Abstract (en)
In order to manufacture a tin mill black plate, 0.01 to 0.12% of C, 0.005 to 0.5% of Si, 0.3 to 1.5% of Mn, 0.005 to 0.2% of P, 0.10% or less of Al, 0.012% or less of N, and 0.005 to 0.10% of Nb are contained, and solution hardening, precipitation hardening, and grain refining hardening are combined to obtain a black plate having a substantially ferrite single-phase microstructure having an average grain size of 7 µm or less and properties after baking after lacquering, such as a yield point strength of 500 MPa or more, a yield ratio of 0.9 or more, a total elongation of 10% or more, and ”r of -0.50 to 0. In particular, hot rolling conditions include FT of 870°C or higher, a cooling rate after hot rolling of 40 °C/s or less, and CT of 620°C or higher, and the average crystal grain size of a hot-rolled steel sheet used as a rolling raw material for the tin mill black plate is 6 µm or more.
