Kev tsim kho ntawm cov kub resistant castables yog nqa tawm los ntawm txoj kev vibration, uas yog siv dav, nrog rau kev tsim cov khoom siv vibration qhuav.Koj puas paub txoj kev siv kom raug ntawm qhov kub thiab txias castables?
1. Kev npaj ua ntej kev tsim kho
Raws li cov qauv tsim, kev tsim kho kom zoo ntawm cov txheej txheem dhau los yuav tsum tau kuaj xyuas thiab lees txais, thiab qhov chaw siv boiler yuav tsum tau ntxuav.
Kev quab yuam sib tov, plug-in vibrator, handcart thiab lwm yam tshuab thiab cov cuab yeej raug thauj mus rau qhov chaw siv boiler, ntsia rau hauv qhov chaw, thiab qhov kev sim khiav yog qhov qub.Cov lus hauv qab no qhia tau hais tias cov kev ntsuas kev ntsuas ntawm plug-in vibrator.Nws yuav tsum tau taw qhia tias qhov yuam kev vibrating pas nrig siv rau lub tov khoom yuav tsum muaj ntau zaus thiab yuav tsum muaj cov khoom seem txaus.
Lub formwork yuav tsum muaj lub zog txaus thiab rigidity, txawm tias nws raug thauj mus rau qhov chaw siv boiler;Lub teeb pom kev zoo txuas nrog, thiab cov dej huv yog txuas nrog rau pem hauv ntej ntawm lub tshuab tov khoom.
Kub resistant castables feem ntau yog ntim rau hauv hnab.Cov ntaub ntawv xws li thauj tog rau nkoj cib, txuas txuas, insulating refractory cib, calcium silicate boards, asbestos boards, refractory av nplaum cib thiab burner cib yuav tsum tau thauj mus rau lub boiler kev tsim kho qhov chaw txhua lub sij hawm raws li xav tau.
Thaum siv tshuaj binding tus neeg sawv cev, nws cov concentration lossis ntom yuav tsum tau kho ua ntej thiab thauj mus rau qhov chaw siv boiler rau kev siv.Ua ntej siv, nws yuav tsum tau stirred tusyees dua.
2. Kev txheeb xyuas ntawm kev tsim vaj tsev sib xyaw ua ke
Ua ntej kev tsim kho, lub hnab ntim kub resistant castables thiab lawv cov additives yuav tsum tau coj mus kuaj thiab kuaj raws li qhov yuav tsum tau ntawm tus tsim drawings los yog cov chaw tsim tshuaj paus cov lus qhia, thiab cov khoom tseem ceeb yuav tsum tau soj ntsuam.Thaum lub siab kub resistant castable ua tsis tau raws li qhov yuav tsum tau tsim, cov khoom yuav tsum tau hloov thaum ntxov li sai tau yam tsis muaj carelessness.Yog li ntawd, txoj haujlwm no tseem ceeb heev.Txij li thaum kev yuav khoom ntawm kub resistant castables, xim yuav tsum tau them rau lawv cov kev ua tau zoo ntsuas.Cov khoom tsim nyog yuav tsum tau siv los ua qhov sib xyaw ua ke ntawm qhov chaw siv boiler raws li cov xwm txheej ntawm qhov chaw siv boiler thiab lub sijhawm cia ntawm cov ntaub ntawv.
3. Tso thiab formwork ntawm thermal rwb thaiv tsev txheej
Rau kev vibration kev tsim kho ntawm kub resistant castables, cov hauj lwm no kuj belongs rau kev tsim kho.
Ua ntej kev tsim kho ntawm phab ntsa kub resistant castable furnace, firstly nteg asbestos board, calcium silicate board los yog refractory fiber xav, nruab hlau connectors, muab thauj tog rau nkoj bricks, thiab thib ob nteg insulating refractory bricks los yog ncuav lub teeb kub resistant castables;Qhov thib peb yog erect formwork.Qhov chaw ua hauj lwm ntawm lub formwork yuav tsum tau coated nrog roj los yog cov ntawv nplaum ua ntej, thiab tom qab ntawd ze rau qhov kawg ntawm lub ntsej muag ntawm lub thauj tog rau nkoj cib rau kev txhawb nqa.Qhov siab ntawm formwork erected txhua lub sij hawm yog 600 ~ 1000mm, thiaj li mus pab txhawb kev thauj khoom thiab kev co molding.Nyob rau hauv cov ntaub ntawv ntawm fetal membrane, lub fetal membrane yuav tsum xub txhawb nqa, thiab tom qab ntawd lub formwork yuav tsum tau tsim.Qhov saum npoo ntawm cov txheej txheej thermal rwb thaiv tsev yuav tsum tau muab tso rau hauv zaj duab xis yas los tiv thaiv nws los ntawm kev nqus dej thiab cuam tshuam rau kev ua haujlwm ntawm cov castable.
Thaum cov phab ntsa ntawm lub cub tawg siab, cov txheej rwb thaiv tsev yuav tsum tau ua nyob rau hauv cov khaubncaws sab nraud povtseg los tiv thaiv cov txheej txheej rwb thaiv tsev thaum lub pouring khoom vibrates.
Thaum lub sij hawm tsim kho ntawm refractory castable rauv sab saum toj, tag nrho cov formwork yuav tsum ruaj khov thiab ces oiled raws li qhov tsim dimension yuav tsum tau;Tom qab ntawd muab cov hlua khi rau ntawm lub lifting beam nrog cov hlau txuas.Qee qhov sib txuas yuav tsum tau kho nrog ntoo wedges, thaum lwm tus tsis tas yuav tsum tau kho.Cov hanging bricks yuav tsum tau muab tso rau vertically nrog lub qhov cub hauv ob sab phlu ua haujlwm.Qhov kev ncua deb ntawm lub ntsej muag hauv qab kawg thiab lub ntsej muag formwork yog 0 ~ 10mm, thiab lub ntsej muag kawg ntawm cov dai cib nrog ntau tshaj 60 feem pua cov ntsiab lus yuav tsum hu rau lub ntsej muag formwork.Thaum qhov sib nrug ntau dua 10mm, cov hlau txuas yuav tsum tau hloov kho kom tau raws li qhov yuav tsum tau ua.Nyob rau hauv cov ntaub ntawv ntawm lub qhov, lub membranes kuj yuav tsum tau ruaj khov, thiab tom qab ntawd cov formwork yuav tsum tau txhim tsa.
4. Sib tov
Kev sib tov yuav tsum tau siv rau kev sib tov.Thaum tus nqi ntawm cov khoom me me, nws kuj tuaj yeem sib xyaw manually.Qhov sib tov ntawm kub resistant castables yog txawv vim txawv ntau yam;Rau lub hnab ntim khoom lossis cov khoom sib sau ua ke thiab cov cement, qhov kev tso cai yuam kev yog ± 1.0 feem pua cov ntsiab lus, qhov kev tso cai yuam kev rau cov khoom ntxiv yog ± 0.5 feem pua cov ntsiab lus, qhov kev tso cai yuam kev rau hydrated kua binder yog ± 0.5 feem pua cov ntsiab lus, thiab ntau npaum li cas ntawm additives yuav tsum raug. ;Txhua yam ntawm cov khoom siv raw yuav tsum tau nchuav rau hauv lub tov khoom tom qab hnyav yam tsis muaj omission lossis ntxiv.
Rau kev sib xyaw ntawm cov kub kub resistant castables xws li cov cement, av nplaum sib txuas thiab cov cement qis, ua ntej ncuav lub hnab ntim khoom, cov khoom siv ntxiv thiab cov khoom ntxiv rau hauv cov khoom sib tov los tsim cov khoom siv ntau, thiab tom qab ntawd qhuav sib tov rau 1.0min, thiab tom qab ntawd ntxiv dej rau. ntub dej sib tov rau 3-5 feeb tom qab lawv sib xws.Tshem tawm lawv tom qab cov xim ntawm cov khoom sib xws.Tom qab ntawd nws raug thauj mus rau xibtes thiab daim ntaub pib.
Rau kev sib tov ntawm sodium silicate high-temperature resistant castable, cov ntaub ntawv raw los yog granules yuav muab tso rau hauv lub tov khoom rau qhuav mix, thiab ces cov sodium silicate tov yog ntxiv rau ntub mixing.Tom qab cov granules yog qhwv los ntawm sodium silicate, cov hmoov refractory thiab lwm yam ntaub ntawv ntxiv.Kev sib xyaw ntub dej yog li 5 feeb, thiab tom qab ntawd cov ntaub ntawv tuaj yeem tso tawm rau kev siv;Yog hais tias cov ntaub ntawv qhuav sib tov ua ke, ncuav lawv rau hauv lub tov khoom rau qhuav sib tov rau 1.0min, ntxiv 2/3 sodium silicate tov rau ntub sib tov rau 2-3min, thiab ntxiv cov seem binding neeg sawv cev rau ntub sib tov rau 2-3min, ces cov ntaub ntawv tuaj yeem siv tau.Kev sib xyaw ntawm resin thiab carbon uas muaj qhov kub thiab txias castable yog tib yam li qhov no.
Rau kev sib xyaw ntawm cov kub resistant castables xws li phosphoric acid thiab phosphate, thawj zaug ncuav cov khoom qhuav rau hauv lub tov khoom rau qhuav sib tov rau 1.0min, ntxiv txog 3/5 ntawm cov ntaub ntawv ntub dej sib tov rau 2-3 min, ces tso cov khoom siv. , thauj nws mus rau qhov chaw xaiv rau stacking, npog nws nruj nreem nrog yas zaj duab xis, thiab ntxiab cov khoom rau ntau tshaj 16h.Cov khoom ntim khoom thiab cov coagulant accelerator yuav tsum tau hnyav thiab nchuav rau hauv lub tov khoom rau kev sib xyaw ua ke, thiab cov khoom sib txuas ntxiv yuav tsum tau ntxiv rau kev sib xyaw ntub dej rau 2-4min ua ntej siv.
Thaum lub sij hawm sib tov ntawm kub resistant castables, yog hais tias additives xws li tshav kub-resistant steel fiber, hluav taws-resistant fiber thiab organic fiber yuav tsum tau ntxiv rau cov castables, lawv yuav tsum tsis tu ncua tawg mus rau hauv cov khoom sib tov ntawm tov khoom thaum ntub sib tov ntawm castables. .Lawv yuav tsum tau tawg thiab sib xyaw rau tib lub sijhawm, thiab yuav tsum tsis txhob muab tso rau hauv lub tov khoom hauv pawg.
Tom qab qhov sib tov tawm ntawm lub tshuab tov khoom, yog tias nws qhuav dhau, nyias dhau los yog tsis muaj qee yam khoom, cov khoom yuav tsum muab pov tseg thiab yuav tsum tsis txhob muab ntxiv;Qhov sib tov tawm ntawm lub tov khoom yuav tsum tsis pub dhau 0.5 ~ 1.0h.
