Example Embodiment
[0065] Example 1
[0066] The manufacturing process is as follows:
[0067] TDS hot metal deep desulfurization → converter smelting → LF → RH (feeding Si-Ca wire) → continuous casting (using light reduction process) → slab off-line finishing → slab cut to length → heating → TMCP → slow cooling →AUT / MUT (automatic / manual flaw detection)→Steel plate trimming, cutting head and tail→Sampling and performance test→Cutting steel plate to length→Surface quality and appearance size, marking and testing→Delivery.
[0068] See Table 1 for the chemical composition of the embodiment, Table 2 and Table 3 for the manufacturing process, and Table 4 for the properties of the steel plate.
