Pangang Group Overcomes Technical Barrier in 0.8mm Thin-Gauge Titanium Material Pickling

Recently, the 0.8mm titanium pickling coil developed by Panzhihua Iron & Steel Group Xichang Panxin Vanadium-Titanium Metal Materials Co., Ltd. (hereinafter referred to as "Panxin Vanadium-Titanium") was successfully rolled off the production line. This product not only sets a new record for the thinnest specification of titanium pickling processed by Panzhihua Iron & Steel Group, but also marks a key technological leap forward in the high-end titanium processing sector for the Group.

Since 2025, Panxin Vanadium-Titanium has focused on process upgrades and quality improvements, accelerating the iteration of product technologies and the development of new products. To overcome the bottleneck in processing thin-gauge titanium materials, the company established a special pickling task force, collaborating with technical teams such as the Panzhihua Iron & Steel Group Research Institute. Through a series of innovative measures, they overcame multiple technical barriers in continuous production. In terms of technological innovation, Panxin Vanadium-Titanium constructed a three-dimensional control system integrating "process parameters + equipment operation + quality monitoring," combined with an intelligent mapping model of "process parameters + quality indicators," achieving precise control over the entire production process. The company developed six core technologies, including precise weld seam control, dynamic tension compensation, and intelligent acid circulation, pushing the titanium coil pickling process beyond the 1mm design limit of the equipment unit and achieving a dual improvement in production efficiency and quality.

Upon detection, the 0.8mm pickled titanium product rolled off the line achieved a 100% qualification rate, with a comprehensive finished product rate of 98.5% and a surface defect rate below 3%, surpassing the internationally accepted full-length control standard of 5%. A series of data highlights Panzhihua Iron & Steel Group's leading strength in the high-end titanium processing sector. According to the project leader, during the technological development process, the R&D team systematically refined a technical specification system of 15 key process standards, providing reliable technical support for the subsequent development of ultra-thin-gauge products and further promoting the application of Panzhihua Iron & Steel Group's titanium materials in high-end markets such as nuclear power, aviation, and marine engineering.

Currently, Panxin Vanadium-Titanium has joined forces with institutions such as the Institute of Metal Research, Chinese Academy of Sciences, to launch the second phase of the technological breakthrough plan, focusing on the R&D of laser cleaning as an alternative to pickling processes. This technological innovation aims to drive the titanium processing industry towards greener and smarter upgrades, injecting new momentum into the construction of Ansteel Group's core supporting capabilities as the leader of the titanium and new materials industry chain.

The breakthrough in the 0.8mm titanium pickling technology represents a significant milestone for Panzhihua Iron & Steel Group in the high-end titanium sector. Looking ahead, Panzhihua Iron & Steel Group will continue to prioritize innovation-driven development, deepen technological upgrades and product iterations, and contribute more "Panzhihua Iron & Steel Group solutions" to the high-quality development of China's titanium industry.
