Embodiment Construction

[0064] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] Such as figure 1 Shown is the heat balance block diagram of the steel rolling industrial furnace. The heat supplied by the steel rolling industrial furnace is mainly the chemical exothermic heat generated by fuel combustion, and its effective heat is the physical heat taken away by the heated billet, and the smoke is taken away and the furnace wall is lost. loss from figure 1 It can be seen that the three are in line with the energy balance relationship.

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

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

[0068] First, collect various raw data related to heat income an...

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 heat balance of a steel rolling industrial furnace, belonging to the technical field of detection. Background technique [0002] The steel rolling industrial furnace is a kind of heating equipment that uses fuel combustion for heating in the metallurgical industry. Its purpose is to make the steel billet reach the temperature required by the steel rolling process, and at the same time ensure the heating quality of the steel 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 is composed of several heating sections, usually divided into heat recovery section, preheating section, heating section and soaking section to meet the temperature curve required by the billet heating process. Industrial furnaces are the largest energy-consuming equipment in the steel rolling product...
