Good news! On July 10, the hot rolling production line of Guangqing Technology Rolling Plant successfully achieved stable rolling of 200 series stainless steel (Price) with extremely thin specifications, and the thinnest product can reach 1.55mm! This production not only broke through the design limit specifications of this steel type, but also became the first case of successful production of this thin specification in the conventional hot rolling field, with the achievement of continuous and stable rolling!
How to stably roll a 220mm thick slab into a finished product of only 1.55mm, break through the design limits of the rolling mill, and enhance product competitiveness is the core topic that the company's rolling mill team has been working on for a long time. Faced with the challenge, the production process, mechanical, electrical, automation, and other professional teams of the rolling mill worked closely together, and carried out multiple rounds of in-depth discussions and systematic tests around equipment parameters and operating procedures. By optimizing heating, breaking through the traditional transmission speed limitations in the rough rolling area, and deeply optimizing the finishing rolling force model, the stability of thin-gauge rolling and the quality of plate shape were ensured. After months of continuous research, the production line successfully overcame a series of technical bottlenecks and finally achieved the stable production of 1.55mm ultra-thin 200 series stainless steel!
The success of this continuous and stable rolling indicates that the 200 series stainless steel 1255×1.55mm specification has the ability to be mass-produced stably. Its complete research path and solution also provide technical experience for the company's other cost reduction and efficiency improvement and process limit breakthrough projects. In the context of the current downward pressure on the industry, Guangqing Technology has achieved breakthroughs in key process links through active innovation, effectively enhancing the company's competitiveness in the high-end thin-gauge stainless steel market.
