不锈钢焊条的混料回归分析与优化设计

针对焊条配方设计时受总量为 1 0 0 %和各因素都有不同的上下限约束这两个特殊条件制约的情况 ,以焊条配方的计算机辅助设计为手段 ,采用混料回归分析法 ,找到了不锈钢焊条的综合性能指标与焊条各组分之间的回归方程。用二次曲面的主轴梯度法优化目标函数 ,得到了电弧稳定、飞溅小、脱渣性好且焊缝金属含硅量符合国家标准规定的不锈钢焊条的配方

The mixture regression and optimization design of the stainless steel coating formula

In accordance with the constraints of total content 100% and the minimum and maximum content of every coating factor in the stainless steel covered electrods, the regression equation of the five elements' quadratic surface is established Used the gradient method of the quadratic surface, a better coating formula of stainless steel covered electrods is founded with the optimization of the objective function Welding experiments prove that the new coating electrods have better arc stability and detachability, Si content of weld metal is 0 67% which is up to the GB983-85
