| 摘 要： | 用原位统计分布分析仪(OPA-100)研究了拉速变化时(1.4 m/min 至0.6 m/min,0.6 m/min 至 1.4 m/min)IF钢1150 mm×230 mm铸坯表层试样夹杂物粒径和频数的分布。结果表明，夹杂物粒径与其频 数分布规律基本符合一阶指数衰减曲线，夹杂物粒径x(μm) 与频数 y 的拟合公式为 y = A1 ·exp (-x/tl)+y0; 式中A1,t1,y0为常数；R 为相关系数(R²>0.97)

| Abstract: | The distribution of size and frequency of inclusion in samples of surface layer of IF steel 1150 mm× 230 mm casting slab with unsteady casting speed(1.4 m/min to 0.6 m/min and 0.6 m/min to1.4 m/min)has been studied by Original Position Analysis System(OPA- 100). The results show that the distribution rule of size and frequency of inclusion basically accords with first-order exponential decay curves. The expressions of inclusion size x (μm) and frequency y is y=Al ·exp(-x/tl)+y0;A1,tl and yO are constant,R is related coefficient(R²> 0.97). |
