Problems solved by technology

[0002] At present, the only missing link in the automatic rolling system that requires manual intervention is the steel transfer function. Usually, in order to produce steel plates of any width from several fixed-sized billets, the medium-heavy plate rolling mill sets the rolling pass In the state, the steel transfer operation will be added. During the steel transfer pass, the operator switches from the automatic steel rolling mode to the manual mode for steel transfer. After the manual steel transfer is completed, manual confirmation is required to return to the automatic steel rolling state again. Human intervention is an external disturbance of the automatic steel rolling system, which affects the stable production process of high-grade products with high requirements on production technology

Abstract

The invention relates to an automatic steel rotation method for medium plates, which belongs to the technical field of steel rolling. The method comprises the following steps of: 1, performing acquisition on a plate blank image; 2, performing edge detection on the plate blank image; 3, performing image distortion and calibration processing; 4, performing image binarization; 5, performing plate blank boundary tracking to obtain a boundary point set; 6, performing linear detection on plate blank boundary and calculating an rotating angle of a plate blank; 7, driving a steel rotation conical roller bed for steel rotation; 8, performing judgment of steel rotation in-place; 9, performing processing of steel rotation timeout; and 10, performing processing of steel rotation completion. The method has the advantages that the method has simple equipment installation and quick detection speed, can execute one-time detection and control within 100 ms, is based on an industrial Ethernet interface and basic automation communication, has stable and reliable steel rotation process, and is suitable to be embedded into an automatic steel rolling system of the medium plates for application.

Description

Technical field: [0001] The invention belongs to the technical field of steel rolling, and particularly relates to an automatic steel transfer method for medium and heavy plates. Background technique: [0002] At present, the only missing link in the automatic steel rolling system that requires manual intervention is the steel transfer function. Generally, in order to produce a steel plate of any width from several fixed-size billets, a plate rolling mill is required to formulate rolling passes. The steel transfer operation will be added when the steel transfer is performed. When the steel transfer pass is performed, the operator switches from the automatic steel rolling mode to the manual steel transfer mode. After the manual steel transfer is completed, manual confirmation is required to restore the automatic steel rolling state again. The steel transfer process The human intervention is the external disturbance of the automatic steel rolling system, which affects the stab...
