Method for recording temperature curve in heavy rail steel billet heating process

Abstract

The invention provides a method for recording a temperature curve in a heavy rail steel billet heating process, which comprises the following steps: acquiring and storing temperatures of a preheating section, a first heating section, a second heating section and a soaking section of a heating furnace in real time; compiling steel billet tracking numbers for heavy rail steel billets before the heavy rail steel billets enter the heating furnace; after the heavy rail steel billets enter the heating furnace, respectively tracking and storing the preheating section entry time, the first heating section entry time, the second heating section entry time and the soaking section entry time and the discharging time in real time; respectively calculating the holding time of the corresponding heavy rail steel billets at the preheating section, the first heating section, the second heating section and the soaking section; extracting real-time temperature data of each steel billet track number at the preheating section, the first heating section, the second heating section and the soaking section; and drawing and storing a temperature curve in the heating process of each section according to the real-time temperature data of the holding time at each section. In the method, the real-time temperature of the heavy rail steel billets at each section of the heating furnace is converted into the temperature curve of the heating process at each section, thereby facilitating analyzing the temperature distribution of the heavy rail steel billets in the furnace. The invention is also applicable to coal gas flow and pressure alarming.

Description

technical field [0001] The invention relates to computer real-time data acquisition technology, in particular to a method for recording real-time heating temperature curves during steel billet heating. Background technique [0002] The necessary process of the heavy rail rolling mill production line is to first heat the heavy rail billet, the purpose of which is to reduce the deformation resistance caused by the pressure processing in the rolling process. [0003] In order to improve the heating quality of the heavy rail billet, it is necessary to master the rules of the heating process of the heavy rail billet in each section of the heating furnace, so as to ensure the temperature value of the heavy rail billet when it comes out of the furnace. Therefore, it is necessary to study the temperature of the heavy rail billet in the heating process of each section of the heating furnace curve. [0004] The temperature measurement method of the existing heating furnace is: rely o...
