1, Khoom piav qhia:
Cov khoom siv phom tundish ua los ntawm magnesia xuab zeb thiab olivine xuab zeb ntxiv rau ntau yam additives muaj kev ua tau zoo dua. Nws yog ib qho cua sov hardening lossis roj hardening refractory nrog muaj zog adhesion. Nws tuaj yeem tau txais cov txheej sib tw tuab nrog kev ntom ntom ntom ntom ntom ntom, cov nyhuv txwv tsawg kawg nkaus.
Cov khoom siv phom tundish tsim los ntawm peb lub tuam txhab muaj cov yam ntxwv hauv qab no
1) Nws tuaj yeem tiv taus qhov thermal stress generated hauv tundish system
2) qhov hloov pauv hloov pauv tau zoo thiab muaj kev ua haujlwm zoo ntawm tus kheej,
3) lub hauv ob sab phlu lub cev nto yog du thiab conducive rau lub stripping ntawm txheej ua hauj lwm
4) nws muaj zog corrosion kuj
5) kev ua vaj tse ntawm tundish hauv ob sab phlu tuaj yeem txhim kho lub neej kev pab cuam ntawm tundish

3, Kev tsim kho txoj kev: tshuaj tsuag qhov sib tov mus rau qhov chaw phom nrog rab phom tsuag
4, Nta
1) Cov ntaub ntawv sib tov ua slurry tom qab ntxiv dej, uas yooj yim rau tshuaj tsuag rau ntawm qhov chaw phom
2) Kev tsim kho yog yooj yim thiab yooj yim
3) Muaj zog adhesion thiab qis rebound tus nqi
4) Corrosion kuj, muaj zog slag corrosion muaj peev xwm thiab zoo daim ntawv thov
5) Kub siab flexural zog thiab kub tsis tshua muaj kab hloov pauv tus nqi
6) Muaj zog compactness
5, Daim ntawv thov: tundish gunning
6, Cia: cov khoom tau ntim rau hauv lub hnab tsis muaj dej. Nws yog nruj me ntsis txwv tsis pub kom ntub dej nag thiab daus. Cov khoom tau muab khaws cia rau hauv lub tsev khaws khoom noo noo thiab cua tshuab rau 3-6 hli. Yog tias cov khoom raug pom tias yog khoom qab zib vim muaj dej noo, lawv tsis kam siv.
7, Cov lus pom zoo ntawm cov khoom siv tau zoo, cov khoom tau raug xa tawm mus rau Kaus Lim Qab Teb, Nyiv, Pakistan
8, Peb yog cov kws tshaj lij kev lag luam, uas tuaj yeem muab cov neeg siv khoom siv khoom siv dawb, siv thiab lwm yam teeb meem
