A continuous coating line includes a snout assembly exposed to molten metal. The snout assembly includes a snout tip positioned about a steel strip that is immersible in the molten metal to provide a seal around the steel strip during entry into the molten metal. The snout tip includes a refractory material that is resistant to wear, abrasion, and corrosion when the snout tip is exposed to the molten metal.

A weld wheel cleaning system is provided to clean or remove a layer of embedded material and other debris produced from welding from the working surface of a weld wheel. Such a weld wheel cleaning system includes a cleaner with an abrasive material positioned on an outer surface of the cleaner. The cleaner is positionable adjacent to the weld wheel such that the abrasive material is aligned with the working surface of the weld wheel. An actuator can be used to selectively actuate the cleaner with a force sufficient to remove the layer of embedded material from the working surface of the weld wheel with the abrasive material. The debris from the cleaner can be removed by a vacuum.

A steel processing line includes a dip tub and a stab roll. The dip tub is filled with a quantity of molten metal. At least a portion of the stab roll is submerged in the quantity of molten metal. The stab roll includes two journals. Each journal is received by an opening defined by a roller sleeve including a ceramic or refractory material. The roller sleeve is disposed between each journal and a bearing block. An inner dimension of each roller sleeve and an outer dimension of each respective journal defines a clearance. The inner dimension of each roller sleeve and the outer dimension of each respective journal is configured such that the clearance persists as the stab roll and the pair of roller sleeves are heated by the molten metal. Alternatively, inserts are fastened to an outer surface of each journal in lieu of the roller sleeves.

Method for extending the campaign life of stabilizers for a coating line

A steel processing line includes a roller submerged in a quantity of molten metal. The roller includes two journals. Each journal is received by an opening defined by a roller sleeve having a ceramic or refractory material. The roller sleeve is disposed between each journal and a bearing block to reduce or prevent wear on the journal. An inner dimension of each roller sleeve and an outer dimension of each respective journal defines a clearance. The inner dimension of each roller sleeve and the outer dimension of each respective journal is configured such that the clearance persists as the roller and the pair of roller sleeves are heated by the molten metal.

Method and apparatus for extending the campaign life of stabilizers for a coating line

A continuous coating line includes a roll assembly exposed to molten metal. The roll assembly includes a roll rotatable relative to a bearing block. The roll includes a roll portion and a journal protruding from each end of the roll portion. The roll is made from a refractory ceramic material that is resistant to wear, abrasion, and corrosion when the roll is exposed to the molten metal.
