“…The surface temperature of the coil in scheme 3 is lower due to the further lowering of the spitting temperature, and as a result, the austenite grains do not have time to expand following recrystallization, resulting in a finer grain size. In addition [4][5][6][7][8] , the Ti(C,N) and Ti 4 C 2 S 2 precipitated phases increased with the decrease of temperature during rolling, and the increase of Ti content in scheme 2 and scheme 3 led to the increase of the number of precipitated phases, and the nailing effect of the precipitated phases led to the obstruction of austenite grain growth during the hot rolling process.…”

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 1 and scheme 2 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 3 rolled coils, with its iron oxide thickness of 10 m, is smooth and evenly distributed; the grains of the rolled coils in scheme 1 are slightly mixed crystals, with a grain size level of about 6.5+5.0; scheme 2 has a uniform distribution of grain size with a level of 7.5, and scheme 3 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 1 is about 30 MPa lower than that of the rolled coils in scheme 2 and scheme 3, and there is no significant difference in the elongation after break.
