New developments in bell-type annealing of wire and rod

For spheroidization and recristallization annealing of rod and drawn wire bell-type annealing plants are used. The article describes new design features of a modern bell-type annealing plant. Metallurgical results and the mechanical properties of the annealed wire rod with respect to spheroidization and decarburization are discussed. Finally experimental investigations of the decarburization of wire rod are explained.
