Bell Less Top® – The Charging Solution
094519 08062015 (Folder) Bell Less Top - The Charging Solution
Bell Less Top® Charging Solution
Variability in raw materials, high coal injection rates, and reduced CO2 emissions can only be managed, by controlling burden distribution and segregation. More than ever, these factors emphasise the central role of the Bell Less Top charging system (BLT®) in blast furnace operations.
Since 1972, more than 700 units have been delivered worldwide.
Bell Less Top charging systems provide the fol-lowing benefi ts:
Safety is increased during maintenance work, no work inside the blast furnace.
Reduced operating expenses (OPEX).
Coke consumption savings achieved through increased pulverised coal injection levels, higher fl exibility in raw material usage and increased blast furnace top pressure.
Better blast furnace performance as a result of precise burden distribution.
A vital system to meet today’s blast furnace operation challenges
Smoother blast furnace operation with an add-ed benefi t of reduced variability of Si-content in the hot metal.
Control of wall heat losses from better charg-ing results in increased lifetime of cooling ele-ments or refractory lining, in turn leading to longer blast furnace campaign lifetime.
The Paul Wurth Bell Less Top is a reliable and proven technology.
Paul Wurth Bell Less Top Charging Systems are utilized in 60 % of global hot metal production.

Blast Furnace Plants
The Paul Wurth Bell Less Top Family, ideal for blast furnace volumes between 250 m3 and 6000 m3
Paul Wurth has created a complete Bell Less Top family providing charging systems for any blast furnace confi guration and size.
The Bell Less Top Family is complemented by Paul Wurth gearboxes and allows for easy retrofi t on bell top charging systems.
The gearbox line-up has been upgraded to include the new pressurised cooling (PC) system. The PC system provides higher cooling effi ciency, is maintenance free and is instrumental in the reduction of nitrogen consumption.
