Abstract：A unique method of dynamic and precise control of continuous hot dip galvanizing process parameters is summarized. Controlling of the height of the condensing line between 1 to 6 m, the optimum between 2 to 4 m, is the temperature control principle of the zinc pot. For the condensing line below 1 m, it should increase the zinc pot temperature,while for the condensing line above 6 m, it should decrease the zinc pot temperature. The method of correcting the temperature delay error and measuring error of the steel strip is to correct the reading of the optical pyrometer by the principle of heat balance. Based on the temperature of the zinc pot, the temperature control method for the steel entering the zinc pot is the control of the temperature difference between the zinc pot and the steel strip with different thicknesses. The thicker the steel strip is, the higher the temperature difference needs. This method conforms to the principle of hot- dip galvanizing production process, which is beneficial to ensure the production of good products and reduce energy consumption.
