Embodiment Construction

[0038] In order to better understand the above technical solutions of the present invention, a further detailed description will be given below in conjunction with the drawings and embodiments.

[0039] Please refer to FIG. 2 , the process parameter setting method of the straightening roll of the tension leveling machine unit of the present invention is mainly based on the multi-layer feed-forward neural network structure of the back propagation learning method to set the parameters of the straightening roll. In fact, the method of the present invention has selected the comparatively mature and commonly used BP neuron network structure in the artificial neuron network tool. .

[0040] Method of the present invention is specified as follows:

[0041] First of all, the training sample parameters of the artificial neural network are selected and determined, and the relevant data of the steel plate to be corrected are selected, including the wave shape data of the strip steel, th...

Abstract

The invention discloses a kind of setting method for processing parameter of correct roller of withdrawal straightening stands based on spot measured data and analysis result, and the shape of steel sheet at the export of withdrawal straightening stands is good as standard, and it chooses the relative data with representation as the training sample parameter of artificial nerve network, and combines the characteristics of withdrawal straightening stands to choose the skilled and general reversing transmission nerve network. The good operation experience is converted into mathematical model to build the setting method for processing parameter under different steel rule and material. The invention can overcome the problems that the setting of processing parameter of traditional spot withdraw is short of theory, and the result is not ideal, and the invention fits for the production characteristics, it has good withdraw effect and satisfy the requirement for producing the production with high quality.

Description

technical field [0001] The invention relates to the straightening of cold-rolled plate shape after strip cold-rolling treatment, and more specifically refers to a process parameter setting method for straightening rolls of a tension leveling machine unit. Background technique [0002] For cold-rolling post-processing units, such as hot-dip galvanizing and continuous annealing units, a tension-leveler is usually installed behind the skin pass mill to improve the shape quality of the strip. The structure of the general tension-leveler is shown in Figure 1. The straightening machine is composed of 1# bending roller group 11, 2# bending roller group 12, longitudinal straightening roller 13 and transverse straightening roller 14. Under a certain elongation, by setting the different insertion amounts of these rollers, different bending and stretching of the strip is formed, thereby improving the shape of the strip. [0003] At present, the setting values ​​of the process paramete...
