الملخص

This paper deals with the concept of quality engineering and robust design as one of the new practical  methods for the improvement of galvanizing parameters design in order to obtain the best mechanical  properties (hardness) by experimental design and robust design tools. By using Taguchi parameter  design, three factors (controllable factors) were chosen, which are temperature, time, and withdraw  speed, along with three levels for each factor to determine their effect on the hardness in galvanizing  steel in order to obtain better quality levels. A L27(33) orthogonal array was selected and used in this experiment. 

Minitab  software  was  used  in  design  and  data  analysis  to  achieve  the  desired  quality  objectives.  Results show that the best combination to achieve a desired hardness were (T=455 ˚C, t=4 min., and  S=6 m/min ). The experiment also revealed that the temperature and time have the largest effect on the  hardness. In addition, the optimum condition was verified during the optimization stage using central  composite design.
