(1) Tag nrho lub hnab ntawm cov ntaub ntawv refractory yuav tsum tau siv, tsis yog cov ntaub ntawv uas tau qhib, puas thiab raug dej.
(2) Cov khoom tsim los ntawm ob lub tuam txhab sib txawv yuav tsum tsis txhob sib xyaw, thiab yuav tsum tsis txhob muab ob qho khoom sib txawv.
(3) Tsis muaj cov khoom ntxiv xws li cov cement, limestone, lossis lwm yam khoom siv ntxiv (tshwj tsis yog steel fibers) tuaj yeem ntxiv rau cov khoom tshwj tsis yog cov chaw tsim khoom pom zoo.
(4) Cov khoom siv hluav taws xob nrog cov pob lossis cov dej ntws hauv lub hnab tsis tuaj yeem siv. Thaum lub sij hawm kev thauj mus los thiab khaws cia ntawm refractories, lawv yuav tau compacted rau hauv lumps; cov pob no yuav maj mam rub tawm ntawm tes thiab yuav tsis cuam tshuam rau kev ua haujlwm ntawm refractory.
(5) Kev sib xyaw, kev xa tawm, thiab kev teeb tsa cov ntaub ntawv yuav tsum ua raws li cov chaw tsim khoom pom zoo kom sib xyaw qhov kub thiab txias rau cov khoom siv tshwj xeeb. Kev sib xyaw kom zoo kub yuav ua kom lub cev muaj zog ntawm cov castables.
(6) Lub installer yuav tsum tsim kom muaj qhov ntsuas kub uas tsim nyog rau kev sib xyaw kom zoo.
(7) Yog tias tsis tau teev tseg los ntawm cov chaw tsim khoom, lub sijhawm sib xyaw tag nrho los ntawm kev ntxiv dej yuav tsum tsis pub tsawg dua 3 feeb thiab tsis pub tshaj 5 feeb. Rau qhov tsawg, ultra-low, thiab tsis muaj binder refractories, lub sij hawm sib tov yog qhov tseem ceeb hauv kev txiav txim siab qhov kawg ntawm lub cev ntawm cov khoom.
(8) Tus nqi ntawm cov khoom siv refractory yuav tsum sib xyaw ntawm txhua qhov sib xyaw yog teem raws li kev ua haujlwm thiab yuav tsum tsis txhob loj dhau ib zaug los xyuas kom meej tias cov khoom sib xyaw raug teeb tsa ua ntej molding.
(9) Cov khoom siv refractory yuav tsum raug xa mus rau qhov chaw teeb tsa sai li sai tau thaum nws tawm ntawm lub tshuab tov khoom. Lub sij hawm luv ntawm kev sib xyaw, dej ntxiv, kev xa khoom, thiab kev tsim kho cov khoom siv refractory yuav tsum ua raws li cov khoom tsim khoom tshwj xeeb.
(10) Kev ntsuas yuav tsum raug coj los tiv thaiv kev sib cais ntawm cov khoom thaum lub sij hawm xa cov khoom sib tov.
