Furnace Roll
    • Summary:

      Vertical annealing furnace roller: used for continuous annealing line and galvanizing line of vertical annealing furnace. Under the nitrogen and hydrogen protection atmosphere and 750- 950 ℃in the furnace to do annealing of the strip steel.
      The diameter:600-1500mm
      The barrel: centrifugal casting
      Transition section: static casting
      Shaft: forging.
      Common material: Shaft (SUS304, 1Cr18Ni9Ti, etc.), barrel and shaft neck (ZG30Cr26Ni12, ZG40Cr25Ni20Si2, ZG14Ni32Cr20Nb, etc.).

    • Summary:

      Coating furnace roller:used for high-end car plates, home appliances plate continuous annealing line, vertical annealing furnace of galvanizing line. Under the nitrogen and hydrogen protection atmosphere, temperature at 750-950 degrees in the furnace, the strip steel is rapidly and uniformed annealed.
      Diameter:600-1500mm.
      The coating improved the hardness of the roller surface and is more stable during the operation process, greatly reduces the surface scratch and improves the plate qualit...

    • Summary:

      Horizontal annealing furnace roller: used for horizontal annealing furnace of continuous annealing and galvanizing lines. Under the nitrogen and hydrogen protection atmosphere, temperature at 750-950 ℃in the furnace,the strip steel is rapidly and uniformed annealed.
      Diameter: 100-500mmm.
      The barrel: centrifugal casting,
      Transition section: static casting
      Shaft: forging.
      Common material: Shaft (SUS304, 1Cr18Ni9Ti), barrel and shaft neck (ZG30Cr26Ni12, ZG40Cr25Ni20Si2).

    • Summary:

      Heavy plate heat treatment furnace roller: used on normalizing furnace and quenching furnace. Under the nitrogen and hydrogen protection atmosphere, temperature at 550-950 ℃in the furnace,the wide and heavy plate is rapidly and uniformed heat treated. Diameter: 300-400mmm.
      Barrel: centrifugal casting
      Transition section: static casting
      Shaft: forging.
      Common material: ZG14Ni32Cr20Nb, ZG45Ni48Cr28W5Si2, ZG40Cr25Ni20Si2.

    • Summary:

      Sink roll: used for galvanizing line zinc pot system. The galvanizing process will be carried out by continuous galvanizing through “three rollers & six arms”. The three rollers in the zinc pot are all passive rollers. The barrel is centrifugal casting, shaft is static casting. The main materials usually choose 317L, Cr22Ni4 and 316L;
      Common specification:500-800.
