Abstract

In this paper, the effects of Ti composition and rolling temperature on the surface iron oxide state, microstructure and mechanical properties of CH1T hot-rolled coils were investigated by taking φ6.5 mm CH1T coils as the object. The results show that the iron oxide of scheme one and scheme two rolled coils, with iron oxide thicknesses of 23 m and 17 m, respectively, has obvious bubbles on its surface. In contrast, the iron oxide of scheme three rolled coils, with its iron oxide thickness of 10 m, is smooth and evenly distributed. The grains of the rolled coils in scheme one is slightly mixed crystals, with a grain size level of about 6.5+5.0. Scheme two has a uniform distribution of grain size with a level of 7.5, and scheme three has a slightly finer near-surface grain compared to the matrix, with a level of 7.5+8.5. The tensile strength of the rolled coils in scheme one is about 30 MPa lower than that of the rolled coils in scheme two and scheme three, and there is no significant difference in the elongation after break.
