Method for determining casting blank temperature and furnace entering temperature, storage medium and processor

Abstract

The invention provides a method for determining casting blank temperature and furnace entering temperature, a storage medium and a processor. The method for determining the temperature of the hot delivery and hot charging casting blank comprises steps S10, a casting blank model being established; S20, establishing an equipment model; S30, the corresponding relation between the casting blank modeland the equipment model is determined; S40, judging whether the step S10 to the step S30 are wrong or not, if at least one step is wrong, repeatedly executing the step S10 to the step S30, and if not,executing the step S50; S50, calculating a temperature field of the casting blank model, and determining a temperature evolution curve; and S60, whether the temperature evolution curve conforms to the temperature change curve or not is judged, if yes, the temperature of the casting blank being determined according to the temperature evolution curve, and if not, the step S10 to the step S50 beingexecuted repeatedly. According to the method, the temperature of the casting blank in the hot delivery and hot charging process can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of casting slab production, in particular to a method for determining the temperature of the slab and the temperature entering the furnace, a storage medium and a processor. Background technique [0002] The hot delivery and hot charging technology of continuous casting slab refers to the full and effective use of the sensible heat of continuous casting slab in the process of steelmaking-continuous casting-continuous rolling, and the hot continuous casting slab is directly or indirectly transported to the continuous casting slab. In the heating furnace of the rolling process, rolling is carried out after supplementary heat or soaking to achieve the purpose of greatly saving energy. The hot delivery and hot charging technology of continuous casting slabs turns steelmaking-continuous casting-continuous rolling into a closely linked integrated production system, which can not only greatly reduce energy consumpt...

Problems solved by technology

[0008] However, the estimation method (that is, the above-mentioned method of estimating the internal temperature of the tube blank based on the measured surface temperature of the tube blank) itself lacks scientific basis and rigor. The maximum temperature deviation of each mass point can reach about 180°C, and the temperature deviation of each mass point on the surface of the tube blank can reach about 100°C. Usually, when this estimation method is used, there is no clear measurement reference point, which makes the measurement itself at a loss.

The method of determining the furnace inlet temperature of the tube billet through the industrial test method has the disadvantages of large error, high cost and low efficiency
