Problems solved by technology

[0002] During the galvanizing process, due to the problem of the raw material of the strip steel, there may be warp deformation and large differences in galvanizing thickness after the zinc pot is discharged. This uneven steel strip will damage the subsequent air knife, thickness measurement, Finishing and straightening machine rollers and other equipment, and the occurrence of such defects has a greater impact on the quality of finished products

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] see Figure 1-3 , a galvanizing line strip galvanizing defect tracking method, comprising the following steps:

[0029] S1: While marking the strip defects, the operator records the relative position of the strip defects;

[0030] S2: Record the location of each defect in the same strip;

[0031] S3: After the steel strip comes off the assembly line, all positions of the steel strip are cleared;

[0032] S4: Through the encoder and computer system, m...

Abstract

The invention discloses a tracking method for galvanizing defect of galvanizing wire strip steel, which comprises the following steps: when an operator marks the defect of the strip steel, the relative position of the defect of the strip steel is recorded; the position is recorded for each defect generated by the same strip steel; the position of the defect is recorded for each defect generated bythe same strip steel; after the strip is disconnected, all positions of the strip are cleared; through encoder and computer system, the linear velocity of strip steel is measured and the relative distance between each defect and air knife, thickness gauge, finisher, straightener, roll coater, disc shears and flying shears is calculated. The method for tracking the defect of galvanizing strip steel of the galvanize line records the defects of each strip steel, records their positions, and calculates the relative positions of the defects and subsequent pneumatic knives, thickness gauges, finishing machines, straighteners, roll coaters, disk shears, and flying shears, so that before the defects arrive, the relevant equipment can act to avoid the defects, so that the strip steel defects do not damage the equipment and reduce the interference of the defects on the equipment.

Description

technical field [0001] The invention relates to the technical field of material tracking of a continuous hot-dip galvanizing line, in particular to a method for tracking galvanized defects of strip steel on a galvanizing line. Background technique [0002] During the galvanizing process, due to the problem of the raw material of the strip steel, there may be warp deformation and large differences in galvanizing thickness after the zinc pot is discharged. This uneven steel strip will damage the subsequent air knife, thickness measurement, Finishing and straightening machine rolls and other equipment, and the occurrence of such defects has a greater impact on the quality of finished products. Therefore, once a defect occurs, being able to track its location and process it is the key to protecting the equipment on the line and improving the yield. Contents of the invention [0003] The object of the present invention is to provide a kind of galvanizing line strip galvanizing...
