Production method of AH36 structural steel plate for strip plate

The invention discloses a production method of an AH36 structural steel plate for a strip plate. The production method comprises the process steps of molten iron pretreatment, converter treatment, refining, continuous casting, plate blank heating, rolling, hot straightening, finishing, stack cooling and performance inspection. The steel comprises the following chemical components in percentage by mass: 0.15 to 0.18 percent of C, 0.20 to 0.40 percent of Si, 1.40 to 1.55 percent of Mn, less than or equal to 0.020 percent of P, less than or equal to 0.005 percent of S, 0.020 to 0.050 percent of Als, less than or equal to 0.020 percent of Nb and the balance of Fe and inevitable impurities. Through reasonable component design and a rolling process, the produced steel plate is stable in mechanical property, the sidewise bending deviation value of the steel plate is basically controlled within 5 mm after the steel plate is subjected to flame cutting and splitting in the rolling direction, and the use requirement of
