Abstract

The invention belongs to the technical field of steel reel measurement and discloses an inserting coil steel reel diameter measuring method. The method comprises steps of acquiring a vertical height (H3) of an axle wire of a recoiling machine dabber, a vertical height (H1) of an axle wire of each steel reel trolley cradle roller, a radius (r) of the steel reel trolley cradle roller, and a distance (H2) between the centers of two cradle rollers on the steel reel trolley, acquiring a displacement (Y) of the steel reel trolley when the steel reel trolley vertically moves upward until the steel reel trolley cradle rollers are abutted against the outer wall of the steel reel, building a mathematic calculation module based on the vertical height (H3) of the axle wire of the recoiling machine dabber, the vertical height (H1) of the axle wire of each steel reel trolley cradle roller, the radius (r) of the steel reel trolley cradle roller, and the distance (H2) between the centers of the two cradle rollers on the steel reel trolley as well as the acquired displacement (Y) of the steel reel trolley, and acquiring a calculating formula between a steel reel radius (R) and the displacement (Y) of the steel reel trolley according to the mathematic module. The invention provides a high-efficient inserting coil steel reel measuring method.

Description

technical field

[0001] The invention relates to the technical field of steel coil measurement, in particular to a method and system for measuring the diameter of an off-line steel coil. Background technique

[0002] At present, most of the calculation of the diameter of the off-line steel coil is calculated by using the angular velocity ratio of the coiler and the steering roll or adding a diameter measuring device in the saddle area of ​​the off-line.

[0003] One of these two traditional methods is affected by tension fluctuations, slippage or other abnormal conditions in the production process, and the accuracy is poor; the other requires additional measuring equipment, increases the cost of investment, and occupies a large amount of narrow space in the exit area , It is easy to collide when lifting the coil. Contents of the invention

[0004] The invention provides a method and system for measuring the diameter of an off-line steel coil, which solves the technical pro...
