Cov txheej txheem kev tsim kho ntawm lub hauv paus kub-resistant pob zeb, qhov tshiab kub moj tej tawg qhov cub npaj kev qhia tawm ~

Cov txheej txheem kev npaj ua vaj tse ntawm cov blast furnace kub moj tej tawg qhov cub yog sau thiab txheeb los ntawm refractory cib chaw tsim tshuaj paus.

1. Cov txheej txheem tsim kho ntawm lub hauv paus formwork ntawm lub qhov cub kub kub:

(1) Siv cov hlau sib xyaw ua ke los txhawb, thiab cov pwm tuaj yeem siv los ua cov haujlwm ntawm ntug.

(2) Qhov chaw sib cuag ntawm cov pob zeb kub-resistant thiab cov formwork yuav tsum tau coated nrog ib txheej cais.

(3) Cov pob qij txha ntawm cov qauv yuav tsum tau muab kaw, thiab slurry to yog nruj me ntsis txwv.

(4) Tom qab kev them nyiaj yug template tiav lawm, xyuas seb qhov loj, qhov siab, thiab kev txhawb nqa txoj hauj lwm ntawm lub template puas yog, paub meej tias seb qhov nruj thiab ruaj khov ntawm cov txheej txheem txhawb nqa raws li qhov tsim nyog, thiab tom qab ntawd ntxuav cov impurities hauv cov qauv. .

(5) Tom qab tus qauv tsim nyog, cov kev ntsuas hauv qab no yuav tsum tau ua kom muaj kev ruaj ntseg ntawm cov qauv yooj yim vim qhov ntim loj ntawm lub qhov cub kub kub:

1) Lub hauv paus yuav tsum tau txais kev txhawb nqa nrog peb txheej ntawm lub kaum sab xis steel los txhawb cov yeeb nkab txias, formwork thiab steel tuav, thiab lub kaum sab xis steel nrog qhov siab tib yam li lub thickness ntawm lub hauv paus yuav tsum tau txhawb nqa nyob ib ncig ntawm lub hauv paus kom ntxiv dag zog rau lub formwork.

2) Bolts thiab lub kaum sab xis steel sib txuas teeb tsa nyob ib ncig ntawm lub hauv paus yog siv los txhawb lub hauv paus formwork.

3) Lub nro bolts teem rau ntawm lub hauv paus ywj pheej thiab lub hauv paus luv kab tseem siv los txhawb lub hauv paus formwork.

2. Foundation kub-resistant pob zeb cushion:

(1) Ua ntej kev tsim kho ntawm cov pob zeb ua pob zeb, lub hauv paus yuav tsum tau leveled, thiab qhov chaw ntawm lub hauv paus yuav tsum tau ntxuav tom qab leveling.

(2) Rub kab: tso cov kev tsim kho txoj kab ntawm cov pob zeb ua pob zeb thiab kos nws kom meej.

(3) Kev npaj ntawm pob zeb: nruj me ntsis ua raws li cov khoom siv raw khoom sib piv thiab cov dej ntxiv rau hauv phau ntawv qhia kev tsim vaj tsev kom sib tov sib npaug.

(4) Ua ntej cov pob zeb sib xyaw, cov tho steel yuav tsum tau muab tso rau ntawm lub hauv paus kom tswj nws cov tuab. Sab pwm ntawm cov pob zeb cushion txheej yuav tsum tau kho nrog steel xyaum. Thaum lub sij hawm pouring txheej txheem, lub vibrator yuav tsum tau tsim kom vibrate densely, thiab thaum kawg ib tug ntoo trowel yuav tsum tau siv rau theem ntawm lub cushion txheej. deal nrog.

3. Thaum tshav kub kub-resistant qhob kev tsim kho ntawm kub blast qhov cub foundation:

Kev tsim kho ntawm cov pob zeb kub-resistant yuav tsum ua kom tiav ntau li ntau tau nyob rau hauv ib lub sij hawm, vibrating thiab compacting thaum pouring, thiab tsis muaj expansion pob qij txha.

(1) Kev tsim kho thiab nchuav ntawm cov pob zeb yuav tsum tau ua nyob rau hauv cov txheej txheem, txhua lub thickness ntawm 300 hli, thiab cov pob zeb hauv qab yuav tsum tau nchuav ua ntej pib qhov txheej txheem sab saud.

(2) Lub pob zeb yuav tsum tau vibrated thiab compacted kom txog thaum lub nto tsis pom tseeb sinking, bubbling thiab dej nyab.

(3) Thaum lub sij hawm kev tsim kho vaj tse, xyuas cov qauv, cov hlau tuav, cov qhov tshwj xeeb, cov khoom seem thiab cov ntxig rau kev hloov pauv, deformation lossis thaiv txhua lub sijhawm, thiab kho thiab kho, thiab lawv yuav tsum tau kho ua ntej txheej txheej pob zeb ua tiav. .

(4) Tom qab kev tsim kho ntawm cov pob zeb ua tiav tiav thiab paub tseeb tias tsim nyog, kev saib xyuas yuav pib. Rov ua dej thiab npog thiab kho yuav tsum tau nqa tawm hauv 12 teev. Thaum lub sij hawm tus txheej txheem, txaus noo noo ntawm lub pob zeb txheej yuav tsum tau ensured. Lub sijhawm kho yuav tsum tsis pub tsawg tshaj 7 hnub tag nrho. Thaum lub sij hawm kho, qhov kub thiab txias ntawm cov pob zeb yuav tsum tau tshuaj xyuas thiab sau tseg tsis tu ncua.

4. Kev ntsuas cua txias rau cov pob zeb kub-resistant:

Vim lub ntim loj ntawm cov cua sov-resistant pob zeb txheej ntawm lub qhov cub kub blast lub hauv paus, txhawm rau kom tsis txhob muaj qhov tshwm sim ntawm qhov kub thiab txias, kev ntsuas kom txo qhov kub yuav tsum tau saws:

(1) Thaum npaj pob zeb, ntxiv slag Portland cement thiab basalt / andesite pob zeb kom txo cov dej kub kub.

(1) Cov kav dej txias tau muab tso rau hauv lub hauv paus kom lawv sib npaug sib npaug nrog qhov sib nrug ntawm li 2m.

(2) Ob lub ntsuas kub tau nruab rau ntawm lub hauv paus, thiab ntsuas qhov ntsuas kub raws li qhov yuav tsum tau ua ntawm cov lus qhia tshwj xeeb.

(3) Thaum lub sij hawm kho cov pob zeb kub-resistant, npog nws nrog yas zaj duab xis thiab straw hnab, thiab ua dej thiab kho raws li cov kev cai kom cov av noo.
