Kev ziab, cua sov thiab tu cov cement kiln castables
Lub hardened los yog qhuav castable tseem muaj cov seem ntawm lub cev thiab tshuaj dej, thiab ces nws yog rhuab mus rau 300 ℃ mus vaporize thiab dehydrate, thiab tag nrho cov dej yuav tawm. Vim tias cov castable muaj cov qauv ntom ntom, cov cua sov yuav tsum tau qeeb kom tsis txhob kub siab. Kev ntxhov siab tshwm sim los ntawm qhov nrawm nrawm ntawm qhov siab thiab noo noo ua rau kev puas tsuaj ntawm cov castable.
Lub tshuab ziab khaub ncaws thiab cua sov ntawm lub tshuab hluav taws xob qee zaum tsis tuaj yeem ua tau raws li qhov xav tau kom qhuav ntawm preheater thiab calciner (grate cooler, kiln hood thiab tertiary air duct raws li qhov ziab thiab cua sov ntawm lub qhov cub, thiab tsis tau teev tseg), yog li ntawd, Lub ci cua sov ntawm lub kiln system hais hauv qab no yuav tsum tau ua ke nrog cov kev cai ntawm ntu no. Yog hais tias qhov kub ntawm lub kiln system nce mus txog 600 ° C (nyob rau hauv qhov kub ntawm cov pa tso pa tawm ntawm lub qhov cub), thawj preheater tsis tau raws li qhov yuav tsum tau kom qhuav, thiab lub sij hawm preservation ntawm lub kiln system ntawm 600 ° C yuav tsum. raug ncua.
Lub sijhawm kho ntawm cov khoom tom kawg ntawm cov khoom siv hluav taws xob tsis pub tsawg tshaj 24h ntawm qhov kub ntawm li 25 ° C (rau cov cement castables tsawg, lub sijhawm kho yuav tsum tau txuas ntxiv mus rau 48h raws li qhov tsim nyog). Tom qab lub castable tau txais ib lub zog, tshem tawm cov formwork thiab kev txhawb nqa. Ci tuaj yeem nqa tawm tom qab 24 teev kom qhuav. Yog tias qhov kub thiab txias qis dhau lawm, lub sijhawm kho yuav tsum tau ncua.
Siv qhov ntsuas kub ntawm cov pa tso pa ntawm lub qhov cub qhov cub raws li tus qauv, thiab siv cov cua kub ntawm 15 ° C / h kom txog thaum nws nce mus txog 200 ° C, thiab khaws cia rau 12 teev.
Tshav kub rau 400 ° C ntawm qhov cua sov ntawm 25 ° C / h, thiab khaws qhov kub tsis pub tsawg tshaj 6h.
Tshav kub rau 600 ° C thiab khaws qhov kub tsis tsawg tshaj 6h. Ob qho xwm txheej hauv qab no yog qhov tsim nyog thiab txaus rau kev ci ntawm calciner thiab preheater system:
Thaum qhov kub ntawm lub refractory castable nyob rau hauv lub pouring qhov ntawm lub cyclone preheater nyob ze ntawm lub silicon cover mus txog 100 ℃, lub sij hawm ziab yuav tsum tsis pub tsawg tshaj 24h.
Ntawm lub qhov rooj manhole ntawm thawj-theem cua daj cua dub preheater, ib daim iav huv si tau siv los tiv thaiv cov pa hluav taws xob, thiab tsis pom cov dej ntws tawm ntawm lub khob. Lub sijhawm khaws cia cua sov yog 6 teev.
