Core Viewpoint - The launch of the φ530mm skew rolling pipe production line by Taiyuan Heavy Machinery Group marks a significant breakthrough in China's large-diameter medium-thick wall seamless steel pipe equipment sector, filling a gap in the international market and showcasing the achievements of independent innovation in high-end equipment [1][3]. Group 1 - The φ530mm skew rolling pipe production line is the first of its kind in China and the largest globally [1]. - This production line employs a "dual closed-loop + dual circuit hydraulic" collaborative control system, achieving precise and stable control throughout the rolling process [2][3]. - The pressure closed-loop system features millisecond-level rapid response capabilities, effectively addressing deformation issues during the pipe finishing stage [2]. Group 2 - The motor system of the production line adopts a grouped centralized control mode, which reduces investment costs and lowers operational energy consumption [2]. - The production rhythm has improved from the traditional 3 minutes per pipe to 1.5 minutes, effectively doubling the production capacity while also reducing gas consumption [2].
