Abstract

Seamless steel pipes are widely used in oil and gas transportation, marine engineering, mechanical manufacturing, and infrastructure industries, where wall thickness accuracy is critical to quality, safety, and service life. Most domestic continuous tube mills are equipped with offline wall thickness inspection systems, relying on manual parameter adjustments, which suffer from issues such as delayed regulation, poor accuracy, low material yield, and heavy reliance on manpower. This study explores real-time closed-loop feedback control technology for hot-rolled blank pipe wall thickness, establishing an integrated process model that incorporates functions like online wall thickness deviation diagnosis, roll gap adaptive adjustment, rotational speed dynamic optimization, and model instant correction. This technology fills the domestic gap in real-time closed-loop control for continuous tube wall thickness, providing a mature localized solution for intelligent upgrading of seamless steel pipe production lines and quality improvement of high-end pipe materials.
