Continuous galvanizing of chains: FIB opens a new approach by Chaîneries Limousines

Among the European leaders in the manufacture of technical chains, Chaîneries Limousines have a highly recognized know-how.

Contrary to the consideration of a batch spinning galvanizing of chains, Chaîneries Limousines approached the matter with a semi-continuous process of galvanizing.

Considering the movement of the chain, the metallic kettle galvanizing furnace was designed by FIB Belgium accordingly, combined with a high energy efficiency approach. The combustion system may even accept blended natural gas with a concentration of 25% hydrogen, taking into account the vision of decarbonizing.

The experience showed that the finished products have a regular coating. FIB is also able to design ceramic galvanizing baths for which the use of high alloys such as 95% zinc / 5% aluminium or higher alloys may be processed.

In this framework, on top of the classical top heating system, FIB Belgium owns a specific heating system that is today the most energy efficient system that exists on the market by directly heating inside the molten zinc.
