(3) Thaum lub rwb thaiv tsev castable tsim, tsim cov qauv yuav tsum ua kom tau raws li qhov yuav tsum tau ua, thiab kev teeb tsa ntawm tus qauv yuav tsum ua kom tau raws li cov lus qhia tshwj xeeb.
(4) Thaum lub castable rwb thaiv tsev yog ncaj qha mus rau lub rwb thaiv tsev masonry los yog lwm yam refractory masonry, ib tug cais tus neeg sawv cev yuav tsum tau teem rau ntawm masonry raws li tsim nyog.
4.Kuaj thiab tshuaj xyuas
Lub rwb thaiv tsev castable yuav tsum tau sim thiab sim ua ntej thiab thaum tsim kho:
(1) Ua ntej kev tsim kho, cov ntaub ntawv rwb thaiv tsev castable yuav tsum tau ua raws li kev tsim thiab kev koom tes, thiab ib qho kev sim ntsuas ntawm ib qho me me yuav tsum tau ua los ua qhov ntsuas kub ntawm qhov ntsuas kub thiab qhov ntsuas qhov ntom ntom. Tsuas yog tom qab kev tsim nyog siv tau;
(2) Nyob rau hauv kev tsim kho, cov castable rwb thaiv tsev yuav tsum tau muab raws li cov pa kev sim thaiv los ua ib txwm kub tsis kam thiab ntim ceev ntsuas.
5.cov khoom xyaw thiab nplawm
(1) Cov ntaub ntawv rwb thaiv tsev castable yuav tsum tau npaj raws li kev sib koom tes tsim. Kev ntsuas qhov yuam kev ntawm tus neeg sawv cev khi thiab tus neeg sawv cev sab nraud yog ± 2 feem pua, thiab kev ntsuas qhov yuam kev ntawm lub teeb sib sau yog ± 5 feem pua.
(2) Lub castable rwb thaiv tsev yuav tsum tau tov nrog pouring. Rau silicate cement converts, lub sij hawm tso kawm yuav tsum tsis pub tshaj 60 feeb; rau kev khi cov neeg ua haujlwm xws li alum av cement, iav dej, thiab phosphate, lub sijhawm tso kawm yuav tsum tsis pub tshaj 30 feeb.
(3) Lub rwb thaiv tsev castable yuav tsum tau nplawm nrog lub pob zeb sib tov, thiab lub sijhawm nplawm tsis pub tsawg tshaj 5 feeb. Ntxiv ib nrab ntawm cov dej thaum nplawm, ntub lub teeb sib sau, thiab tom qab ntawd ntxiv cov kab xev, hmoov, thiab ib nrab ntawm cov dej ntxiv kom txog thaum sib tov. Kev khiav hauj lwm qhov kev pab cuam rau cov neeg kho tshuab stirring yuav tsum ua tau raws li cov kev cai tsim.
(4) Thaum cov khoom sib xyaw ua ke, lub teeb sib xyaw yuav tsum sib xyaw ua ntej sib xyaw, ntub cov khoom ntim nrog dej, thiab tom qab 4H, cov khoom qhuav yog tov nrog cov khoom qhuav, thiab cov dej sib tov sib npaug.
(5) Lub rwb thaiv tsev castable yuav tsum tau nplawm kom txog thaum cov xim yog xim thiab cov tes yog pinched rau hauv ib lub pob, uas yog ib qho yooj yim rau daim ntawv.
6.Cov txheej txheem pouring ntawm thermal rwb thaiv tsev watering
(1) Lub castable rwb thaiv tsev yuav tsum tau nchuav txheej thiab hindered; Lub sij hawm vibration yuav tsum luv dua lub sij hawm vibration ntawm refractory pouring cov ntaub ntawv.
(2) Thaum lub rwb thaiv tsev castable yuav tsum tau muab nchuav rau ntawm lub refractory pouring, nws yuav tsum tau poured tom qab cov hluav taws kub-resistant pouring khoom yog khaws cia rau 24 teev. Thaum cov kua nplaum nyob rau hauv cov khoom siv refractory yog dej iav los yog phosphate, cov ntawv tsis muaj dej tsis zoo thiab cov yeeb yaj kiab yas yog siv los cais cov rwb thaiv tsev kub.
(3) Thaum nchuav cov rwb thaiv tsev kub thiab nchuav rau ntawm lub seam, qhov xoob ntawm qhov chaw yuav tsum tau ntxuav thiab ntub thiab ntub dej.
(4) Qhov saum npoo ntawm lub rwb thaiv tsev yuav tsum tiaj tus thiab ntom, thiab yuav tsum tsis muaj kab nrib pleb.
(5) Cov txheej txheem kev saib xyuas rau thermal castable rwb thaiv tsev yuav tsum tau txiav txim siab raws li cov nplaum sib txuas, thiab nws tuaj yeem khaws cia lossis tsis tas yuav khaws cia.
