Embodiment 1

[0027] In the specific implementation process, a second-level process simulation method for hot continuous rolling strip shape is described. Based on a set of off-line platform, the method simulates the calculation process of the hot continuous rolling secondary shape model, and accurately reproduces the on-site continuous rolling process.

[0028] See below figure 1 , is the flowchart of the second-level process simulation method for hot strip shape.

[0029] The method comprises the steps of:

[0030] Step A, loading the static data of the current steel strip.

[0031] Specifically, the current static data of the steel strip includes properties of the steel type, characteristics of the stand, parameters of the roll, primary data, instrument measurement data, and secondary setting parameters.

[0032] Step B, loading the dynamic data of the current steel strip.

[0033] Specifically, the dynamic data of the current strip is the relevant data obtained after rolling the pre...

Abstract

The invention discloses a two-stage process simulation method for hot continuous rolling strip: step A, loading the static data of the current strip steel; the current static data of the strip steel includes steel type attributes, frame characteristics, roll parameters, primary Data, meter measurement data, and secondary setting parameters; step B, loading the dynamic data of the current strip; wherein, the dynamic data of the current strip is specifically: the relevant data obtained after rolling the previous strip; step C , according to the static data of the current strip and the dynamic data of the current strip, the initial calculation of the roll model is performed; step D, the initial calculation of the flatness model is performed; step E, the calculation of the trigger roll model is performed; step F, the flatness model is triggered Carry out the calculation; step G, store the relevant data obtained for the current strip in the dynamic data, and use it for rolling the next strip; step H, after the calculation of the current strip is completed, trigger the next strip to execute steps A to Contents in step G.

Description

technical field [0001] The application relates to the analysis and control technology of the hot continuous rolling process of strips, and in particular to a secondary process simulation method of hot continuous rolling strip shape. Background technique [0002] With the rapid development of the automobile, can making and home appliance industries, the market not only has a sharp increase in the demand for plate and strip, but also puts forward stricter requirements for its shape quality, dimensional accuracy and performance. Shape is an important product process index of hot-rolled thin plate. Among them, the shape secondary control model system has become the key technology to ensure the quality indicators of products in modern strip production. An effective and accurate simulation method of the flatness secondary process model of hot continuous rolling is a necessary condition and an important guarantee for the study of the flatness process and control system. At present...
