Embodiment Construction

[0042] The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] like figure 1 As shown in the figure, the method for calculating the tension and wrap angle setting of the whole-roll flatness detection roller includes the following steps:

[0044] S1, establish an x-y Cartesian reference coordinate system, and select four points as the initial axis positions of each roller in a four-roller structure;

[0045] Preferably, the coordinates of four points in S1 are selected as a four-roller structure, the strip is covered with a four-roller structure, and each roller structure is a plate-shaped d...

Abstract

The present invention relates to the technical field of cold-rolled strip shape detection, in particular, to a method for calculating the tension and wrap angle setting of a full-roll type shape detection roll, including the following steps: S1, establishing an x-y Cartesian reference Coordinate system; S2, given shape detection roller radius R 1 and the angle size 2θ of the strip cladding roll 1 , calculated to satisfy the current wrap angle 2θ 1 The drive roller radius R 2 ; S3, given the strip tension T, strip elastic modulus E; strip width B; strip thickness h, calculate the corresponding current wrap angle 2θ 1 and the applied load F at the axis of the driving roller due to the strip tension T; S4, according to the calculated parameters and the calculated radius R of the driving roller 2 And apply the load F to build a test platform or a simulation model for testing. The invention calculates the tension and wrap angle of the plate-shaped roll accurately and quickly.

Description

technical field [0001] The invention relates to the technical field of cold-rolled strip shape detection, in particular, to a calculation method for the setting of roll tension and wrap angle for whole-roll type shape detection rolls. Background technique [0002] Cold-rolled strip is widely used in industrial manufacturing sectors such as automobiles, home appliances, construction and electronics due to its remarkable advantages of high performance and high precision. It is also an important symbol of the country's industrialization level. Flatness is an important quality indicator for cold-rolled strips. Poor flatness will not only cause difficulties in the subsequent processes, but also lead to accidents such as roll strangulation and strip breakage, and even damage to the rolling mill in severe cases. [0003] At present, China's steel production capacity is overcapacity, and the domestic steel industry is generally undergoing technological transformation. Even companie...
