This component is used in the following industrial products
A steel ladle with an interior refractory lining designed to withstand high temperatures and contain molten metal during transfer operations.
The primary containment vessel where molten metal and desulfurizing agents interact to remove sulfur impurities.
The main reaction vessel in a Basic Oxygen Furnace (BOF) where molten iron is converted into steel through oxygen blowing.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
2 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
The steel shell provides structural integrity, contains the refractory lining, supports mechanical loads (including molten metal weight), and offers attachment points for handling equipment like trunnions and tilting mechanisms.
ASTM A516 steel offers good weldability, toughness at elevated temperatures, and resistance to thermal fatigue—critical for withstanding repeated heating/cooling cycles in molten metal applications.
Design features include expansion joints, stiffening rings, and controlled thickness transitions to accommodate differential thermal expansion between the hot refractory lining and cooler outer shell.
