Qhov nruab nrab ladle yog lub thawv khoom siv refractory siv hauv steelmaking thiab nruam casting. Nws thawj zaug tau txais cov hlau molten poured los ntawm lub ladle, thiab tom qab ntawd faib nws mus rau ntau yam crystallizers los ntawm nruab nrab ladle nozzle. Thaum hloov lub ladle nyob rau hauv multi furnace nruam casting, lub rub ceev tsis txo, tsim tej yam kev mob rau multi furnace nruam casting.
Castable cov ntaub ntawv rau metallurgical steelmaking tundish:
1. Permanent hauv ob sab phlu castable
Lub hauv paus ruaj khov ntawm cov pob nruab nrab feem ntau yog siv cov khoom siv aluminium silicon casting. Raws li qhov kev siv ntawm cov pob nruab nrab, cov khoom siv no yuav tsum muaj lub zog zoo, ntim ruaj khov, thiab thermal poob siab. Cov khoom siv refractory casting tsim rau nruab nrab ladle muaj lub neej kev pab cuam ntawm kwv yees li * * * rauv.
2. Ua hauj lwm hauv ob sab phlu qhuav
Cov khoom siv alkaline qhuav rau cov pob nruab nrab yog tsim los ntawm sintered magnesia xuab zeb, magnesia calcium xuab zeb los yog fused magnesia xuab zeb, magnesia calcium xuab zeb, nruab nrab kub kub sintering tus neeg saib xyuas, thiab ib tug me me ntawm kub-kub binder. Magnesium raws li qhuav ua hauj lwm hauv ob sab phlu muaj qhov zoo ntawm kev tsim kho yooj yim, siab ci thermal efficiency, yooj yim sib cais ntawm steel slag thiab nyob rau hauv ob sab phlu, ceev ceev turnover ntawm nruab nrab ladle, txhim kho steel zoo, thiab ntev kev pab cuam lub neej.
