Materiel tracking system of ERW welded pipe product line

Abstract

The present invention relates to a material tracking method in manufacturing process of ERW welding tube. In the manufacturing process of ERW welding tube, all production processes from raw material hot rolling bending, longitudinal shearing strips, ERW tube welding, fine-finishing after welding, wholly quenching and tempering, tube processing, etc. are executed with material welding. In the processes realized with material tracking, the facilities of bar code printing and scanning, on-line jet printing, automatic generating of sequence number of steel tube, pipe end lettering, steel tube data collecting, production management, etc. are used for recording, coding, identifying, marking and controlling each procedure in the production process of welding tube from raw material to finished tube for obtaining effectively recording main parameter of each unit assembly of each steel tube in the production process, matching with a nondestructive flow detection device for recording and marking the defect existing in the raw material, half-finished product and finished product, thereby realizing the tracking to the production process of each steel tube. The analysis to reason for the generation of defective product, the time, the personnel of production group and the contemporary process parameter can be realized. The problem can be found and settled in time. The production management and examination are facilitated.

Description

Technical field: [0001] The invention relates to a material tracking system, in particular to a material tracking system for an ERW welded pipe production line. Background technique: [0002] In the production process of ERW welded pipes, the pipe material tracking system has always been a difficult problem to solve. The manufacturing process of ERW welded pipes has been from raw material hot-rolled coils, slitting, ERW formed welded pipes, flying saws, post-weld finishing, heat treatment, In the production process of pipe processing and other processes, there are many process links, and various defects will occur in the production process. Equipment often breaks down. The phenomenon of mixing steel with different specifications and types of steel. And it is impossible to distinguish the steel pipes produced by different steel coils. If the steel strips of the same specification and different materials are wrongly loaded on the ERW welded pipe production line, and they are ...

Problems solved by technology

However, most of the domestic ERW welded pipe factories do not have this condition

No ERW welded pipe factory has really realized material tracking in the whole production process
