Cast Iron Protecting Tube

Cast iron tubes are available both coated and uncoated. Coated tubes have a thin ceramic coating which resists wetting of the tube by molten metals with the advantage of longer life in molten aluminum, zinc and lead.
It is recommended that uncoated tubes be dipped frequently in ladle wash or similar material to prolong life.
