Method for Quickly Obtaining Setting Temperature of Walking Beam Billet Heating Furnace under Different Production Rates

Abstract

The invention discloses a method for quickly obtaining the setting temperature of a walking beam type billet heating furnace under different production rates, comprising the following steps: obtaining several sets of training data of a walking beam type billet heating furnace under different production rates, the training data includes Input data and output data; input data includes step cycle, billet heating accuracy and thermal uniformity degree of discharged billet; output data includes setting temperature with each control area; step B. train BP neural network, obtain i BP neural network models; Step C. Determine the step cycle corresponding to the target production rate, and adjust the thermal uniformity value of the discharged billet at the same time, so that the heating accuracy value of the billet is within the range of -5°C to 5°C; The degree value and billet heating accuracy value are used as the input data of the BP neural network model to obtain the setting temperature value of each control area corresponding to the target production rate. The invention has simple operation process, high heating precision, high energy utilization rate and low energy consumption.

Description

Technical field[0001]The present invention belongs to the technical field of stepper beam type slab heating furnace, and in particular, the method of rapid acquisition temperature is provided at different yields of step beam type billet heating furnace.Background technique[0002]In the prior art, there is no fast acquisition temperature to set the temperature at different yields of the step beam type slab heating furnace, and thus the temperature of the operating rate at different yields at different yields according to the experience is set, and thus the heating accuracy is low. Low energy utilization rate, large energy consumption. In the face of the urgent needs of the energy conservation and consumption reduction in the steel industry, there is an urgent need for a quick acquiring temperature to provide temperature at different yields of the stepped beam type slab, to increase the heating accuracy and energy utilization, and reduce energy consumption.Inventive content[0003]It is ...
