Continuous furnaces

Whether it’s annealing and galvanizing lines or a roller hearth furnace, electric heating can make the process cleaner and more efficient, while greatly reducing maintenance and repairs.

The benefits of electric heating over gas in roller hearth furnaces

With furnaces operating 24 hours a day, having a stable process is crucial to the quality of the end product. With Kanthal Tubothal® metallic heating elements and a range of solutions for roller hearth furnaces, the power output is on par with gas and virtually all ofthe heat produced is being used inside of the furnace.
