A control method for a roller-type quenching process of a large-single-weight large-section super-thick steel plate. A specific heat model, a heat conduction coefficient model, a temperature field model and a correction model are involved in the method. The method specifically comprises: inputting steel plate parameters, technological regulations and actually measured parameters; sequentially computing an air cooling section, a water cooling section and a self-tempering section by using a temperature field model and invoking a specific heat model and the heat conduction coefficient model; and correcting the temperature fields by means of the correction model; and obtaining a simulation result, that is, obtaining a group of cooling curves and cooling rate curves at different thicknesses. The control method has the advantages: in combination with an actual production situation, cooling curves and cooling rate curves conforming to actual conditions are obtained; part of an actual debugging process can be substituted by model computing; the control method can be used for guiding the adjustment of the technological regulations and can reduce production costs; and products in a good plate shapes can be obtained.
