2025year11moon，Taiyuan Heavy Machinery Group Co., Ltd（Taizhong Group）The world's first research and development projectφ530AsselThe inclined rolling pipe production line has been officially put into operation，This marks a significant breakthrough for China in the field of large-diameter, medium thick walled seamless steel pipe equipment。
This production line adopts“dual closed-loop+Dual circuit hydraulic system”Collaborative control system，The response speed of the pressure closed-loop system reaches millisecond level，Thoroughly solve the problem of deformation at the end of steel pipes，The production rhythm starts from each individual3Minute increase to1.5minute，Double production capacity。
The motor system adopts a group centralized control mode，Reduced investment costs15%，Decreased power consumption during operation20%，Reduced gas consumption18%，Becoming a benchmark case for global green manufacturing。
Technical Highlights：
φ530AsselThe core of the inclined rolling pipe production line lies in its“dual closed-loop+Dual circuit hydraulic system”control system。The system monitors the position and rolling force of the rolling mill in real-time，Realize precise and stable control throughout the entire process，Especially solved the high scrap rate caused by deformation during the final stage of steel pipes in traditional production lines、Low dimensional accuracy issues。Besides，Intelligent temperature control system equipped on the production line，The fluctuation of rolling temperature can be controlled within±2℃within，Ensure the uniformity of pipe organization，Significantly improve fatigue resistance performance。
industry impact：
The commissioning of this production line，Not only does it fill the gap in the international market for large-diameter, medium thick walled seamless steel pipe equipment，Further promote China's transition from“Steel pipe country”to, toward, at, facing“Equipment powerhouse”cross。According to industry experts' analysis，φ530AsselThe success of the production line，Will drive domestic seamless steel pipe equipment towards“premiumization、intelligentization、greening”upgrade，expected future3within the year，Similar technologies will cover the domestic market50%The above large-diameter seamless steel pipe production line，Drive industry capacity utilization from the current level70.85%upgrade to85%above。
