CORE PRODUCT
Polymer Composite Water Scraper
「 Heat-resistant · Highly wear-resistant · Non-absorbent · Balanced rigidity and toughness 」
PRODUCT OVERVIEW
Water Scrapers · Our Undisputed Core Business
Water scrapers are fitted on the entry and exit sides of the work rolls in every roughing and finishing stand (upper and lower plates). They look unassuming, yet they directly affect strip temperature and shape accuracy on a hot rolling line.
- Installation position: entry and exit sides of the work rolls in roughing and finishing stands (upper and lower plates)
- Core material: advanced polymer composite material — heat-resistant, wear-resistant and non-absorbent
- Mechanical properties: an excellent balance of rigidity and toughness; resists deformation and water-mist erosion at high temperature
- Service life: up to more than twice that of conventional products
- Supply mode: specifications customised to stand position, roll diameter and site conditions

THREE FUNCTIONS
Three functions of the water scraper
Water deflection
Block the cooling water, hold the rolling temperature
Cooling and spray water is guided away from the strip surface so the hot strip is not quenched too quickly, keeping the rolling temperature and metallurgical properties stable.
Temperature control
Close to the work roll, better cooling efficiency
The spray nozzles sit close to the work roll, creating turbulent spray in a confined space — lowering water pressure, improving cooling efficiency and controlling strip temperature drop precisely.
Surface protection in finishing
Less residual water, better strip shape
Reduces local temperature drops and surface defects caused by residual cooling water, helping to hold gauge and shape accuracy on the F7 exit strip.
PRODUCT RANGE
Product range
Subdivided by stand position and upper/lower location, covering water-blocking and scraping needs from roughing through finishing.
| Product name | Mill stand position | Primary function |
|---|---|---|
| Roughing entry upper scraper | Roughing stand, entry side · upper work roll | Blocks upper-roll cooling water, preventing the top surface of the strip from over-cooling |
| Roughing entry lower scraper | Roughing stand, entry side · lower work roll | Guides lower cooling water away, keeping the rolling temperature stable |
| Roughing exit upper scraper | Roughing stand, exit side · upper work roll | Water deflection, less residual water on the strip surface |
| Roughing exit lower scraper | Roughing stand, exit side · lower work roll | Collects and carries away lower return water |
| Finishing entry upper scraper | Finishing F1–F7, entry side · upper work roll | Creates turbulent spray close to the work roll for better cooling efficiency |
| Finishing entry lower scraper | Finishing F1–F7, entry side · lower work roll | Controls lower water volume for a stable temperature drop |
| Finishing exit upper scraper | Finishing F1–F7, exit side · upper work roll | Surface protection in finishing, fewer surface defects |
| Finishing exit lower scraper | Finishing F1–F7, exit side · lower work roll | Reduces local temperature drops from residual cooling water |
| Finishing Mill Side Dam Plate | Finishing stand, sideways | Controls sideways water-mist spray, improving the working environment and surface quality |
| Pinch roll entry / exit scrapers | Pinch roll stations | Water blocking and deflection for stable pinch-roll operation |

CUSTOMIZATION
Customisation and service process
STEP 01
Requirements discussion
We confirm stand position, roll diameter, upper/lower location, water temperature and strip specification.
STEP 02
Solution matching
Materials and structural solutions are matched to the application, with specification recommendations provided.
STEP 03
Sample approval
A sample is trial-produced to the confirmed plan, with dimensions and installation fit checked.
STEP 04
Batch production
Production runs to the confirmed process parameters, with batch testing to control consistency.
STEP 05
Delivery follow-up
Delivered on schedule with performance tracking to keep improving future deliveries.
