Blast furnace bell-less top charging system
Burden charging and distribution equipment for blast furnace top systems.
- Chute rotation & tilt
- Material flow control
- Charging patterns
- Maintainable equipment
EQUIPMENT OVERVIEW
Built around
the operating duty.
A bell-less top brings together burden storage, gas sealing, pressure equalization and controlled distribution. Chute rotation and tilt work with material flow control to place the burden where the process requires it.
Material gates control burden movement. Sealing valves establish the gas boundary. These functions are coordinated with pressure equalization and the charging sequence.
