Heating furnace plate blank charging temperature calculation method

Abstract

The invention discloses a method for calculating the charging temperature of a plate blank of a heating furnace. Firstly, according to the continuous casting initial temperature and the continuous casting cutting time of each point in the thickness direction of a plate blank, the plate blank temperature of each plate blank reaching a hot rolling conveying roller way is calculated; calculating the plate blank temperature when each plate blank leaves the hot rolling conveying roller way according to the conveying time; secondly, based on different destinations after each plate blank leaves the hot rolling conveying roller way; and finally, the temperatures of the upper surface and the lower surface of the plate blank are measured through a thermodetector arranged before the plate blank enters the furnace, and then the furnace entering temperature of the plate blank is determined by comparing the measured values of the temperatures of the upper surface and the lower surface with the calculated values of the temperatures of the upper surface and the lower surface. According to the method for calculating the charging temperature of the plate blank of the heating furnace, from continuous casting of the plate blank, accurate tracking of the temperature is formed based on different paths and time before the plate blank is charged into the furnace, the charging temperature is corrected in combination with set temperature detection of the upper surface and the lower surface, and more accurate charging temperature determination is formed.
