Pouring method and device capable of stabilizing the crystallizer molten steel surface temperature

The invention relates to a pouring procedure that can stabilize the temperature of molten steel surface in a crystallizer and a device thereof, which mainly solve the technical problems of high energy consumption and potential safety hazard that exist in the existing method for stabilizing the temperature or superheat degree of molten steel in the crystallizer. The pouring procedure that can stabilize the temperature of the molten steel surface in the crystallizer comprises the following steps: a. signals of molten steel temperature obtained by one or more of three devices of a pouring box molten steel temperature continuous measuring device, a crystallizer molten steel surface temperature continuous measuring device and a crystallizer copperplate temperature measuring device are transmitted into a first-level computer system; b. when the temperature of the molten steel deviates from the target temperature, the first-level computer system controls the crystallizer for electromagnetic braking or stirring, ther
