Bell Less Top® — G3 and PC Chute Transmission Gearboxes
How to be effi cient and reduce costs…40 years of know-how and experience in Bell Less Top charging technology have led to the develop-ment of the G3 Chute Transmission Gearbox providing a “worry-free” package…
… Sturdier
` Resists toughest operational conditions
` Designed for large-size blast furnaces
… Reduced maintenance costs
` Longer lifetime of chute tilting and planetary gear
` Maintenance-free cooling elements
… Higher process fl exibility
` 12 rpm rotation speed enabling more precise charging patterns
` Flow rates of up to 1.1 m3/s
Interchangeable with existing Chute Trans-mission Gears
Key features: ` New closed-loop, pressur-ised-water cooling system. No cooling water contact with blast furnace atmos-phere and grease, eliminating any cleaning requirements.
` Chute angle adjusting gear features enhanced continuous greasing with extended au-tonomy.
` Separated drive units with new seal system & back-up stuffi ng box.
` New combined bellow and spherical isolation valve.
` Closed body chute designed for centre coke charging.
` Condition monitoring system.

CTG-G3
With conventional chute transmission gearbox cooling, the water is in contact with the blast fur-nace atmosphere. Regular cleaning of the cooling elements is required to ensure cooling efficiency. To compensate for this loss of cooling efficiency, large volumes of nitrogen must be injected into the gearbox.
The newly designed Pressurized Cooling relies on S-CUP technology, which isolates cooling water from the blast furnace environment and thus avoids contamination. The S-CUP is contactless and prevents water overflow into the furnace.
Pressurized cooling
` is maintenance free,
` maximizes cooling capacity and leads to extend-ed equipment lifetime,
` lowers operational costs through reduction of water and nitrogen consumption.
Increased Process FlexibilityOperation of the distribution chute at 12 rpm (compared to 8 rpm) can achieve finer charging patterns. An increase in rotation speed also con-tributes to a reduction of impact energy of the material stream on the stockline surface of up to 40%.
This in-turn results in reduced deformation of lay-ers, coke-push and gouging effect. The benefits of this flexibility lead to a new standard in charging.

Continuous Greasing SystemThe Continuous Greasing System greases the chute tilting gears during chute tilting. The number of greasing points has been in-creased and the autonomy is at least 6 months.
With a combination of pressurized cooling and continuous greasing a longer chute tilting gear lifetime is achieved.
Technology spin-off: CTGWR-PCStriving continuously to fi nd the best solutions for our customers on a value/performance basis, we have adapted pressurized cooling and con-tinuous greasing for implementation in standard gearboxes.
Key features:
` Maintenance free cooling circuit (no trough cleaning or cooling panel pickling).
` Considerably reduced nitrogen and make-up water consumption.
` Longer chute tilting gear lifetime.

Upgrade Considerations ` The standard chute transmission gearbox can be substituted by either the PC series or the G3 gearbox
` During reconditioning, standard gearboxes can only be upgraded to PC series gearboxes
` While the G3 gearbox performance is supe-rior, the value of existing spare parts inventory should be considered.
Enter a new realm in blast furnace performance with the Paul Wurth G3 or the PC Chute Transmission Gearbox.
