Abstract
A roll system for a roller hearth furnace for thin slab casters is disclosed. The roll system includes a plurality of fluid cooled rolls rotatably mounted in the furnace configured to contact and at least partially support a charge transported along a pass line through the furnace. An upper surface of each of the fluid cooled rolls is positioned along the pass line. A plurality of dry rolls is rotatably positioned within the furnace wherein at least one dry roll is positioned between each pair of adjacent fluid rolls. The upper surface of each of the dry rolls is positioned below the pass line.
Claims11
A roll system for a roller hearth furnace comprising:
- a plurality of fluid cooled rolls rotatably mounted in said furnace configured to contact and at least partially support a charge transported along a pass line through said furnace, wherein an upper surface of each said fluid cooled roll is positioned on said pass line;
- and
- a plurality of dry rolls rotatably positioned within said furnace, wherein at least one dry roll is positioned between each pair of adjacent fluid cooled rolls, wherein an upper surface of each dry roll of said plurality of dry rolls is positioned below said pass line and wherein each said fluid cooled roll has a diameter greater than a diameter of each said dry roll.
A roll system for a roller hearth furnace comprising:
- a first set of water cooled rolls rotatably mounted in said furnace having an upper surface of each roll of said first set of rolls positioned along a pass line to contact and at least partially support a charge transported through said furnace;
- and
- a second set of dry rolls rotatably mounted in said furnace to contact the charge transported through said furnace, said second set of rolls interspersed between said first set of rolls, wherein an upper surface of each roll of said second set of rolls is positioned along a line positioned below said pass line and wherein a roll diameter of each roll of said first set of rolls is larger than a roll diameter of each roll of said second set of rolls.
A roll system for a roller hearth furnace for thin slab casters, said system comprising:
- a plurality of water cooled rolls rotatably mounted in said hearth furnace, an upper surface of each said water cooled roll positioned along a first plane defining a pass line through said hearth furnace, said plurality of water cooled rolls configured to contact and at least partially support a charge transported through said hearth furnace, wherein each said water cooled roll is of a first roll diameter;
- and
- a plurality of dry rolls rotatably mounted in said hearth furnace, an upper surface of each said dry roll positioned along a second plane positioned below said first plane and said pass line, each said dry roll is of a second roll diameter which is less than said first roll diameter, wherein a pair of said dry rolls is positioned between each pair of adjacent said water cooled rolls.
