The invention provides a temperature self-adaptive steel billet production method based on in-furnace verification. The temperature self-adaptive steel billet production method comprises the followingsteps of firstly acquiring cross section parameters, sizes and material density of billet materials, and then acquiring fulcrums of the billet materials and a space between the fulcrums; acquiring multiple supporting force data according to the length of the currently-segmented billet materials, and then obtaining uniformly-distributed load data of the billet materials; acquiring the maximum bending moment and the maximum deflection of a continuous beam and a cantilever beam to obtain maximum bending moment data and maximum deflection data of the billet materials; verifying the strength and the rigidity of the current billet materials; and acquiring current heating temperatures of the billet materials in real time, and adjusting the current heating temperatures according to the acquired strength data and the acquired rigidity data of the billet materials so as to finally obtain a product. The temperature self-adaptive steel billet production method disclosed by the invention has the advantages that a verification process of the in-furnace billet materials can be simplified, and the distribution accuracy of the billet materials is improved; and moreover, in the in-furnace heating process, heating can be adaptively adjusted according to the current temperature, the rigidity breakage and the flexibility deformation of the billet materials are reduced, and the production cost canbe greatly reduced while the heating quality and the safe production of steel billets can be ensured.

technical field [0001] The invention relates to the technical field of billet production by a continuous heating furnace, in particular to a temperature-adaptive steel billet production method based on furnace calibration. Background technique [0002] Continuous heating furnace is a common equipment for billet heating production. Under the existing technology, continuous heating furnace generally includes pusher type heating furnace and walking beam type heating furnace. The continuous heating furnace in which the billet moves in the furnace, while the walking beam heating furnace is a continuous heating furnace that relies on the rising, advancing, descending and retreating actions of the metal beam to move the billet forward step by step. Nowadays, with the innovation of technology, the water-cooled beams in the furnace are installed in the walking beam type heating furnace and the steel pusher type heating furnace, and the water-cooled beam in the furnace moves in the fu...

Problems solved by technology

[0005] However, in the method of preparation and arrangement of the above-mentioned shooting water-cooled beams proposed in the prior art, there is a lack of rigorous calculation process in the process of confirming the cross-section parameters of the water-cooled beams. Data for confirmation of section parameters of water-cooled beams

With the innovation of technology and the continuous improvement of production needs, the types and specifications of the blanks in the heating furnace are different in actual production. In the process, according to different heating process systems of different types and specifications of blanks, it is necessary to repeatedly try to calculate the cross-sectional parameters of the water-cooled beams and then repeatedly adjust the layout of the water-cooled beams in the furnace and the layout of the blanks. In this process, on the one hand , the trial calculation process is cumbersome and lengthy, and since the confirmation of the cross-section parameters of the water-cooled beam is mostly based on experience and previously stored data, the accuracy of the data results obtained in the trial calculation process is poor; on the other hand, with the demand for production speed and rhythm It is obvious that the arrangement method in the above-mentioned prior art needs a large amount of manpower, and at the same time causes a substantial extension of the production cycle

[0006] In addition, in the heating process of the above-mentioned production process, the billet is usually controlled to be heated to the ideal temperature. However, in the actual heating process, the section coefficient, maximum bending moment and maximum deflection of the billet will affect the current heating temperature, resulting in the actual heating temperature. There is a certain deviation from the ideal temperature, and the existing technology lacks effective means to detect the current heating temperature, making it even more difficult to adjust the thermal load in the furnace according to the current heating temperature; at the same time, the structure of the water-cooled beam also affects the heating energy consumption in the furnace, the heating furnace Service life, cross-sectional temperature difference and heating quality of the heated blank
