从冷却曲线上相变段倾角最小原则出发,研究了新型激冷剂的材料配比与热分析法检测铸铁成分精度的关系.实验结果表明,能使相变段倾角最小的成分配比,也能提高对铸铁成分的热分析检测精度.
Based on the principle of minimum inclination of phase transition in the cooling curve, the relationship between the material ratio of the new chilling agent and the accuracy of the thermal analysis of cast iron was studied. The experimental results show that the composition ratio of the phase transition with the smallest inclination is Can improve the composition of the cast iron thermal analysis detection accuracy.
