Embodiment Construction

[0064] In order to facilitate the understanding and implementation of the present invention by those of ordinary skill in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] like figure 1 Shown is the heat balance block diagram of the steel rolling industrial furnace. The supply heat of the steel rolling industrial furnace is mainly the chemical exotherm generated by the combustion of fuel, and the effective heat is the physical heat taken away by the heated billet, and the heat taken away by the flue gas and the loss of the furnace wall is the heat. loss, from figure 1 It can be seen that there is an energy balance relationship among the three.

[0066] That is: the effective heat entering the industrial furnace = the effective heat taken away by the billet + the lost heat

[0067] figure 2 It is the flow chart of dynamic thermal balance test and calculation.

Abstract

The invention relates to a method for testing the dynamic thermal balance of a steel rolling industrial furnace. In the method, a dynamic thermal balance testing technology is adopted, namely the running state of the industrial furnace under various conditions is subjected to continuous monitoring and data acquisition, the dynamic thermal balance state of the industrial furnace is obtained through special data processing technology and algorithm, the normal production of the industrial furnace is not influenced, the data processing is completed instantly, the efficiency for the thermal balance test can be greatly improved, and continuous thermal balance testing data can be acquired simultaneously. Therefore, the method has more comprehensive instructive significance for the energy conservation and consumption reduction work of the industrial furnace.

Description

technical field [0001] The invention relates to a method for testing and calculating the dynamic thermal balance of an industrial steel rolling furnace, belonging to the technical field of detection. Background technique [0002] The industrial steel rolling furnace is a kind of heating equipment that uses fuel combustion for heating in the metallurgical industry. Its purpose is to make the billet reach the temperature required by the rolling process, while ensuring the heating quality of the billet. For this reason, the temperature of each section in the furnace is required to be controlled within a certain range, generally within ±10°C. The furnace consists of several heating sections, which are usually divided into heat recovery section, preheating section, heating section and soaking section to meet the temperature curve required by the billet heating process. The industrial furnace is the largest energy-consuming equipment in the steel rolling production process, accou...
