【摘要】 采用ZWZY5配方设计系统拟订试验方案，对试验数据进行直观分析、正交回归、最优化计算，建立了堆焊金属硬度的回归方程，找出了各药皮成分对堆焊金属硬度、抗裂性、工艺性能等的影响规律，研制成功了综合性能优良的EDC68超高硬度、超高耐磨、高韧性、耐冲击堆焊电焊条。更多还原

【Abstract】 Adopting ZWZY5 system for prescription design, the authors drew up a test plan, conducted the computation by the means of plain understanding analyses, orthogonal reagression and optindzation, and established the regression equations of the deposit metal hardness. As a result, the influential laws of each coating constituent to the deposit metal hardness, crack - resisting property and technology property, ect. have been obtained, In the end, the deposit electrod-EDC68 has been successfully developed. It has fine comprehensive properties such as super high hardness and wearability, high toughness and resistive impact - resisting.更多还原
