Embodiment 1

[0039] This embodiment provides a method for detecting the consistency of furnace temperature in a continuous heating furnace, comprising the following steps:

[0040] Step 1. Set the temperature test point:

[0041] In this embodiment, a bearing steel billet is used as the test billet. The bearing steel is a high-carbon steel with relatively poor thermal conductivity. There is a temperature difference between the internal and surface temperatures of the billet, which can better reflect the actual heating capacity and temperature consistency of the heating furnace.

[0042] The size of the test billet is based on the size of the hearth of the continuous heating furnace, which should be able to cover all heating areas, especially the length can reflect the heating effect of different positions in the furnace. The size of the test billet used in this example is 250mm*280mm*7270mm .

[0043] First, a total of 9 temperature measurement points are set up on the test billet. Selec...

Abstract

The invention relates to a method for detecting the consistency of the furnace temperature of a continuous heating furnace, and belongs to the technical field of temperature detection of a heating rolling production line. In order to solve the problem that an existing temperature detection method cannot accurately measure the consistency of the furnace temperature of the heating furnace, the invention provides the method for detecting the consistency of the furnace temperature of the continuous heating furnace. The detection method comprises the following steps of: setting a temperature testing point, assembling a temperature testing device, detecting a steel billet put in the furnace and evaluating the consistency of the furnace temperature. According to the detection method, a temperature-measuring instrument and the steel billet synchronously enter the heating furnace so as to be heated; the temperatures of the surface layer and the interior of the steel billet are recorded in realtime; parameters such as the heating temperature curve of the steel billet in the continuous heating process, the tapping temperature, the temperature difference of the surface layer and the interiorof the steel billet, the temperature difference in the length direction and the like can be accurately detected; and based on the parameters, the temperature consistency of the continuous heating furnace is comprehensively and accurately measured, and thus, the scientific, accurate and reliable data basis is provided for the production and acceptance of the continuous heating furnace, the establishment and verification of mathematical models, and the datamation of the heating furnace process.

Description

technical field [0001] The invention belongs to the technical field of temperature detection of a heating and rolling production line, and in particular relates to a detection method for the furnace temperature consistency of a continuous heating furnace. Background technique [0002] The heating quality of steel billet is directly related to the quality, output, energy consumption and service life of mechanical equipment of steel products. Improving the heating quality of steel billet can improve the plasticity of steel, reduce the resistance during thermal processing, and reduce fuel consumption and oxidation loss. Whether the heating furnace can ensure safe and normal operation, and whether it can heat up qualified steel billets through standardized operations plays an important role in determining whether the entire rolling line can maintain safe and continuous production. The uniformity of the furnace temperature field is an important factor to measure and ensure the he...
