The invention relates to a method for confirming decarbonization process parameters of a steel rolling heating furnace. The method comprises the following steps: taking decarbonization process data obtained through decarbonization with different steel rolling heating furnace decarbonization process parameters as a sample, inputting the decarbonization process data into a neural network model for neural network model training; taking measurement data and furnace data monitored by a heating furnace monitoring system as an input value, inputting into an input layer of the trained neural network model; and simulating decarbonization layer thicknesses under different production working conditions by continuously adjusting values of the measurement data and the furnace data. When the decarbonization layer thickness is less than 0.5% of an error D between practical decarbonization layer thickness data AY and theoretical decarbonization layer thickness data CY, the values corresponding to themeasurement data and the
