OPTIMIZING ZINC CONSUMPTION IN HOT GALVANIZATION

摘要

For the ANGA-1700 continuous hot-galvanization unit at Ispat Karmet Joint Stock Company, on the basis of statistical methods, analytical formulas have been established for the zinc consumption in coating and in dross formation as a function of the technological parameters. These formulas permit regulation of the relevant parameters so as to minimize the zinc consumption in dross formation. Thanks to the use of these formulas, the zinc consumption in 2002 was 6.9 kg/ton less than in 2000, with increase in output by more than 40 percent.
