Correlations between coating components and deposited metal compositions of environmental protective type basic electrode

An electrode coating slag system CaO-CaF₂-BaO-TiO₂-SiO₂ has been designed after analyzing several domestic and abroad basic slag systems.The experiments were arranged with uniform design method and computer software.Nine to eleven coating components were taken as independent variables and they were divided into five levels in all twenty nine experiments.Five chemical elements contents in the deposited metal were taken as target functions and data were analyzed with mathematical statistic software.The results show the influencing trend figures of coating constituents on five chemical elements contents and interrelation multinomial mathematic models between independent variables and functions.With these trend figures and mathematic models,the adjusting direction of deposited metal chemical composition can be inquired and carry out target function optimization searching.
