4, according to upper surface temperature when coming out of the stove of steel billet to be measured described in every piece, being averaged for every block of steel billet to be measured is obtained
Temperature.Specifically, can be according to heat flux, heat flow density etc., and mean temperature is calculated by gridding method, calculation method is correlation
The prior art that technical staff can directly adopt, details are not described herein.Finally, based on the prediction of second level steel billet temperature computation model
The mean temperature of steel billet in heating furnace can be adjusted amendment (for example, fire box temperature etc.) to the heating parameters of heating furnace,
To guarantee the accuracy of the heating temperature for the steel billet to be measured being heated, the qualification rate of steel billet to be measured is improved;Until prediction
The mean temperature of steel billet meets the requirements, then illustrates to correct successfully, can stop the adjustment of heating furnace relevant parameter.
In the present embodiment, when as soon as should be at interval of period t, the prediction of a mean temperature be carried out to steel billet to be measured,
To guarantee in time to be adjusted the heated condition of heating furnace.After gap periods t, step S10-S40 is continued to execute, wherein the
One moment replace with (when the first moment+period t), first object steel billet be (when the first moment+period t) be located at it is described N number of
Steel billet in measurement position, and so on, it repeats no more.
The upper surface temperature of the first, second target steel billet will be directly measured in method provided by the invention as feedback
Value, and the furnace gas temperature and fire box temperature of multiple measurement positions in heating furnace are further obtained, measurement at this time is not deposited
In other processes, lag is smaller, and the upper surface temperature for the first, second target steel billet come out of the stove all can be to be measured in subsequent heat
