Abstract

The invention discloses a method for manufacturing a high strength steel sheet in a short process, the high strength steel sheet and application of the high strength steel sheet, and belongs to the field of metallurgy rolling and deep processing. The method comprises the steps that in the treating process of thin slab continuous casting and rolling, a thin slab which is subjected to finish rollingby a finishing mill group is obtained, and then the thin slab is directly cut into a preset size and is subjected to hot stamping processing after meeting the target temperature of hot stamping by induction heating to manufacture the high strength steel sheet. The method for manufacturing the high strength steel sheet in a short process realizes the integrated production from raw materials to products, saves the transportation cost of intermediate links, can achieve the purposes of energy saving, consumption reduction and green production, significantly shortens the overall manufacturing process of plate deep processing, and has the advantages of ultra-short process, deep processing and multi-variety small batch mass customization production.
