Refractory tundish nozzles thiab stopper rods

Stopper rods: Ntawm tundish ntawm nruam casting tshuab, ib qho plugs yog dav siv. Lub inert shielding gas ejects los ntawm lub qhov me me nyob rau hauv lub taub hau ntawm lub plug pas nrig, uas yuav tiv thaiv tau cov txhuas oxide los ntawm depositing nyob ze ntawm lub sealing cheeb tsam ntawm qhov chaw nres nkoj dej, los yog txo nws aggregation npaum li cas, thiab txav mus rau hauv lub tsuj roj. Txhawm rau kom ntev lub neej ntawm lub taub hau ntsaws los pab txhawb ntau lub cub tawg tas li, ntsaws taub hau nrog zirconia multilayer lossis tag nrho zirconia plug rods yog siv rau ntawm tundish ntawm slab caster.
Tudish nozzles: Cov khoom ntawm tundish nozzles raug xaiv raws li hom hlau pouring, thaum pouring dav carbon steel, koj muaj peev xwm siv mullite nozzle uas muaj Al2O3 70 ~ 75%. Thaum pouring yooj yim-txiav steel, magnesium oxide los yog zirconia nozzles yuav siv tau. Thaum pouring siab manganese hlau, siab aluminium graphite los yog zirconia nozzles yuav siv tau.
