CCM – Continuous Casting Machine
Stronger protection. Zero interruptions.
Zone Introduction
CCM defines surface quality of final product.
Hot scale & water spray cause severe corrosion–abrasion.
Critical flow paths must maintain geometry.
Process Description
Steel strand exits mold → still very hot → scale detaches.
Scale slides and impacts guides, rolls and chutes.
Wear behavior:
- Hard scale flakes → Abrasive cutting
- Water slurry → Corrosion + Erosion
- Strand misalignment → Localized friction wear
- Tight clearances → Contact grooving
Continuous casting campaigns accelerate wear drastically.
| Application | Problem Observed | Artha Expertise / Solution |
|---|---|---|
| Tundish lining area | Severe thermal shock and erosion from molten steel | High chromium Carbide high-temperature resistant wear liners |
| Tundish impact zone | Heavy impact from molten steel stream | High chromium Carbide wear-resistant liners for extended service life |
| Tundish furniture (dams, weirs) | Erosion due to molten metal flow | High chromium Carbide wear plates with high thermal stability |
| Mold area | Intense heat and metal adhesion | High chromium Carbide liners to resist heat and wear |
| Strand guide rollers | Continuous abrasion and thermal cycling | High chromium Carbide wear-resistant coatings and liners |
| Secondary cooling zone | Water, scale, and thermal shock damage | High chromium Carbide liners with high thermal fatigue resistance |
| Segment frames & support structures | Mechanical wear and vibration | High chromium Carbide wear plates for extended service life |
| Torch cutting area | Intense heat and molten splash | High chromium Carbide heat-resistant liners |
| Slab discharge zone | Impact and abrasion during slab movement | High chromium Carbide liners for impact resistance |
| Scale pits & drainage channels | Erosion due to scale and high-velocity water | High chromium Carbide wear plates for long-lasting protection |
| Roller tables | Continuous contact with hot slabs | High chromium Carbide wear-resistant liners for extended life |
| Dummy bar handling area | High mechanical stress and wear | High chromium Carbide wear plates for heavy-duty applications |
Areas of Wear & Root Causes
Mold exit guides
Secondary cooling troughs
Roll supports near nips
Performance Loss & Downtime Impact
Surface defects → Coil/Billet rejection
Higher breakout risk
Maintenance delays casting sequence
