Abstract
The invention discloses a self-adaptive control method and device. The embodiment of the invention discloses a self-adaptive control method and device for preventing strip steel from being expanded and narrowed by pulling. The self-adaptive control method and device is used for regulating a vertical rolling mill to regulate width of the strip steel, so that width of produced strip steel meets production requirements. The self-adaptive control method is applied to a hot-rolled strip steel system. The hot-rolled strip steel system comprises the vertical rolling mill and a coiling machine. The method comprises the following steps of: determining attribute parameters of strip steel to be treated by the hot-rolled strip steel system and a to-be-worked coiling machine; determining adaptive regulating parameters from a regulating parameter table based on the attribute parameters and the to-be-worked coiling machine, wherein the regulating parameter table comprises regulating parameters adaptive to the attribute parameters of the strip steel and the coiling machine, and regulating the vertical rolling mill according to the regulating parameters; and when the to-be-worked coiling machine works, rolling the to-be-treated strip steel through the regulated vertical rolling mill.
Description
technical field [0001] The invention relates to the technical field of steel rolling, in particular to an adaptive control method and device. Background technique [0002] The rolling process of hot-rolled strip steel is to heat the slab to the rolling temperature through the heating furnace, and then roll the slab into thin strip steel after passing through the vertical roller mill, rough rolling mill and finishing mill. The thin strip steel reaches the target coiling temperature after passing through the laminar flow cooling device, and finally coils into steel coils through the coiler. Since the strip steel will generate tension when it enters the coiler, it will cause the strip steel to be stretched between the finishing mill and the coiler. Since the temperature of strip steel usually drops by 200 to 300 degrees after laminar flow cooling, there will be stronger stiffness after the laminar flow cooling section, and the stretching of the strip steel will be manifested w...
