Abstract

The invention provides a control method and a control system for the width centering of a steel coil carried by a steel coil car. The control system comprises a saddle seat position, a ground roll position, a drum, the steel coil car and a track for the traveling of the steel coil car, wherein a V-shaped saddle seat capable of lifting up and down is arranged on the steel coil car; an absolute value rope encoder is arranged below the track; a steel coil car retreat limit position travel switch, a steel coil car advance limit position travel switch and a steel coil car speed-reducing position travel switch are respectively mounted below the track; a coil-contacting approach switch, steel coil width detection correlation switches and a control module are further arranged above the track. The control system is simple, and accurate in width centering effect; and through the application of the control system, the degree of automation can be greatly improved, and the operating efficiency of a machine set can be improved.

Description

technical field [0001] The invention relates to a continuous processing technology of metallurgical cold rolling, in particular to a control method and system for centering the width of a steel coil carried by a steel coil car. Background technique [0002] The coil car of the cold rolling continuous processing line is one of the main equipment in the cold rolling process. The automatic control process of the steel coil car runs through the entire coiling process. If there is a problem in the calculation of the width of the coiling, it will affect the uncoiling and subsequent welding processes. In severe cases, the quality of the edge of the strip may be caused by the effect of the side guide problems, or even damage the equipment. Therefore, the automatic winding width alignment of the steel coil car must be accurate, timely, safe and reliable. This equipment plays a vital role in the entire processing line, and whether it can operate normally directly affects the product...
