[0029] please participate figure 1 , is a flow chart of a method for predicting the thermal crown distribution of furnace rolls provided by an embodiment of the present invention. The following will be figure 1 The specific process shown will be described in detail.
[0030] Step S10: According to the degree of contact between the furnace roll and the steel strip, divide the furnace roll into N heat transfer modules along the width direction of the furnace roll, where N is a positive integer.
[0031] In step S10, the width direction of the furnace roll is a direction parallel to the central axis of the furnace roll.
[0032] In this embodiment, N can take a value of 3, and the heat transfer modules are divided according to the degree of contact between the furnace roll and the steel strip, and specifically can be divided into a first heat transfer module, a second heat transfer module, and a third heat transfer module; Wherein, the first heat transfer module is a part of t...
