A non-yielding low-carbon steel plate platform short process manufacturing method

The present invention belongs to the field of manufacturing steel C-Mn, in particular, it relates to a method for producing a non-short process yield low carbon steel platform. The first aspect of the present invention mass percent C? 0.002 ~ 0.010%, Si? 0.01 ~ 0.2%, Mn? 0.05 ~ 0.15%, S? 0.002 ~ 0.02%, P? 0.005 ~ 0.02%, sol-Al? 0.002 to 0.02%, the balance being Fe molten smelt low carbon steel, the molten steel through the tundish flows into the molten pool is formed, the molten steel bath surface to control the degree of superheat of 5 ~ 90 ℃, casting rollers after solidification and export, is formed lower steel Strips, at / s cooling rate of 10 ~ 80 ℃ the low carbon steel strip was cooled to 900 ~ 1200 ℃ hot rolling to obtain hot rolled strip, cooled to 500 ~ 780 ℃ coiling, unwound acid washing to remove oxide scale, to give no yield of low carbon steel plate platform. The present invention reduces the production cost, energy consumption and pollutant emissions, the method of the present invention for producing a low carbon steel plate after natural aging for more than 6 months still no tensile yield point occurs at room temperature.
