The invention discloses a method for producing a 65Mn hot rolled steel plate, which comprises the steps of smelting, refining, thin slab casting, soaking, high pressure water descaling, hot continuous rolling, cooling and reeling based on the process of thin slab casting and rolling. The molten steel superheat temperature is T superheat (30 DEG C <T superheat </= 45 DEG C), the charging temperature of casting blanks is T charging (900 DEG C </= T charging </= 1050 DEG C), the final rolling temperature is T final (850 DEG C </= T final </= 950 DEG C), the reeling temperature is T reeling ( 550 DEG C </= T reeling </= 650 DEG C), the liquid core pressure of casting blanks is L pressure (2 </= L pressure </= 20mm), and the depth of a single-surface decarburized layer is 0.3 to 0.9 percent of the depth of the steel plate. The chemical constitutes of molten steel after being alloyed in a refining process comprise 0.62-0.70 wt.% of C, 0.17-0.37 wt.% of Si, 0.90-1.20 wt.% of Mn, less than or equal to 0.035 wt.% of P, less than or equal to 0.035 wt.% of S, less than or equal to 0.25 wt.% of Cr, less than or equal to 0.25 wt.% of Ni and the balance of Fe and inevitable impurities. The 65Mn hot rolled steel plate produced in the method has the characteristics of uniform structure property, high thermal stability and high strength, and the quality of the 65Mn hot-rolled steel plate is obviously improved.
