Coke Oven Wear Solutions
Heat- and abrasion-resistant liners for coke handling.
Coke Oven
Zone Introduction
The Coke Oven plant produces metallurgical coke — the primary fuel and reducing agent for the Blast Furnace.
Continuous and smooth coke handling is critical because any flow interruption directly affects BF charging schedules and hot metal production.
This zone continuously handles hot, dense, sharp-edged coke lumps — creating a severe wear environment for chutes, screens, and conveyors.
How wear happens
Process Description
After carbonization, hot coke (~200–350°C) is pushed from ovens and transferred through guides, wharf, quenching systems, screens, and conveyors into storage or surge bunkers.
Coke handling involves:
Flow is nonstop during operations → structural plate thickness reduces rapidly.
Dust and heat together create wear that spreads faster than typical abrasion zones.
As screening and transfer systems choke, mechanical vibration increases → accelerating fatigue failure.
Even 12–20 mm thick plates become bent, holed, or cracked in short periods without engineered liners.
- Large dense lumps fall onto steel Strong impact loads
- Sharp coke edges rub surfaces Deep sliding abrasion
- Fine coke breeze High-velocity erosion & leakage
- Temperature shifts during quenching Thermal fatigue & cracking
- Coke dust is chemically reactive Corrosion-abrasion
Areas of Wear & Root Causes
- Coke screen underpans High-energy abrasion from sharp fines
- Transfer chute walls & lips Heavy impact gouging
- Bunker impact zones Large lump collision → plate deformation
- Belt loading points Frictional wear & dust erosion
- Discharge hoppers Constant flow → Groove formation
Performance Loss & Downtime Impact
- Choking & spillage Frequent shutdowns & labor cleanup
- Transfer leaks Dust exposure & unsafe environment
- Hot plate cracking Unplanned repair welding
- Uneven feeding BF operational instability
- Material loss Increased cost per ton of coke charged
Delayed BF feeding = direct production loss in steelmaking.
