The invention discloses a method for producing a container plate by means of thin slab casting and rolling. The method comprises the procedures of converter smelting, LF refining, thin slab blank continuous casting, heating furnace heating and hot continuous rolling. In the LF refining procedure, tapped molten steel is controlled to be prepared from, by mass, 0.05% to 0.09% of C, 0.30% to 0.50% of Si, 0.40% to 0.60% of Mn, 0.070% to 0.120% of P, 0.001% to 0.015% of S, 0.30% to 0.50% of Cr, 0.03% to 0.10% of Ni, 0.25% to 0.40% of Cu and the balance Fe and inevitable impurities. By the adoption of the process, from the perspective of the whole-flow process, internal segregation of a continuously cast bloom is eliminated, the addition amount of alloy is reduced, whole-procedure energy consumption is reduced, the defect of a traditional process for producing the container plate is overcome, and the production process for producing the container plate with low cost is achieved.
