The non wetting castable is good for maintenance and cleaning purpose, it is usually apply at the molten contact area such as hearth, lower sidewall, ramp and transfer launder area.
But this non wetting effect will gone when it operate under more than 1000 deg C for few hours.
NON WETTING - Special castable for aluminium containment applications only
