File Synopsis:
Requiring the addition of a new multi-wire strand galvanizing line to meet growing market demand, Riverdale Mills made the goals of toxics use reduction a large part of the operational requirements of the new line. The company sought to reduce or eliminate the chemicals conventionally used in the process, the byproducts generated and the energy required. These goals required the innovative re-thinking of a mature industrial process. Riverdale Mills chose an induction heating chamber for the annealing process, eliminating the use of lead in the conventional liquid lead annealing process.
