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
