High-copper hot rolled steel as well as preparation method and application thereof

The invention provides high-copper hot rolled steel as well as a preparation method and application thereof. The high-copper hot rolled steel comprises the following chemical components (wt%): 0.045 wt% < = C < = 0.070 wt%, 0.100 wt% < = Si < = 0.150 wt%, 0.250 wt% < = Mn < = 0.350 wt%, less than or equal to 0.018 wt% of P, less than or equal to 0.008 wt% of S, 0.025 wt% < = Al < = 0.070 wt%, 0.015 wt% < = Ti < = 0.030 wt%, less than or equal to 0.004 wt% of N, 1.50 wt% < = Cu < = 2.00 wt%, 0.001 wt% < = B < = 0.002 wt% and the like. The surface quality and the mechanical property of the high-copper hot rolled steel can meet the requirements of cold rolling and food steel and the processing requirements of a coating-free non-stick pan, and the high-copper hot rolled steel has good non-toxic, corrosion-resistant and antibacterial properties and wide application prospects. And the preparation process is simple and low in cost. 本发明提供了一种高铜热轧钢、制备方法及其应用，该高铜热轧钢的化学组成(wt％)为0.045wt％≤C≤0.070wt％、0.100wt％≤Si≤0.150wt％、0.25
