Steel coil longitudinal shearing flow quality control system and method based on cloud service

Abstract

The invention belongs to the technical field of steel coil longitudinal shearing flow quality control, and discloses a steel coil longitudinal shearing flow quality control system and method based on cloud service. The steel coil longitudinal shearing flow quality control system based on the cloud service comprises a longitudinal shearing data acquiring module, a central control module, a data comparison module, a longitudinal shearing adjustment module, a thickness control module, a tension control module, a quality assessment module, a cloud service module and a display module. The strip steel total thickness control precision can be improved through the thickness control module, so that such product quality problems as tower shapes and coil collapse of steel coils are eliminated; and meanwhile, the tension control module is associated with five factors of the steel coil material yield strength, the strip steel interlayer maximum static friction coefficient, the winding drum equipment capacity, the equipment state and the strip steel sectional area in an unit strip penetrating tension calculating formula to quickly give out a better winding tension control value, so that the defects of heart coils, coil collapse and coil looseness are reduced.

Description

technical field [0001] The invention belongs to the technical field of quality control of steel coil slitting process, and in particular relates to a cloud service-based steel coil slitting process quality control system and method. Background technique [0002] Steel coil, also known as coil steel. The steel is hot-pressed and cold-pressed into rolls. In order to facilitate storage and transportation, it is convenient to carry out various processing (such as processing into steel plates, steel strips, etc.). Formed coils are mainly hot rolled coils and cold rolled coils. Hot rolled coil is a processed product before billet recrystallization. Cold rolled coil is the subsequent processing of hot rolled coil. The general weight of steel coil is about 15-30T. Since the slitting process of steel is becoming more and more refined, and customers have higher and higher requirements for the quality of slitting finished products, especially for the high-end customers in the auto...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: the thickness control accuracy of existing steel coils is poor; at the same time, the coiling tension is not well controlled, resulting in defects of heart-shaped coils, collapsed coils, or uncoiled coils, which affect the yield, especially Heart-shaped roll defect, in severe cases, the entire roll may even be scrapped because it does not meet the requirements of the next process and the roll up
