Embodiment 1
[0044] This embodiment provides a method and device for determining the transmission torque of a cold rolling mill. The method includes:
[0045] S110, obtaining the average radius of the work rolls of the cold rolling mill, the flattening radius of the work rolls, the rolling force to be rolled by the cold rolling mill, the entrance thickness of the strip, and the exit thickness of the strip;
[0046] In this step, the average radius of the work rolls of the cold rolling mill, the flattening radius of the work rolls, the rolling force to be rolled of the cold rolling mill, the entrance thickness of the strip and the exit of the strip are obtained Thickness; here, because the cold rolling mill includes the upper working roll and the lower working roll, the radius of the upper and lower working rolls is different, so the average value of the radius of the upper and lower working rolls should be taken, that is, the average radius of the working rolls of the cold rolling mill.

Embodiment 2
[0082] Corresponding to Embodiment 1, this embodiment provides a device for determining the transmission torque of a cold rolling mill, such as figure 2 As shown, the device includes: a first acquisition unit 21, a first determination unit 22, a second determination unit 23, a second acquisition unit 24, a third determination unit 25, a third acquisition unit 26, a fourth determination unit 27, The fifth determining unit 28; wherein,
[0083] The first acquisition unit 21 is used to acquire the average radius of the work rolls of the cold rolling mill, the flattening radius of the work rolls, the rolling force of the cold rolling mill to be rolled, the entrance thickness of the strip, and the The outlet thickness of the strip steel; here, because the cold rolling mill includes the upper work roll and the lower work roll, and the radii of the upper and lower work rolls are different, it is necessary to take the average value of the radii of the upper and lower work rolls, that...
Embodiment 3
[0115] In actual application, when using the determination method provided in Embodiment 1 and the determination device provided in Embodiment 2 to determine the transmission torque of a certain unit price cold rolling mill, the details are as follows:
[0116] Obtain the average radius of the work rolls of the cold rolling mill, the flattening radius of the work rolls, the rolling force to be rolled in the cold rolling mill, the entrance thickness of the strip and the exit thickness of the strip; here, Because the cold rolling mill includes the upper working roll and the lower working roll, and the radii of the upper and lower working rolls are different, it is necessary to take the average value of the radii of the upper and lower working rolls, that is, the average radius of the working rolls of the cold rolling mill.
[0117] In this embodiment, the average radius of the work rolls is 36mm, and the flattening radius of the work rolls is: 40.44mm. The rolling force to be rol...
