhavini nezitini zezimboni, kuyenzeka ukuthi kwakhiwe izitini ezenzelwe ukumisa ezikhethekile. Izitini ezingajwayelekile zokukhomba noma izikhundla zokwakha zehlukile, futhi nenani lodaka lokuphikisa elisetshenziselwa ukwakhiwa kwezitini okukodwa odongeni lwesithando nalo lihlukile. Ingaphansi lesithando somlilo lihlukile. Njengamanje, isisekelo sokusetshenziswa kobumba olukhanyayo kusabelomali noma ukulinganiselwa kobunjiniyela besithando sezimboni yizitini ezijwayelekile zokuphikisa ezisetshenziselwa ukwakhiwa kwezindonga zesithando somlilo. Ngaphezu kwalokho, kufanele kubhekiswe ezinhlanganisweni zodaka lokwakha, okuyipharamitha eyisisekelo yokulinganisa udaka oluphikisayo olusetshenziswe ezitini ezijwayelekile zokuphikisa. Amalunga odaka wamatshe kufanele abekwe kuqala. Umphetho womlotha webanga lokuqala ungaphansi kuka-1mm, umthungo womlotha osezingeni eliphansi ungaphansi kuka-2mm, kanti umthungo womlotha osezingeni lesithathu ungaphansi kuka-3mm. Ezinhlotsheni ezintathu zamalunga odaka, amalunga odaka wesibili ajwayele ukusetshenziselwa izitini ezakhiwe ngobumba noma izitini eziphakeme ze-alumina ezikhanyisayo.
Isibonelo, ukubala inani eliphelele lodaka lokuphikisa oludingekayo ezingcezwini eziyi-1000 zezitini eziphakeme ze-alumina ezikhanyisayo, indlela yokubala kumele yaziwe kuqala: a = udaka lwamatshe oluhlangene (2mm) B = indawo yosayizi wezitini ohlangothini olulodwa (usayizi we-T-3 230 * 114 * 65)
C = ikhwalithi yodaka olusetshenziswayo olusetshenzisiwe (ubukhulu bodaka oluphezulu lwe-alumina ngu-2300kg / m3) d = inani lodaka oludingekayo kwisitini ngasinye. Ekugcineni, ukusetshenziswa kodaka d = 230 * 114 * 2 * 2500 = 0.13kg (ukusetshenziswa ngebhulokhi ngayinye). Ukusetshenziswa okuphelele kwezitini eziyi-1000 eziphakeme ze-alumina ezicashuniwe cishe kungu-130kg wesilayidi esikhanyisayo. Le ndlela yokubala iyindlela eyisisekelo yokubala, futhi ukusetshenziswa kwayo okuqondile kufanele kube ngaphezu kwe-10% yedatha yemfundiso.
