An electrode coating slag system CaO-CaF2-BaO-TiO2-SiO2 has been designed after analyzing several domestic and abroad basic slag system. In view of uniform design method and computer program, the experiments were arranged. Nine to eleven coating components were taken as independent variables and they were divided into five levels in all twenty-nine experiments. Four mechanical properties and diffusible hydrogen content of weld deposited metal were taken as target functions. The data were analyzed with mathematical and statistic software. The results give the influencing trend figures of coating components on mechanical properties and diffusible hydrogen content and interrelation multinomial mathematic models between independent variables and functions. With these trend figures and mathematic models, the adjusting direction of improving mechanical properties and decreasing diffusible hydrogen content of weld deposited metal can be inquired, and target functions optimization searching have been done.
