Steel Melt Shop (Scrap & Slag Zones)
Stronger protection. Zero interruptions.
Zone Introduction
SMS handles scrap charging, steel tapping, slag pouring — subjected to heavy impact + high heat.
Smooth scrap flow keeps heat cycle stable.
Breakdowns → Heat loss, inefficient operations, major yield drop.
Process Description
Scrap is dropped from a height into charging bins/chutes.
Slag flows from BOF/EAF during tapping.
Wear mechanisms:
- Scrap impact → denting & plate deformation
- Irregular sharp scrap edges → gouging
- Slag turbulence → chemical abrasion
- Repeated heating/cooling → metal fatigue & cracks
- Flame and radiant heat → accelerated wear
The more scrap recycled → Higher mechanical wear.
Slag zones are constantly attacked by corrosive compounds.

Areas of Wear & Root Causes
Charging chutes → Large impact forces
Scrap bins → Surface gouging
Slag channels → Hot abrasion + corrosion
Performance Loss & Downtime Impact
Charging delays → Longer heat cycle → Lower productivity
Runner wear → Slag leaks → Fire risk
High repair frequency → Excessive maintenance hours
