Hot Strip Mill
Stronger protection. Zero interruptions.
Zone Introduction
Hot strip with heavy scale → Harsh corrosion–abrasion mix.
Guides protect strip quality → Any wear affects the product.
Process Description
Reheated slabs form scale → Broken by descaling → Carried into mill.
Wear mechanisms:
- Scale trapped under strip → Grinding effect
- Water + scale → Corrosive slurry
- Strip tension → Edge friction
- Repeated thermal cycling → Plate cracking
This damages both equipment and product finish.
| Application | Problem Observed | Artha Expertise / Solution |
|---|---|---|
| Reheating furnace skid rails | Severe abrasion and thermal fatigue due to high temperature slabs | High chromium Carbide wear-resistant plates with high-temperature resistance |
| Charging & discharging tables | Continuous impact and surface wear from hot slabs | High chromium Carbide wear liners for long service life |
| Roughing mill entry & exit tables | Heavy abrasion and mechanical impact | High-strength High chromium Carbide liners for extended durability |
| Finishing mill roller tables | Continuous wear due to scale and hot metal | High chromium Carbide wear plates for superior abrasion resistance |
| Descaling headers & chutes | Erosion caused by high-pressure water and scale | High chromium Carbide plates resistant to erosion and abrasion |
| Run-out table (ROT) | Thermal cycling and mechanical wear | High-temperature High chromium Carbide liners for long-term performance |
| Coil box / down coiler area | High stress and thermal shock | High chromium Carbide wear plates with superior heat resistance |
| Transfer chutes & guides | Impact and abrasion from strip movement | High chromium Carbide liners for extended life and reduced downtime |
| Scale pits & collection systems | Severe abrasion from scale accumulation | High chromium Carbide wear liners for improved wear life |
| Mill side guards & covers | Constant wear and vibration | High chromium Carbide plates to enhance durability and safety |
| Exit roller tables | High-speed rolling contact and abrasion | High chromium Carbide wear liners for longer operational life |
