The company GALVAMÉTAUX, based in Europe, specializes in hot-dip centrifuge galvanizing of threaded steel or cast iron parts.
Previously equipped with top heating cover furnaces, the company sought, for its new furnace, a solution to reduce gas consumption and minimize zinc consumption. “Depending on each project, our engineering teams select the best solutions for general galvanizing and design a tailored bath,“ explains Erdinç Sezgin, Technical Director. The length, width, and depth of the bath vary depending on the size and weight of the parts to be galvanized.
“We chose the FIB GROUP, a well-known family company in Europe and worldwide, for this new furnace,“ says Éric Grégoire, Production Director at GALVAMÉTAUX SA. “What motivated us was the remarkable low energy consumption of the FIB furnace with immersed burners. At the same power, we can produce more.“
General galvanizing
Innovative in general galvanizing, the immersed burners are directly heating in the zinc. “The hot gases produced by the burner travel down the center of the tubes immersed in the zinc and rise toward the walls of it, transferring heat to the external tube material, which in turn transfers heat inside the molten zinc,“ explains Paul-Gaëtan Bareel, Commercial Director. “This technology allows up to 30% gas savings compared to top heating cover.“ Moreover, the FIB system enables easy cleaning of the drosses and ashes present in the bath, as the burners can be easily and fully removed. “Additionally, if a tube breaks, the burner can be stopped without stopping production.“
FIB GROUP has more than a hundred galvanizing furnaces installed worldwide. Their equipment can be developed with gas or electric heating solutions, depending on the demand. They are based on the same principle to directly heat inside the molten zinc. “We offer the alternative of electric immersed heaters, which allow our customers, as part of their environmental policy, to reduce their carbon footprint,“ concludes the Commercial Director. A key element to solve the challenge of the European ET5-2 constraints.
