Lub teeb yuag thiab cov khoom siv ua kom hnyav rau tundish npog tuaj yeem teeb tsa raws li cov neeg siv khoom. Lawv muaj cov yam ntxwv ntawm cov cua sov rwb thaiv tsev ua haujlwm, muaj zog, tsis muaj tev, tsis yooj yim rau deform thiab lub neej ntev kev pabcuam. Lawv tuaj yeem raug pov rau ntawm qhov chaw lossis preabricated raws li cov neeg siv khoom.
Lub thawv rau Molten Steel, suav nrog cov khoom siv tundish, lub rooj loog sab hauv, cov ntaub ntawv sab hauv, cov khoom siv sab saud, thiab cov ntaub ntawv sau ntxiv rau hauv tunding, thiab lwm yam khoom siv. Lubastable siv raws li cov ntaub ntawv hauv tedish yog feem ntau txhuas silicate cov khoom. Cov laj thawj rau kev puas tsuaj ntawm cov khoom siv no muaj raws li hauv qab no:
(1) kab nrib pleb thiab tev ntawm cov Castable;
(2) sintering nrog txheej txheej;
(3) kev puas tsuaj rau txoj kab slag;
(4) vau ntawm cov tundish phab ntsa, thiab lwm yam.
Hais txog kev sib tsoo ntawm lub phab ntsa pw, cov duab ntawm cov tundish thiab siv cov anchors thiab ingates tuaj yeem tiv thaiv nws los ntawm kev tshwm sim. Kev tiv thaiv ntawm tundish casible yog feem ntau ua tiav los ntawm kev siv txheej txheej, cov khoom siv quav ntawm cov khoom siv thiab cov khoom tawg thiab cov tawg thiab tev los ntawm thermal poob siab. Yog li ntawd, thaum txhim kho cov khoom ntawm cov khoom siv tundish, nws yog ib qho tseem ceeb kom txwv cov kev tawg thiab tev ntawm lubast thaum siv vim cov khoom muaj txiaj ntsig ntawm cov khoom.
