Roll & Equipment

KRST is Korea's sole specialized manufacturer of custom rolls and equipment.

Disk Brush Roll

The Disk Type Brush Roll is designed for de-scaling, de-greasing, and cleaning of strip surfaces in industries such as steel and non-ferrous metals. Our company produces custom brush rolls to meet the specific needs of customers, utilizing directly extruded bristles for various applications, from ultra-thin foils to steel descaling.

Disk Type

A method of brush manufacturing in which holes are punched into the curved surface of a disk-shaped steel plate, and brush filaments are inserted. These disk plates are then stacked to form the brush roll.

Disk Type Features

The disk layering method enables the creation of Brush Rolls with customizable densities. High-density Brush Rolls can maintain internal pressure for extended periods, making them suitable for demanding brushing tasks.

  • Consistent Quality: Brushes with minimal gaps can be produced, supporting high-density operations. The ability to maintain elevated layering pressure over time is ideal for intensive tasks.
  • Hair Loss Mitigation: Filament implantation in each perforation prevents continuous hair loss, with the option for partial repairs by replacing the disk.
  • Implantation Methods: Three filament implantation methods are available, allowing flexibility to meet specific quality and cost needs.

Brush Filament Type

  • C - Type: Cleaning Brush
    • Specifically designed for soft wiping of strip surfaces, this brush is used for normal rinsing and degreasing applications.
    • Commonly used in Final Rinse Zones, such as STS APF, CAL, and EGL
  • M - Type: Middle Abrasive Brush
    • Ideal for removing scale from strip surfaces and improving pickling efficiency.
    • CGL (Alkali & Abrasive Brush)
  • H - Type: Heavy Abrasive Brush
    • Primarily used for scale removal from strip surfaces and improving pickling performance.
    • Offers superior grinding ability compared to the M-Type.
    • CGL (Abrasive Brush), HCGL, and STS_APF
  • D - Type: Descaling Brush
    • Typically used in STS Pickling Sections, this brush excels at scale removal and offers superior pickling capabilities.
    • STS_PICKLING SECTION BRUSH
  • F - Type: Fine Polishing Brush

    • CGL and CAL

Disk Cassette Brush Roll

Designed in the format of a DISK TYPE BRUSH, this product is not pre-stacked on a roll shaft. Instead, it is supplied as modular blocks of specific lengths tailored to the required dimensions. End users can easily assemble these blocks onto the roll shaft for efficient operation.

As depicted in the image, the implementation of an expansion key ensures secure fixation of the cassette, effectively eliminating any clearance between the shaft and the cassette. This design prevents chattering marks and mitigates the risk of shaft damage during roll operation.
